websocket带参数连接

WebSocket可以通过在连接URL中添加参数来进行带参数连接。在Spring Boot项目中,可以通过WebSocketConfig配置类来实现带参数连接。在该配置类中,可以使用`@PathVariable`注解来获取连接URL中的参数,并将其传递给WebSocket处理程序。例如,可以在`registerWebSocketHandlers`方法中使用`{account}`作为路径变量,并将其传递给WebSocket处理程序。以下是一个示例配置类的代码:
```java
@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
@Autowired
private MyWsHandler myWsHandler;
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myWsHandler, "myWs/{account}")
.setAllowedOrigins("*");
}
}
```
在上述示例中,`{account}`是一个路径变量,可以在连接URL中进行替换。例如,如果要连接到`myWs`路径并传递`account`参数为`12345`,可以使用以下URL进行连接:`ws://localhost:8080/myWs/12345`。这样,WebSocket处理程序就可以获取到`account`参数并进行相应的处理。
