Requests

Requests官网文档

安装

pip install requests

使用

• import requests
• from requests import Session

重写requests

class MySession(Session):
    def request(self, method, url, *args, **kwargs):
        url = 'http://www.baidu.com/api' + url
        resp = super(MySession, self).request(
            method, url,  *args, **kwargs
        )
        return resp
        
req = MySession()
req.headers = {"Accept": "application/json",}

发送GET请求

req.get('address')

发送POST请求

req.post('login',json={"account":"test","password":"123456"})

发送multipart/form-data 请求

参考：使用python的requests 发送multipart/form-data 请求

一个multipart/form-data 的表单数据，在http里面抓包如下：

------WebKitFormBoundaryVC8tladcocNyAE7v
Content-Disposition: form-data; name="file";
filename="test.csv"
Content-Type: application/vnd.ms-excel
------WebKitFormBoundaryVC8tladcocNyAE7v
Content-Disposition: form-data;
name="test_id" 123
------WebKitFormBoundaryVC8tladcocNyAE7v
Content-Disposition: form-data; name="name" test
------WebKitFormBoundaryVC8tladcocNyAE7v

上述数据在requests请求里面可以模拟为:

     data1={
       "file":('test.csv',open('文件路径','rb'),'application/vnd.ms-excel'),
       "test_id": (None,"123"),
       "name":(None, "1"),
     } 

    header1 = {
      "Content-Type":"multipart/form-data; boundary=----WebKitFormBoundaryVC8tladcocNyAE7v"
      }

     response=req.post(url,files=files,header=header1)

获取请求响应信息

resp.request.url  请求url
resp.json() 响应结果
resp.request.body 请求体
resp.request.headers 请求头
