我阅读了犇犇犇犇的关于爬虫的日报，存在疑问，如下： 我发现犇犇犇犇的界面 与我的存在不同 我试着尝试使用我的，但发现： sign:。每次请求会变化，且使用不成功。

我的代码如下

import requests
url = "https://dict.youdao.com/webtranslate" 
data = {
    "i": "hello world",
    "from": "AUTO",
    "to": "",
    "domain": "0",
    "dictResult": "true",
    "keyid": "webfanyi",
    "sign": "1e53f7d1123a422d86ca7b7245b95673",
    "client": "fanyideskweb",
    "product": "webfanyi",
    "appVersion": "1.0.0",
    "vendor": "web",
    "pointParam": "client,mysticTime,product",
    "mysticTime": "1683200378512",
    "keyfrom": "fanyi.web"
} 
head = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36"} # 把浏览器的User-Agent贴进来，这里head也是一个字典
response = requests.post(url=url,data=data,headers=head)
print(response.text)
