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。获取状态后，用户将被重定向到页面。注册过程最多需要 10 秒才能完成，因此我需要使用提供的网址/链接再次检查注册状态。
PHP 不允许 header 位置重定向，因此我所做的是使用 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);

如果您对我如何实现这一目标有任何建议，我将非常感激。谢谢。
最佳答案
在启动 ajax 调用的窗口已重定向到另一个 URL 后，您将无法继续访问该 ajax 调用的结果。整个上下文已被浏览器清理并且不再可用。
您需要停止重定向，直到完成 ajax 调用。一些可能性:
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，您可以访问其结果，但同时也会显示新内容。
在 ajax 调用完成(在其完成处理程序中)之前不要执行重定向。
打开一个新窗口进行重定向，当 ajax 调用完成时，关闭该窗口。如果这些窗口位于同一域中，您可以访问它们之间的数据。就我个人而言，如果可能的话，我会避免额外的窗口。
