Custom WebSocket
下面是一个完整的使用WebSockets底层引擎包的实例。
Client
import WebSockets
try WebSocket.connect(to: url) { ws in
print("Connected to \(url)")
ws.onText = { ws, text in
print("[event] - \(text)")
}
ws.onClose = { ws, _, _, _ in
print("\n[CLOSED]\n")
}
}
Server
import HTTP
import WebSockets
import Transport
final class MyResponder: Responder {
func respond(to request: Request) throws -> Response {
return try request.upgradeToWebSocket { ws in
print("[ws connected]")
ws.onText = { ws, text in
print("[ws text] \(text)")
try ws.send("🎙 \(text)")
}
ws.onClose = { _, code, reason, clean in
print("[ws close] \(clean ? "clean" : "dirty") \(code?.description ?? "") \(reason ?? "")")
}
}
}
}
let port = 8080
let server = try Server<TCPServerStream, Parser<Request>, Serializer<Response>>(port: port)
print("Connect websocket to http://localhost:\(port)/")
try server.start(responder: MyResponder()) { error in
print("Got server error: \(error)")
}
