PHP Implementation Request shunt

A request, distributed to multiple servers at the same time,

The normal is: A ============> B

What you want to achieve now is:

--------------> C

A ======> B---------------> D

---------------> E

If it's a GET request, just process the URL request, but the POST request also needs to process the data,

Working with Data:

If it is a key-value pair, use $_request to get the entire key-value pair;

$post _data $_request;   // a key-value pair is obtained from the entire request, and the result is an array;

If it is in a stream, then use:

$post _data file_get_contents ("Php://input");

Once the data has been obtained, the code is used to forward it, and curl is required:

* * $_server[' Request_uri ' can be used if it is necessary to judge by the incoming URL; Gets the part of the URL, after domain, such as: https://www.google.com/abc.php ==>/abc.php

<?PHP/** * Send a POST request, and data is a key-value pair form*/    functionSend_post ($url,$post _data) {        $postdata=Http_build_query($post _data); $options=Array(                    ' http ' =Array(                                    ' Method ' = ' POST ', ' header ' = ' content-type:application/x-www-form-urlencoded ', ' Content ' =$postdata, ' timeout ' = 15 * 60                                )                    ); $context=stream_context_create($options); $result=file_get_contents($url,false,$context); return $result; }    /** * Send a POST request, and data is in the form of a stream*/    functionSend_post_content ($url,$postdata) {        $options=Array(                    ' http ' =Array(                                    ' Method ' = ' POST ', ' header ' = ' content-type:application/x-www-form-urlencoded ', ' Content ' =$postdata, ' timeout ' = 15 * 60                                )                    ); $context=stream_context_create($options); $result=file_get_contents($url,false,$context); return $result; }    //forwarding a key-value pair request    if(isset($_request) &&!Empty($_request)) {        $url 1= "http://test1.php"; $url 2= "http://test2.php"; $request=$_request; EchoSend_post ($url 1,$request); /*Echo*/Send_post ($url 2,$request); }     Else {        //forward Stream Request        $url 3= "http://test3.php"; $url 4= "http://test4.php"; $request=file_get_contents("Php://input");//$_request;        EchoSend_post_content ($url 1,$request); /*Echo*/Send_post_content ($url 2,$request); }
