Rest Unicode C Reference Documentation

Rest

Current Version: 9.5.0.75

API for implementing RESTful Web API's.

Create/Dispose

HCkRestW instance = CkRestW_Create();
// ...
CkRestW_Dispose(instance);
HCkRestW CkRestW_Create(void);

Creates an instance of the HCkRestW object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.

void CkRestW_Dispose(HCkRestW handle);

Objects created by calling CkRestW_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkRestW_Dispose.

Callback Functions

Callback Functions introduced in Chilkat v9.5.0.56
void CkRestW_setAbortCheck(HCkRestW cHandle, BOOL (*fnAbortCheck)(void));

Provides the opportunity for a method call to be aborted. If TRUE is returned, the operation in progress is aborted. Return FALSE to allow the current method call to continue. This callback function is called periodically based on the value of the HeartbeatMs property. (If HeartbeatMs is 0, then no callbacks are made.) As an example, to make 5 AbortCheck callbacks per second, set the HeartbeatMs property equal to 200.

void CkRestW_setPercentDone(HCkRestW cHandle, BOOL (*fnPercentDone)(int pctDone));

Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This callback is only called when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For methods that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).

This callback counts as an AbortCheck callback, and takes the place of the AbortCheck event when it fires.

The return value indicates whether the method call should be aborted, or whether it should proceed. Return TRUE to abort, and FALSE to proceed.

void CkRestW_setProgressInfo(HCkRestW cHandle, void (*fnProgressInfo)(const wchar_t *name, const wchar_t *value));

This is a general callback that provides name/value information about what is happening at certain points during a method call. To see the information provided in ProgressInfo callbacks, if any, write code to handle this event and log the name/value pairs. Most are self-explanatory.

void CkRestW_setTaskCompleted(HCkRestW cHandle, void (*fnTaskCompleted)(HCkTaskW hTask));

Called in the background thread when an asynchronous task completes. (Note: When an async method is running, all callbacks are in the background thread.)

Properties

AllowHeaderFolding
BOOL CkRestW_getAllowHeaderFolding(HCkRestW cHandle);
void CkRestW_putAllowHeaderFolding(HCkRestW cHandle, BOOL newVal);
Introduced in version 9.5.0.63

If this property is set to FALSE, then no MIME header folding will be automatically applied to any request header. The default is TRUE. This property is provided to satisfy certain providers, such as Quickbooks, that require all MIME headers to be single unfolded lines regardless of length.

top
AllowHeaderQB
BOOL CkRestW_getAllowHeaderQB(HCkRestW cHandle);
void CkRestW_putAllowHeaderQB(HCkRestW cHandle, BOOL newVal);
Introduced in version 9.5.0.59

Controls whether non us-ascii HTTP request headers are automatically Q/B encoded. The default value is TRUE.

Q/B encoded headers explicitly indicate the charset and byte representation, and appear as such: =?utf-8?Q?...?= or =?utf-8?B?...?=, where the charset may be "utf-8" or any other possible charset.

If this property is set to FALSE, then no Q/B encoding is applied to any request header.

top
Authorization
void CkRestW_getAuthorization(HCkRestW cHandle, HCkString retval);
void CkRestW_putAuthorization(HCkRestW cHandle, const wchar_t *newVal);
const wchar_t *CkRestW_authorization(HCkRestW cHandle);
Introduced in version 9.5.0.58

The value of the Authorization HTTP request header (if needed).

top
ConnectFailReason
int CkRestW_getConnectFailReason(HCkRestW cHandle);
Introduced in version 9.5.0.58

If the Connect method fails, this property can be checked to determine the reason for failure.

Possible values are:

0 = success

Normal (non-SSL) sockets:
1 = empty hostname
2 = DNS lookup failed
3 = DNS timeout
4 = Aborted by application.
5 = Internal failure.
6 = Connect Timed Out
7 = Connect Rejected (or failed for some other reason)

SSL/TLS:
100 = TLS internal error.
101 = Failed to send client hello.
102 = Unexpected handshake message.
103 = Failed to read server hello.
104 = No server certificate.
105 = Unexpected TLS protocol version.
106 = Server certificate verify failed (the server certificate is expired or the cert's signature verification failed).
107 = Unacceptable TLS protocol version.
109 = Failed to read handshake messages.
110 = Failed to send client certificate handshake message.
111 = Failed to send client key exchange handshake message.
112 = Client certificate's private key not accessible.
113 = Failed to send client cert verify handshake message.
114 = Failed to send change cipher spec handshake message.
115 = Failed to send finished handshake message.
116 = Server's Finished message is invalid.

top
ConnectTimeoutMs
int CkRestW_getConnectTimeoutMs(HCkRestW cHandle);
void CkRestW_putConnectTimeoutMs(HCkRestW cHandle, int newVal);
Introduced in version 9.5.0.71

The maximum amount of time to wait for the connection to be accepted by the HTTP server.

