我已经尝试了几乎所有的解决方案，但仍然无法解决问题。响应正在日志中显示，但它仍然显示一个空白片段。也许我没有正确解析它？我该怎么办？那？ JSON响应：

您可以通过JsonElement接收响应，并通过任何方法将其反序列化到您的List。
@FormUrlEncoded
@POST("getFavorites.php")
Call<JsonElement> getFavs(@Field("user_id") int user_id);
响应：
call.enqueue(new Callback<JsonElement>() {
@Override
public void onResponse(Call<JsonElement> call, Response<JsonElement> response) {
if(response.isSuccessful()){
JsonElement jsonElement = response.body();
JsonObject objectWhichYouNeed = jsonElement.getAsJsonObject();
//do whatever you want with Json Object. Deserialize it, get values by keys, get as String etc.
}
else{
System.out.println(response.message());
}
}
@Override
public void onFailure(Call<JsonElement> call, Throwable t) {
System.out.println("Failed");
}
});
