代码示例:
# 发送post请求 import requests,json # 发送post请求的基础知识dumps和loads str_dict ={'name':'xiaoming','age':'20','sex':'男'} print(type(str_dict)) str1 = json.dumps(str_dict) # 1,json.dumps 是把字典、json对象转换为字符串 print(type(str1)) print(str1) str2 = '{"name":"tom","age":"22","sex":"男"}' # 注意 这里是字符串,里面必须用双引号 str_json = json.loads(str2) # 2,json.loads 是将字符串转成字典,json对象 print(type(str_json)) print(str_json['name'],str_json.get('age'))
发送post请求
# 1,获取token url = 'https://api.weixin.qq.com/cgi-bin/token' data = {'grant_type':'client_credential', 'appid':'wxf14419077f707', 'secret':'92a113bd4b5ffdc72144740dc7123'} response = requests.get(url=url,params=data) # 响应是str类型 ,所以我们需要将响应转换成json json_obj = response.json() token = json_obj['access_token'] print(token) # 2,新建用户标签 tag_url = 'https://api.weixin.qq.com/cgi-bin/tags/create' tag_data = {'access_token':token} tag_json_body = {"tag":{"name" :"长沙01"} } headers = {"content-type":"application/json"} # 发送json 数据必须带有头部信息 content-type # post请求中body中的参数通过data,json 传递 # 如果body中的数据为json格式,在发送时可以直接使用json=body值 # response = requests.post(url=tag_url,params=tag_data,headers=headers,json=tag_json_body) # 如果body中的数据为json格式,在发送时使用data=json.dumps(body值) response = requests.post(url=tag_url,params=tag_data,headers=headers,data=json.dumps(tag_json_body)) print(response.content.decode("utf-8"))

代码示例:
# 封装post方法 def send_post(url,data,json_info): headers = {"content-type": "application/json"} response = requests.post(url=url,params=data,json=json_info,headers=headers) return response print(send_post(url=tag_url,data=tag_data,json_info=tag_json).content.decode("utf-8"))
代码示例:

光学理论是没用的,要学会跟着一起敲,要动手实操,才能将自己的所学运用到实际当中去,这时候可以搞点实战案例来学习。
