项目目标

• 爬取歌曲的精彩评论
• 爬取被隐藏的歌曲清单

get精彩评论：

import requests

for i in range(5):
    res_comments = requests.get('https://c.y.qq.com/base/fcgi-bin/fcg_global_comment_h5.fcg?g_tk=5381&loginUin=0&hostUin=0&format=json&inCharset=utf8&outCharset=GB2312&notice=0&platform=yqq.json&needNewCode=0&cid=205360772&reqtype=2&biztype=1&topid=102065756&cmd=6&needmusiccrit=0&pagenum='+str(i)+'&pagesize=15&lasthotcommentid=song_102065756_3202544866_44059185&domain=qq.com&ct=24&cv=10101010')
    # 调用get方法，下载评论列表
    json_comments = res_comments.json()
    # 使用json()方法，将response对象，转为列表/字典
    list_comments = json_comments['comment']['commentlist']
    # 一层一层地取字典，获取评论列表
    for comment in list_comments:

        print(comment['rootcommentcontent'])
        # 输出评论
        print('-----------------------------------')
        # 将不同的评论分隔开来
