flask在 iis中部署

还参照了：

复制wfastcgi.py文件到项目根目录

用pip装上wfastcgi模块

flask在 iis中部署

重要的一步来了，去python下site-package目录

flask在 iis中部署

执行 wfastcgi-enable 也会生成

flask在 iis中部署

红框中是执行wfastcgi-enable添加的。后面一个是手工添加处理程序映射来的：

勾选掉

贴一下web.config

flask在 iis中部署

就是映射生成的

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <handlers>
            <add name="FlaskFastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\python.exe|E:\site-saae-python\wfastcgi.py" resourceType="Unspecified" />
        </handlers>
    </system.webServer>
</configuration>

在微软的页面中也提到了如何IIS 部署 flask :

照搬了stackoverflow的回答，

https://stackoverflow.com/questions/58261464/how-to-host-python-3-7-flask-application-on-windows-server

以上内容：

you need to install the python,wfastcgi, and flask at your server.

You can download the python from below link:

https://www.python.org/downloads/

after installing python download the wfastcgi:

pip install wfastcgi

run the command prompt as administrator and run this command.

wfastcgi-enable

run this command to enable wfastcgi.

below is my flask example:

app.py:

from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
    return "Hello from FastCGI via IIS!"
if __name__ == "__main__":
app.run()

after creating an application to run it use below command:

python app.py

now enable the cgi feature of iis:

now open iis.
right-click on the server name and select add site.
enter the site name physical path and the site binding.
after adding site select the site name and select the handler mapping feature from the middle pane.
Click “Add Module Mapping”
add below value:

executable path value:

C:\Python37-32\python.exe|C:\Python37-32\Lib\site-packages\wfastcgi.py

Click “Request Restrictions”. Make sure “Invoke handler only if request is mapped to:” checkbox is unchecked:

Click “Yes” here:

now go back and again select the server name and select fast CGI setting from the middle pane.

Double click it, then click the “…” for the Environment Variables collection to launch the EnvironmentVariables Collection Editor:

Set the PYTHONPATH variable:

And the WSGI_HANDLER (my Flask app is named app.py so the value is app.app — if yours is named site.py it would be site.app or similar):
特别注意这里的app.py --> app.app

Click OK and browse to your site:

Note: Do not forget to assign the iusr and iis_iusrs user permission to the flask site folder and python folder.
