requests--基于http协议的网络库

测试网站：http://httpbin.org

http协议两大请求：get/post

导包：

      import requests

      import json

例子：

#不带参get请求
r=requests.get("http://httpbin.org/get")

#带参get请求
myParams={"username":"test","password":"12345"}
r=requests.get("http://httpbin.org/get",params=myParams)

#不带参post请求
r=requests.post("http://httpbin.org/post")

#带参post请求
myData={"username":"test","password":"123456"}
r=requests.post("http://httpbin.org/post",data=myData)

#提交json数据的post请求
myData={"username":"test","password":"123456"}
r=requests.post("http://httpbin.org/post",data=json.dumps(myData))

#通过post请求提交图片
myfile={"file1":open("C:\Users\clareliu\Desktop\1.png","rb")}
r=requests.post("http://httpbin.org/post",files=myfile)

#建立会话后,通过会话发送get/post请求
s=requests.Session()
#get请求
r=s.get("http://httpbin.org/get")
#post请求
r=s.post("http://httpbin.org/post")
