python - 尝试将歌曲添加到使用 spotify api 时收到 404

问题描述

我正在制作一个项目，它将从您的 youtube 播放列表中添加歌曲以识别播放列表。除add_item()方法外，一切正常。我得到了对象404 : not found的响应。requests

是的，我检查了这首歌是否真的存在。它确实，甚至打印了id这首歌。所以它存在。

我正在关注官方文档

这是我的代码 -

import json
from requests_oauthlib import OAuth2Session
import requests
import base64
import  urllib.parse as urlparse
from urllib.parse import parse_qs



client_id = #id
client_secret = #secret
redirect_uri = 'https://www.spotify.com'

        authorization_url, state = oauth.authorization_url(url)
        print(authorization_url)
        authorization_response = input('paste here : ')

        parsed = urlparse.urlparse(authorization_response)
        authorization_code = parse_qs(parsed.query)['code'][0]

        # to get auth token

            'type' : 'track',
            'limit' : 1,

        }

        search_response = requests.get(search_url, headers = headers, params = params)
        search_response.raise_for_status()
        
        json_response = search_response.json()
        song_uri =  json_response['tracks']['items'][0]['uri']
        self.uri_list.append(song_uri)
        
    def create_playlist(self) :

            'Content-Type' : 'application/json'
        }

        data = json.dumps({
            'name' : 'new playlist'
        })
        response = requests.post(create_playlist_url, headers = headers, data = data)
        print(response)
        self.playlist_id = response.json()['uri']

    def add_items(self) :
        add_items_url = f'https://api.spotify.com/v1/playlists/{self.playlist_id}/tracks'

        headers = {

        print(self.uri_list)
        data = {
            'uris' : json.dumps(self.uri_list)
        }

        res = requests.post(add_items_url, headers = headers, data = data)
        print(res)





user = sp()

user.create_playlist()
user.search()
user.add_items()

任何帮助表示赞赏。谢谢

解决方案

您有这行代码用于创建播放列表：

self.playlist_id = response.json()['uri']

然后在项目添加逻辑中你有：

add_items_url = f'https://api.spotify.com/v1/playlists/{self.playlist_id}/tracks'

您确定要使用播放列表 uri 作为播放列表 ID 吗？

您能否用更多信息更新您的问题：

  1. response.json()创建播放列表后的值
  2. add_items_url声明 f 字符串后打印

更新

https://developer.spotify.com/documentation/web-api/reference/playlists/create-playlist/我可以在这里看到 - 创建播放列表后的响应包括id字段

所以你应该改变这一行

self.playlist_id = response.json()['uri']

至

self.playlist_id = response.json()['id']
