Question

我正在尝试将我的NEXTJS应用程序部署到天蓝色。我创建了一个Web应用程序，并安装了包含Node的Linux OS。我的package.json看起来像这样。

{
  "name": "frontend",
  "version": "1.0.0",
  "description": "This package contains all necessary depenencies for frontned",
  "main": "index.js",
  "scripts": {
    "dev": "next",
    "build": "next build",
    "start": "next start -p $PORT",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "masnad",
  "license": "ISC",
  "dependencies": {
    "@zeit/next-css": "^1.0.1",
    "next": "^8.0.3",
    "react": "^16.8.3",
    "react-dom": "^16.8.3"
  }
}

我首先创建了一个空的Web应用程序，然后使用了部署服务kudu，在那里我将代码从本地推送到了Azure。

推送到天蓝色时的git日志如下

To https://node-ax-dev.scm.azurewebsites.net:443/node-ax-dev.git
   ec4d5ad..dcadc02  development -> master

所以我猜它部署得很好。我去了https://node-ax-dev-1212.azurewebsites.net，但是什么也没发生。

因此，我在实例内进行SSH加密，然后运行npm run dev，它立即向我显示了该项目在localhost：3000上运行。

所以我写了https://node-ax-dev-1212.azurewebsites.net:3000，但是它没有作用，因为它在终端中告诉端口该端口已被使用并关闭。

我不确定出什么问题，但是感觉我正确地执行了大多数步骤。

我没有添加任何特定的env变量，因此所有内容都是全新的。我的目录如下所示。

P.S我还尝试在应用程序设置runtime中添加启动文件命令npm run dev，但我认为它不起作用。

Answer 1

Azure需要一个web.config文件以及一个server.js / index.js作为起点，否则它将无法启动。

我建议更改您的文件夹结构。参见下面的例子 https://github.com/zeit/next.js/tree/master/examples/custom-server

创建server.js文件，并从上述github存储库中复制信息。在package.json文件中，将dev build and start替换为

"dev": "node server.js",
"build": "next build",
"start": "node server.js"

现在，您可以仅使用node server.js来运行代码。

将其上传到azure时，在您的根目录中创建一个文件调用web.config，并在下面添加代码。

<?xml version="1.0" encoding="utf-8"?>
<!--
     This configuration file is required if iisnode is used to run node processes behind
     IIS or IIS Express.  For more information, visit:
     https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config
-->

<configuration>
  <system.webServer>
    <!-- Visit http://blogs.msdn.com/b/windowsazure/archive/2013/11/14/introduction-to-websockets-on-windows-azure-web-sites.aspx for more information on WebSocket support -->
    <webSocket enabled="false" />
    <handlers>
      <!-- Indicates that the server.js file is a node.js site to be handled by the iisnode module -->
      <add name="iisnode" path="server.js" verb="*" modules="iisnode"/>
    </handlers>
    <rewrite>
      <rules>
        <!-- Do not interfere with requests for node-inspector debugging -->
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
          <match url="^server.js\/debug[\/]?" />
        </rule>

        <!-- First we consider whether the incoming URL matches a physical file in the /public folder -->
        <rule name="StaticContent">
          <action type="Rewrite" url="public{REQUEST_URI}"/>
        </rule>

        <!-- All other URLs are mapped to the node.js site entry point -->
        <rule name="DynamicContent">
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
          </conditions>
          <action type="Rewrite" url="server.js"/>
        </rule>
      </rules>
    </rewrite>

    <!-- 'bin' directory has no special meaning in node.js and apps can be placed in it -->
    <security>
      <requestFiltering>
        <hiddenSegments>
          <remove segment="bin"/>
        </hiddenSegments>
      </requestFiltering>
    </security>

    <!-- Make sure error responses are left untouched -->
    <httpErrors existingResponse="PassThrough" />

    <!--
      You can control how Node is hosted within IIS using the following options:
        * watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
        * node_env: will be propagated to node as NODE_ENV environment variable
        * debuggingEnabled - controls whether the built-in debugger is enabled
      See https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config for a full list of options
    -->
    <!--<iisnode watchedFiles="web.config;*.js"/>-->
  </system.webServer>
</configuration>

根据需要通过调整server.js文件对路由进行添加和更改后。

将其推送到azure，您的应用程序将开始运行，因为azure现在将运行node server.js并知道在哪里可以找到它。并且web.config文件还将重写URL，因此您不必添加yoururl.azure.net:3000，只需简单地键入URL即可。

通过对我的应用程序进行以下更改，我能够使Next.js在Azure Appservices上运行。对Express应用程序和package.json文件进行以下更改。

// server.js

const express = require('express')
const next = require('next')

const dev = process.env.NODE_ENV !== 'production'
const app = next({ dev })
const handle = app.getRequestHandler()

// Your app will get the Azure port from the process.enc.PORT
const port = process.env.PORT || 3000;

app
  .prepare()
  .then(() => {
     const server = express()

     server.get('*', (req, res) => {
         return handle(req, res)
     })

     server.listen(port, err => {
        if (err) throw err
            console.log('> Ready on http://localhost:3000')
        })
     })
     .catch(ex => {
         console.error(ex.stack)
         process.exit(1)
     })

在package.json文件中，需要确保您具有postinstall和start的脚本。首先，您可以添加以下端口变量。

"scripts": {
  "dev": "next",
  "build": "next build",
  "start": "next start -p $PORT",
  "postinstall": "next build"
}

我有一篇博客文章，介绍如何解决http://localhost:8000/blog/running-next-js-on-azure-app-services

无法将下一个js部署到Azure
