[Communication] Be careful to write try catch outside of while! and write return in while!

I had a problem today, which is to do http listening services.

There was a mistake, and I don't even know where it was.

The first time I sent a request, I responded, and then there was no response, and the power was cut off, and I didn't know what the problem was.

It turns out that there is an abnormality in the accepted data, and then it will enter the catch, and then it will jump out of the while loop!!!


Then, I also wrote a return in while, and return jumped out of the method! ! Then I don't go through the while cycle...

Two details, please pay attention!