Note: Suprisingly, this property was forgotten and not added until Chilkat v9.5.0.71.

top
DebugLogFilePath
void CkRestW_getDebugLogFilePath(HCkRestW cHandle, HCkString retval);
void CkRestW_putDebugLogFilePath(HCkRestW cHandle, const wchar_t *newVal);
const wchar_t *CkRestW_debugLogFilePath(HCkRestW cHandle);

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
HeartbeatMs
int CkRestW_getHeartbeatMs(HCkRestW cHandle);
void CkRestW_putHeartbeatMs(HCkRestW cHandle, int newVal);
Introduced in version 9.5.0.58

This property is only valid in programming environment and languages that allow for event callbacks.

Specifies the time interval in milliseconds between AbortCheck events. A value of 0 (the default) indicate that no AbortCheck events will fire. Any REST method can be aborted via the AbortCheck event.

top
Host
void CkRestW_getHost(HCkRestW cHandle, HCkString retval);
void CkRestW_putHost(HCkRestW cHandle, const wchar_t *newVal);
const wchar_t *CkRestW_host(HCkRestW cHandle);
Introduced in version 9.5.0.58

The value of the Host HTTP request header.

top
IdleTimeoutMs
int CkRestW_getIdleTimeoutMs(HCkRestW cHandle);
void CkRestW_putIdleTimeoutMs(HCkRestW cHandle, int newVal);
Introduced in version 9.5.0.58

The maximum amount of time to wait for additional incoming data when receiving, or the max time to wait to send additional data. The default value is 30000 (30 seconds). This is not an overall max timeout. Rather, it is the maximum time to wait when receiving or sending has halted.

top
LastErrorHtml
void CkRestW_getLastErrorHtml(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_lastErrorHtml(HCkRestW cHandle);

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
void CkRestW_getLastErrorText(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_lastErrorText(HCkRestW cHandle);

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
void CkRestW_getLastErrorXml(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_lastErrorXml(HCkRestW cHandle);

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
BOOL CkRestW_getLastMethodSuccess(HCkRestW cHandle);
void CkRestW_putLastMethodSuccess(HCkRestW cHandle, BOOL newVal);
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of TRUE indicates success, a value of FALSE indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = TRUE and failure = FALSE.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to TRUE. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
LastRequestHeader
void CkRestW_getLastRequestHeader(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_lastRequestHeader(HCkRestW cHandle);
Introduced in version 9.5.0.58

The full MIME header (not including the HTTP start line which contains the status code and status text), of the last request sent.

top
LastRequestStartLine
void CkRestW_getLastRequestStartLine(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_lastRequestStartLine(HCkRestW cHandle);
Introduced in version 9.5.0.58

The full start line of the last request sent. (The start line begins with the HTTP verb, such as GET, POST, etc., is followed by the URI path, and ends with the HTTP version.)

top
NumResponseHeaders
int CkRestW_getNumResponseHeaders(HCkRestW cHandle);
Introduced in version 9.5.0.58

The number of response header fields. The first response header field is at index 0.

top
PartSelector
void CkRestW_getPartSelector(HCkRestW cHandle, HCkString retval);
void CkRestW_putPartSelector(HCkRestW cHandle, const wchar_t *newVal);
const wchar_t *CkRestW_partSelector(HCkRestW cHandle);
Introduced in version 9.5.0.58

Only used for multipart requests. Selects the target MIME part for calls to AddHeader, RemoveHeader, SetMultipartBodyBinary, SetMultipartBodyString, SetMultipartBodyStream, etc. The default is an empty string and indicates the top-level header. A string value of "1" would indicate the 1st sub-part in a multipart request. A string value of "1.2" would indicate the 2nd sub-part under the 1st sub-part.

It is unlikely you'll ever encounter the need for nested multipart requests (i.e. part selectors such as "1.2") Also, most REST requests are NOT multipart, and therefore this feature is rarely used. An example of a multipart REST request would be for a Google Drive upload, where the top-level Content-Type is multipart/related, the1st sub-part contains the JSON meta-data, and the 2nd sub-part contains the file data.

top
PercentDoneOnSend
BOOL CkRestW_getPercentDoneOnSend(HCkRestW cHandle);
void CkRestW_putPercentDoneOnSend(HCkRestW cHandle, BOOL newVal);
Introduced in version 9.5.0.58

This property only applies to the FullRequest* methods, which are methods that both send an HTTP request and receive the response. (It also only applies to programming languages that support event callbacks.) It determines whether percentage completion is tracked for the sending of the HTTP request, or for the downloading the HTTP response. The default value is FALSE, which is to measure the percent completion when receiving the response.

