这是一个非常不寻常的问题。我只是为httpcomponents和httpurlconnection编写了一个测试，两者都将3个键值字符串对发布到一个php文件中，php会将3个字符串组合在一起并返回。这两个测试都在我自己的 linux 服务器上运行良好，这是一个虚拟机中的 Debian Linux。但是，当我将 php 文件上传到由 webhostingpad.com 托管的网站时，只有 httpcomponents 测试有效。httpurlconnection 一将获得 403 禁止作为错误代码。
任何人有任何提示我应该做什么？
这是我的文件：
<?php
$s1 = $_POST['s1'];
$s2 = $_POST['s2'];
$s3 = $_POST['s3'];
echo "$s1 $s2$s3";
