Android客户端无法连接到PHP服务器

Question

作为字符串的图像应该从android客户端发送到PHP服务器 服务器端代码就是这个 *

<?php
    echo "fata";
    if (isset($_POST['image'])) {
      $data = $_POST['image'];
      $name= $_POST['name'];

      $decodedImage = base64_decode($image);
      $image_file=time().rand(1111,9999);
      $name=$name.$image_file;
      $base_path='/var/www/html/CGIR/Uploads/';


      file_put_contents($base_path.$name.".jpg", $decodedImage);
      echo "wow!!!! You did it awesome man ...!!!";
       }
      echo "here";

    ?>

*

在客户端出现错误：超时。所以，我最初将时间设置为5000。但是客户端一直试图连接它并且它没有连接到服务器。我尝试在浏览器中使用相同的上传网址，但它确实有效。而apache也正常运行。我也试过禁用防火墙。但似乎没有任何效果。 这是android方面
