CkoHttpResponse Objective-C Reference Documentation

CkoHttpResponse

Represents a complete HTTP response.

Properties

@property (nonatomic, readonly, copy) NSData *Body;

The response body returned as a byte array.

@property (nonatomic, readonly, copy) NSString *BodyQP;

The same as the Body property, but returned as a quoted-printable encoded string.

@property (nonatomic, readonly, copy) NSString *BodyStr;

The response body returned as a string.

@property (nonatomic, readonly, copy) NSString *Charset;

The response charset, such as "iso-8859-1", if applicable. Obviously, responses for GIF and JPG files will not have a charset.

@property (nonatomic, readonly, copy) NSNumber *ContentLength;

The content length of the response, in bytes.

@property (nonatomic, readonly, copy) NSDate *Date;

This property is deprecated. It will be removed in a future version.

The Date response header field, returned in a date/time data type.

@property (nonatomic, readonly, copy) NSString *DateStr;

Returns the content of the Date response header field in RFC822 date/time string format.

@property (nonatomic, copy) NSString *DebugLogFilePath;

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.

@property (nonatomic, readonly, copy) NSString *Domain;

The domain of the HTTP server that created this response.

@property (nonatomic, readonly, copy) NSString *FinalRedirectUrl;

Introduced in version 9.5.0.49

Returns the redirect URL for 301/302 responses.

@property (nonatomic, readonly, copy) NSString *FullMime;

Returns the full MIME (header + body) of the HTTP response.

@property (nonatomic, readonly, copy) NSString *Header;

The full text of the response header.

@property (nonatomic, readonly, copy) NSString *LastErrorHtml;

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.

@property (nonatomic, readonly, copy) NSString *LastErrorText;

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.

Concept of LastErrorText

LastErrorText Standard Information

@property (nonatomic, readonly, copy) NSString *LastErrorXml;

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.

@property (nonatomic) BOOL LastMethodSuccess;

Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of YES indicates success, a value of NO 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 = YES and failure = NO.
  • 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 YES. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

@property (nonatomic, readonly, copy) NSNumber *NumCookies;

The number of cookies included in the response.

@property (nonatomic, readonly, copy) NSNumber *NumHeaderFields;

The number of response header fields.

@property (nonatomic, readonly, copy) NSNumber *StatusCode;

The status code (as an integer) from the first line of an HTTP response. If the StatusLine = "HTTP/1.0 200 OK", the response status code returned is 200.

@property (nonatomic, readonly, copy) NSString *StatusLine;

The first line of an HTTP response, such as "HTTP/1.0 200 OK".

@property (nonatomic, readonly, copy) NSString *StatusText;

Introduced in version 9.5.0.49

The text that follows the status code in the 1st line of the HTTP response. For example, i the first line of an HTTP response is "HTTP/1.0 200 OK", then this property contains "OK".

@property (nonatomic) BOOL VerboseLogging;

If set to YES, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is NO. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

@property (nonatomic, readonly, copy) NSString *Version;

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

Methods

- (BOOL)GetBodyBd:(CkoBinData *)binData;

Introduced in version 9.5.0.64

Copies the response body to a BinData object.

Returns YES for success, NO for failure.

- (BOOL)GetBodySb:(CkoStringBuilder *)sb;

Introduced in version 9.5.0.64

Copies the response body to a Chilkat StringBuilder object.

Returns YES for success, NO for failure.

- (NSString *)GetCookieDomain:(NSNumber *)index;

Returns the domain of the Nth cookie in the response. Indexing begins at 0. The number of response cookies is specified in the NumCookies property.

Returns nil on failure

- (NSDate *)GetCookieExpires:(NSNumber *)index;

This method is deprecated. It will be removed in a future version.

Returns the expiration date/time of the Nth cookie in the response. Indexing begins at 0. The number of response cookies is specified in the NumCookies property.

- (NSString *)GetCookieExpiresStr:(NSNumber *)index;

Returns the expiration date/time of the Nth cookie in the response. Indexing begins at 0. The number of response cookies is specified in the NumCookies property.

Returns nil on failure

- (NSString *)GetCookieName:(NSNumber *)index;

Returns nil on failure

- (NSString *)GetHeaderFieldAttr:(NSString *)fieldName
    attrName:(NSString *)attrName;

Returns a response header field attribute. As an example, the response charset is simply the GetHeaderFieldAttr("content-type","charset")

Returns nil on failure

- (NSString *)GetHeaderName:(NSNumber *)index;

Returns nil on failure

- (BOOL)LoadTaskResult:(CkoTask *)task;

Introduced in version 9.5.0.52

Loads the HTTP response from a completed asynchronous task. A failed return value indicates that no HTTP response was received in the HTTP asynchronous method call (i.e. the asynchronous HTTP request failed in such a way that no response was received).

Returns YES for success, NO for failure.

Getting the HTTP Response after an Asynchronous HTTP Request Completes

- (BOOL)SaveBodyBinary:(NSString *)path;

Saves the body of the HTTP response to a file.

Returns YES for success, NO for failure.

- (BOOL)SaveBodyText:(BOOL)bCrlf
    path:(NSString *)path;

Saves the HTTP response body to a file. This method provides control over CRLF vs bare-LF line-endings. If bCrlf is YES, then line endings are automatically converted to CRLF if necessary. If bCrlf is NO, then line-endings are automatically converted to bare-LF's (Unix style) if necessary.

To save the HTTP response body exactly as-is (with no line-ending manipulation), then call SaveBodyBinary.

Returns YES for success, NO for failure.

- (BOOL)SaveLastError:(NSString *)path;

Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.

Returns YES for success, NO for failure.

- (NSString *)UrlEncParamValue:(NSString *)encodedParams
    paramName:(NSString *)paramName;

Convenience method for parsing a param's value out of a URL-encoded param string. For example, if a caller passes the following string in encodedParamString:

oauth_token=ABC&oauth_token_secret=123&oauth_callback_confirmed=true
and "oauth_token_secret" in paramName, then the return value would be "123".

Returns nil on failure
