Part of twisted.web.client View Source View In Hierarchy
Agent is a very
basic HTTP client. It supports HTTP and HTTPS scheme URIs
(but performs no certificate checking by default).| Parameters | pool | A HTTPConnectionPool
instance, or None, in which case a non-persistent HTTPConnectionPool
instance will be created. |
| Present Since | 9.0 | |
| Method | __init__ | Undocumented |
| Method | request | Issue a new request. |
| Instance Variable | _contextFactory | A web context factory which will be used to create SSL context objects for any SSL connections the agent needs to make. |
| Instance Variable | _connectTimeout | If not None, the timeout passed to connectTCP or
connectSSL for specifying the connection timeout. |
| Instance Variable | _bindAddress | If not None, the address passed to connectTCP or
connectSSL for specifying the local address to bind to. |
| Method | _wrapContextFactory | Create and return a normal context factory wrapped around
self._contextFactory in such a way that
self._contextFactory will have the host and port information
passed to it. |
| Method | _getEndpoint | Get an endpoint for the given host and port, using a transport selected based on scheme. |
Inherited from _AgentBase:
| Instance Variable | _reactor | The IReactorTime implementation which will be used by the
pool, and perhaps by subclasses as well. |
| Instance Variable | _pool | The HTTPConnectionPool
used to manage HTTP connections. |
| Method | _computeHostValue | Compute the string to use for the value of the Host header, based on the given scheme, host name, and port number. |
| Method | _requestWithEndpoint | Issue a new request, given the endpoint and the path sent as part of the request. |
None, the timeout passed to connectTCP or
connectSSL for specifying the connection timeout.
None, the address passed to connectTCP or
connectSSL for specifying the local address to bind to.
self._contextFactory in such a way that
self._contextFactory will have the host and port information
passed to it.| Parameters | host | A str giving the hostname which will be connected to in order
to issue a request. |
| port | An int giving the port number the connection will be on. | |
| Returns | A context factory suitable to be passed to reactor.connectSSL. | |
| Parameters | scheme | A string like 'http' or 'https' (the only two
supported values) to use to determine how to establish the connection. |
| host | A str giving the hostname which will be connected to in order
to issue a request. | |
| port | An int giving the port number the connection will be on. | |
| Returns | An endpoint which can be used to connect to given address. | |
| Parameters | method | The request method to send. (type: str) |
| uri | The request URI send. (type: str) | |
| headers | The request headers to send. If no Host header is included, one
will be added based on the request URI. (type: Headers) | |
| bodyProducer | An object which will produce the request body or, if the request body is to
be empty, None. (type: IBodyProducer
provider) | |
| Returns | A Deferred
which fires with the result of the request (a twisted.web.iweb.IResponse
provider), or fails if there is a problem setting up a connection over
which to issue the request. It may also fail with SchemeNotSupported
if the scheme of the given URI is not supported. (type: Deferred) | |
