部署 + 使用 CLI 客户端时 Heroku 应用程序错误

程序问答   发布时间：2022-06-01  发布网站：大佬教程  code.js-code.com
大佬教程收集整理的这篇文章主要介绍了部署 + 使用 CLI 客户端时 Heroku 应用程序错误，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决部署 + 使用 CLI 客户端时 Heroku 应用程序错误？

开发过程中遇到部署 + 使用 CLI 客户端时 Heroku 应用程序错误的问题如何解决？下面主要结合日常开发的经验，给出你关于部署 + 使用 CLI 客户端时 Heroku 应用程序错误的解决方法建议，希望对你解决部署 + 使用 CLI 客户端时 Heroku 应用程序错误有所启发或帮助；

我正在处理一个项目，其中我必须让 Node.Js Cli 客户端与 Heroku 服务器通信。

我尝试部署一个简单的聊天应用程序示例以确保一切正常，但遇到了 Heroku 错误，提示“应用程序发生错误，无法提供您的页面。如果您是应用程序所有者，请检查您的日志以获取详细信息。您可以从 Heroku Cli 使用命令 heroku logs --tail"

这是我运行上述命令时的 Heroku 日志，我很确定该错误与服务器在部署时无法加载 socket-io 模块有关：

此外，我的 procfile 中有 web: node index.Js。

我不太确定为什么会发生这种情况，因为我在本地安装了 socket-io，并且在本地测试时服务器和客户端工作正常。

我的第二个问题是关于客户端和服务器代码。由于我可以在本地测试时对端口值进行硬编码，因此客户端和服务器进行通信。但是，我如何让客户端与 Heroku 中运行的 index.Js 代码对话（假设我解决了第一个问题）？

我的客户端 (clIEnt.Js) 和服务器 (index.Js) 代码如下：

//server code

const http = require('http').createServer()
const io = require('socket.io')(http)
const port = process.env.PORT || 3000

http.Listen(port,() => console.log('server Listening on port: ' + port))

io.on('connection',(socket) => {
    console.log('connected')
    socket.on('message',(evt) => {
        console.log(evt)
        socket.broadcast.emit('message',evt)
    })
})

//clIEnt code

//ObvIoUsly,this localhost value will not work,but what should I change it to instead?
var socket = require('socket.io-clIEnt')('http://localhost:3000')
const repl = require('repl')
const chalk = require('chalk')
var username = null

socket.on('disconnect',function() {
    socket.emit('disconnect')
})

socket.on('connect',() => {
    console.log(chalk.red('== start chatTing =='))
    username = process.argv[2]
})

socket.on('message',(data) => {
    const { cmd,username } = data
    console.log(chalk.green(username + ': ' + cmd.split("\n")[0]))
})

repl.start({
    prompt: '',eval: (cmd) => {
        socket.send({CR_493_11845@d,usernamE})
    }
})
