java - jsonobject 第 19 行有未终止的对象？

Question

我是 Android 开发新手，正在使用 volley 制作简单的登录应用程序并从服务器获取 json 响应，如下所示:

json 响应:-

 {"loginResult":"{\"UserLoginID\":864,\"UserID\":864,\"EmployeeCode\":\"PI4264\",\"Password\":\"XXXX\",\"IsPasswordChanged\":false,\"ModuleName\":\"XXX\",\"ModuleID\":1,\"EmployeeName\":\"XXXX  \"}"}

当我尝试解析这个 jsonobect 时，我得到:

在 19 jsonException 处未终止的对象到目前为止我尝试解析的是

 String resp = response.toString().replaceAll("\\\\", "");

                    try {
                        JSONObject yog = new JSONObject(resp);
                        int yogs=yog.getInt("UserID");
                        Toast.makeText(getApplicationContext(), resp, Toast.LENGTH_SHORT).show();

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

不知道我在哪里犯了错误，有人可以教我我这样做的方法是否正确!!!

您应该将代码更改为:

String resp = response.toString().replaceAll("\\\\", "");
                    try {
                        JSONObject yog = new JSONObject(resp);
                        JSONObject loginObject = new JSONObject(yog.getString("loginResult")); 
                        int yogs=loginObject.getInt("UserID");
                        Toast.makeText(getApplicationContext(), resp, Toast.LENGTH_SHORT).show();

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

我执行了代码，没有收到错误:

JSONObject yog = new JSONObject("{\"loginResult\":\"{\\\"UserLoginID\\\":864,\\\"UserID\\\":864,\\\"EmployeeCode\\\":\\\"PI4264\\\"," +
                        "\\\"Password\\\":\\\"XXXX\\\",\\\"IsPasswordChanged\\\":false,\\\"ModuleName\\\":\\\"XXX\\\",\\\"ModuleID\\\":1,\\\"EmployeeName\\\":\\\"XXXX " +
                        "\\\"}\"}");
JSONObject loginObject = new JSONObject(yog.getString("loginResult"));
int yogs=loginObject.getInt("UserID");
Toast.makeText(getApplicationContext(), String.valueOf(yogs), Toast.LENGTH_SHORT).show();
