Question

我正在使用tmdb来获取电视节目的详细信息。它具有一个如下所示的端点： https://api.themoviedb.org/3/tv/1399?api_key=API_KEY&append_to_response=season/1,season/2,season/3,season/4,season/5,season/6,season/7,season/8 在此，在响应后附加季节编号以在同一请求中提供该季节的详细信息。这是一个有8个季节的电视节目的例子。如果说2个季节，则终点为 https://api.themoviedb.org/3/tv/1399?api_key=API_KEY&append_to_response=season/1,season/2

现在，当创建用于处理此请求的模型类时，问题是季节本身作为对象而不是数组返回。所以可能会有很多季节。

{
    "id": ...,
    ...,
    ...,
    "season/1": {...},
    "season/2": {...},
    "season/3": {...}
}

这些季节中的每个季节都需要一个新的模型类，并且对象的数量也是可变的。我该如何处理？

Request with 8 seasons

Request with 3 seasons

The simplest solution for this is just to define your response to be of type ResponseBody which looks like this:

@GET(value = "/{yourFirstNumber}/tv/{yourSecondNumber}")
Call<ResponseBody> getStuff(@Path("yourFirstNumber") String whateverYouWantToNameThis1,
                            @Path("yourSecondNumber") String whateverYouWantToNameThis2,
                            @Query("api_key") String apiKey,
                            @Query("append_to_response") String appendToResponse);

Just make sure you name these number variables to what they are instead of the phrasing I used as I am unfamiliar with the API.

With this, your request call will look like this:

Call<ResponseBody> call = yourService.getStuff(yourObject);
call.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                L.m("RESPONSE CODE == " + response.code());
                if(response.isSuccessful()){
                    ResponseBody successResponse = response.body();
                    //This means it was successful (IE a 200)
                } else {
                    ResponseBody errorResponse = response.errorBody();
                    //This means there was an error (IE a 402)
                }
            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                //Handle your error here
            }
        });

From there you can parse your successResponse in multiple different ways.

For example I use GSON and a few other methods in this class, but it really depends on how you want to parse it. If you want to convert it into a string, use the successResponse.string() (not a typo, make sure to use string() and not toString() ) method and convert it from the serialized response into one you can easily use.

在运行时需要为改造模型声明多个对象
