# aardio 范例: 服务端



```aardio
import console;
import wsock.tcp.server;

var tcpServer = wsock.tcp.server("127.0.0.1",7510)
 
console.log("服务端已启动")
tcpServer.forever(
	function(acceptSocket){
	
		var client = wsock.tcp.client(,acceptSocket);
		
		import fsys.dlg;  
		var fpath = fsys.dlg.open( , "客户端连接成功,请选择文件然后开始发送");
		if( fpath){ 
			var file,err = io.file(fpath,"rb") //注意 io.file 默认是文本方式读出的,b指定二进制模式 
			if( file ){  
				while( 
		    		var buf;
		    		buf,readSize = file.read(1024);
		    		buf
				) {
					client.writeBuffer(buf,readSize) ; 
				} 
				file.close(); 
				
				console.log("服务端发送文件完成"); 
			} 
		}
		
		client.close();
	}
)
 
console.log("服务端已关闭")
console.pause()
