使用Visual Studio在Azure上部署python flask项目 [英] deploying python flask project on azure using visual Studio

问题描述

我在将Py项目部署到Azure时遇到了一些麻烦。
我得到的消息是
该页面无法显示，因为发生了内部服务器错误。

我知道这是配置错误在项目中。
我的web.config文件具有以下内容。

Python已安装在Azure Web服务的D中，并且在运行本地计算机
的C中Py2.7

应用名称为白板

本地主机上的端口5965 ...

我在做什么错？ MS文档没有帮助

解决方案

根据我的经验，您的问题是由软件包引起的 web.config 中丢失或路由错误。（或者您可以在 wfastcgi.log 中找到日志）我确实测试成功，请参考我的工作步骤：

在

第2步：发布您的烧瓶项目，并添加 web.config 。

web.config：

 <？xml version = 1.0 encoding = utf-8？> 
< configuration> 
< appSettings> 
<添加密钥= WSGI_HANDLER value =<您的项目名称> .app /> 
< add key = PYTHONPATH value = D：\home\site\wwwroot /> 
<添加密钥= WSGI_LOG value = D：\home\LogFiles\wfastcgi.log /> 
< / appSettings> 
< system.webServer> 
< handlers> 
< add name = PythonHandler path = * verb = * modules = FastCgiModule scriptProcessor = D：\home\Python364x64\python.exe | D：\home＼ ＼Python364x64\wfastcgi.py resourceType = Unspecified requireAccess = Script /> 
< / handlers> 
< /system.webServer> 
< / configuration> 
  

第3步：切换到Kudu CMD并命令 cd Python361x64 和 touch get-pip.py 并复制网址 https://bootstrap.pypa.io/get-pip的内容.py 通过编辑按钮插入 get-pip.py ，然后运行 python get-pip.py 安装pip工具。

第4步：安装所需的任何软件包通过 python -m pip安装Flask

希望它对您有帮助。有任何问题，请告诉我。

I am having some trouble getting my Py project to be deployed on Azure. The message I get is "The page cannot be displayed because an internal server error has occurred."

Which I know is a config error in the project. My web.config file has the below.

Python is installed in D in my azure web service and in C in my local machine running Py2.7

Appname is whiteboard

port 5965 on local host...

What am I doing wrong?? MS documentation did not help

<configuration>
    <appSettings>
    <add key="WSGI_HANDLER" value="whiteboard.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="*" verb="*" modules="FastCgiModule" scriptProcessor=" D:\home\Python27\python.exe|D:\home\Python27\wfastcgi.py"
        resourceType="Unspecified" requireAccess="Script"/>
    </handlers>
    <httpPlatform processPath="C:\Python27\python.exe"
    arguments="F:\FYP-Whiteboard\Whiteboard\whiteboard\runserver.py %HTTP_PLATFORM_PORT%5"
    stdoutLogEnabled="true"
    stdoutLogFile="F:\FYP-Whiteboard\Whiteboard\whiteboard\LogFiles\python.log"
    startupTimeLimit="60"
    processesPerApplication="16">
    <environmentVariables>
        <environmentVariable name="SERVER_PORT" value="5965" />
        <environmentVariable name="PYTHONPATH" value="D:\home\site\wwwroot" />
        <environmentVariable name="PORT" value="%HTTP_PLATFORM_PORT%" />
    </environmentVariables>
    </httpPlatform>
    </system.webServer>
    </configuration>

解决方案

Per my experience, your issue is resulted from the package missing or route error in web.config.(Or you could find log in wfastcgi.log) I did test successfully, please refer to my working steps:

As you found in the Managing Python on Azure App Service , Azure App Service provide you with a site extension. You could install packages on KUDU console.

Step 1 : Create azure web app and add Extensions(here is Python 3.6.4 x64)

Step 2 : Publish your flask project and add the web.config.

web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <add key="WSGI_HANDLER" value="<Your Project Name>.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="*" verb="*" modules="FastCgiModule" scriptProcessor="D:\home\Python364x64\python.exe|D:\home\Python364x64\wfastcgi.py" resourceType="Unspecified" requireAccess="Script"/>
    </handlers>
  </system.webServer>
</configuration>

Step 3: Switch to the Kudu CMD and commands cd Python361x64 and touch get-pip.py and copy the content of the url https://bootstrap.pypa.io/get-pip.py into the get-pip.py via Edit button, then run python get-pip.py to install the pip tool.

Step 4 : Install any packages you need via python -m pip install Flask

Hope it helps you. Any concern ,please let me know.
