How to Test the Script

I have used the python command that comes with MacOS. The version is 2.7.16. For Linux, use a package manager like apt or yum to install python in case you do not have one. I used 2.7.12 that came with Ubuntu 16.04. You also need the pip command.

1. Follow the instruction on the Flask website to install Flask framework. It is up to you whether to use venv. I do not.
2. Create a directory and myapp.py inside it, or you can copy the file from this git folder.

$ mkdir myapp
$ cd myapp
$ vi myapp.py

3. Run the program.

$ chmod +x myapp.py
$ ./myapp.py 
 * Serving Flask app "myapp" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 392-403-575

4. Open another terminal, go into the same myapp directory, and run the test script.

$ ./test.sh
Hello Taro

5. The Flask framework will print access log to the terminal where it is running.

$ ./myapp.py
