Wechat official account development: Material Management (temporary and permanent)
2022-07-24 12:06:00 【Don't wear perfume】
List of articles
explain
This article is for reference only , But make sure the code is available
Please check first Official website material management
1、 Description of the material on the official website 
2. Upload the description of the interface 
Actually measured Temporary material interface File parameter name in media You can use non fixed parameter names , Change to as file Parameter names like can still be uploaded successfully
3.access_token
Reference resources ： Wechat official account news push development （ Template message ）： The development of implementation ( Two )
Code implementation
1. The code shown below is not an interface , You can modify 2. Yes voice When judging the type of file , Time length is not checked , Please make your own judgment 3. The following pictures are used as demonstration materials 4 Use httpclient Simulation of the request

The temporary file is uploaded successfully and returned media_id
2. Get temporary material
After the temporary material is obtained, it is a file stream , If it is played directly in the browser, it will be downloaded directly to the local
https://api.weixin.qq.com/cgi-bin/media/get?access_token=ACCESS_TOKEN&media_id=MEDIA_ID
take Add temporary material Example modification
Use the above media_id

Perform rear console output
It can be seen that the output is a file stream , If it is used for front-end echo , Need to transform , If you access it directly in the browser , Will download directly , The official website also gives instructions 
Browser access effect 
3. Add permanent material
The main difference with temporary materials ：
1. Know what you know , There is no such thing as expiration , Will not automatically delete
2. The supported material formats are also different , See the official website for details There are two interfaces for uploading permanent materials , You can choose according to your own needs , The following is a brief demonstration based on two interfaces
1. Image acquisition in uploaded text message URL
The benefits of using have been officially explained ：
People don't talk too much

Check the console after execution 
Returned a url Check the material library , It is not found that the uploaded file is in the material library 
2. Add other types of permanent materials
1. The process is the same as that of uploading new temporary materials , The material format is slightly different from that of temporary material 2. When uploading video material in this example , Please modify according to the official requirements , Just pass the corresponding parameters 
No more beeps
