无法在Azure-web.config上部署基本的Python 3.6？

时间：2019-04-29 11:43:25

标签： python azure web-config

我目前正在向Azure发布一个非常基本的Flask应用程序，尽管我在Google上发现了很多东西，但已经有好几天没有成功了。

我的体系结构非常简单（我将在下面显示它，因为我认为这不是问题的根源），并且我有一个web.config文件：

文件“ web.config”：

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="WSGI_HANDLER" value="MentorQuestFlask.app"/>
    <add key="PYTHONPATH" value="D:\home\site\wwwroot"/>
    <add key="WSGI_LOG" value="D:\home\LogFiles\wfastcgi.log"/>
  </appSettings>
  <system.webServer>
    <handlers>
      <add name="PythonHandler" path="handler.fcgi" verb="*" modules="FastCgiModule" scriptProcessor="D:\home\python364x64\python.exe|D:\home\python364x64\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>

在Azure中，我添加了扩展名：Python 3.6.4 x64 同样在另一个线程之后，我在配置选项卡中添加了Python 3.6：picture of the configuration zone

还在“路径映射”中添加了：

扩展名：fastCgi

脚本处理器：D：\ home \ python362x86 \ python.exe

参数：D：\ home \ python362x86 \ wfastcgi.py

最后在应用程序设置中，WEBSITE_USE_PLACEHOLDER设置为0。

但是没有任何效果。在网站上，我看到以下错误：

“由于发生内部服务器错误，因此无法显示该页面。”

所以我用Kudu来显示以下内容（在文本下方）

我的问题是：

  1. 似乎没有安装任何软件包（烧瓶错误）
  2. web.config似乎配置不正确。

我尝试了几种不同的配置，但是都没有用，而且我的想法还不够...

感谢您的帮助或建议吗？

此致

答案 0 :(得分：0)

我已经解决了我的问题

为清楚起见，我不确定第一部分中的错误，因为我从根本上更改了代码。自从我一直在寻找几天以来，我就提出了自己的解决方案，这可能会对某人有所帮助。我不了解下面的所有内容，但是它可以正常工作，因此我将继续基于此结构

所以：

  1. 我还有Python插件

  2. 我已使用教程将“ runserver.py”文件切换到下面：

    导入操作系统 从女服务员进口服务 从MentorQuestFlask导入应用程序

    serve（app，host =“ 0.0.0.0”，port = os.environ [“ PORT”]）

我对“ deploy.cmd”文件做了一些修改（请参见下文）

而且webconfig大大简化了：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 <system.webServer>
  <handlers>
   <add name="httpPlatformHandler" path="*" verb="*"
         modules="httpPlatformHandler" resourceType="Unspecified" />
  </handlers>

  <httpPlatform processPath="D:\home\python364x64\python.exe"
   arguments="runserver.py" requestTimeout="00:04:00" startupTimeLimit="120" startupRetryCount="3" stdoutLogEnabled="true">
   <environmentVariables>
        <environmentVariable name="PYTHONPATH" value="D:\home\site\wwwroot" />
        <environmentVariable name="PORT" value="%HTTP_PLATFORM_PORT%" />
   </environmentVariables>
  </httpPlatform>
 </system.webServer>
</configuration>
