JSON+；PHP+；Java-Android登录mysql

我有个问题。。。 当用户注册时，我试图将设备的udid存储到我的数据库中。。。 我在logcat中发现了这个错误：

10-18 17:17:08.141: E/JSON(1712): <br />
10-18 17:17:08.141: E/JSON(1712): <b>Warning</b>:  Missing argument 4 for DB_Functions::storeUser(), called in /home/matbest1/public_html/android_login_api/index.php on line 64 and defined in <b>/home/matbest1/public_html/android_login_api/include/DB_Functions.php</b> on line <b>25</b><br />

php代码：

 public function storeUser($name, $email, $password, $uid) {
    $uuid = $uid;
    $hash = $this->hashSSHA($password);
    $encrypted_password = $hash["encrypted"]; // encrypted password
    $salt = $hash["salt"]; // salt
    $result = mysql_query("INSERT INTO users(unique_id, name, email, encrypted_password, salt, created_at) VALUES('$uuid', '$name', '$email', '$encrypted_password', '$salt', NOW())");
    // check for successful store
    if ($result) {
        // get user details 
        $uid = mysql_insert_id(); // last inserted id
        $result = mysql_query("SELECT * FROM users WHERE uid = $uid");
        // return user details
        return mysql_fetch_array($result);
    } else {
        return false;
    }
}

有人能帮我吗？我是新来的。。。非常感谢。

服务器响应包含一个以HTML显示的PHP错误

因此，android应用程序无法解析任何JSON是正常的

首先，您需要确保android应用程序发送所有需要的信息（PHP等待的4个参数），因为PHP错误清楚地告诉您它缺少参数#4:$uid

试试看

print\r（$\u请求）
在php文件的开头，查看php是否接收到所有参数。。如果不是：问题出在android应用程序中（uid是字符串？整数？需要转换吗？
值，因此在解析udid时出现了一些错误？请阅读错误消息。我看不出有什么不对吗，我是新来的，你能帮我吗？我不知道我能帮你什么，除了告诉你你的JSON格式不正确。你需要弄清楚它为什么格式不正确。堆栈溢出不是调试器。
