The handlers raise this exception (or derived exceptions) when they run into a problem. The following exceptions are raised as appropriate: exception urllib2.URLError If the Python installation has SSL support (i.e., if the ssl module can be imported), HTTPSHandler will also be added.īeginning in Python 2.3, a BaseHandler subclass may also change its handler_order attribute to modify its position in the handlers list. Instances of the following classes will be in front of the handlers, unless the handlers contain them, instances of them or subclasses of them: ProxyHandler (if proxy settings are detected), UnknownHandler, HTTPHandler, HTTPDefaultErrorHandler, HTTPRedirectHandler, FTPHandler, FileHandler, HTTPErrorProcessor. handlers can be either instances of BaseHandler, or subclasses of BaseHandler (in which case it must be possible to call the constructor without any parameters). Return an OpenerDirector instance, which chains the handlers in the order given.

The code does not check for a real OpenerDirector, and any class with the appropriate interface will work. Installing an opener is only necessary if you want urlopen to use that opener otherwise, simply call OpenerDirector.open() instead of urlopen().

Install an OpenerDirector instance as the default global opener. In addition, if proxy settings are detected (for example, when a *_proxy environment variable like http_proxy is set), ProxyHandler is default installed and makes sure the requests are handled through the proxy.Ĭhanged in version 2.7.9: cafile, capath, cadefault, and context were added. Note that None may be returned if no handler handles the request (though the default installed global OpenerDirector uses UnknownHandler to ensure this never happens).

getcode() - return the HTTP status code of the response.

info() - return the meta-information of the page, such as headers, in the form of an mimetools.Message instance (see Quick Reference to HTTP Headers).

geturl() - return the URL of the resource retrieved, commonly used to determine if a redirect was followed.

This function returns a file-like object with three additional methods: More information can be found in _verify_locations(). cafile should point to a single file containing a bundle of CA certificates, whereas capath should point to a directory of hashed certificate files. The optional cafile and capath parameters specify a set of trusted CA certificates for HTTPS requests. If context is specified, it must be a ssl.SSLContext instance describing the various SSL options. This actually only works for HTTP, HTTPS and FTP connections. The optional timeout parameter specifies a timeout in seconds for blocking operations like the connection attempt (if not specified, the global default timeout setting will be used).

urllib2 module sends HTTP/1.1 requests with Connection:close header included. data should be a buffer in the standard application/x-function takes a mapping or sequence of 2-tuples and returns a string in this format. Currently HTTP requests are the only ones that use data the HTTP request will be a POST instead of a GET when the data parameter is provided. Open the URL url, which can be either a string or a Request object.ĭata may be a string specifying additional data to send to the server, or None if no such data is needed. The urllib2 module defines the following functions: urllib2.urlopen(url]]]]) The Requests package is recommended for a higher-level HTTP client interface.
