                            HttpClient

An HTTP client. A client maintains a pool of connections to a specific host, at a specific port. The HTTP connections can act as pipelines for HTTP requests. It is used as a factory for HttpClientRequest instances which encapsulate the actual HTTP requests. It is also used as a factory for HTML5 WebSocket websockets.

Method Details | [hide private]

### __init__(self, **kwargs) (Constructor) | source code
Overrides: object.__init__ (inherited documentation)

### exception_handler(self, handler) | source code
Set the exception handler. Keyword arguments: Parameters: `handler` - function to be used as the handler

### set_max_pool_size(self, val) | source code
Set the maximum pool size. The client will maintain up to this number of HTTP connections in an internal pool Keyword arguments: Parameters: `val` - The maximum number of connections (default to 1).

### set_keep_alive(self, val) | source code
If val is true then, after the request has ended the connection will be returned to the pool where it can be used by another request. In this manner, many HTTP requests can be pipe-lined over an HTTP connection. Keep alive connections will not be closed until the close method is invoked. If val is false then a new connection will be created for each request and it won't ever go in the pool, the connection will closed after the response has been received. Even with no keep alive, the client will not allow more than max_pool_size connections to be created at any one time. Keyword arguments: Parameters: `val` - The value to use for keep_alive

### set_trust_all(self, val) | source code
Should the client trust ALL server certificates? Keyword arguments: Parameters: `val` - If val is set to true then the client will trust ALL server certificates and will not attempt to authenticate them against it's local client trust store. The default value is false. Use this method with caution!

### set_port(self, val) | source code
Set the port that the client will attempt to connect to on the server on. The default value is 80 Keyword arguments: Parameters: `val` - The port value.

### set_host(self, val) | source code
Set the host name or ip address that the client will attempt to connect to on the server on. Keyword arguments: Parameters: `val` - The host name or ip address to connect to.

### connect_web_socket(self, uri, handler) | source code
Attempt to connect an HTML5 websocket to the specified URI. The connect is done asynchronously and the handler is called with a WebSocket on success. Keyword arguments: Parameters: `uri` - A relative URI where to connect the websocket on the host, e.g. /some/path `handler` - The handler to be called with the WebSocket

### get_now(self, uri, handler, **headers) | source code
This is a quick version of the get method where you do not want to do anything with the request before sing. With this method the request is immediately sent. When an HTTP response is received from the server the handler is called passing in the response. Keyword arguments: Parameters: `uri` - A relative URI where to perform the GET on the server. `handler` - The handler to be called with the HttpClientResponse `headers` - A dictionary of headers to pass with the request.

### options(self, uri, handler) | source code
This method returns an HttpClientRequest instance which represents an HTTP OPTIONS request with the specified uri. When an HTTP response is received from the server the handler is called passing in the response. Keyword arguments: Parameters: `uri` - A relative URI where to perform the OPTIONS on the server. `handler` - The handler to be called with the HttpClientResponse

### get(self, uri, handler) | source code
This method returns an HttpClientRequest instance which represents an HTTP GET request with the specified uri. When an HTTP response is received from the server the handler is called passing in the response.
