一个请求,同时分发到多个服务器,
正常的是: A ============> B
现在想实现的是:
--------------> C
A ======> B ---------------> D
---------------> E
如果是 GET请求,就处理一下 URL请求即可,但 POST 请求,还需要处理数据,
处理数据:
如果是键值对方式的,使用 $_REQUEST 获取整个键值对;
$post_data = $_REQUEST; ??//则会获取 整个请求中的键值对,返回结果为数组;
如果是以流的方式的,则使用:
$post_data = file_get_contents("php://input");
获取完数据后,就用代码来进行转发,需要使用 curl:
** 如果需要根据进来的 url进行判断,可以使用 $_SERVER[‘REQUEST_URI‘]; // 获取的是 url中,domain后的部分,如: https://www.google.com/abc.php ==> /abc.php
<?php ???/** ????* 发送post请求,而且data是键值对形式 ????*/ ???function send_post($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 $result; ???} ???/** ????* 发送post请求,而且data是流的形式 ????*/ ???function send_post_content($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 $result; ???} ???// 转发键值对请求 ????if (isset($_REQUEST) && !empty($_REQUEST)) { ???????$url1 = "http://test1.php"; ???????$url2 = "http://test2.php"; ???????????????$request = $_REQUEST; ???????echo send_post($url1, $request); ???????/*echo*/ send_post($url2, $request); ???} ????else { ???????// 转发流请求 ???????$url3 = "http://test3.php"; ???????$url4 = "http://test4.php"; ???????????????$request = file_get_contents("php://input"); // $_REQUEST; ???????echo send_post_content($url1, $request); ???????/*echo*/ send_post_content($url2, $request); ???}
