Building REST API

Installing Requirements:

For this lab, We only need Flask library and jsonify which can be simply installed by writing their pip commands.

Now, Let's start making our API

Creating a basic Flask Web app:

First, We will import Flask and initialise the app. Then we write the default if condition.

For this lab, We will be making an API that shows a collection of the top 100 IMDB movies and user can search using rank to find the movie and their respective IMDB id.

So, let's define the default route as follows:

To test this, We can simply open a terminal/command prompt/powerShell in the same directory and write:

python "filename".py runserver

In my case file name is app.py so the command will be:

python app.py runserver

We can also directly run the code in the IDE itself.

After running this command it will show us the server on which our app is running:

* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

In this case, the server is http://127.0.0.1:5000/

If we paste this link on our browser, We will get the following output:

As we have set debug = True, We will be notified about any mistakes or syntax errors in our code.
