Unity learning socket (1)

I wrote a blog for writing. No matter the quality, I had to clean it up.

I feel so sad to myself. I have never done online games before I went out for an internship, and I almost didn't use socket. So now I have nothing to do at school. I have to learn more about network communication and so on. Let's start from scratch. The first example below is very simple. Don't laugh at me. In this example, we use the TCP protocol of socket. Of course we can also use UDP and tcplistener. I didn't use multithreading. Oh, it's just to look at some functions in it.

Server. CS:

Using unityengine; using system. collections; using system. net; using system. io; using system. net. sockets; using system. text; public class server: monobehaviour {void start () {openserver ();} void openserver () {IPaddress ipadr = IPaddress. parse ("10.56.03.32"); ipendpoint ipep = new ipendpoint (ipadr, 1234); socket serverscoket = new socket (addressfamily. interNetwork, sockettype. stream, protocoltype. TCP); serve Rscoket. BIND (ipep); serverscoket. listen (20); While (true) {Socket Client = serverscoket. accept (); byte [] request = new byte [512]; int bytesread = client. receive (request); string input = encoding. utf8.getstring (request, 0, bytesread); print ("Server Request:" + input); string output = "successfully connected to the server ~~~~ "; Byte [] concent = encoding. utf8.getbytes (output); client. Send (concent); client. Shutdown (socketshutdown. Both); client. Close ();}}}

 

 

Client. CS:

Using unityengine; using system. collections; using system. text; using system. net; using system. net. sockets; using system. io; public class client: monobehaviour {void start () {conncetserver ();} void conncetserver () {IPaddress ipadr = IPaddress. parse ("10.56.03.32"); ipendpoint ipep = new ipendpoint (ipadr, 1234); socket clientscoket = new socket (addressfamily. interNetwork, sockettype. stream, protocoltype. TCP) ; Clientscoket. Connect (ipep); string output = "client request connection ~~~ "; Byte [] concent = encoding. utf8.getbytes (output); clientscoket. send (concent); byte [] response = new byte [1024]; int bytesread = clientscoket. receive (response); string input = encoding. utf8.getstring (response, 0, bytesread); print ("client request:" + input); clientscoket. shutdown (socketshutdown. both); clientscoket. close ();}}

Server:

1). Use SOCKET () to obtain a socket description

2). BIND () J to bind the socket to a network address (generally the local IP address)

3) Use listen () to start listening on a port

4). Accept () waits for the client to connect. If the client calls the connect () function to connect to the server, accept () will obtain the client (socket ).

5). Receive () receives data

6). Send () to send data

 

 

Client:

1). Use SOCKET () to obtain a socket description

2) connect () to a remote host

3). Send () to send data

4). Receive () receives data
