全局未在../node_modules/socket.io-parser/is-buffer.js中定义

问题描述

提前感谢帮助我。我正在尝试在我的一个角度组件中连接套接字，但是在浏览器的控制台中，它会抛出一个错误，说明没有在Object定义全局../ node_modules / socket.io-parser / is-buffer.js

thanks in advance for helping me out. I'm trying to connect socket in one of my angular components, but in the console of the browser it throws an error saying that global is not defined at Object ../node_modules/socket.io-parser/is-buffer.js

这是我的home.component.ts

This is my home.component.ts

import { Component, OnInit } from '@angular/core';
import * as $ from 'jquery';
import * as io from 'socket.io-client';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}


var socket = io();

如果我拿出socket.io-client和socket = io（）;网站很好但是当我把它包括在内时，就崩溃了。

If I take out the socket.io-client and socket = io(); the website is fine but when I include it, it crashes.

这是我的package.json文件

This is my package.json file

  "dependencies": {
    "@angular/animations": "^6.0.0",
    "@angular/common": "^6.0.0",
    "@angular/compiler": "^6.0.0",
    "@angular/core": "^6.0.0",
    "@angular/forms": "^6.0.0",
    "@angular/http": "^6.0.0",
    "@angular/platform-browser": "^6.0.0",
    "@angular/platform-browser-dynamic": "^6.0.0",
    "@angular/router": "^6.0.0",
    "@types/jquery": "^3.3.1",
    "@types/socket.io": "^1.4.33",
    "body-parser": "^1.18.3",
    "bootstrap": "^4.1.1",
    "core-js": "^2.5.4",
    "express": "^4.16.3",
    "jquery": "^3.3.1",
    "moment": "^2.22.1",
    "mongodb": "^3.1.0-beta4",
    "ng4-twitter-timeline": "^1.0.8",
    "popper.js": "^1.14.3",
    "rxjs": "^6.0.0",
    "socket.io": "^2.1.0",
    "socket.io-client": "^2.1.0",
    "zone.js": "^0.8.26"
  }

我首先尝试过只是'socket.io'哪个不起作用。然后我开始研究类似的问题。我一无所获。

I first tried with just 'socket.io' which didn't work. I then started researching for a similar problem. I found nothing.

我的最终目标是使用套接字从表单中获取数据并存储在数据库中。任何帮助将不胜感激。

My end goal is to use socket to take data from forms and store in a database. Any help would be much appreciated.

您必须使用：

UPDATE (POSSIBLE SOLUTION): 05/17/2018You have to use:

(window as any) = window 

$ b polyfill.ts中的
$ b

，这解决了我的问题。

in polyfill.ts, this resolved the problem for me.

更新（可能的解决方案＃2）：05/29 / 2018

(window as any).global = window

推荐答案

(window as any).global = window

正如评论中已提到的，在 polyfills.ts file。

As already mentioned in comment, add the above code in the polyfills.ts file.
