python爬虫qq音乐评论

你可以使用Python的requests库和正则表达式来爬取QQ音乐的评论。以下是一个简单的示例代码：

import requests
import re

url = "https://c.y.qq.com/base/fcgi-bin/fcg_global_comment_h5.fcg"
headers = {
    "referer": "https://y.qq.com/n/yqq/song/0039MnYb0qxYhV.html",
    "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"
}
params = {
    "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": "212877816",
    "cmd": "8",
    "pagenum": "0",
    "pagesize": "25",
    "lasthotcommentid": "",
    "domain": "qq.com",
    "ct": "24",
    "cv": "10101010"
}

response = requests.get(url, headers=headers, params=params)
comments = re.findall(r'"content":"(.*?)"', response.text)

for comment in comments:
    print(comment)

在以上代码中，我们首先指定了要爬取的QQ音乐歌曲的评论页链接，然后设置了请求头和请求参数。最后，我们使用requests库发送GET请求，并使用正则表达式提取评论内容。最后，我们打印所有评论。
