4. python request转为curl命令

从pyhthon导入一个叫curlify的库，可以完成转化

import curlify
import requests


data = {
    "wd": "hello"
}

url = 'http://www.baidu.com/s'

response = requests.get(url=url, data=data, headers={
    'Accept': 'text/html,application/xhtml+xml',
})

print(curlify.to_curl(response.request))

执行结果

$ python3 a.py
curl -X GET -H 'Accept: text/html,application/xhtml+xml' -H 'Accept-Encoding: gzip, deflate' -H 'Connection: keep-alive' -H 'Content-Length: 8' -H 'Content-Type: application/x-www-form-urlencoded' -H 'User-Agent: python-requests/2.25.1' -d wd=hello http://www.baidu.com/s
