python输入歌曲名称下载网易云音乐代码

在Python中，为了从网易云音乐下载歌曲，你需要使用第三方库如`pyecharts`或`requests`等。这里提供一个基本的示例，使用`spotipy`库来搜索并下载歌曲，但请注意这可能涉及到版权问题，仅供学习参考：

from spotipy.oauth2 import SpotifyOAuth
import spotipy
import os

# 获取Spotify API的客户端ID、client secret和redirect URI
SPOTIFY_CLIENT_ID = 'your_client_id'
SPOTIFY_CLIENT_SECRET = 'your_client_secret'
REDIRECT_URI = 'http://localhost:8080/callback'

# 设置授权信息
scope = 'user-library-read user-read-private playlist-modify-public'
sp = spotipy.Spotify(auth_manager=SpotifyOAuth(client_id=SPOTIFY_CLIENT_ID,
                                               client_secret=SPOTIFY_CLIENT_SECRET,
                                               redirect_uri=REDIRECT_URI,
                                               scope=scope))

def download_song(song_name):
    # 搜索歌曲名
    results = sp.search(q=song_name, type='track')
    if results['tracks']['total'] > 0:
        track = results['tracks']['items'][0]  # 取第一个结果
        song_url = track['external_urls']['m4a']  # 获取M4A格式的下载链接

        # 下载文件
        file_name = f"{song_name}.m4a"
        response = requests.get(song_url, stream=True)
        with open(file_name, 'wb') as f:
            for chunk in response.iter_content(chunk_size=1024):
                if chunk:  # filter out keep-alive new chunks
                    f.write(chunk)

        print(f"歌曲 '{song_name}' 已成功下载到本地.")
    else:
        print(f"未找到匹配的歌曲'{song_name}'.")

# 使用函数下载歌曲，例如，歌曲名为 "Lose You To Love Me"
download_song("Lose You To Love Me")
