Web Server Using Python

How to create a web server using Python in Odinub

Here we will use Python web framework called Flask to create a dynamic web server in Odinub. Flask provides you with the tools, libraries and technologies that allow you to build a web application. thie web application can be some web pages, web server, a blog or a commercial website.

Step 0: WiFi setup

For setup the WiFi on your odinub board follow our another article

Step 1: Install Flask

In order to install Flask we will need to have pip install. It can be installed by following commands.

sudo apt-get install python-pip

After installing pip we can use it to install Flask and its dependencies.

sudo pip install Flask

Step 2: Python Script

To test the installation create a new file called hello_odinub.py using this command.

sudo nano hello_odinub.py

Type this code in newly open window.

From flask import  Flask
App=Flask(__name__)
@app.route(“/”)
Def hello():          
    Return “Hello!! its Odinub”
If __name__ == “__main__”:         
    App.run(host=”0.0.0.0”,port=80,debug=True) 

Step 3: Get the IP address

We have to replace 0.0.0.0 with the IP address of Odinub. This IP address can be known by the following command.

ifconfig wlan0 

Step 4: Run the Python script

Now enter the following command to run the web server.

sudo python hello_odinub.py

Step 5: Open the web server

Now open the web browser any type the following link.

http://0.0.0.0:80/

This is the small taste of what you can do with python and Flask. I hope this project helps you in your IoT applications as it creates the web server on local network and helps you to find your way into exciting world of electronics.
