Java Bean 返回值为 Null

Question

我在 post 请求后返回值出现问题，响应字符串包含请求的 JSON 文本，但 dataBean 为 null ??

   @Override
    public wDataBean doInBackground(Void... params) {
           wDataBean dataBean = new wDataBean();


        try {

            Response response = client.newCall(request).execute();
            String responseString = response.body().string();
            JSONObject jsonObject = new JSONObject(responseString);
            Gson gson = new Gson();

            dataBean = gson.fromJson(jsonObject.toString(), wDataBean.class);

            }
        catch (final IOException e)
        {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                   Toast.makeText(MainActivity.this,e.getMessage(),Toast.LENGTH_SHORT).show();
                }
            });
        } catch (JSONException e) {
            e.printStackTrace();
            Toast.makeText(MainActivity.this,e.getMessage(),Toast.LENGTH_SHORT).show();
        }

        return dataBean;
    }

这是响应的示例:

  { "IsOK":true,
    "Response":"Logged in successfully",
    "MyArray":{ "user":"35",
                "email":"email@domain.com",
                "img":"https:\/\/www.mywebsite.com\/uploads\/136_image.png",
                "fname":"First Name",
                "lname":"Last Name",
                "myToken":
                    {   
                        "auth":"xyzxyzyxyzxyzxyzxyzxyzxyzxyzxyzxyzxyz",
                        "expiry":"1980-01-01 00:00:00"
                    }
              },
     "myToken":{}
   }

wDataBean.java

public class wDataBean {

private Main1 main;

public Main1 getMain() {return main;}

public void setMain(Main1 main) {this.main = main;}

class Main1 {

    boolean IsOK;
    String Response;
    JSONArray MyArray;
    int user;
    String email;
    String img;
    String fname;
    String lname;
    JSONArray myToken;
    String auth;
    Date expiry;

    public boolean isOK() {return isOK();}
    public int getUser() {return user;}
    public JSONArray getMyArray() {return MyArray;}
    public String getEmail() {return email;}
    public String getImg() {return img;}
    public String getResponse() {return Response;}
    public Date getExpiry() {return expiry;}
    public JSONArray getMyToken() {return myToken;}
    public String getAuth() {return auth;}
    public String getFname() {return fname;}
    public String getLname() {return lname;}
    public void setAuth(String auth) {this.auth = auth;}
    public void setEmail(String email) {this.email = email;}
    public void setExpiry(Date expiry) {this.expiry = expiry;}
    public void setFname(String fname) {this.fname = fname;}
    public void setImg(String img) {this.img = img;}
    public void setLname(String lname) {this.lname = lname;}
    public void setMyArray(JSONArray myArray) {MyArray = myArray;}
    public void setMyToken(JSONArray myToken) {this.myToken = myToken;}
    public void setOK(boolean OK) {IsOK = OK;}
    public void setResponse(String response) { Response = response;}
    public void setUser(int user) { this.user = user;}
  }

}

目标是从myToken获取“auth”和“expiry”

这应该是你的 Bean 类 -

 public class WDataBean {

    @Expose
    private Boolean isOK;
