将 Django 应用程序部署到 Azure VS2017 - 自定义 python

Question

我在 Visual Studio 2017 中使用 Django 制作了一个简单的应用程序，利用 Visual Studio 中的默认模板（文件 - 新建 - 项目 - python - django Web 应用程序）。我已经通过 azure 门户安装了 django PTVS，并添加了一个自定义 python 扩展。该应用程序在本地正常运行，但在我通过 Visual Studio 将其部署到 Azure 后，我只能访问显示的页面：

'Your App Service app has been created.'

我已经阅读了几篇文章 (Deploy a simple VS2017 Django app to Azure - server error) 并遵循了以下教程：https://docs.microsoft.com/en-us/visualstudio/python/managing-python-on-azure-app-service

我的 web.config 如下所示：

<?xml version="1.0"?>
<configuration>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
    <handlers>
      <remove name="Python27_via_FastCGI" />
      <remove name="Python34_via_FastCGI" />
      <add name="PythonHandler" path="handler.fcgi" verb="*" modules="FastCgiModule" scriptProcessor="D:\home\python361x64\python.exe|D:\home\python361x64\wfastcgi.py" resourceType="Unspecified" requireAccess="Script"/>
    </handlers>
  </system.webServer>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <appSettings>
    <add key="PYTHONPATH" value="%SystemDrive%\home\site\wwwroot" />
    <add key="WSGI_HANDLER" value="DjangoWebProject2.wsgi.application()"/>
    <add key="DJANGO_SETTINGS_MODULE" value="app.settings" />
  </appSettings>
</configuration>

更新：

我设法让它工作，问题是它仍然继续使用带有 python 3.4 的环境，并且似乎存在需要更新版本的 python 的包依赖项，因此我更改了应用程序设置如下。

<configuration>
  <appSettings>
    <add key="WSGI_HANDLER" value="myApp.wsgi.application"/>
    <add key="PYTHONPATH" value="D:\home\site\wwwroot"/>
    <add key="WSGI_LOG" value="D:\home\LogFiles\wfastcgi.log"/>
    <add key="PYTHONPATH" value="D:\home\site\wwwroot" />
    <add key="DJANGO_SETTINGS_MODULE" value="myApp.settings" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
    <handlers>
      <add name="PythonHandler" path="handler.fcgi" verb="*" modules="FastCgiModule" scriptProcessor="D:\home\python362x86\python.exe|D:\home\python362x86\wfastcgi.py" resourceType="Unspecified" requireAccess="Script"/>
    </handlers>
    <rewrite>
      <rules>
        <rule name="Static Files" stopProcessing="true">
          <conditions>
            <add input="true" pattern="false" />
          </conditions>
        </rule>
        <rule name="Configure Python" stopProcessing="true">
          <match url="(.*)" ignoreCase="false" />
          <conditions>
            <add input="{REQUEST_URI}" pattern="^/static/.*" ignoreCase="true" negate="true" />
          </conditions>
          <action type="Rewrite" url="handler.fcgi/{R:1}" appendQueryString="true" />
        </rule>
      </rules>
    </rewrite>
  </system.webServer>
</configuration>

我试图重现您的问题，但失败了。我的 Django 应用程序由 VS2017 创建并部署到 Azure WebApps，它可以工作。有一些类似的 SO 线程与您的问题相同。

1. Only getting Your App Service app has been created - after deploying to azure
2. Django web app deploy in Azure via Visual Studio 2017

您可以按照上述主题再试一次。您也可以参考the official tutorial for Django 创建您的 django 应用程序并将其部署到 Azure，然后更改您的 web.config 以使用 Python 3.6.1 扩展。

这是我的web.config 文件的内容如下。

<?xml version="1.0"?>
<!-- Generated web.config for Microsoft Azure. Remove this comment to prevent
     modifications being overwritten when publishing the project.
-->
<configuration>
  <system.diagnostics>
    <trace>
      <listeners>

          <filter type="" />
        </add>
      </listeners>
    </trace>
  </system.diagnostics>
  <appSettings>
    <add key="WSGI_ALT_VIRTUALENV_HANDLER" value="django.core.wsgi.get_wsgi_application()" />
    <add key="WSGI_ALT_VIRTUALENV_ACTIVATE_THIS" value="D:\home\site\wwwroot\env\Scripts\activate_this.py" />
    <add key="WSGI_HANDLER" value="ptvs_virtualenv_proxy.get_virtualenv_handler()" />
    <add key="PYTHONPATH" value="D:\home\site\wwwroot" />
    <add key="DJANGO_SETTINGS_MODULE" value="JayGongDjango.settings" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
    <handlers>
      <add name="PythonHandler" path="handler.fcgi" verb="*" modules="FastCgiModule" scriptProcessor="D:\home\python361x64\python.exe|D:\home\python361x64\wfastcgi.py" resourceType="Unspecified" requireAccess="Script"/>
    </handlers>
    <rewrite>
      <rules>
        <rule name="Static Files" stopProcessing="true">
          <conditions>
            <add input="true" pattern="false" />
          </conditions>
        </rule>
        <rule name="Configure Python" stopProcessing="true">
          <match url="(.*)" ignoreCase="false" />
          <conditions>
            <add input="{REQUEST_URI}" pattern="^/static/.*" ignoreCase="true" negate="true" />
          </conditions>
          <action type="Rewrite" url="handler.fcgi/{R:1}" appendQueryString="true" />
        </rule>
      </rules>
    </rewrite>
  </system.webServer>
</configuration>

---

总结一下，问题是项目一直在使用带有python 3.4的环境。只需将其更改为新版本的python解释器即可。

web.config 设置：

<appSettings> 
  <add key="WSGI_HANDLER" value="myApp.wsgi.application"/> 
  <add key="PYTHONPATH" value="D:\home\site\wwwroot"/> 
  <add key="WSGI_LOG" value="D:\home\LogFiles\wfastcgi.log"/> 
  <add key="PYTHONPATH" value="D:\home\site\wwwroot" /> 
  <add key="DJANGO_SETTINGS_MODULE" value="myApp.settings" /> 
</appSettings>

希望对你有帮助。
