1、安装

pip install requests

2、get请求

如果需要加cookie可以直接加在headers中

import requests#get请求带参数url="http://xxx/api/user/stu_info"data={
   "stu_name":"矿泉水1"}result=requests.get(url,data)print(result.json()) #返回字典类型print(result.text) #返回一个字符串类型print(result.content) #返回bytes类型#get请求无参数url2='http://q4.qlogo.cn/g?b=qq&nk=xxx&s=140'result2=requests.get(url2)fw=open("jjj.png",'wb') #get请求结果写入文件fw.write(result2.content)fw.close()

 3、post 请求

 

1、传入xml格式文本requests.post(url='',data='
     ',headers={
   'Content-Type':'text/xml'})2、传入json格式文本requests.post(url='',data=json.dumps({
   'key1':'value1','key2':'value2'}),headers={
   'Content-Type':'application/json'})或者：requests.post(url='',json={
   {
   'key1':'value1','key2':'value2'}},headers={
   'Content-Type':'application/json'}3、请求正文是multipart/form-data除了传统的application/x-www-form-urlencoded表单，我们另一个经常用到的是上传文件用的表单，这种表单的类型为multipart/form-datarequests.post(url='',data={
   'key1':'value1','key2':'value2'},headers={
   'Content-Type':'multipart/form-data'})4、请求正文是application/x-www-form-urlencoded 默认就是这种，可以不标注headers的值requests.post(url='',data={
   'key1':'value1','key2':'value2'},headers={
   'Content-Type':'application/x-www-form-urlencoded'})
