It is often necessary to concatenate an array or List item into a string using a separator. The general implementation logic is to connect through members + delimiters, and then intercept the last Separator in the result. Suddenly, we found that the

In this article, we will take a big step forward by programming the server in asynchronous mode to make it a real server: Multiple client requests can be processed. But before we start, we need to solve a problem left over from the previous

1. Search for servers that support the qq http protocol.People may be confused by some counterfeits. They may think that QQ's HTTP Server communicates based on 80 ports (for example, 218.17.209.23: 80, the HTTP-based server should be:
