HttpResponse Unicode C++ Reference Documentation
CkHttpResponseW
Current Version: 10.1.2
Represents a complete HTTP response.
Object Creation
// Local variable on the stack CkHttpResponseW obj; // Dynamically allocate/delete CkHttpResponseW *pObj = new CkHttpResponseW(); // ... delete pObj;
Properties
Body
The response body returned as a byte array.
topBodyQP
The same as the Body property, but returned as a quoted-printable encoded string.
topBodyStr
The response body returned as a string.
topCharset
The response charset, such as "iso-8859-1", if applicable. Obviously, responses for GIF and JPG files will not have a charset.
topContentLength
The content length of the response, in bytes.
topContentLength64
The content length of the response, in number of bytes, returned as a 64-bit integer.
topDateStr
Returns the content of the Date response header field in RFC822 date/time string format.
topDebugLogFilePath
const wchar_t *debugLogFilePath(void);
void put_DebugLogFilePath(const wchar_t *str);
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
Domain
The domain of the HTTP server that created this response.
topFinalRedirectUrl
Returns the redirect URL for 301/302 responses.
topFullMime
Header
The full text of the response header.
topLastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
void put_LastMethodSuccess(bool newVal);
Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
topNumCookies
The number of cookies included in the response.
topNumHeaderFields
The number of response header fields.
topStatusCode
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.
topStatusLine
The first line of an HTTP response, such as "HTTP/1.0 200 OK".
topStatusText
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".
topUncommonOptions
const wchar_t *uncommonOptions(void);
void put_UncommonOptions(const wchar_t *str);
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.
VerboseLogging
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.

Methods
GetBodyBd
Copies the response body to a BinData object.
Returns true for success, false for failure.
GetBodyJarr
Loads the JSON array response body into a JsonArray This method should only be called when it is known that the response body contains a JSON array (beginning with a square bracket '[' and ending with a square bracket ']')
Returns true for success, false for failure.
GetBodyJson
Loads the JSON response body into a JsonObject. This method should only be called when it is known that the response body contains JSON (beginning with a curly brace '{' and ending with a curly brace '}')
Returns true for success, false for failure.
GetBodySb
Copies the response body to a Chilkat StringBuilder object.
Returns true for success, false for failure.
topGetBodyXml
Loads the XML response body into an XML object. This method should only be called when it is known that the response body contains XML.
Returns true for success, false for failure.
GetCookieDomain
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 true for success, false for failure.
topGetCookieExpiresStr
const wchar_t *getCookieExpiresStr(int 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 true for success, false for failure.
topGetCookieName
Returns the name of the Nth cookie returned in the response. Indexing begins at 0. The number of response cookies is specified in the NumCookies property.
Returns true for success, false for failure.
topGetCookiePath
Returns the path of the Nth cookie returned in the response. Indexing begins at 0. The number of response cookies is specified in the NumCookies property.
Returns true for success, false for failure.
topGetCookieValue
Returns the value of the Nth cookie returned in the response. Indexing begins at 0. The number of response cookies is specified in the NumCookies property.
Returns true for success, false for failure.
topGetHeaderField
const wchar_t *getHeaderField(const wchar_t *fieldName);
Returns the value of a response header field accessed by field name.
Returns true for success, false for failure.
topGetHeaderFieldAttr
const wchar_t *getHeaderFieldAttr(const wchar_t *fieldName, const wchar_t *attrName);
Returns a response header field attribute. As an example, the response charset is simply the GetHeaderFieldAttr("content-type","charset")
Returns true for success, false for failure.
topGetHeaderName
Gets the name of the Nth response header field. Indexing begins at 0. The number of response headers is specified by the NumHeaderFields property.
Returns true for success, false for failure.
topGetHeaderValue
Gets the value of the Nth response header field. Indexing begins at 0. The number of response headers is specified by the NumHeaderFields property.
Returns true for success, false for failure.
topLoadTaskResult
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 true for success, false for failure.
SaveBodyBinary
Saves the body of the HTTP response to a file.
Returns true for success, false for failure.
SaveBodyText
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.
topUrlEncParamValue
const wchar_t *urlEncParamValue(const wchar_t *encodedParamString, const wchar_t *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=trueand "oauth_token_secret" in paramName, then the return value would be "123".
Returns true for success, false for failure.
