Python爬虫学习

一、

爬虫：代码模拟浏览器向服务器发送请求并得到目标数据。

二、

1.get请求

import requests

query = input("请输入你想查询的内容：")
url = f"https://www.sogou.com/web?query={query}"

header = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3100.0 Safari/537.36"
}

res = requests.get(url, headers=header)

print(res)
print(res.request)
print(res.encoding)

with open('sougou.html', mode="w", encoding='utf-8') as f:
    f.write(res.text)
    f.close()

2.post请求

import requests

url = "https://fanyi.baidu.com/sug"

s = input('请输入您想查询的单词:')

da = {
    'kw': s
}

res = requests.post(url, data=da)
res.close()
res = res.json()

print(res['data'][0]['k']+'的中文翻译为为：')
print(res['data'][0]['v'])
