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.
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:
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-websocket</artifactId>
- </dependency>
- 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:
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-websocket</artifactId>
- </dependency>
- 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:- <template>
- <div>
-
- div>
- template>
-
- <script>
- import WebSocket from 'webstomp-client';
-
- export default {
- name: 'WebSocketClient',
- data() {
- return {
- socket: null,
- };
- },
- created() {
- this.initializeWebSocket();
- },
- methods: {
- initializeWebSocket() {
- this.socket = new WebSocket('wss://your-websocket-url'); // 使用你的WebSocket URL
- this.socket.onconnect = () => {
- console.log('WebSocket connected');
- };
- this.socket.onerror = (error) => {
- console.error('WebSocket error:', error);
- };
- this.socket.onclose = () => {
- console.log('WebSocket disconnected');
- };
- this.socket.onmessage = (message) => {
- console.log('Received message:', message);
- };
- },
- },
- };
- script>
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:
- <template>
- <div>
-
- <button @click="sendMessage">Send Messagebutton>
- div>
- template>
-
- <script>
- import WebSocket from 'webstomp-client';
-
- export default {
- name: 'WebSocketClient',
- data() {
- return {
- socket: null,
- };
- },
- created() {
- this.initializeWebSocket();
- },
- methods: {
- initializeWebSocket() { /* ... */ }, // WebSocket连接初始化代码省略
- sendMessage() {
- const message = 'Hello, WebSocket Server!'; // 待发送的消息内容
- this.socket.send(message); // 发送消息到WebSocket服务器
- },
- },
- };
- script>
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!'
。
