t.w.i.IRequest(Interface) : interface documentation

A str giving the HTTP method that was used.

A str giving the full encoded URI which was requested (including query arguments).

A str giving the encoded query path of the request URI.

A mapping of decoded query argument names as str to corresponding query argument values as lists of str. For example, for a URI with 'foo=bar&foo=baz&quux=spam' for its query part, args will be {'foo': ['bar', 'baz'], 'quux': ['spam']}.

Backwards-compatibility access to requestHeaders. Use requestHeaders instead. received_headers behaves mostly like a dict and does not provide access to all header values.

A http_headers.Headers instance giving all received HTTP request headers.

Backwards-compatibility access to responseHeaders. UseresponseHeaders instead. headers behaves mostly like a dict and does not provide access to all header values nor does it allow multiple values for one header to be set.

A http_headers.Headers instance holding all HTTP response headers to be sent.

Get an HTTP request header.

Parameters	key	The name of the header to get the value of. (type: str )
Returns	The value of the specified header, or None if that header was not present in the request. (type: str or NoneType )

Get a cookie that was sent from the network.

Return dictionary mapping the names of all received headers to the last value received for each.

Since this method does not return all header information, requestHeaders.getAllRawHeaders() may be preferred.

Get the hostname that the user passed in to the request.

This will either use the Host: header (if it is available) or the host we are listening on if the header is unavailable.

Returns

the requested hostname (type: str )

Get my originally requesting transport's host.

Returns

An IAddress.

Return the IP address of the client who submitted this request.

Returns

the client IP address or None if the request was submitted over a transport where IP addresses do not make sense. (type: str or NoneType )

Return the hostname of the IP address of the client who submitted this request, if possible.

This method is deprecated. See getClientIP instead.

Returns

The canonical hostname of the client, as determined by performing a name lookup on the IP address of the client. (type: NoneType or str )

Return the HTTP user sent with this request, if any.

If no user was supplied, return the empty string.

Returns

the HTTP user, if any (type: str )

Return the HTTP password sent with this request, if any.

If no password was supplied, return the empty string.

Returns

the HTTP password, if any (type: str )

Return True if this request is using a secure transport.

Normally this method returns True if this request's HTTPChannel instance is using a transport that implements ISSLTransport.

This will also return True if setHost() has been called with ssl=True.

Returns

True if this request is secure (type: bool )

Look up the session associated with this request or create a new one if there is not one.

Returns

The Session instance identified by the session cookie in the request, or the sessionInterface component of that session if sessionInterface is specified.

Remember the currently-processed part of the URL for later recalling.

Get a previously-remembered URL.

Indicate that the response to this request is complete.

Write some data to the body of the response to this request. Response headers are written the first time this method is called, after which new response headers may not be added.

Set an outgoing HTTP cookie.

In general, you should consider using sessions instead of cookies, see twisted.web.server.Request.getSession and the twisted.web.server.Session class for details.

Set the HTTP response code.

Set an HTTP response header. Overrides any previously set values for this header.

Parameters	name	The name of the header for which to set the value. (type: str )
	value	The value to set for the named header. (type: str )

Utility function that does a redirect.

The request should have finish() called after this.

Set the Last-Modified time for the response to this request.

If I am called more than once, I ignore attempts to set Last-Modified earlier, only replacing the Last-Modified time if it is to a later value.

If I am a conditional request, I may modify my response code to NOT_MODIFIED if appropriate for the time given.

Parameters	when	The last time the resource being returned was modified, in seconds since the epoch. (type: int, long or float )
Returns	If I am a If-Modified-Since conditional request and the time given is not newer than the condition, I return http.CACHED to indicate that you should write no body. Otherwise, I return a false value.

Set an entity tag for the outgoing response.

That's "entity tag" as in the HTTP/1.1 ETag header, "used for comparing two or more entities from the same requested resource."

If I am a conditional request, I may modify my response code to NOT_MODIFIED or PRECONDITION_FAILED, if appropriate for the tag given.

Parameters	etag	The entity tag for the resource being returned. (type: str )
Returns	If I am a If-None-Match conditional request and the tag matches one in the request, I return http.CACHED to indicate that you should write no body. Otherwise, I return a false value.

Change the host and port the request thinks it's using.

This method is useful for working with reverse HTTP proxies (e.g. both Squid and Apache's mod_proxy can do this), when the address the HTTP client is using is different than the one we're listening on.

For example, Apache may be listening on https://www.example.com, and then forwarding requests to http://localhost:8080, but we don't want HTML produced by Twisted to say 'http://localhost:8080', they should say 'https://www.example.com', so we do:

  request.setHost('www.example.com', 443, ssl=1)
