四:python接口之http请求

python的强大之处在于提供了很多的标准库以及第三库,本文介绍urllib

和第三库的requests。

Urllib 定义了很多函数和类,这些函数和类能够帮助我们在复杂的情况下获取url内容。复杂情况— 基本的和深入的验证, 重定向, cookies 等等

Urllib的GET请求代码如下:

复制代码
import urllib.request

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

response=urllib.request.Request(url=url)

html=urllib.request.urlopen(response)

print(html.getcode())

print(html.headers)
复制代码

 

 

请求结果:

/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 /Users/playcrab/PycharmProjects/jiekouceshi/pachong.py

Urllib的Post请求,代码:

复制代码
import urllib.request

import urllib.parse

url='http://www.tuling123.com/openapi/api'

data={"key": "your", "info": '你好'}



data=urllib.parse.urlencode(data).encode('utf-8')

re=urllib.request.Request(url,data)

html=urllib.request.urlopen(re)



print(html.getcode(),html.msg)

print(html.read())
复制代码

 

 

结果:

/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 /Users/playcrab/PycharmProjects/jiekouceshi/pachong.py

200 OK

(注:这里不是乱码是输出格式的问题。)

下面介绍下requests库的http请求、

GET请求:

import requests

r = requests.get('https://www.baidu.com')

print(r.headers)

  }, 
  "json": null, 
  "origin": "180.87.10.156", 
  "url": "http://httpbin.org/post"

以上是利用urllib和requests发送GET和POST请求的事例。
