http请求中的data&json

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import requests
import json

url = 'http://official-account/app/messages/group'
body = {"type": "text", "content": "测试文本", "tag_id": "20717"}
headers = {'content-type': "application/json"}

#print type(body)
#print type(json.dumps(body))
# 这里有个细节，如果body需要json形式的话，需要做处理
# 可以是data = json.dumps(body)
response = requests.post(url, data = json.dumps(body), headers = headers)
# 也可以直接将data字段换成json字段，2.4.3版本之后支持
# response = requests.post(url, json = body, headers = headers)

# 返回信息
print(response.text)
# 返回响应头
print(response.status_code)