For example: If the REST request is to download a file, then this property should remain at the default value of FALSE. If the REST request is to upload a file (using a Full* method), then set this property to TRUE. Also note if a server sends an HTTP response in the chunked encoding, it is not possible to measure percent completion because the HTTP client has no way of knowing the total size of the HTTP response.

top
ResponseHeader
void CkRestW_getResponseHeader(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_responseHeader(HCkRestW cHandle);
Introduced in version 9.5.0.58

The full response MIME header (not including the HTTP start line which contains the status code and status text).

top
ResponseStatusCode
int CkRestW_getResponseStatusCode(HCkRestW cHandle);
Introduced in version 9.5.0.58

The response status code.

top
ResponseStatusText
void CkRestW_getResponseStatusText(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_responseStatusText(HCkRestW cHandle);
Introduced in version 9.5.0.58

The status message corresponding to the response status code.

top
StreamNonChunked
BOOL CkRestW_getStreamNonChunked(HCkRestW cHandle);
void CkRestW_putStreamNonChunked(HCkRestW cHandle, BOOL newVal);
Introduced in version 9.5.0.58

If TRUE, then methods that upload data are sent non-chunked if possible. For example, if the FullRequestStream method is called where the stream is a file stream, then the size of the content is known and the HTTP request will be sent using a Content-Length header instead of using a Transfer-Encoding: chunked upload. If FALSE, then the chunked transfer encoding is used. The default value of this property is TRUE.

top
VerboseLogging
BOOL CkRestW_getVerboseLogging(HCkRestW cHandle);
void CkRestW_putVerboseLogging(HCkRestW cHandle, BOOL newVal);

If set to TRUE, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is FALSE. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
void CkRestW_getVersion(HCkRestW cHandle, HCkString retval);
const wchar_t *CkRestW_version(HCkRestW cHandle);

Version of the component/library, such as "9.5.0.63"

top

Methods

AddHeader
BOOL CkRestW_AddHeader(HCkRestW cHandle, const wchar_t *name, const wchar_t *value);
Introduced in version 9.5.0.58

Adds an HTTP request header. If the header field already exists, then it is replaced.

Returns TRUE for success, FALSE for failure.

top
AddMwsSignature
BOOL CkRestW_AddMwsSignature(HCkRestW cHandle, const wchar_t *httpVerb, const wchar_t *uriPath, const wchar_t *domain, const wchar_t *mwsSecretKey);
Introduced in version 9.5.0.66

Computes the Amazon MWS signature using the mwsSecretKey and adds the "Signature" parameter to the request. This method should be called for all Amazon Marketplace Web Service (Amazon MWS) HTTP requests. It should be called after all request parameters have been added.

Important: The Chilkat v9.5.0.75 release accidentally breaks Amazon MWS (not AWS) authentication. If you need MWS with 9.5.0.75, send email to support@chilkatsoft.com for a hotfix, or revert back to v9.5.0.73, or update to a version after 9.5.0.75.

The domain should be the domain of the request, such as one of the following:

  • mws.amazonservices.com
  • mws-eu.amazonservices.com
  • mws.amazonservices.in
  • mws.amazonservices.com.cn
  • mws.amazonservices.jp

The httpVerb should be the HTTP verb, such as "GET", "POST", etc. The uriPath is the URI path, such as "/Feeds/2009-01-01". In general, the httpVerb and uriPath should be identical to the 1st two args passed to methods such as FullRequestFormUrlEncoded.

Note: This method also automatically adds or replaces the existing Timestamp parameter to the current system date/time.

Returns TRUE for success, FALSE for failure.

top
AddPathParam
BOOL CkRestW_AddPathParam(HCkRestW cHandle, const wchar_t *name, const wchar_t *value);
Introduced in version 9.5.0.70

Adds or replaces a path parameter. A path parameter is a string that will be replaced in any uriPath string passed to a method. For example, if name is "fileId" and value is "1R_70heIyzIAu1_u0prXbYcaIiJRVkgBl", then a uriPath argument of "/drive/v3/files/fileId" will be transformed to "/drive/v3/files/1R_70heIyzIAu1_u0prXbYcaIiJRVkgBl" in a method call.

Returns TRUE for success, FALSE for failure.

top
AddQueryParam
BOOL CkRestW_AddQueryParam(HCkRestW cHandle, const wchar_t *name, const wchar_t *value);
Introduced in version 9.5.0.58

Adds a query parameter. If the query parameter already exists, then it is replaced.

Returns TRUE for success, FALSE for failure.

top
AddQueryParams
BOOL CkRestW_AddQueryParams(HCkRestW cHandle, const wchar_t *queryString);
Introduced in version 9.5.0.58

Adds the query parameters from the queryString. The queryString is a query string of the format field1=value1&field2=value2&field3=value3... where each value is URL encoded.

