给大家分享一个可以用来进行测试websocket的网页,个人觉得还是挺好用的.
WebSocket在线测试工具
还有一个小家伙ApiPost也可以进行使用websocket的测试。
在Spring Boot中使用WebSocket建立服务端,可以按照以下步骤进行:
org.springframework.boot
spring-boot-starter-websocket
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
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myHandler(), "/websocket/test/{sid}");
}
@Bean
public MyHandler myHandler() {
return new MyHandler();
}
}
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.TextWebSocketHandler;
public class MyHandler extends TextWebSocketHandler {
@Override
public void handleTextMessage(WebSocketSession session, TextMessage message) {
// 处理接收到的文本消息
System.out.println("Received message: " + message.getPayload());
}
@Override
public void onOpen(WebSocketSession session) {
// 连接建立成功调用的方法
System.out.println("New client connected: " + session.getPrincipal());
}
}
以上就是在Spring Boot中使用WebSocket建立服务端的步骤。注意,还需要根据实际情况进行进一步的配置和开发。
要使用Spring Boot建立一个客户端,可以按照以下步骤进行:
org.springframework.boot
spring-boot-starter-websocket
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.config.annotation.EnableWebSocketClient;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketClientConfigurer;
import org.springframework.web.socket.client.WebSocketClient;
import org.springframework.web.socket.client.standard.StandardWebSocketClient;
import org.springframework.web.socket.handler.TextWebSocketHandler;
@Configuration
@EnableWebSocketClient
public class WebSocketClientConfig implements WebSocketClientConfigurer {
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myHandler(), "/websocket/test/{sid}");
}
@Bean
public WebSocketClient myWebSocketClient() {
return new StandardWebSocketClient();
}
@Bean
public MyHandler myHandler() {
return new MyHandler();
}
}
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.TextWebSocketHandler;
public class MyHandler extends TextWebSocketHandler {
@Override
public void handleTextMessage(WebSocketSession session, TextMessage message) {
// 处理接收到的文本消息
System.out.println("Received message: " + message.getPayload());
}
}
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.messaging.simp.SimpMessageSendingOperations;
import org.springframework.social.connect.*;
import org.springframework.web.*;
import org.springframework.*;
import java.util.*;
@RestController("/")
@RequestMapping("/")
public class WebSocketController {
@Autowired
private SimpMessageSendingOperations operations;
@Autowired
private WebSocketConnectionEstablishedEvent event;
public void setEvent(WebSocketConnectionEstablishedEvent event) {
this.event = event;
}
@MessageMapping("/greet/{name}")
@SendTo("/topic/greet")
public String greet(@PathVariable String name) {
return "Hello, " + name + "!";
}
@RequestMapping(value = "/error", produces = MediaType.APPLICATION_JSON_VALUE)
public Map handleError(HttpServletRequest request) {
Map model = new HashMap<>();
model.put("timestamp", new Date());
model.put("status", HttpStatusInitializer.__getHttpStatus(request, NullPointerException));
model.put("error", "Internal Server Error");
model.put("exception", NullPointerException.__toString());
model.put("message", "Something bad happened, please try again!");
model.put("path", request.__toString());
return model;
}
@Autowired
private WebSocketClient myWebSocketClient;
@Autowired
private MyHandler myHandler;
@Autowired
private ConnectionRepository connectionRepository;
@Autowired
private AuthenticationRepository authenticationRepository;
public void sendMessageToUser(@PathVariable String name, @RequestParam String message) {
Iterable> connections = connectionRepository.findConnections(String FacebookMarker.ID);
for (Connection, ?> connection : connections) {
if (connection.getProvider().getId().equals(String FacebookMarker.ID) && connection.getDisplayName().equals(name)) {
connectionRepository.createSendToUserChannel(connection.getId()).send(MessageBuilder.withPayload(message).build());
break;
}
}
}
}
在上述代码中,我添加了一个sendMessageToUser
方法,它使用connectionRepository
查找与指定用户名匹配的连接,然后通过向该用户的个人通道发送消息来向该用户发送消息。请注意,这里假设您已经实现了与Facebook的连接,并且使用FacebookMarker
作为提供者的标识符。可以根据需要进行相应的调整。
要在Vue中订阅WebSocket连接并成为客户端,你可以按照以下步骤进行操作:
npm install webstomp-client
created()
钩子函数中创建连接。以下是一个示例代码片段:
在上述代码中,我们首先导入WebSocket库,并在created()
钩子函数中初始化WebSocket连接。你可以将wss://your-websocket-url
替换为实际的WebSocket服务器URL。然后,我们定义了连接的回调函数,包括onconnect
、onerror
、onclose
和onmessage
。这些回调函数将在相应的WebSocket事件发生时执行。 3. 处理WebSocket消息:当从WebSocket接收消息时,你可以在onmessage
回调函数中处理接收到的消息。你可以根据需要执行相应的操作,例如更新Vue组件的状态或触发其他行为。在上述示例代码中,我们只是简单地打印接收到的消息。 4. 发送WebSocket消息:要发送消息到WebSocket服务器,你可以使用WebSocket的send()
方法。在Vue组件中,你可以定义一个方法来发送消息,并在需要发送消息时调用该方法。以下是一个示例代码片段:
在上述代码中,我们添加了一个按钮,并在点击时调用sendMessage()
方法。该方法使用WebSocket的send()
方法发送消息到服务器。请注意,你需要将实际的消息内容替换为'Hello, WebSocket Server!'
。
