python - 从 lastfm : TypeError: string indices must be integers 获取轨道的 mbid

Question

我有轨道{}，它使用最新的 fm API 存储有关轨道的一些信息。现在我想将每个轨道的 mbid 存储在 Tracks{} 中，但出现错误:

  mbid = track['mbid']
TypeError: string indices must be integers

print(track) 返回:

name
mbid
url
duration
....

print(track_mbid_response) 具有以下格式:

{'track': {'name': 'Achtung Baby', 'mbid'.....: 

你知道问题出在哪里吗？

for i, v in tracks.items():
    artist = tracks[i]['artist'].replace(" ", "+")
    title = tracks[i]['title'].replace(" ", "+")


    track_mbid =  requests.get('http://ws.audioscrobbler.com/2.0/?method=track.getInfo&format=json&api_key=' + api_key + '&artist=' + artist + '&track=' + title)
    track_mbid_response = track_mbid.json()

    #print(track_mbid_response)

    for track in track_mbid_response['track']:
        #print(track)

        mbid = track['mbid']
        print(mbid)

        tracks[ID]['mbid'] = tracks[i]['mbid']

Answer 1

您正在迭代轨道中的键。只需执行 track = track_mbid_response["track"] 然后您就可以添加到该字典中。
