我无法创建要部署在 Azure 上的 Node.JS Web 应用

过去一周，我一直在尝试让 Azure 使用 Node.JS 部署一个可访问的网站。让我重新回顾一下我所做的步骤。

1) 我转到 Visual Studio，然后选择基本 Azure Node.js Express 4 应用程序。

2）我得到一个基本项目，我运行该项目并在浏览器上打开本地主机以确认我可以查看提供的基本页面。

3)我将所有代码提交到Azure Git存储库。

4）我在 Azure 上创建了一个管道，通过使用我的 Azure git repo 上的代码，允许它自动创建自己的 yaml 文件，如下所示：

# Node.js Express Web App to Linux on Azure
# Build a Node.js Express app and deploy it to Azure as a Linux web app.
# Add steps that analyze code, save build artifacts, deploy, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/javascript

trigger:
- master

variables:

  # Azure Resource Manager connection created during pipeline creation
  azureSubscription: '<Censored>'

  # Web app name
  webAppName: 'TheEclipsedLock-Basic-Portfolio-Website-012345'

  # Environment name
  environmentName: 'TheEclipsedLock-Basic-Portfolio-Website-012345'

  # Agent VM image name
  vmImageName: 'ubuntu-latest'

stages:
- stage: Build
  displayName: Build stage
  jobs:  
  - job: Build
    displayName: Build
    pool:
      vmImage: $(vmImageName)

    steps:
    - task: NodeTool@0
      inputs:
        versionSpec: '10.x'
      displayName: 'Install Node.js'

    - script: |
        npm install
        npm run build --if-present
        npm run test --if-present
      displayName: 'npm install, build and test'

    - task: ArchiveFiles@2
      displayName: 'Archive files'
      inputs:
        rootFolderOrFile: '$(System.DefaultWorkingDirectory)'
        includeRootFolder: false
        archiveType: zip
        archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
        replaceExistingArchive: true

    - upload: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
      artifact: drop

- stage: Deploy
  displayName: Deploy stage
  dependsOn: Build
  condition: succeeded()
  jobs:
  - deployment: Deploy
    displayName: Deploy
    environment: $(environmentName)
    pool: 
      vmImage: $(vmImageName)
    strategy:
      runOnce:
        deploy:
          steps:            
          - task: AzureWebApp@1
            displayName: 'Azure Web App Deploy: TheEclipsedLock-Basic-Portfolio-Website-012345'
            inputs:
              azureSubscription: $(azureSubscription)
              appType: webAppLinux
              appName: $(webAppName)
              runtimeStack: 'NODE|10.10'
              package: $(Pipeline.Workspace)/drop/$(Build.BuildId).zip
              startUpCommand: 'npm run start'

好的，我要做的就是等待管道完成，对吧？很简单，对吧？

然后我得到这个：

##[section]Finishing: npm install, build and test

过去几天我一直在谷歌上搜索，我看到的各种答案都包括删除 package.json 文件以仅使用 npm init 命令，但是如果我使用 npm init，Azure 的终端就会永远卡住，因为它需要输出，而由于 Azure 的性质，我无法简单地通过它的窗口将我自己的输出提供给它。

在我开发了一个小型基本网站的单独项目中，我创建了以下 yaml 文件：

# Node.js
# Build a general Node.js project with npm.
# Add steps that analyze code, save build artifacts, deploy, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/javascript

trigger:

- feature/*

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: NodeTool@0
  inputs:
    versionSpec: '10.x'
  displayName: 'Install Node.js'

- script: |
    cd AzureWebsite
    npm install
    npm install express
    npm install chai
    npm install mocha
    npm install request
    npm install supertest
    npm install mocha-junit-reporter --save-dev
    npm publish
    cd test
    cd root
    npm install -g mocha
    mocha -R spec server_test.js

- task: ArchiveFiles@2
  displayName: 'Compressing to zip...'
  inputs:
    rootFolderOrFile: '$(System.DefaultWorkingDirectory)'
    includeRootFolder: false
#    archiveType: 'zip'
#    archiveFile: 'web.zip'
#    replaceExistingArchive: true 

- script: |
    ls


- task: CopyFiles@2
  displayName: 'Copying Files...'
  inputs:
    SourceFolder: '$(Build.SourcesDirectory)'
    Contents: |
        **/*
        package.json
    TargetFolder: '$(build.artifactstagingdirectory)'

- task: PublishBuildArtifacts@1
  displayName: 'Publishing Artifacts...'

中间脚本的目的是对某些网页是否可访问进行单元测试。ArchiveFiles@2 有助于部署，因为发布管道抱怨它没有任何 zip 文件可供使用，所以我只使用工作目录的 zip。我希望它进入应该发布的工件暂存目录。

然后我将压缩的工件文件插入发布管道……你看，它完成了！现在我可以坐下来观看我的网站了——

说实话，我对此束手无策。我不知道我能做什么，而且我几乎找不到谷歌上的资源，因为它们都暗示我没有使用 Azure。我知道一些同行正在做和我一样的事情，我听从了他们的建议并观看了他们自己的教程，但没有人能解决我遇到的问题。我祈祷有人能帮我指明正确的方向，因为我不知道该怎么做。

在提出任何评论之前：是的，我是 Node.JS 的新手，我只想部署一些东西，这样我才能知道它能正常工作。老实说，我正盲目地寻找一个可以在线工作的配置，即使通过本地主机也可以正常工作。不，我不能切换到 Node.JS 以外的其他东西，因为我在过去几天里已经投入了大量时间来尝试部署一些最基本的功能。

感谢您抽出时间来阅读。
