Spotify Web API-创建播放列表时没有正文的错误400

spotify python-requests python-3.x python

我正在尝试使用Spotify Web API创建和填充播放列表。我在跟踪 this 官方参考,我将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函数是处理ratelimiting的requests.request的包装器。

上面的代码在第一次调用makeRequest时用一堆样本跟踪运行时返回一个错误400,因此我的样本跟踪不能成为问题,因为只有名称和公共变量与该调用有关。

错误响应没有正文,因此没有错误描述。这表明我可能遗漏了一些非常明显的东西。有人能帮忙吗?

播放列表创建请求停止出错,我不知道原因。当我试图诊断这个问题时,我必须改变任何错误。我以为它试图创建一个同名的播放列表,但spotify允许重复播放列表。可能我使用的令牌或令牌对象有问题。对不起的。

但是,在清除前一个问题时,我还发现了另一个问题:添加到曲目时,指定的是曲目uri(spotify:track:abcdef123),而不仅仅是曲目id(abcdef123)。我修改了spotify的以下播放列表:

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