Returns TRUE for success, FALSE for failure.

top
AddQueryParamSb
BOOL CkRestW_AddQueryParamSb(HCkRestW cHandle, const wchar_t *name, HCkStringBuilderW value);
Introduced in version 9.5.0.62

Adds a query parameter. If the query parameter already exists, then it is replaced. The parameter value is passed in a StringBuilder object.

Returns TRUE for success, FALSE for failure.

top
ClearAllHeaders
BOOL CkRestW_ClearAllHeaders(HCkRestW cHandle);
Introduced in version 9.5.0.58

Removes all HTTP request headers.

Returns TRUE for success, FALSE for failure.

top
ClearAllParts
BOOL CkRestW_ClearAllParts(HCkRestW cHandle);
Introduced in version 9.5.0.64

Removes all sub-parts from a request. This is useful when preparing the REST object to send a new request after a multipart request has just been sent.

Returns TRUE for success, FALSE for failure.

More Information and Examples
top
ClearAllPathParams
BOOL CkRestW_ClearAllPathParams(HCkRestW cHandle);
Introduced in version 9.5.0.70

Clears all path parameters.

Returns TRUE for success, FALSE for failure.

top

Returns TRUE for success, FALSE for failure.

top
ClearResponseBodyStream
void CkRestW_ClearResponseBodyStream(HCkRestW cHandle);
Introduced in version 9.5.0.58

Clears the response body stream set by calling SetResponseBodyStream.

top
Connect
BOOL CkRestW_Connect(HCkRestW cHandle, const wchar_t *hostname, int port, BOOL tls, BOOL autoReconnect);
Introduced in version 9.5.0.58

Establishes an initial connection to a REST server. The hostname can be a domain name or an IP address. Both IPv4 and IPv6 addresses are supported. The port is the port, which is typically 80 or 443. If SSL/TLS is required, then tls should be set to TRUE. The autoReconnect indicates whether connection should automatically be established as needed for subsequent REST requests.

Note: This method is for simple connections that do not require any proxies (HTTP or SOCKS), or SSH tunneling. If a proxy, SSH tunnel, or any other advanced socket feature is required, the Chilkat Socket API can be used to establish the connection. The UseConnection method can then be called to use the pre-established socket connection.

Returns TRUE for success, FALSE for failure.

top
ConnectAsync (1)
HCkTaskW CkRestW_ConnectAsync(HCkRestW cHandle, const wchar_t *hostname, int port, BOOL tls, BOOL autoReconnect);
Introduced in version 9.5.0.58

Returns NULL on failure

top
Disconnect
BOOL CkRestW_Disconnect(HCkRestW cHandle, int maxWaitMs);
Introduced in version 9.5.0.58

Closes the connection with the HTTP server if one is open. This method can be called to ensure the connection is closed. The maxWaitMs is the maximum time in milliseconds to wait for a clean close. If the connection is through an SSH tunnel, this closes the logical channel within the SSH tunnel, and not the connection with the SSH server itself.

Returns TRUE for success, FALSE for failure.

SetResponseBodyStream
BOOL CkRestW_SetResponseBodyStream(HCkRestW cHandle, int expectedStatus, BOOL autoSetStreamCharset, HCkStreamW responseStream);
Introduced in version 9.5.0.58

Only applies to the Full* methods, such as FullRequestNoBody, FullRequestBinary, FullRequestStream, etc. When set, the response body is streamed directly to responseStream, if (and only if) the HTTP response status code equals expectedStatus.

If the response body was streamed to responseStream, then the string return value of the Full* method instead becomes "OK" for success. If an attempt was made to stream the response body but it failed, then "FAIL" is returned. If the response body was not streamed because the response status code was not equal to expectedStatus, then the returned string contains the server's error response.

If autoSetStreamCharset is TRUE, then the expectedStatus's StringCharset property will automatically get set based on the charset, if any, indicated in the response header. If the response is binary, then autoSetStreamCharset is ignored.

Starting in v9.5.0.75, the expectedStatus may be passed as a negative number to specify a range of expected (success) status codes. For example:

  • -200: Allow status codes 200 - 299
  • -210: Allow status codes 210 - 219
  • -220: Allow status codes 220 - 229

It may be a TLS connection, an unencrypted connection, through an HTTP proxy, a SOCKS proxy, or even through SSH tunnels. All of the connection related functionality is handled by the Chilkat Socket API.

The autoReconnect indicates whether connection should automatically be established as needed for subsequent REST requests.

Important: The UseConnection method is provided as a means for handling more complicated connections -- such as connections through proxies, tunnels, etc. If your application is connecting directly to the HTTP server, then simply call this class's Connect method.

Returns TRUE for success, FALSE for failure.
