This article mainly explains "how Android uses WeCom to achieve monitoring notification". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how Android uses WeCom to achieve monitoring notification".

Create an application

Accounts that do not verify subject information can only have 200 members, and the number of times sent is limited to: the maximum number of accounts * 30 person-times per day

After registration, you can go to the background management page, and click apply Management.

Before we start to call the API of the official account, we need to create an application where alerts can be sent to the specified application. At the same time, we can authorize the application to limit the range of people who can see the alarm.

After the creation is complete, click the application icon to see the following page

The AgentId and Secret fields will be used later in the code.

Wechat API

To achieve simple message delivery, we only need to use two Wechat API interfaces

Get token: https://work.weixin.qq.com/api/doc#10013

Send message: https://work.weixin.qq.com/api/doc#10167

Code implementation #-*-coding:utf-8-*-import jsonimport requestsclass WeChatPub (): def _ _ init__ (self,corpid='wwb1b',secret='tnbqWD0'): self.req = requests.session () self.token = self.get_token (corpid, secret) print ("token is" + self.token) def get_token (self,corpid Secret): url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={0}&corpsecret={1}".format(corpid, secret) response = self.req.get (url) if response.status_code = 200: access_token=json.loads (response.content) ['access_token'] return access_token else: print (" request failed.

Encode ('utf-8') rep = self.req.post (url, data=data, headers=header) if rep.status_code = 200: return json.loads (rep.content) else: print ("request failed.") Return Noneif _ _ name__ = ='_ main__': wechat = WeChatPub () msg=''' July 26th, 2020 Congratulations on your selection of iPhone 7, award code: xxxx, please contact your administrative colleagues to get the''wechat.send_msg (msg) corpid before October 10, 2020.

Each enterprise has a unique corpid. To obtain this information, you can view the "enterprise ID" under "my Enterprise"-"Enterprise Information" in the management background (administrator permission is required).

Access_token

Access_token is the global unique ticket of the official account, which needs to use access_token when calling each interface.

Developers need to cache access_token for subsequent API calls (Note: the gettoken API should not be called frequently, otherwise it will be blocked by frequency). When the access_token expires or expires, it needs to be reacquired.

The validity period of access_token is communicated through the returned expires_in, which is normally 7200 seconds (2 hours). The same result will be returned after repeated acquisition within the validity period, and a new access_token will be returned when it expires.

Since the access_token of each application of WeCom is independent of each other, you need to distinguish between applications for storage when caching.

Access_token reserves at least 512 bytes of storage space.

WeCom may invalidate access_token ahead of time for operational needs, and developers should implement the logic of retrieving access_token when it fails.
