Php 无法存储数据JSON

Php 无法存储数据JSON,php,android,json,Php,Android,Json,我试图创建一个注册和登录函数,但JSON无法存储数据,我遇到了问题 这是我从日志中得到的json响应: 02-24 08:24:47.878:E/JSON(2017):{“tag”:“register”,“success”:0,“error”:1,“error_msg”:“registarion中发生错误”} 这是我存储数据的php代码: <?php if (isset($_POST['tag']) && $_POST['tag'] != '') { // get tag

我试图创建一个注册和登录函数,但JSON无法存储数据,我遇到了问题

这是我从日志中得到的json响应:

一个可能的问题是,您可能通过GET方法发送参数,但在PHP脚本中,您试图解析为空的帖子内容。尝试使用
jsonParser.makeHttpRequest(registerURL,“POST”,params)
而不是
jsonParser.makeHttpRequest(registerURL,“GET”,params)

中的内容:$db->storeUser($email,$contact,$password);应该是这里的输入,对吗<代码>参数添加(新的BasicNameValuePair(“电子邮件”),电子邮件);添加(新的BasicNameValuePair(“密码”,password));参数添加(新的BasicNameValuePair(“联系人”,联系人))
仍然得到相同的json响应我的假设是基于这样的想法,即并非所有必需的参数都被传递到
storeUser
函数中。(您可以将接收到的参数包括在响应中进行检查)。如果这个假设不成立,我们需要DB_Function.php内容来继续调查。
