我通过http://www.jsonschema2pojo.org/从我的JSON自动生成了POJO 我用它来改造。 这是JSON：

总是失败回应......任何想法可能是什么原因？
这是我的改造界面：
public interface IGDBApi {
@Headers({
"Accept: application/json",
"user-key: (removed for this post)"
})
@GET("games/?search=TheWitcher3&fields=id,name,first_release_date,cover.url,screenshots.url,videos.video_id")
Call<List<Result>> loadFollowers();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api-2445582011268.apicast.io/")
.addConverterFactory(GsonConverterFactory.create())
.build();
}
这是我在主要活动中运行改造的方法：
public void runretrofit(){
//Starts Retrofit
final IGDBApi gitHubApi = IGDBApi.retrofit.create(IGDBApi.class);
//Sets up up the API call
Call<List<Result>> call = gitHubApi.loadFollowers();
//Runs the call on a different thread
Log.v("URL Called", call.request().url() + "");
call.enqueue(new Callback<List<Result>>() {
@Override
public void onResponse(Call<List<Result>> call, Response<List<Result>> response) {
Log.v("RESULT", "JSON: "+new Gson().toJson(response.body()) );
}
@Override
public void onFailure(Call<List<Result>> call, Throwable t) {
Log.v("RESULT Fail", "Request failed");
}
});
}
答案 0 :(得分：1)
首先：
制作
char *m_strncpy(char *str1, int count) {
int i;
char *new_str = malloc(count + 1); // +1 for the NUL terminator
if (new_str != NULL)
{
for (i = 0; i < count; i++) { // copy count first chars
new_str[i] = str1[i];
}
new_str[i] = 0; // NUL terminate the string
}
return new_str;
}
到
private Integer firstReleaseDate;
<强>第二
检查所有包含值的列表项。如果某些项具有浮点值，则会抛出错误。
