Question

我正在尝试使用Spotify Web API创建并填充播放列表。我正在遵循this官方参考，并且正在将Python 3与requests模块一起使用。这是我的代码：

def spotify_write_playlist(auth, name, tracks, public=True):
    ids = []
    for track in tracks:
        track_id = track.services['spotify']
        if track_id: ids.append(track_id)
    headers = {
        "authorization":"Bearer " + auth.token,
        "content-type":"application/json"
    }
    data = {
        "name":name,
        "public":public
    }
    r = makeRequest("https://api.spotify.com/v1/users/" + auth.username + "/playlists", "post", 201, json=data, headers=headers)
    playlist_id = json.loads(r.content)['id']
    data = {"uris":ids}
    r = makeRequest("https://api.spotify.com/v1/users/" + auth.username + "/playlists/" + playlist_id + "/tracks", "post", 201, json=data, headers=headers)
    return playlist_id

def makeRequest(url, method="get", expectedCode=200, *args, **kwargs):
    while True:
        r = requests.request(method, url, **kwargs)
        if r.status_code == 429:
            time.sleep(TMR_DELAY)
            continue
        elif r.status_code == expectedCode:
            return r
        else:
            if "spotify.com" in url:
                raise spotify.ApiError(r.status_code, expectedCode, r.content)
            else:
                raise youtube.ApiError(r.status_code, expectedCode, r.content)

makeRequest函数是用于处理速率限制的request.request的包装。

上面的代码与一堆示例轨道一起运行时，在第一次调用makeRequest时返回错误400，因此我的示例轨道不会成为问题，因为该调用只涉及名称和公共变量。

错误响应没有正文，因此没有错误描述。这表明我可能缺少一些非常明显的东西。有人可以帮忙吗？

Answer 1

播放列表创建请求停止了错误，我不知道为什么。在尝试诊断问题时，我必须更改所有错误。我以为它试图创建一个同名的播放列表，但Spotify允许重复的播放列表。也许我使用的令牌或令牌对象有问题。抱歉。

但是，当清除上一个时，我还发现了另一个问题：在添加到轨道中时，您不仅指定了轨道ID（abcdef123），还指定了轨道uri（spotify：track：abcdef123）。我修改了以下的Spotify_write_playlists：

def spotify_write_playlist(auth, name, tracks, public=True):
ids = []
for track in tracks:
    track_id = track.services['spotify']
    if track_id: ids.append("spotify:track:"+track_id)
headers = {
    "authorization":"Bearer " + auth.token,
    "content-type":"application/json"
}
data = {
    "name":name,
    "public":public
}
r = makeRequest("https://api.spotify.com/v1/users/" + auth.username + "/playlists", "post", 201, json=data, headers=headers)
playlist_id = json.loads(r.content)['id']
data = {"uris":ids}
r = makeRequest("https://api.spotify.com/v1/users/" + auth.username + "/playlists/" + playlist_id + "/tracks", "post", 201, json=data, headers=headers)
return playlist_id

Spotify Web API-错误400，播放列表创建无内容
