安装依赖
pip install requests
方式一：提交dict
该方式比较简单，可以直接提交json参数提交
# -*- coding: utf-8 -*- import requests url = 'http://httpbin.org/post' data = { 'name': 'Tom', 'age': 20 } res = requests.post(url, json=data) print(res.text)
返回数据
{ "args": {}, "data": "{\"name\": \"Tom\", \"age\": 20}", "files": {}, "form": {}, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Content-Length": "26", "Content-Type": "application/json", "Host": "httpbin.org", "User-Agent": "python-requests/2.28.1", "X-Amzn-Trace-Id": "Root=1-635f3812-432dff7a0625e9331bb8d78d" }, "json": { "age": 20, "name": "Tom" }, "origin": "1.202.253.34", "url": "http://httpbin.org/post" }
方式二：提交string
通过自定义请求体提交json数据
# -*- coding: utf-8 -*- import json import requests url = 'http://httpbin.org/post' data = { 'name': 'Tom', 'age': 20 } # 先序列化成json数据 data_raw = json.dumps(data) print(data_raw) # {"name": "Tom", "age": 20} res = requests.post(url, data=data_raw) print(res.text)
返回数据
{ "args": {}, "data": "{\"name\": \"Tom\", \"age\": 20}", "files": {}, "form": {}, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Content-Length": "26", "Host": "httpbin.org", "User-Agent": "python-requests/2.28.1", "X-Amzn-Trace-Id": "Root=1-635f38b0-37b9f6261c85922202d35ee8" }, "json": { "age": 20, "name": "Tom" }, "origin": "61.48.42.110", "url": "http://httpbin.org/post" }
进一步优化
我们可以发现，方式二提交的数据缺少了一个请求头
{ "Content-Type": "application/json" }
虽然可以识别为json数据，不过有的后端框架有可能不能够正常识别json数据
完善代码
# -*- coding: utf-8 -*- import json import requests url = 'http://httpbin.org/post' data = { 'name': 'Tom', 'age': 20 } # 先序列化成json数据 data_raw = json.dumps(data) print(data_raw) # {"name": "Tom", "age": 20} # 增加请求头 headers = { "Content-Type": "application/json; charset=UTF-8" } res = requests.post(url, data=data_raw, headers=headers) print(res.text)
返回数据
{ "args": {}, "data": "{\"name\": \"Tom\", \"age\": 20}", "files": {}, "form": {}, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Content-Length": "26", "Content-Type": "application/json; charset=UTF-8", "Host": "httpbin.org", "User-Agent": "python-requests/2.28.1", "X-Amzn-Trace-Id": "Root=1-635f3956-7d2bf56b737dd06278d54b80" }, "json": { "age": 20, "name": "Tom" }, "origin": "61.48.42.110", "url": "http://httpbin.org/post" }
