HTTP context options

HTTP context options — HTTP context option listing

Beschreibung

Context options for http:// and https:// transports.

Optionen

method string

GET, POST, or any other HTTP method supported by the remote server.

Defaults to GET.

header string

Additional headers to be sent during request. Values in this option will override other values (such as User-agent:, Host:, and Authentication:).

user_agent string

Value to send with User-Agent: header. This value will only be used if user-agent is not specified in the header context option above.

By default the user_agent php.ini setting is used.

content string

Additional data to be sent after the headers. Typically used with POST or PUT requests.

proxy string

URI specifying address of proxy server. (e.g. tcp://proxy.example.com:5100).

request_fulluri boolean

When set to TRUE, the entire URI will be used when constructing the request. (i.e. GET http://www.example.com/path/to/file.html HTTP/1.0). While this is a non-standard request format, some proxy servers require it.

Defaults to FALSE.

max_redirects integer

The max number of redirects to follow. Value 1 or less means that no redirects are followed.

Defaults to 20.

protocol_version float

HTTP protocol version.

Defaults to 1.0.

timeout float

Read timeout in seconds, specified by a float (e.g. 10.5).

By default the default_socket_timeout php.ini setting is used.

ignore_errors boolean

Fetch the content even on failure status codes.

Defaults to FALSE

If you use the proxy server and encounter an error "fopen(http://example.com): failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request" note that in many situations you need also set the parameter "request_fulluri" to "true" in your stream options. Without this option the php script sends the empty request to the server as "GET / HTTP/0.0" and the proxy server replies to it with the "HTTP 400" error. 





For example (working sample): 


<?php


$stream = stream_context_create(Array("http" => Array("method"  => "GET",


                                                      "timeout" => 20,


                                                      "header"  => "User-agent: Myagent",


                                                      "proxy"   => "tcp://my-proxy.localnet:3128",


                                                      'request_fulluri' => True /* without this option we get an HTTP error! */


                                )));





if ( $fp = fopen("http://example.com", 'r', false, $stream) ) {


    print "well done";


}


?>

watch your case when using methods (POST and GET)...it must be always uppercase. in case of you write it in lower case it wont work.

Note that if the server is not able to 'getaddresses' change the name to an ip address and that'll sort that out for internal looking calls and posts.
