CkHttpResponse C++ Reference Documentation

CkHttpResponse

Represents a complete HTTP response.

Properties

void get_Body(CkByteData &byteData);

The response body returned as a byte array.

void get_BodyQP(CkString &str);
const char *bodyQP(void);

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

void get_BodyStr(CkString &str);
const char *bodyStr(void);

The response body returned as a string.

void get_Charset(CkString &str);
const char *charset(void);

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

unsigned long get_ContentLength(void);

The content length of the response, in bytes.

__int64 get_ContentLength64(void);

The content length of the response, in number of bytes, returned as a 64-bit integer.

SYSTEMTIME & get_Date(void);

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

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

void get_DateStr(CkString &str);
const char *dateStr(void);

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

void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *ansiOrUtf8Str);

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.

void get_Domain(CkString &str);
const char *domain(void);

The domain of the HTTP server that created this response.

void get_FinalRedirectUrl(CkString &str);
const char *finalRedirectUrl(void);

Introduced in version 9.5.0.49

Returns the redirect URL for 301/302 responses.

void get_FullMime(CkString &str);
const char *fullMime(void);

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

void get_Header(CkString &str);
const char *header(void);

The full text of the response header.

void get_LastErrorHtml(CkString &str);
const char *lastErrorHtml(void);

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.

void get_LastErrorText(CkString &str);
const char *lastErrorText(void);

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

void get_LastErrorXml(CkString &str);
const char *lastErrorXml(void);

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.

bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(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.

int get_NumCookies(void);

The number of cookies included in the response.

int get_NumHeaderFields(void);

The number of response header fields.

int get_StatusCode(void);

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.

void get_StatusLine(CkString &str);
const char *statusLine(void);

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

void get_StatusText(CkString &str);
const char *statusText(void);

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".

bool get_Utf8(void);
void put_Utf8(bool newVal);

When set to true, all "const char *" arguments are interpreted as utf-8 strings. If set to false (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to true, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to false, all "const char *" return values are ANSI strings.

bool get_VerboseLogging(void);
void put_VerboseLogging(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.

void get_Version(CkString &str);
const char *version(void);

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

bool LoadTaskResult(CkTask &task);

Introduced in version 9.5.0.52

bool SaveBodyBinary(const char *path);

Saves the body of the HTTP response to a file.

Returns true for success, false for failure.

bool SaveBodyText(bool bCrlf, const char *path);

Saves the HTTP response body to a file. This method provides control over CRLF vs bare-LF line-endings. If bCrlf is true, then line endings are automatically converted to CRLF if necessary. If bCrlf is false, 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 true for success, false for failure.

bool SaveLastError(const char *path);

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

Returns true for success, false for failure.

bool UrlEncParamValue(const char *encodedParamString, const char *paramName, CkString &outStr);
const char *urlEncParamValue(const char *encodedParamString, const char *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 true for success, false for failure.
