如何从 PHP 控制器发出 socket.io 事件?
我正在使用 Yii2 框架开发一个 PHP 网站,并尝试实现一个 socket.io 服务。
要执行 socket.io,我使用 PM2,我的文件如下所示:
const { fstat } = require('fs');
var socket = require('socket.io'),
express = require('express'),
https = require('https');
fs = require('fs');
const credentials = {
key: fs.readFileSync('../../../ssl/keys/<path_to_cert_key.key>').toString(),
cert: fs.readFileSync('../../../ssl/certs/<path_to_cert.crt>').toString(),
}
var app = express();
var server = https.createServer(credentials, app);
var io = socket(server, {
cors: {
origin: '<origin_url>',
methods: ['POST', 'GET'],
credentials: true
},
allowEIO3: true,
secure: true
});
io.sockets.on('connection', function(client){
console.log('ok');
client.on('test', function(data){
console.log('test');
console.log(data);
io.sockets.emit('test_r', {message: 'ok'});
});
});
server.listen(30064);
它运行时没有任何错误:
pm2 start _socket.js
我可以通过注册 javascript 轻松地从视图访问此套接字:
var socket = io.connect('<socket_url:port>', {
withCredentials: false,
});
socket.on('test_r', function( data ) {
console.log('it works');
});
如果我连接到套接字并从视图发出,它会很好地工作。 但问题是我想从 PHP 控制器或 PHP 函数中的 CoreBootstrap 对象发出一个事件,如下所示:
$emitter = new \SocketIO\Emitter( array( 'port' => '30064', 'host' => '127.0.0.1') );
$emitter->broadcast->emit( 'test', ['message' => 'test_message'] );
我使用的模块是 ashiina/socket.io-emitter (我也尝试了很多其他方法,但是他们也没有工作)。 当我这样做时什么也没有发生。当我查看 PM2 日志时,什么也没有发生。
有人知道为什么没有发出事件或者是否有其他方法可以做到这一点?
预先感谢您的回答。
I'm developping a PHP website using the Yii2 Framework and I'm trying to implement a socket.io service.
To execute socket.io I use PM2 and my file looks like this :
const { fstat } = require('fs');
var socket = require('socket.io'),
express = require('express'),
https = require('https');
fs = require('fs');
const credentials = {
key: fs.readFileSync('../../../ssl/keys/<path_to_cert_key.key>').toString(),
cert: fs.readFileSync('../../../ssl/certs/<path_to_cert.crt>').toString(),
}
var app = express();
var server = https.createServer(credentials, app);
var io = socket(server, {
cors: {
origin: '<origin_url>',
methods: ['POST', 'GET'],
credentials: true
},
allowEIO3: true,
secure: true
});
io.sockets.on('connection', function(client){
console.log('ok');
client.on('test', function(data){
console.log('test');
console.log(data);
io.sockets.emit('test_r', {message: 'ok'});
});
});
server.listen(30064);
It runs without any error:
pm2 start _socket.js
I can easily access this socket from a view by registering javascript :
var socket = io.connect('<socket_url:port>', {
withCredentials: false,
});
socket.on('test_r', function( data ) {
console.log('it works');
});
It works well if I connect to the socket and emit from a view.
But the thing is that I want to emit an event from a PHP Controller or from a CoreBootstrap Object in a php function like this :
$emitter = new \SocketIO\Emitter( array( 'port' => '30064', 'host' => '127.0.0.1') );
$emitter->broadcast->emit( 'test', ['message' => 'test_message'] );
The module I'm using is ashiina/socket.io-emitter (I also tried a bunch of ohters but they did not work as well).
Nothing happens when I do this. Nothing even happens when I look at the PM2 logs.
Would someone know why the event is not emitted or if there is another way to do it ?
Thanks in advance for your answers.
