[22/02/19]チャット機能を実施する(1)
51515 ワード
注意:https://dev-gorany.tistory.com/212?category=901854
本当によく整理されていて、簡単に体現できました.
ノードとしてのチャット機能ではエラーを見つけることができず,次回再試行し,Webソケットで実現することにした.
チャット>ChatHandler/WebSocketConfigの作成
ChatHandler
package com.phl.cocolo.chatting;
import lombok.extern.log4j.Log4j2;
import org.springframework.stereotype.Component;
import org.springframework.web.socket.CloseStatus;
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.TextWebSocketHandler;
import java.util.ArrayList;
import java.util.List;
@Component
@Log4j2
public class ChatHandler extends TextWebSocketHandler {
private static List<WebSocketSession> list = new ArrayList<>();
@Override
protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
String payload = message.getPayload();
log.info("payload : " + payload);
for(WebSocketSession sess: list) {
sess.sendMessage(message);
}
}
/* Client가 접속 시 호출되는 메서드 */
@Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
list.add(session);
log.info(session + " 클라이언트 접속");
}
/* Client가 접속 해제 시 호출되는 메서드드 */
@Override
public void afterConnectionClosed(WebSocketSession session, CloseStatus status) throws Exception {
log.info(session + " 클라이언트 접속 해제");
list.remove(session);
}
}なぜWebソケットを使用するときにcorsエラーをキャプチャしやすいのですか?今度ノードをもう一度試してみると、わかります.
package com.phl.cocolo.chatting;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;
@Configuration
@RequiredArgsConstructor
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
private final ChatHandler chatHandler;
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(chatHandler, "ws/chat").setAllowedOrigins("*");
}
}モードを使ってチャットウィンドウを開くことにしました.

</html>勉強したらグループチャットをしたり、通話料を払ったりします.
