Properties

Body
void get_Body(CkByteData &byteData);

The response body returned as a byte array.

top
BodyQP
void get_BodyQP(CkString &str);
const wchar_t *bodyQP(void);

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

top
BodyStr
void get_BodyStr(CkString &str);
const wchar_t *bodyStr(void);

The response body returned as a string.

top
Charset
void get_Charset(CkString &str);
const wchar_t *charset(void);

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

top
ContentLength
unsigned long get_ContentLength(void);

The content length of the response, in bytes.

top
ContentLength64
__int64 get_ContentLength64(void);

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

top
DateStr
void get_DateStr(CkString &str);
const wchar_t *dateStr(void);

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

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const wchar_t *debugLogFilePath(void);
void put_DebugLogFilePath(const wchar_t *str);

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
Domain
void get_Domain(CkString &str);
const wchar_t *domain(void);

The domain of the HTTP server that created this response.

top
FinalRedirectUrl
void get_FinalRedirectUrl(CkString &str);
const wchar_t *finalRedirectUrl(void);
Introduced in version 9.5.0.49

Returns the redirect URL for 301/302 responses.

top
FullMime
void get_FullMime(CkString &str);
const wchar_t *fullMime(void);

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

top
Header
void get_Header(CkString &str);
const wchar_t *header(void);

The full text of the response header.

top
LastErrorHtml
void get_LastErrorHtml(CkString &str);
const wchar_t *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.

top
LastErrorText
void get_LastErrorText(CkString &str);
const wchar_t *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.

top
LastErrorXml
void get_LastErrorXml(CkString &str);
const wchar_t *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.

top
LastMethodSuccess
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

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
NumCookies
int get_NumCookies(void);

The number of cookies included in the response.

top
NumHeaderFields
int get_NumHeaderFields(void);

The number of response header fields.

top
StatusCode
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.

top
StatusLine
void get_StatusLine(CkString &str);
const wchar_t *statusLine(void);

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

top
StatusText
void get_StatusText(CkString &str);
const wchar_t *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".

top
UncommonOptions
void get_UncommonOptions(CkString &str);
const wchar_t *uncommonOptions(void);
void put_UncommonOptions(const wchar_t *str);
Introduced in version 9.5.0.89

This is a catch-all property to be used for uncommon needs. Can be set to a list of the following comma separated keywords:

  • "TakeResponseBody" - Introduced in v9.5.0.89. The GetBody* methods will transfer the body to the target object instead of copying the contents. This can be useful if the response body is extremely large because it will reduce the overall memory requirement.

top
VerboseLogging
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.

top
Version
void get_Version(CkString &str);
const wchar_t *version(void);

Version of the component/library, such as "9.5.0.94"
