改造无法正确解析正文

Posted 2023-03-22

【中文标题】改造无法正确解析正文

【英文标题】：Retrofit can't parse body correctly

【发布时间】：2018-05-17 16:26:54

【问题描述】：

我无法使用 Retrofit2 + Gson 正确解析我的 Web 服务的响应。 我已经实现了类似的响应，并且它们都可以正常工作。当响应正文返回自定义对象数组时会出现问题。

我已经阅读了许多来自 *** 的回复，并且我使用 http://www.jsonschema2pojo.org/ 制作了我的课程，但没有办法...

我粘贴了我所有的代码。希望您能够帮助我。谢谢！

改造客户端

public class RetrofitClient 

    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseUrl) 
        if (retrofit==null) 
            retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        
        return retrofit;
    

改造响应

【问题讨论】：

androidhive.info/2016/05/…

不确定是否应该同时使用公开和序列化名称，请参阅：***.com/questions/34752200/…

发送到服务器的请求数据是否正确，您是否使用与您看到响应的相同的请求数据？

@StarterPack 我只是先尝试​​了仅使用暴露，然后仅使用了 SerializedName，但它们都没有工作

哈哈，我日常生活中的一个故事。乐意效劳。干杯！！

【参考方案1】：

在您的 RankingResponse 类中替换以下内容：

@SerializedName("data")
@Expose
private List<Datum> data = null;

与：

@SerializedName("data")
private List<Datum> data =  new ArrayList<Datum>();
