Java Bean返回值爲空

Question

我在post請求後發現返回值有問題，響應字符串包含請求的JSON文本，但dataBean爲空??

@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; 
    } 

這是響應的示例：

{ "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;} 
    } 

}

的目標是讓「權威性」和「expiry」 from myToken

Answer 1

你能告訴我wDataBean類嗎？

但我敢說，這可以解決

Gson gson = new GsonBuilder().setDateFormat("yyyy-mm-dd HH:mm:ss").create(); 

Answer 2

這應該是你的bean類 -
