Flask REST API Set up Guide for Your Flask Application

Routes are the paths or URLs through which users can interact with an API. In the event you were going to ask the waiter to show you the menu, you might use a route called /showmenu for the task. The PUT method is similar to the POST method; the only difference is that the result stays the same when the same resource is passed. For example, imagine we want to Job Postings ASP NET, C#, MVC Programmer Analyst update the restaurant’s menu with a new item. Nothing irritates me more than using a JSON API which returns HTML when an error occurs, so I was keen to put in some reasonable error handling to avoid this happening. Contains all the Flask setup code, and defines all the HTTP routes. It seems to have achieved the function we wanted, returned a JSON string.

Even though Django is older and having a slightly bigger community, Flask has its strengths. From the ground up, Flask was built with scalability and simplicity in mind. Flask applications are known for being lightweight, mainly when compared to their Django counterparts.

This type is a Python enumerator, which we still have to create, that will help us filter transactions in the future. Just like in the previous example, our application simply returns a “Hello, world!” message.

How to Create REST API Endpoints with Flask

When you do this, requests.post() automatically sets the request’s HTTP header Content-Type to application/json. It also serializes todo into a JSON string, which it appends to the body of the request. REST APIs listen for HTTP methods 16 Azure Cloud Engineer Skills for Your Career and Resume CLIMB like GET, POST, and DELETE to know which operations to perform on the web service’s resources. For an extensively documented API, see the MediaWiki Action API, which provides documentation to users who pass partial queries to the API.

  • The commands are slightly different if you use the Windows native version of Python.
  • A file that contains exactly what version of each package our project depends on, and its transitive dependencies.
  • There are two reasons to put the list into an object with a label, rather than returning the raw array.
  • And once it finds the Book, it will respond with that data.
  • This key points to all the records and is represented as an array.

Besides that, we have also changed the implementation of both methods that deal with incomes. For the endpoint used to retrieve incomes, we defined an instance of IncomeSchema to produce JSON representation of incomes. We also used filter to extract incomes only from the transactions list. In the end we send the array of JSON incomes back to users.
