用jQuery和Ajax远程POST请求 [英] Remote POST request with jQuery and Ajax

问题描述

我需要做一个POST请求远程域trhough阿贾克斯，我知道有同源策略的限制，但我读过，也有可能使PHP的桥梁我的服务器转发请求

I need to do a POST request to a remote domain trhough Ajax, I know there is the restriction of the Same-Origin Policy but I've read that could be possible make a bridge in PHP on my server to forward the request.

事实上，我已经不是如何写这个桥，我无法找到的信息在谷歌的想法。
我想我需要使用卷曲。

The fact is that I've not idea of how to write this bridge and I can't find info on Google.
I guess I need to use CURL.

有人能解释我如何写一个？

Can someone explain me how to write one?

推荐答案

如果你需要代理或桥，你可以尝试如下： 你可以实现一个简单的AJAX调用到PHP脚本和重定向POST给你想要的另一台服务器。

If you need a proxy or "Bridge", you can try as below: You can achieve a simple AJAX call to that PHP script and redirect that POST to another server you desired.

它是如何工作的：

1. 创建Proxy.php和粘贴内容。
2. 请在页面最初将请求发送一个Ajax请求proxy.php目标服务器来代替。
3. 该请求将被重定向到目标服务器。
4. 您可以选择设置选项 CURLOPT_RETURNTRANSFER 如果你想要的结果。

1. Create Proxy.php and paste the content.
2. Make a page originally sends request to send an AJAX request to proxy.php instead of the target server.
3. The request will be redirected to the target server.
4. You can optionally set option CURLOPT_RETURNTRANSFER if you want the result.

请记住为把一些服务器的身份验证方法首先，因为我已经写的无在这个例子中，或该网页将是一个很好的垃圾机

Please remember to put some server authentication methods first, as I have written none in the example, or that page would be a nice spam machine

编辑：使用您的服务器提交的故障请求到目标服务器我的意思是。反正也不是那么糟糕加入一些简单的身份验证用户：）的

<?php
/* You might want some authentication here */
/* check authentication */
/* Authentication ended. */
$url = 'http://target.com/api'; //Edit your target here
foreach($_GET as $getname => $getvar) {
    $fields[$getname] = urlencode($getvar); //for proxying get request to POST.
}

foreach($_POST as $postname => $postvar) {
    $fields[$postname ] = urlencode($postvar); //for proxying POST requests.
}
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

我假定你知道POST发送Ajax请求已经的方式。如果不知为何，你都没有，只是尝试读取 http://www.openjs.com/scripts/jx/jx.php

I assumes you know the way of sending POST ajax request already. If somehow you are not, just try to read http://www.openjs.com/scripts/jx/jx.php
