我想使用php作为代理服务器，将json数据传递到Web服务，我在做什么错？

Question

Below is php script I am trying to use as proxy to pass two parameters (username and password) to a web service to return data in json format.

This is a workaround to the famed same domain limitation policy.

I keep getting invalid username or password.

The ajax file is trying to pass two parameters to the webservice via php proxy script.

Here is a snippet of the ajax file:

var uname = $("#user").val();
var upass = $("#pass").val();

    $.post("proxyurl.php",
      { data: JSON.stringify({ LoginName: uname,Password: upass }) })
        .done(function(data) {

Below is proxyurl.php

  <?php

    $ch = curl_init("http://myotherdomain.com/getUserDetails");
    $strUser = $_POST["uname"];
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt ($ch, CURLOPT_POSTFIELDS,"LoginName=".urlencode($strUser));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);      
    curl_close($ch);
    echo $output
  ?>

Thanks in advance for your assistance

You're actually sending over LoginName and Password to your proxy script, not uname .

As well, curlopt_Postfields is perfectly happy to accept an array of key/value pairs and will encode it for you. There is no need to manually building a key=value string yourself.

curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);

is technically all you'd really need to do.
