'Resource'对象没有属性'__getitem__' - Soundcloud Oembed

Question

我一直在尝试使用Soundcloud API嵌入音轨，但我一直在努力：

'资源'对象没有属性'__getitem __'

问题出在embed_info ['html']中，但我不知道如何修复它。

def downloadgate(request):
    # create a client object with your app credentials
    client = soundcloud.Client(client_id='Client_id')
    # get a tracks oembed data
    track_url = 'http://soundcloud.com/daomusic/preview'
    embed_info = client.get('/oembed', url=track_url)
    embed_info = embed_info['html']
    # print the html for the player widget
    return render(request, 'rango/downloadgate.html', {'embed_info' : embed_info})
