python 标准库 -- requests

一. 安装

$ pip install requests

requests 并不是python 标准库, 但为了汇总方便, 将其放置于此.

二. 用法

requests.get() : GET 请求

payload = {'key1': 'value1', 'key2': 'value2'}
ret = requests.get('http://www.example.com', params=payload)
ret.url     # 访问的 url
ret.text    # 访问结果
ret.content
ret.cookis
ret.headers
ret.json
ret.status_code
ret.ok

requests.post() : POST 请求

import requests
import json
url = 'http://httpbin.org/post'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}
ret = requests.post(url, data=json.dumps(payload), headers=headers)
print(ret.text)
print(ret.cookies)    

其他方法 :

requests.get(url, params=None, **kwargs)
requests.post(url, data=None, json=None, **kwargs)
requests.put(url, data=None, **kwargs)
requests.head(url, **kwargs)
requests.delete(url, **kwargs)
requests.patch(url, data=None, **kwargs)
requests.options(url, **kwargs)
# 以上方法都是在 此方法的基础上构建的
requests.request(method, url, **kwargs)
