Question

我正在尝试将一些事件从节点客户端发送到Laravel回显服务器。

互联网上没有太多的文档。我尝试使用socket.emit()来做到这一点，但是没有事件到达echo服务器。

这是我的app.ts代码

import express = require('express');
import Echo from "laravel-echo";
import SocketIoClient from "laravel-echo";


// Create a new express application instance
const app: express.Application = express();
let io = require('socket.io-client');

let echo = new Echo({
  broadcaster: 'socket.io',
  host: 'http://3.16.169.253:6001',
  client: io
});


echo.channel('public').listen('drumdata', (e:any) => {
  console.log("DATA RECEIVED");
  console.log(e);
})

sendData();

async function sendData(){
for(let i=0;i<10;i++){
  await sleep(2000) 
  echo.connector.options.auth.headers['X-Socket-ID'] = echo.connector.socket.id
  echo.connector.socket.emit('drumdata', "public",{"eventData":"myData"}) ;

 }
}




function sleep(ms:number) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

Echo-Server日志显示应用程序已加入频道，但未触发任何事件。

[3:25:25 PM] - S6s3SKH1L61C9U6NAAAr joined channel: public
[3:25:59 PM] - S6s3SKH1L61C9U6NAAAr left channel: public (transport close)
[3:26:08 PM] - qZljcx9BzDZOU-s8AAAs joined channel: public
[3:26:14 PM] - qZljcx9BzDZOU-s8AAAs left channel: public (transport close)
[3:27:02 PM] - 9--wTFOpWlZVIfw4AAAt joined channel: public

有人对此有建议吗？

编辑：

在DEBUG模式下运行laravel-echo-server显示消息已接收，但没有事件触发该通道。我什至还添加了“ X-Socket-ID”身份验证标头。

好的，所以我开始看这一切如何工作，该文档并没有多大帮助，但是看起来echo服务器使用http api来发布消息。在这种情况下，他们似乎推荐axios。该解决方案应该可以工作，但是我无法弄清楚通道的路径应该是什么。一旦怀疑了这一点，就应该看到事件是从节点服务器传播的。目前只有404个。

const express = require('express');
const Echo = require('laravel-echo');
const io = require('socket.io-client');
const axios = require('axios');

// Create a new express application instance
const app = express();

const echo = new Echo({
  broadcaster: 'socket.io',
  host: 'http://127.0.0.1:6001',
  client: io
});


echo.channel('public').listen('drumdata', (e) => {
  console.log("DATA RECEIVED");
  console.log(e);
})


async function sendData(){
for(let i=0;i<10;i++){
  await sleep(2000);
  console.log('echoing'); // echo.socketId() is already set on X-Socket-Id thanks to Axios
  axios.post('http://127.0.0.1:6001/public/drumdata', {"eventData":"myData"})
    .then((response) => {
        console.log(response);
    });

 }
}

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

sendData();

将事件从Node Client发送到Laravel Echo服务器
