HttpResponse Lianja Reference Documentation

HttpResponse

Current Version: 9.5.0.75

Represents a complete HTTP response.

Object Creation

loObject = createobject("CkHttpResponse")

Properties

BodyQP
BodyQP As Character (read-only)

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

top
BodyStr
BodyStr As Character (read-only)

The response body returned as a string.

top
Charset
Charset As Character (read-only)

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

top
ContentLength
ContentLength As Numeric (read-only)

The content length of the response, in bytes.

top
DateStr
DateStr As Character (read-only)

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

top
DebugLogFilePath
DebugLogFilePath As Character

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
Domain As Character (read-only)

The domain of the HTTP server that created this response.

top
FinalRedirectUrl
FinalRedirectUrl As Character (read-only)
Introduced in version 9.5.0.49

Returns the redirect URL for 301/302 responses.

top
FullMime
FullMime As Character (read-only)

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

top
Header
Header As Character (read-only)

The full text of the response header.

top
LastErrorHtml
LastErrorHtml As Character (read-only)

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
LastErrorText As Character (read-only)

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
LastErrorXml As Character (read-only)

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
LastMethodSuccess As Boolean
Introduced in version 9.5.0.52

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

top
NumCookies
NumCookies As Numeric (read-only)

The number of cookies included in the response.

top
NumHeaderFields
NumHeaderFields As Numeric (read-only)

The number of response header fields.

top
StatusCode
StatusCode As Numeric (read-only)

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
StatusLine As Character (read-only)

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

top
StatusText
StatusText As Character (read-only)
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
VerboseLogging
VerboseLogging As Boolean

If set to .T., then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is .F.. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
Version As Character (read-only)

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

top

Returns the value of a response header field accessed by field name.

Returns .F. on failure

top
GetHeaderFieldAttr
GetHeaderFieldAttr(fieldName As Character, attrName As Character) As Character

top
LoadTaskResult
LoadTaskResult(task As CkTask) As Boolean
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).

top
SaveBodyBinary
SaveBodyBinary(path As Character) As Boolean

Saves the body of the HTTP response to a file.

Returns .T. for success, .F. for failure.

top
SaveBodyText
SaveBodyText(bCrlf As Boolean, path As Character) As Boolean

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

top

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

Returns .T. for success, .F. for failure.

top
UrlEncParamValue
UrlEncParamValue(encodedParamString As Character, paramName As Character) As Character

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 .F. on failure
