根据注册响应JSON，“RegisteredMember”是一个数组而不是对象，这是错误的
接下来，很明显，您得到了一个错误{“success”：0，“message”：“未设置参数”}，并且JSON没有“RegisteredMember”，因此出现了异常
因此，您可以检查json中是否存在该值
if(your_json_object.has("RegisteredMember")){
//Get the JSONArray, take a loop and get individual objects
}
然后继续
编辑
据我所知，最初您有JSONException，但在响应中没有得到“RegisteredMember”数组。因此，基于此，您可以遵循以下代码
JSONObject jsonObject = new JSONObject(response);
int success = jsonObject.getInt("success");
String message = jsonObject.getString("message");
if(jsonObject.has("RegisteredMember")){
JSONArray jsonArray = jsonObject.getJSONArray("RegisteredMember");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject regMemberObject = jsonArray.getJSONObject(i);
String phone = regMemberObject.getString("phone");
String firstName = regMemberObject.getString("first_name");
int userID = regMemberObject.getInt("user_id");
}
}
//Similar with the login Json as it too has same format
JSONObject JSONObject=新的JSONObject（响应）；
int success=jsonObject.getInt（“success”）；
String message=jsonObject.getString（“消息”）；
if（jsonObject.has（“RegisteredMember”））{
JSONArray JSONArray=jsonObject.getJSONArray（“RegisteredMember”）；
for（int i=0；i
我没有检查你的密码。我只是给出一个通用的解决方案。您将拥有响应Json的特定格式&将以相同的方式解析Json。如果出现一些错误，服务器可能不会向您发送相同格式的json，因此您可能会收到一个异常。因此，验证并解析json.has（String）首先进行验证，以便以后不会出现异常。对代码进行以下更改
并按如下方式解析您的响应：
try {
JSONObject jObj = new JSONObject(response);
int intError = jObj.getInt("success");
Boolean error = (intError < 0) ? true : false;
if (!error){
// user successfully logged in
// Create login session
session.setLogin(true);
JSONArray verifiedMember = jObj.optJSONArray("VerifiedMember");
for (int i =0;i<verifiedMember.length();i++){
JSONObject rootObj = verifiedMember.getJSONObject(i);
String userId = rootObj.getString("user_id");
String first_name = rootObj.getString("first_name");
String email = rootObj.getString("phone");
// Inserting row in users table

试试看{
JSONObject jObj=新的JSONObject（响应）；
int interor=jObj.getInt（“成功”）；
布尔错误=（intError<0）？真：假；
如果（！错误）{
//用户已成功登录
//创建登录会话
session.setLogin（true）；
JSONArray-verifiedMember=jObj.optJSONArray（“verifiedMember”）；
对于（int i=0；i参数未设置
