【问题描述】：

我参考了这个spring boot doc 在 Spring Boot 中创建 Web 套接字。

我用过stompjs 和sockjs-client

var socket = new SockJS('/gs-guide-websocket');
//gives an error in below line
stompClient = Stomp.over(socket);
stompClient.connect({}, function (frame) {
    setConnected(true);
    console.log('Connected: ' + frame);
    stompClient.subscribe('/topic/greetings', function (greeting) {
        showGreeting(JSON.parse(greeting.body).content);
    });
});

标签： spring-boot react-native websocket

【解决方案1】：

使用这个stompjs 和socket-client

然后导入它们

import SockJS from 'sockjs-client';
import Stomp from 'stompjs';

连接websocket

//use your link here
var sock = new SockJS('http://localhost:8102/api/ws');
let stompClient = Stomp.over(sock);
sock.onopen = function() {
  console.log('open');
}
stompClient.connect({}, function (frame) {
   console.log('Connected: ' + frame);
   stompClient.subscribe('/topic/public', function (greeting) {
     console.log(greeting);
     //you can execute any function here
   });
});
