我正在嘗試將我的react.jsocks客戶端連接到我的spring boot後端Web套接字，但我無法連接它們，它在chrome控制台上給了我一些錯誤，如下所示：
chrome 控制台錯誤
我的 Spring Boot 部分沒有任何錯誤，但有一些類似的警告：
彈簧啟動控制台
為什麼我無法連接它們我的react.js部分是這樣的：

和我的 Spring Boot 設定類別：
package com.project.blog.websocket;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfiguration implements WebSocketMessageBrokerConfigurer {
@Value("${blog.app.front}")
private String url;
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/wss").setAllowedOrigins(url).setAllowedOriginPatterns("*").withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.setApplicationDestinationPrefixes("/app");
registry.enableSimpleBroker("/user-connect");
registry.setUserDestinationPrefix("/user");
}
}
同樣對於網路套接字控制器我寫了這部分：
package com.project.blog.websocket;
import com.project.blog.entities.User;
import com.project.blog.repositories.UserRepository;
import com.project.blog.responses.ErrorSuccessResponse;
import lombok.RequiredArgsConstructor;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Controller;
import java.time.LocalDateTime;
import java.util.LinkedList;
import java.util.List;
@Controller
@RequiredArgsConstructor
public class WebSocketController {
private final SimpMessagingTemplate simpMessagingTemplate;
private final UserRepository userRepository;
@MessageMapping("/message")
private ErrorSuccessResponse receiveMessage(String user){
ErrorSuccessResponse errorSuccessResponse = new ErrorSuccessResponse();
errorSuccessResponse.setError("block oldu");
simpMessagingTemplate.convertAndSendToUser(user,"/private",errorSuccessResponse);
return errorSuccessResponse;
}
@Scheduled(fixedDelay = 1000)
private void checkBlocks(){
LocalDateTime now = LocalDateTime.now();
List<User> users = userRepository.findBlockedUsers(now);
users.stream().forEach(user->{
receiveMessage(user.getUsername());
});
}
}
我嘗試使用襪子連接我的react.js前端和spring boot後端，但我做不到
我的 process.env.REACT_APP_ROOT_URL 是：http://localhost:1998 和@Value(“${blog.app.front}”) 私有字串 url；這部分值是：http://localhost:3000
問題可能出在客戶端或伺服器端。第一步是能夠使用測試工具單獨測試伺服器。這並不容易，因為程式碼在 SockJS 上使用 STOMP 協定。
您可能不需要使用 SockJS。請參閱將 STOMP 與 SockJS 結合使用。所以第一步是刪除 SockJS 的使用，看看它是否有效。
下一步是取消 STOMP 的使用。一種更簡單的方法是僅使用純文字訊息。如果您這樣做，則可以使用命令列工具，例如 wscat 或 Chrome 瀏覽器外掛程式例如 WebSocketKing 來自行測試伺服器。一旦伺服器與測試工具一起工作，您就可以使用客戶端程式碼進行測試。
我遇到了類似的問題，最終使用 JSON 訊息開發了自己的協議，以 WebSocket 文字訊息的形式發送。我可以使用 WebSocket King 單獨測試伺服器。捲動到 Brill Middleware 的末尾查看使用 WebSocket King 的範例。
