A friend asked me how the network request timed out. I didn't do this at the time, so I thought it was try .... catch... an error occurred while retrieving the result. I found that the result was not obtained. Today I have time to study it. I found that it was obtained from the object in the response, next I will share the entity of my own urlconnection and httpclient network request response code with you. I hope it will help you!
