Managing Message Access in Applications
Huawei Cloud Astro Zero's message access function enables swift creation of data access rules and event standardization. Message access is packaged and released in the development environment and then synchronized to the runtime environment. In the runtime environment, you can only modify the access data but cannot create data access. For details about how to create a message access, see Integrating Message Data into Huawei Cloud Astro Zero Through the Data Access Function.
