微信公众号推送文字消息与模板消息

要实现对微信公众好粉丝消息的推送，首先要知道推送粉丝的openid，然后根据openid向粉丝推送消息。
支持多种类型，包括一段文字，也包括有结构的模板消息。

1、必要信息

需要用户先关注公众号
首先要查询到公众号的appid、secret信息
如果发送模板消息，还需要查询模板id：templete_id
并设置模板：

字段1 {{string1.DATA}}
字段2 {{string2.DATA}}
字段3 {{string3.DATA}}

2、openid的获取

def get_access_token(appid, secret):url = f"https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={appid}&secret={secret}"response = requests.get(url)return response.json()['access_token']## 获取要推送用户的openid
def get_openid():next_openid = ''  # 第一个拉取的OPENID，不填默认从头开始拉取 ，一次只能获取10000条url_openid = 'https://api.weixin.qq.com/cgi-bin/user/get?access_token=%s&next_openid=%s' % (get_access_token(appid, secret), next_openid)ans = requests.get(url_openid)openid = json.loads(ans.content)['data']['openid']return openid

3、推送文字消息

def send_text_message(access_token, openid, content):url = f"https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={access_token}"text_message = {"touser": openid,"template_id": template_id,"url": "用户点击后的跳转链接","data": {"content": "1"}}response = requests.post(url, json=text_message)return response.json()

4、推送模板消息

def send_template_message(openid, content):print(content)client = WeChatClient(appid, secret)template_message = {"user_id": openid,"template_id": template_id,"url": "访问链接","data": {"string1": {"value": "string1","color": "#173177"},"string2": {"value": "string2","color": "#173177"},"string3": {"value": "string3","color": "#173177"}}}try:res = client.message.send_template(**template_message)print("✅ 模板消息发送成功！")print("返回结果：", res)return resexcept WeChatException as e:print("❌ 模板消息发送失败！")print("错误码：", e.errcode)print("错误信息：", e.errmsg)

5、代码实现

整体代码实现逻辑

appid = "替换"
secret = "替换"
template_id="替换"
def get_access_token(appid, secret):url = f"https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={appid}&secret={secret}"response = requests.get(url)return response.json()['access_token']## 获取要推送用户的openid
def get_openid():next_openid = ''  # 第一个拉取的OPENID，不填默认从头开始拉取 ，一次只能获取10000条url_openid = 'https://api.weixin.qq.com/cgi-bin/user/get?access_token=%s&next_openid=%s' % (get_access_token(appid, secret), next_openid)ans = requests.get(url_openid)openid = json.loads(ans.content)['data']['openid']return openiddef send_text_message(access_token, openid, content):url = f"https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={access_token}"text_message = {"touser": openid,"template_id": template_id,"url": "用户点击后的跳转链接","data": {"content": "1"}}response = requests.post(url, json=text_message)return response.json()def send_template_message(openid, content):print(content)client = WeChatClient(appid, secret)template_message = {"user_id": openid,"template_id": template_id,"url": "url","data": {"string1": {"value": "string3","color": "#173177"},"string2": {"value": "string3","color": "#173177"},"string3": {"value": "string3","color": "#173177"}}}try:res = client.message.send_template(**template_message)print("✅ 模板消息发送成功！")print("返回结果：", res)return resexcept WeChatException as e:print("❌ 模板消息发送失败！")print("错误码：", e.errcode)print("错误信息：", e.errmsg)#推送到微信公众号
def sendmes(msg):openid = get_openid()# 发送模板result = send_template_message(openid, msg)# 发送文字#access_token = get_access_token(appid, secret)#result = send_text_message(access_token, openid[0], msg)print(result)
