【问题描述】：

我想在我的脚本中使用 fsockopen 将一些发布数据传递给我服务器上的另一个 php 脚本。我已经对其进行了测试，除非您的网站上有路由，否则实现起来非常简单。

这是我的工作示例（在服务器上没有路由）：

socket_post.php

<?php
header('Content-type: text/plain');

$fp = fsockopen('example.com', 80, $errno, $errstr, 30);

$vars = array(
   'filename' => 'article.txt',
   'data' => 'Hello world'
);

$content = http_build_query($vars);

fwrite($fp, "POST /sockets/receive_data.php HTTP/1.1\r\n");
fwrite($fp, "Host: example.com\r\n");
fwrite($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
fwrite($fp, "Content-Length: ".strlen($content)."\r\n");
fwrite($fp, "Connection: close\r\n");
fwrite($fp, "\r\n");

fwrite($fp, $content);
//fclose($fp); // Closes socket immediately without waiting for response
//echo "Done\r\n";

while (!feof($fp)) {
   echo fgets($fp, 1024);
}

receive_data.php

<?php

extract($_POST);
sleep(10);
file_put_contents($filename, $data);

因此，它在我的测试服务器上运行良好，但是当我尝试使用 OpenCart CMS 实现此脚本时，由于 OpenCart 的控制器路由而失败。

这是 OpenCart 脚本的一个版本：

socket_post.php

<?php
class ControllerSocketsSocketPost extends Controller {
   public function index() {
      header('Content-type: text/plain');

      $fp = fsockopen("example.com", 80, $errno, $errstr, 30);

      $vars = array(
         'filename' => 'article.txt',
         'data' => 'Hello world'
      );

      $content = http_build_query($vars);

      fwrite($fp, "POST https://example.com/index.php?route=sockets/receive_data HTTP/1.1\r\n"); // !!!THE MAIN PROBLEM HERE!!!
      fwrite($fp, "Host: example.com\r\n");
      fwrite($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
      fwrite($fp, "Content-Length: ".strlen($content)."\r\n");
      fwrite($fp, "Connection: close\r\n");
      fwrite($fp, "\r\n");

      fwrite($fp, $content);

      //fclose($fp); // Closes socket immediately without waiting for response
      //echo 'Done';

      while (!feof($fp)) {
         echo fgets($fp, 1024);
      }
   }
}

receive_data.php

<?php
class ControllerSocketsReceiveData extends Controller {
   public function index() {
      extract($this->request->post);
      sleep(10);
      file_put_contents($filename, $data);
   }
}

因此，它应该在同一目录中创建"article.txt" 文件并在页面上呈现HTTP/1.1 200 OK 状态，但由于路由和html 输出<p>The document has moved <a href="https://www.example.com/index.php?route=sockets/receive_data">here</a>.</p>，它会获得HTTP/1.1 302 Found 状态。

在这种情况下如何处理 OpenCart 的路由？任何建议将不胜感激，谢谢！

【问题讨论】：

你在用 apache 做 opencart 吗？
是的，Apache 2.2.31，PHP 5.3.29
在POST URL中直接使用php文件路径即/server/xxx/filename.php
我刚刚将其更改为fwrite($fp, "POST https://example.com/catalog/controller/sockets/receive_data.php HTTP/1.1\r\n");，但结果与以前相同。
那不行，你为什么要在这里扩展控制器？将这个 index.php 代码放在服务器根目录 (server_root/recieve.php) 内的一个简单 php 文件中，然后 POST 到 example.com/recieve.php

【解决方案1】：

只需要通过 localhost 建立连接并找到未使用的端口：

socket_post.php

<?php
class ControllerSocketsSocketPost extends Controller {
public function index() {
    header('Content-type: text/plain');

    $fp = fsockopen('localhost', 8080, $errno, $errstr, 30);

      if ($errno) {
        echo "ERRNO: $errno \r\n";
        echo "ERRSTR: $errstr \r\n";
      } else {

        $vars = array(
            'mail_to' => 'your@email.com',
            'message' => 'Hello world'
        );

        $content = http_build_query($vars);

        if ($fp) {
            fwrite($fp, "POST /catalog/controller/sockets/receive_data.php HTTP/1.1\r\n");
            fwrite($fp, "Host: localhost\r\n");
            fwrite($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
            fwrite($fp, "Content-Length: ".strlen($content)."\r\n");
            fwrite($fp, "Connection: close\r\n");
            fwrite($fp, "\r\n");

            fwrite($fp, $content);
            fclose($fp); // Complete script execution without waiting for the response
            echo "Done\r\n";
/*
            while (!feof($fp)) { // Wait for response if socket connection not closed yet
                echo fread($fp, 1024);
            }
*/
        }
      }
   }
}

接收器应该只是简单的php脚本，在这种情况下如何处理OpenCart控制器：

receive_data.php

<?php
extract($_POST);
sleep(10);

mail($mail_to, 'Async PHP', $message);

希望对某人有所帮助。
