android - 当数据是字符串而不是对象时，如何在 android 中使用解析相同的 json 响应？

Question

当我收到响应时，成功类完美运行。但是当它失败时，它给了我错误。

URL传入失败数据时的响应:

{
  "success": -1,
  "message": "Invalid username or password",
  "data": ""
}

URL传入正确数据时的响应:

{
  "success": 1,
  "message": "User successfully logged in",
  "data": {
    "userId": 219,
    "userName": "mp",
    "picture": "219.png",
    "isBo": false,
    "isPo": true,
    "isHm": true,
    "hmProfileCompletionStatus": 3,
    "poProfileCompletionStatus": 2,
    "poPhoto": null,
    "hmPhoto": null,
    "custStripeToken": "xxx",
    "accountStripeToken": "xx",
    "bgcStatus": true,
    "idCardStatus": true,
    "isInsured": null,
    "amISponsered": false,
    "hmRating": null,
    "poRating": null,
    "email": "xxx@gmail.com"
  }
}

UserResponse.java

@Getter
@Setter
public class UserResponse{
    private int success;
    private String message;
    private User data;
}

错误

java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 64 path $.data

Answer 1

这是不可能的。在你的情况下应该是这样的

{
  "success": -1,
  "message": "Invalid username or password",
  "data": {}
}

让你的后端服务团队改成空对象，这样就可以重复使用同一个reponse对象
