我在我的 Main 类login=root&password=rootauthenthication.php使用Authorize(String login, String password)来自AuthMediator(扩展 PHPMediator)的方法发送 POST 请求。

问题是 - 我的 PHP 脚本从来没有收到任何东西($_SERVER['QUERY_STRING'] 是空的,但是当我尝试手动执行 GET 时 - 它不是)。当所有代码都在一个类(主类)文件中时,它起作用(即 PHP 正在获取请求并处理它们)。但是在我把它分成不同的文件之后,它就停止了工作。

也许有一些访问修改器在玩一些有趣的把戏?我是 Java 新手,但我仍然不完全了解它们会产生哪些副作用。

这是我的authentication.php

<?php
if(isset($_POST['login']) && isset($_POST['password']) )
{
    $login=$_POST['login'];
    $password=$_POST['password'];

    $userfile_path="../users/".$login;

    if(!file_exists($userfile_path))
    {
        echo "ERR_USER_INVALID";
    }
    else
    {
        $hash=md5($login.$password);

        $userfile=fopen($userfile_path,"r");
        if($userfile!=FALSE)
        {
            if(fgets($userfile)==$hash)
            {
                echo "OK_USER_VALID";
            }
            else
            {
                echo "ERR_USER_INVALID";
            }
            fclose($userfile);
        }
        else
        {
            echo "ERR_OPENING_USER_FAILED";
        }
    }

}
else
{
    echo "ERR_AUTH_MALFORMED_POST_REQUEST(".$_SERVER['QUERY_STRING'] .")";
}

?>

AuthMediator.class

import Constants.MagicConstants;

public class AuthMediator extends PHPMediator {

    public AuthMediator() throws Exception {
        super(MagicConstants.AUTH_URL);
    }

    public String Authorize(String login, String password) {
        String _data="login="+login+"&password="+password;
        try {
            this.sendData(_data);
            this.receiveData();
        } catch (Exception ex) {
            return "ERR_EXCEPTION";
        }

        return this._response;
    }
}

POST 请求不会生成查询字符串。

嗯,我发现了错误。

this._bufRead=new BufferedReader(new InputStreamReader(_urlConn.getInputStream()));

必须在将消息发送到服务器后进行初始化。
