我正在按照此链接创建一个协作绘图应用程序。我能够运行应用程序，但没有发生协作绘图。我已成功创建PUSHER_APP_ID, PUSHER_KEY, PUSHER_SECRET& 放置在.env.
协同绘图代码 -
ngAfterViewInit() {
const channel = this.pusher.init();
console.log("ngAfterViewInit called :: line 142 : ", this.userId);
channel.bind('draw', (data) => {
console.log("line 144");
if (data.userId !== this.userId) {
console.log("line 146");
data.line.forEach((position) => {
console.log("line 148");
this.draw(position.start, position.stop, this.guestStrokeStyle);
});
}
});
}
如果我在不同的浏览器中点击它，我可以看到不同的用户 ID。但它不会进入下面的循环。
channel.bind('draw', (data) => {
...
}
server.js我可以从代码中看到日志-
app.post('/draw', (req, res) => {
console.log("draw :: in server :: ", req.body);
pusher.trigger('painting', 'draw', req.body);
res.json(req.body);
});
日志 -

如果我在任何地方做错或遗漏任何东西，任何人都可以帮助/指导。
