Known implementations: twisted.web.server.Request

An HTTP request.

Present Since9.0
Attribute method A str giving the HTTP method that was used.
Attribute uri A str giving the full encoded URI which was requested (including query arguments).
Attribute path A str giving the encoded query path of the request URI.
Attribute args 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']}.
Attribute requestHeaders A http_headers.Headers instance giving all received HTTP request headers.
Attribute content A file-like object giving the request body. This may be a file on disk, a StringIO, or some other type. The implementation is free to decide on a per-request basis.
Attribute responseHeaders A http_headers.Headers instance holding all HTTP response headers to be sent.

method =

A str giving the HTTP method that was used.

uri =

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

path =

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

args =

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']}.

requestHeaders =

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

content =

A file-like object giving the request body. This may be a file on disk, a StringIO, or some other type. The implementation is free to decide on a per-request basis.

responseHeaders =

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

def getHeader(key): (source)

Get an HTTP request header.

ParameterskeyThe name of the header to get the value of. (type: str)
ReturnsThe value of the specified header, or None if that header was not present in the request. (type: str or None)
def getCookie(key): (source)

Get a cookie that was sent from the network.

def getAllHeaders(): (source)

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.

def getRequestHostname(): (source)

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.

Returnsthe requested hostname (type: str)
def getHost(): (source)

Get my originally requesting transport's host.

ReturnsAn IAddress.
def getClientAddress(): (source)

Return the address of the client who submitted this request.

The address may not be a network address. Callers must check its type before using it.

Returnsthe client's address. (type: an IAddress provider.)
Present Since18.4
def getClientIP(): (source)

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

This method is deprecated. See getClientAddress instead.

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

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

If no user was supplied, return the empty string.

Returnsthe HTTP user, if any (type: str)
def getPassword(): (source)

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

If no password was supplied, return the empty string.

Returnsthe HTTP password, if any (type: str)
def isSecure(): (source)

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.

ReturnsTrue if this request is secure (type: bool)
def getSession(sessionInterface=None): (source)

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

ReturnsThe Session instance identified by the session cookie in the request, or the sessionInterface component of that session if sessionInterface is specified.
def URLPath(): (source)
ReturnsA URLPath instance which identifies the URL for which this request is.
def prePathURL(): (source)
ReturnsAt any time during resource traversal, a str giving an absolute URL to the most nested resource which has yet been reached.
def rememberRootURL(): (source)

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

def getRootURL(): (source)

Get a previously-remembered URL.

def finish(): (source)

Indicate that the response to this request is complete.

def write(data): (source)

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.

def addCookie(k, v, expires=None, domain=None, path=None, max_age=None, comment=None, secure=None): (source)

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.

def setResponseCode(code, message=None): (source)

Set the HTTP response code.

def setHeader(k, v): (source)

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

ParametersnameThe name of the header for which to set the value. (type: str)
valueThe value to set for the named header. (type: str)
def redirect(url): (source)

Utility function that does a redirect.

The request should have finish() called after this.

def setLastModified(when): (source)

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.

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

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.

ParametersetagThe entity tag for the resource being returned. (type: str)
ReturnsIf I am a If-None-Match conditional request and the tag matches one in the request, I return CACHED to indicate that you should write no body. Otherwise, I return a false value.
def setHost(host, port, ssl=0): (source)

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)
