Windows 10 IIS URL Error - Python Flask Rest API

Question

This is my sample python rest API application. I have hosted this application on Windows 10 IIS.

hello.py

from flask import Flask
app=Flask(__name__)

@app.route('/',methods=['GET'])
def index():
    return "Hello World 0.0!"
    
@app.route('/1',methods=['GET'])
def index1():
    return "Hello 1.0!"

@app.route('/2',methods=['GET'])
def index2():
    return "Hello 2.0!"
    
if __name__=='__main__':
    app.run(debug=True)

web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="FlaskFastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="C:\Program Files\Python39\python.exe|&quot;C:\Program Files\Python39\lib\site-packages\wfastcgi.py&quot;" resourceType="Either" requireAccess="Script" />
    </handlers>
    <security> 
        <requestFiltering allowDoubleEscaping="true"></requestFiltering> 
    </security> 
  </system.webServer>

  <appSettings>
    <!-- Required settings -->
    <add key="WSGI_HANDLER" value="hello.app" />
    <add key="PYTHONPATH" value="~/" />

    <!-- Optional settings -->
    <add key="WSGI_LOG" value="C:\website\oboeqa_web.log" />
    <add key="WSGI_RESTART_FILE_REGEX" value=".*((\.py)|(\.config))$" />
  </appSettings>
</configuration>

http://localhost:8080

Hello World 0.0!

http://localhost:8080/1

HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

http://localhost:8080/2

HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

http://localhost:8080/3

HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

The first route only works and the remaining route not working.

Answer 1

You need to modify the resourceType:

    <handlers>
      <add name="FlaskFastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="C:\Python27\python.exe|C:\Python27\lib\site-packages\wfastcgi.pyc" resourceType="Unspecified" requireAccess="Script" />
    </handlers>

You need to modify the value of resourceType to Unspecified.
