HttpResponse Objective-C Reference Documentation

CkoHttpResponse

Current Version: 10.1.2

Represents a complete HTTP response.

Object Creation

CkoHttpResponse *obj = [[CkoHttpResponse alloc] init];

Properties

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

The response body returned as a byte array.

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

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

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

The response body returned as a string.

top
Charset
@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.

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

The content length of the response, in bytes.

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

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

top
DebugLogFilePath
@property (nonatomic, copy) NSString *DebugLogFilePath;

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.

More Information and Examples

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

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

The full text of the response header.

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

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.

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

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.

top
LastErrorXml
@property (nonatomic, readonly, copy) NSString *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.

top
LastMethodSuccess
@property (nonatomic) BOOL LastMethodSuccess;

Indicates the success or failure of the most recent method call: YES means success, NO 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.

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

The number of cookies included in the response.

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

The number of response header fields.

top
StatusCode
@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.

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

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

top
StatusText
@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".

top
UncommonOptions
@property (nonatomic, copy) NSString *UncommonOptions;
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
@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.

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

Version of the component/library, such as "10.1.0"
