Android注册无法正常工作

我正在尝试为我的应用编写注册系统，但它不起作用，我不知道为什么。

我在php中编写了一个api，它包含3个文件：

这里是index.php 

<?php
require_once 'Functions.php';

$func = new Functions();

if($_SERVER["REQUEST_METHOD"] == 'POST'){
     $data = json_decode(file_get_contents("php://input"));

     if(isset($data -> operation)){
         $operation = $data -> operation;

         if(!empty($operation)){
              if($operation == 'register'){
                  if(isset($data -> user) && !empty($data -> user) && isset($data -> user -> firstname) && isset($data -> user ->lastname) && isset($data -> user -> birthday) && isset($data -> user -> gender) && isset($data -> user -> email) && isset($data -> user -> username) && isset($data -> user -> password)){

                    $user = $data -> user;
                    $firstname = $user -> firstname;
                    $lastname = $user -> lastname;
                    $birthday = $user -> birthday;
                    $gender = $user -> gender;
                    $email = $user -> email;
                    $username = $user -> username;
                    $password = $user -> password;

                    if($func -> isEmailValid($email)){
                        echo $func -> registerUser($firstname, $lastname, $gender, $birthday, $email, $username, $password);
                    }else{
                        echo $func -> getMsgInvalidEmail();
                    }

                }else{

                }
             }else if($operation == 'login'){
                 if(isset($data -> user) && !empty($data -> user) && isset($data -> user -> email) && isset($data -> user -> password)){

                     $user = $data -> user;
                     $email = $user -> email;
                     $password = $user -> password;

                     echo $func -> loginUser($email, $password);

                 }else{
                     echo $func -> getMsgInvalidParam();
                 }
             }else if($operation == 'chgPass'){

我失败了＆＃39;在日志中点击并在应用程序中注册我得到小吃栏消息＆＃39;在第1行第1列＆＃39;输入结束。

我的php文件保存在我的网站www.novee.de/apps/raivel/android_api /..'

还有一个Constants.java文件，但我认为发布它并不重要。我知道这是很多代码，但我正在寻找解决方案，因为几天甚至几周都找不到。所以我希望你们能花点时间帮助我理解这个错误。

如果我对这篇文章说错了，请告诉我。

1 个答案:

答案 0 :(得分：1)

在创建时删除密码哈希中的salt。

使用password_hash时需要使用盐，这是在password_hash内部处理的。

盐是随机的，并在创建时使用密码（password_hash）进行连接，但在验证时没有使用密码（password_verify），因此无法匹配。

PHP 5.5提供a native password hashing API，以安全的方式安全地处理hashing和verifying passwords。
