我有一个脚本，可以将数据发送到 Web 服务并从 Web 服务获取响应。响应是一个链接/url，将用于检查注册状态。我使用 file_get_contents 从提供的 url 获取状态。获得状态后，用户将被重定向到一个页面。注册过程最多需要 10 秒才能完成，因此我需要使用提供的 url/链接再次检查注册状态。

PHP 不允许标头位置重定向，所以我使用 jQuery 和 AJAX 来检查注册状态。它在页面尚未重定向时起作用。但在这种情况下，它不会起作用，因为页面会在 10 秒后检查注册状态之前先重定向到另一个 URL。

我希望这不会令人困惑。

这是我使用的代码：

<?php
    function sendRequest($url, $params)
    {
        $request = curl_init($url); // initiate curl object
        curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response
        curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1)
        curl_setopt($request, CURLOPT_POSTFIELDS, $params); // use HTTP POST to send form data
        curl_setopt($request, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment this line if you get no gateway response.
        $response = curl_exec($request); // execute curl post and store results in $post_response
        curl_close ($request); // close curl object
        return $response;
    }

    function sendJSONRequest($url, $data)
    {             
        $data_string = json_encode($data);
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);               
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);             
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);     
        curl_setopt($ch, CURLOPT_TIMEOUT ,50);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(                       
            'Content-Type: application/json',
            'Accept: application/json',
            'X-MP-Version: 10072013')                      
        );
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        ob_start();
        $result = curl_exec($ch);
        $info = curl_getinfo($ch);
        if ($result === false || $info['http_code'] == 400) {
          return "0";
        } else {
          return $result;
        }
        ob_end_clean();
        curl_close($ch);
    }

    function WriteLog($offer,$values)
    {
        $Filename = "./reports/".$offer.date('Ym').".txt";
        $fh = fopen($Filename, 'a') or die("can't open file");
        $filecontent = date('Y-m-d G:i').',';
        $filecontent .= $values;
        $filecontent .= PHP_EOL;
        fwrite($fh,$filecontent);
        fclose($fh);
    }

如果您对我如何做到这一点有任何建议，我将不胜感激。谢谢。

在启动 ajax 调用的窗口被重定向到另一个 URL 后，您将无法继续访问它的结果。整个上下文已被浏览器清除，不再可用。

在完成 ajax 调用之前，您需要停止重定向。一些可能性：

  1. 从重定向更改为通过 ajax 加载内容，这样您就可以在整个过程中保持原始文档打开，这样 ajax 调用将继续并且您可以访问其结果，但您也显示了新内容。

  2. 在 ajax 调用完成（在其完成处理程序中）之前，不要进行重定向。

  3. 为重定向打开一个新窗口，当 ajax 调用完成时，关闭该窗口。如果这些窗口在同一个域中，您可以访问它们之间的数据。就个人而言，如果可能的话，我会避免额外的窗口。

使重定向成为successjQuery AJAX 调用回调的一部分。

如果您在 AJAX 调用期间重定向，那么它基本上会丢失，因为不再有任何注册的回调来处理返回的数据。您也不能在新页面上连接回调。
