ios - 无法在服务器(SpringBoot)和 iOS 之间建立 WebSocket 连接

Question

我正在尝试在 iOS 和服务器 (SpringBoot) 之间建立 WebSocket 连接。从服务器端，我们正在使用这样的 WebSocket 连接。

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker(URLMapping.WS_SEND);
        config.setApplicationDestinationPrefixes(URLMapping.WS_PREFIX);
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/api/v1/transactionSocket").setAllowedOrigins("*").withSockJS();
    }
}

在IOS中，我用过StompClient用于建立 WebSocket 连接的库。

func makeConnection() {
    let client = StompClient(url: URL(string: "/api/v1/transactionSocket")!)
    client.delegate = self
    client.connect() 
}

func disconnectConnection() {
    client.disconnect()
    print("Disconnecting :\(client)")
}

func stompClientDidConnected(_ client: StompClient) {
    print("Stomp got connected: \(client) .... \(client.isConnected)")
    // client.subscribe("API")
}

func stompClient(_ client: StompClient, didErrorOccurred error: NSError) {
    print("Stomp Error occures \(client)   errror: \(error)")
}

func stompClient(_ client: StompClient, didReceivedData data: Data, fromDestination destination: String) {
    print("Cliemt: \(client)  Data: \(data) destination: \(destination)")
}

在运行时，既没有建立连接，也没有调用“stompClientDidConnected”委托(delegate)方法。

我没怎么用过WebSocket。所以无法理解原因是什么。任何帮助将不胜感激。

谢谢

你可以使用StopmClientLib来建立socket连接，它也有subscribe方法。
