예상 BEGIN_OBJECT하지만 GSON

Question

와 STRING 내가 좋아하는 Retrofit 2의 응답을 받고 있어요

이었다

{"error":"0","posts":[{"account_id":61,"industry_id":1,"company_id":1,"profession_id":1,"description":"Demo Post 13","tags":"Cinema","created_at":"2016-12-05 10:47:41","totalFlags":0,"totalComments":0},{"account_id":65,"industry_id":2,"company_id":13,"profession_id":11,"description":"Demo Post 12","tags":"Cinema","created_at":"2016-12-05 10:47:33","totalFlags":0,"totalComments":0},{"account_id":65,"industry_id":2,"company_id":13,"profession_id":11,"description":"Demo Post 11","tags":"Culture","created_at":"2016-12-05 10:47:17","totalFlags":0,"totalComments":0}]}

을 나는 두 항목 선언 :

public class FeedServiceResponse implements Serializable { 

    private String error; 
    private FeedServiceResponseItem[] posts; 

    // getters/setters omitted 
} 

및

public class FeedServiceResponseItem implements Serializable { 

    private int account_id; 
    private int industry_id; 
    private int company_id; 
    private int profession_id; 
    private String description; 
    private String tags; 
    private String created_at; 
    private String totalFlags; 
    private int totalComments; 

// again getters/setters omitted 

} 

하지만를 내부 onResponse()Retrofit에서 데이터를 deserialize하려고 할 때 :

FeedServiceResponse feedServiceResponse = gson.fromJson(response.body().toString(), FeedServiceResponse.class); 

나는 다음과 같은 오류 얻을 : StackOverflow에

내가 읽고 기타 질문/답변을하지만 캔트 내가 뭘 잘못 찾을 수가.

Answer 1

서버가 JSON 데이터에 응답하지 않는 것으로 보입니다. 검사 도구를 사용하거나 로깅을 활성화하여 검사해야합니다.
