JSON自动添加反斜杠 [英] JSON adding backslash automatically

问题描述

我正在尝试使用Gson将Java对象转换为json.但是当我尝试打印出来时，我得到了这个JSON

I am trying to convert a java object to json using Gson. But when i tried printing it out.I got this JSON

{"user":"{\" email \:\" [e-mail] \，\" lastName \:\" Las \，\" name \:\" amy \， \密码\":\"qwe123 \"，\电话\":\"8901245244 \"}}

{"user":"{\"email\":\"[e-mail]\",\"lastName\":\"Las\",\"name\":\"amy\",\"password\":\"qwe123\",\"phone\":\"8901245244\"}"}

我尝试过

s.replace("\\"，" \") 但它既无济于事，也不是一个好方法.

s.replace("\\"", "\"") but neither it helps nor its a good approach.

我还经历了各种链接，但答案却模棱两可.

Further I have gone through various links but answers are ambiguous.

这是我的User类toString方法

This is my User class toString method

 public class User implements Serializable
{ ...
@Override
public String toString()
{   return "User{" +
            "first_name:" + name+
            ", last_name:" + lastName+
            ", mobile:" + phone+
            ", email:" + email+
            ", password:" + password+
            "}";
}

我想它甚至都没有调用此toString方法.

I guess its not even calling this toString method.

这是我如何转换为JSON

and here is how am I converting to JSON

        User u=new User(name,lastName,email,phone,password);
        Gson userGson=new GsonBuilder().create();
        String jo=userGson.toJson(u);

        JSONObject params=new JSONObject();
        params.put("user",jo);
        Log.e("in register",params.toString());

感谢您的帮助.

推荐答案

您已经将其转换为JSON字符串，然后将其粘贴到JSON对象中，该对象会自动转义JSON字符串.尝试这样的事情:

You've already converted it to a JSON string, then you stick that into a JSON object which automatically escapes the JSON string. Try something like this:

User u=new User(name,lastName,email,phone,password);
Gson userGson=new GsonBuilder().create();
JSONObject params = new JSONObject();
params.put("user",user);
Log.e("in register", userGson.toJson(params));
