Solve the socket security policy file problem of Flash AS3 with Golang

This is a creation in Article, where the information may have evolved or changed.

The code is as follows:

</pre><pre>package mainimport ("Bufio" "FMT" "NET" "OS" "Time") const (Head = 4) var (clientmap map[int]net. Conn = Make (map[int]net. Conn)) Func main () {FMT. Println (OS. Args[0]) Ip_port: = "127.0.0.1:843" If Len (OS. Args) > 1 {ip_port = OS. Args[1]}fmt. Println ("\nflash as policy service running ... \ n" automatically responds to crossdomain.xml requests for socketxml ports (i.e. 843 ports) \ n to specify the IP and port, you can specify the parameters when the program starts, in the following format \ Ngameserver843.exe 192.168.101.139:843 "," \ n currently listening ", Ip_port," \ n please do not close this window ...

Install the Golang environment, then go directly to run Main.go on the line.

Of course, you can also download my compiled exe executable file directly.
