Setting is useless because the server is disconnected if no data is received within five seconds.

I want to set the timeout for capturing remote data to less than 5 s, for example, 2 s. If the time for capturing remote data exceeds the timeout value. Make a fault tolerance process, because if you do not spit out the information within five seconds, the user will not receive anything.

Write asynchronous call. Upon receiving the message, the system immediately responds, Asynchronously processes the specific logic, and then sends feedback through the customer service message.
