import requests

 

下面就可以使用神奇的requests模块了!

 

1.向网页发送数据

>>> payload = {key1: value1, key2: [value2, value3]}>>> r = requests.get(http://httpbin.org/get, params=payload)>>> print(r.url)http://httpbin.org/get?key1=value1&key2=value2&key2=value3

  post与get方法都类似,只不过不是params=...而是data=http://www.mamicode.com/...

>>> r = requests.put("http://httpbin.org/put")>>> r = requests.delete("http://httpbin.org/delete")>>> r = requests.head("http://httpbin.org/get")>>> r = requests.options("http://httpbin.org/get")

2.把Response保存到文件里(官方文档推荐的方法)

with open(filename, wb) as fd:    for chunk in r.iter_content(chunk_size):        fd.write(chunk)

3. r的一些属性

  r.encoding  #编码

  r.status_code  #状态码(404,200等)

  r.raise_for_status()  #如果状态码不是200会发起报错

4.高级用法(会话对象——仿真网页操作):http://cn.python-requests.org/zh_CN/latest/user/advanced.html#advanced
