添加曲目到播放列表的SoundCloud API [英] Add track to playlist SoundCloud API

问题描述

在我的Windows Phone应用程序，我用下面的code到A曲目添加到播放列表（即PUT请求到播放列表/ ID端点）

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数据的格式为：

where "data" is JSON data the form:

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

以上code返回OK（200）响应，但在赛道不添加到播放列表中！

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

我是什么做错了吗？粘贴了两天。在此先感谢！

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

推荐答案

的问题是，（请求体）的JSON数据的格式不正确。
数据的形式必须的：

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":"__"}]}}

下面的ID值对必须是present

Here the id-value pair must be present for

• 每个轨道已经present播放列表，以及

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

要添加到播放列表曲目

（请记住，这是一个PUT请求。所以，你需要更新数据，即更新轨迹中的播放列表的属性）

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