将曲目添加到播放列表 SoundCloud API [英] Add track to playlist SoundCloud API

问题描述

在我的 Windows Phone 应用程序中，我使用以下代码向播放列表添加曲目(即对播放列表/id 端点的 PUT 请求)

In my Windows Phone App, I'm using the following code to add a track to playlist (i.e. a PUT request to playlists/id endpoint)

    using (HttpClient httpClient = new HttpClient())
            {
                httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(AccessToken);
                HttpResponseMessage response = await httpClient.PutAsync(endpoint, new StringContent(data));
                response.EnsureSuccessStatusCode();
            }

其中数据"是 JSON 数据的形式:

where "data" is JSON data the form:

    {"playlist":{"tracks":["TrackId(to be added)"]}}

以上代码返回OK"(200) 响应，但曲目未添加到播放列表中！

The above code returns "OK"(200) response but the track is NOT added to the playlist!

我做错了什么?卡了两天.提前致谢！

What am I doing wrong? Stuck on it for two days. Thanks in advance!

推荐答案

问题是 JSON 数据(请求正文的)格式不正确.数据"必须采用以下形式:

The problem was that the JSON data (of the request body) was not formatted correctly. "data" must be of the form:

    {"playlist":{"tracks":[{"id":"__"}, {"id":"__"}, {"id":"__"}]}}

此处必须存在 id-value 对

Here the id-value pair must be present for

• 播放列表中已经存在的每首曲目，以及

• every track already present in the playlist, as well as

要添加到播放列表的曲目

the track that you want to add to the playlist

(请记住，这是一个 PUT 请求.因此，您需要更新数据，即更新播放列表"的tracks"属性)

(Remember, this is a PUT request. So, you need to update data i.e. update the "tracks" property of the "playlist")
