Question

How can I code the following using Python 3.6 and Flask? If you could give me some examples I would appreciate it. Create the following Routes in a Flask Application Default Route ("/") - Go to a simple html template page that tells about data. GET ("/item") - Will return UP TO 1000 items from the data. GET ("/item/") - Will return a single item from the data, by ID. DELETE("/item/") - Will delete a single item (again, you will need a unique column name) POST ("/item") - As opposed to GET, POST will create a new item in your database. The body of the request will contain the item to be added.

Explanation / Answer

by using the Flask-REST Service, we can Write API Calls which are carried by Simple HTTP Protocols and are very Light Weight. In order to do so in Python, we have to Import Flask and use it within our coding where ever necessary. here in this by default, Flask Provides us the Resource Base Class that define for the Routing of more than one HTTP methods given to an URL. these methods can be identified by the HTTP Verbs GET, POST, PUT, DELETE.

this is how we install Flask in Ubuntu Linux

Now I am creating a file with name app.py with the code

Now I am defining the tasks to do for the specific operation like Get or Post or Put or Delete

Now for Validating the Request along with URL, Header Content, this code explains how it parses the Url and make a route to get into specific Method Defined.

We can use Request parser Class for the Parsing given by the Flask (just like argparse)

Now I am defining the PUT method for which the Resource needs to be initialized.

Now for generating the Responses for specific method, I can use Jsonify helper function.

or

here we can do "make public task" wrapper from original Server converted to the internal representation to external as the client expected. this Conversion includes the removing of id field and adding in the URI Field make flask to parse its response in a much easier way.
