(View In Hierarchy)
Implements interfaces: twisted.web.iweb.IAgent
Agent is a very
basic HTTP client. It supports HTTP and HTTPS scheme
URIs.
| Present Since | 9.0 | |
| Method | __init__ | Create an Agent. |
| Class Method | usingEndpointFactory | Create a new Agent that will use
the endpoint factory to figure out how to connect to the server. |
| Method | request | Issue a request to the server indicated by the given
uri. |
| Instance Variable | _pool | An HTTPConnectionPool
instance. |
| Instance Variable | _endpointFactory | The IAgentEndpointFactory
which will be used to create endpoints for outgoing connections. |
| Method | _init | Initialize a new Agent. |
| Method | _getEndpoint | Get an endpoint for the given URI, using
self._endpointFactory. |
Inherited from _AgentBase:
| Instance Variable | _reactor | The IReactorTime implementation which will be used by the
pool, and perhaps by subclasses as well. |
| 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. |
IAgentEndpointFactory
which will be used to create endpoints for outgoing connections.
Create an Agent.
| Parameters | reactor | A provider of twisted.internet.interfaces.IReactorTCP
and twisted.internet.interfaces.IReactorSSL
for this Agent to
place outgoing connections. (type: twisted.internet.interfaces.IReactorTCP
and twisted.internet.interfaces.IReactorSSL) |
| contextFactory | A factory for TLS contexts, to control the verification parameters of
OpenSSL. The default is to use a BrowserLikePolicyForHTTPS,
so unless you have special requirements you can leave this as-is. (type: IPolicyForHTTPS.) | |
| connectTimeout | The amount of time that this Agent will wait for
the peer to accept a connection. (type: float) | |
| bindAddress | The local address for client sockets to bind to. (type: bytes) | |
| pool | An HTTPConnectionPool
instance, or None, in which case a non-persistent HTTPConnectionPool
instance will be created. (type: HTTPConnectionPool) |
Create a new Agent that will use
the endpoint factory to figure out how to connect to the server.
| Parameters | reactor | A provider of twisted.internet.interfaces.IReactorTime. |
| endpointFactory | Used to construct endpoints which the HTTP client will connect with. (type: an IAgentEndpointFactory
provider.) | |
| pool | An HTTPConnectionPool
instance, or None, in which case a non-persistent HTTPConnectionPool
instance will be created. (type: HTTPConnectionPool) | |
| Returns | A new Agent. | |
Initialize a new Agent.
| Parameters | reactor | A provider of relevant reactor interfaces, at a minimum twisted.internet.interfaces.IReactorTime. |
| endpointFactory | Used to construct endpoints which the HTTP client will connect with. (type: an IAgentEndpointFactory
provider.) | |
| pool | An HTTPConnectionPool
instance, or None, in which case a non-persistent HTTPConnectionPool
instance will be created. (type: HTTPConnectionPool) | |
| Returns | A new Agent. | |
Get an endpoint for the given URI, using
self._endpointFactory.
| Parameters | uri | The URI of the request. (type: URI) |
| Returns | An endpoint which can be used to connect to given address. | |
Issue a request to the server indicated by the given
uri.
An existing connection from the connection pool may be used or a new one may be created.
HTTP and HTTPS schemes are supported in
uri.
