python的三种post请求

#!/user/bin/env python

# -*-coding: utf-8 -*-i

mport requests

import json

#rep=requests.request("get",url="https://postman-echo.com/get?fool=barl&foo2=bar2")

par={"fool":"barl","foo2":"bar2"}

rep=requests.get(url="https://postman-echo.com/get",params=par)
print(rep.content)

rep1=requests.get("https://postman-echo.com/get?fool=barl&foo2=bar2")
print(rep1.content)

data={"fool":"barl","foo2":"bar2"}
rep4=requests.post("https://postman-echo.com/post",data=data)
print(rep4.text)

rep2=requests.request("post",url="https://postman-echo.com/post?fool=barl&foo2=bar2",data="this is data")
print(rep2.content)
print(type(rep2.content))
rep3=requests.post("https://postman-echo.com/post?fool=barl&foo2=bar2")


#取响应数据中值的方法
print(rep3.content)
print(rep3.text)
print(type(rep3.text))
print(rep3.status_code)
print(rep3.headers)
print(rep3.json())
print(rep3.encoding)

#正确代码是把data进行json编码，再发送。代码如下：

#r = requests.post(url=url,data=json.dumps(data),headers=headers) # 利用 json 对 字典序列化

第一种是表单（application/x-www-form-urlencoded 以表单格式提交数据

data={"fool":"barl","foo2":"bar2"}

response=requests.post(url="https://postman-echo.com/post",data =data)

print(response.text)

data={"fool":"barl","foo2":"bar2"}

response=requests.post(url="https://postman-echo.com/post",data =data)

print(response.text)

第二种是json格式，-application/json

data={"fool":"barl","foo2":"bar2"}

response1=requests.post(url="https://postman-echo.com/post", json=data)

response2=requests.post(url="https://postman-echo.com/post", data=json.dumps(data))

data={"fool":"barl","foo2":"bar2"}

response1=requests.post(url="https://postman-echo.com/post", json=data)

response2=requests.post(url="https://postman-echo.com/post", data=json.dumps(data))

第三种是上传文件格式 -multipart/form-data

headers=""
files={"file":open("test_file.txt","rb")}
response3=requests.post("https://postman-echo.com/post",files=files,headers=headers)

print(response3.text)

headers=""

files={"file":open("test_file.txt","rb")}

response3=requests.post("https://postman-echo.com/post",files=files,headers=headers)

print(response3.text)

#备注： rb 代表以二进制读取数据 r 以人工书写读取数据
