用python写一个爬取QQ音乐歌曲的爬虫

以下是一个简单的爬取QQ音乐的歌曲信息的Python爬虫：

import requests
from bs4 import BeautifulSoup

def get_songs(keyword):
    url = 'https://c.y.qq.com/soso/fcgi-bin/search_cp?'
    params = {
        'ct': '24',
        'qqmusic_ver': '1298',
        'new_json': '1',
        'remoteplace': 'sizer.yqq.song_next',
        'searchid': '64405487069162918',
        't': '0',
        'aggr': '1',
        'cr': '1',
        'catZhida': '1',
        'lossless': '0',
        'flag_qc': '0',
        'p': '1',
        'n': '20',
        'w': keyword,
        'g_tk_new_20200303': '5381',
        'g_tk': '5381',
        'loginUin': '0',
        'hostUin': '0',
        'format': 'json',
        'inCharset': 'utf8',
        'outCharset': 'utf-8',
        'notice': '0',
        'platform': 'yqq.json',
        'needNewCode': '0'
    }
    headers = {
        'referer': 'https://y.qq.com/portal/search.html',
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.82 Safari/537.36'
    }
    response = requests.get(url, params=params, headers=headers)
    if response.status_code == 200:
        data = response.json()
        song_list = data['data']['song']['list']
        for song in song_list:
            song_name = song['name']
            singer_name = song['singer'][0]['name']
            album_name = song['album']['name']
            print(f'Song Name: {song_name}, Singer: {singer_name}, Album: {album_name}')
    else:
        print('Failed to get songs.')

if __name__ == '__main__':
    keyword = input('Please enter the keyword: ')
    get_songs(keyword)

该爬虫使用了requests库和BeautifulSoup库，实现了自动搜索并爬取QQ音乐上关于指定歌曲的歌曲名、歌手名和专辑名，并输出到控制台。其中，url和params参数是通过分析QQ音乐搜索接口得到的，headers参数是通过在浏览器中查看请求头信息得到的。
