Detailed Description

This wrapper class will call out to curl (if available) or fallback to regular PHP if necessary for handling internal HTTP requests.

Renamed from HttpRequest to MWHttpRequest to avoid conflict with PHP's HTTP extension.

Definition at line 33 of file MWHttpRequest.php.

string$urlUrl to use. If protocol-relative, will be expanded to an http:// URL
array$options(optional) extra params to pass (see Http::request())
string$callerThe method making this request, for profiling

MWHttpRequest::execute ( )

Take care of whatever is necessary to perform the URI request.

Returns

static MWHttpRequest::factory (   $url,
  $options = null,
  $caller = __METHOD__

static

Generate a new request object.

MWHttpRequest::getContent ( )

Get the body, or content, of the response to the request.

Returns
string

Definition at line 206 of file MWHttpRequest.php.

References $content.

MWHttpRequest::getCookieJar ( )

Returns the cookie jar in use.

Returns
CookieJar

Definition at line 512 of file MWHttpRequest.php.

References $cookieJar, and parseHeader().

MWHttpRequest::getFinalUrl ( )

Returns the final URL after all redirections.

Relative values of the "Location" header are incorrect as stated in RFC, however they do happen and modern browsers support them. This function loops backwards through all locations in order to build the proper absolute URI - Marooned at wikia-inc.com

Note that the multiple Location: headers are an artifact of CURL – they shouldn't actually get returned this way. Rewrite this when bug 29232 is taken care of (high-level redirect handling rewrite).

Returns
string

MWHttpRequest::getHeaderList ( )

Get an array of the headers.

Returns
array

MWHttpRequest::getResponseHeader (   $header)

Returns the value of the given response header.

Parameters
string$header
Returns
string|null

Definition at line 485 of file MWHttpRequest.php.

References $header, and parseHeader().

Referenced by PhpHttpRequest\execute().

MWHttpRequest::getResponseHeaders ( )

Returns an associative array of response headers after the request has been executed.

Because some headers (e.g. Set-Cookie) can appear more than once the, each value of the associative array is an array of the values given.

Returns
array

References $respHeaders, and parseHeader().

Referenced by getFinalUrl().

MWHttpRequest::getStatus ( )

Get the integer value of the HTTP status code (e.g.

200 for "200 Ok") (see RFC2616, section 10, http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html for a list of status codes.)

Returns
int

References $respStatus, and parseHeader().

static MWHttpRequest::isLocalURL (   $url)
staticprivate

Check if the URL can be served by localhost.

Parameters
string$urlFull url to check
Returns
bool

Definition at line 246 of file MWHttpRequest.php.

References $matches, $url, $wgCommandLineMode, and global.

MWHttpRequest::isRedirect ( )

Returns true if the last status code was a redirect.

Returns
bool

References $status, and parseHeader().

Referenced by PhpHttpRequest\execute().

MWHttpRequest::parseCookies ( )
protected

References $url, as, and getFinalUrl().

Referenced by parseHeader().

MWHttpRequest::parseHeader ( )
protected

Parses the headers, including the HTTP status code and any Set-Cookie headers.

This function expects the headers to be found in an array in the member variable headerList.

Take care of setting up the proxy (do nothing if "noProxy" is set)

Returns
void

Definition at line 225 of file MWHttpRequest.php.

References Http\getProxy().

Referenced by execute().

MWHttpRequest::read (   $fh,
  $content 
)

A generic callback to read the body of the response from a remote server.

Parameters
resource$fh
string$content
Returns
int

Definition at line 354 of file MWHttpRequest.php.

References $content, and content.

MWHttpRequest::setCallback (   $callback)

Set a read callback to accept data read from the HTTP request.

By default, data is appended to an internal buffer which can be retrieved through $req->getContent().

To handle data as it comes in – especially for large files that would not fit in memory – you can instead set your own callback, in the form function($resource, $buffer) where the first parameter is the low-level resource being read (implementation specific), and the second parameter is the data buffer.

You MUST return the number of bytes handled in the buffer; if fewer bytes are reported handled than were passed to you, the HTTP fetch will be aborted.

Parameters
callable$callback
Exceptions
MWException

Definition at line 339 of file MWHttpRequest.php.

References $callback.

Referenced by execute().

MWHttpRequest::setCookie (   $name,
  $value = null,
  $attr = null 
)

Sets a cookie.

Used before a request to set up any individual cookies. Used internally after a request to parse the Set-Cookie headers.

Cookie::set
Parameters
string$name
mixed$value
array$attr

Definition at line 529 of file MWHttpRequest.php.

References $name, $value, and CookieJar\setCookie().

MWHttpRequest::setCookieJar (   $jar)

Tells the MWHttpRequest object to use this pre-loaded CookieJar.

Parameters
CookieJar$jar

Definition at line 503 of file MWHttpRequest.php.

MWHttpRequest::setData (   $args)

Set the parameters of the request.

Parameters
