Requests module 사용하기

Requests

Requests allows you to send organic, grass-fed HTTP/1.1 requests, without the need for manual labor. There's no need to manually add query strings to your URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling are 100% automatic, thanks to urllib3.

Simple usage

Postman(HTTP Request composer)에서 언급되었던 http://httpbin.org사이트를 이용해서 한번 request의 응답을 받아보자.

import requests payload = {'key':'testkey', 'apply_type':'requests test'} res = requests.post('http://httpbin.org/anything', data=payload) print(res.text)

실행하면 아래와 같이 응답이 오는 것을 확인 할 수 있습니다.

{ "args": {}, "data": "", "files": {}, "form": { "apply_type": "requests test", "key": "testkey" }, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Connection": "close", "Content-Length": "36", "Content-Type": "application/x-www-form-urlencoded", "Host": "httpbin.org", "User-Agent": "python-requests/2.18.4" }, "json": null, "method": "GET", "origin": "116.34.23.18", "url": "http://httpbin.org/anything" } Process finished with exit code 0
