There are different HTTP methods that we can use to make requests to the server; these methods are nothing more than a set of verbs that are used to perform different types of actions; the most common methods are GET, POST, PUT, PATCH, and DELETE:

• GET: used to get information from a web server. The information is sent in the request URL.
• POST: used to send information to a web server. The information is sent in the body of the request.
• PUT: used to update information on a web server. The information is sent in the body of the request.
• PATCH: used to partially update information on a web server. The information is sent in the body of the request.
• DELETE: used to delete information from a web server. The information is sent in the request URL.

All of these methods have their equivalent in Flask; at the moment we have used GET type methods to obtain data, but it is also possible to use others:

@app.route(<URI>, methods=('GET'))
@app.route(<URI>, methods=('POST'))
@app.route(<URI>, methods=('PUT'))
@app.route(<URI>, methods=('PATCH'))
@app.route(<URI>, methods=('DELETE'))

You can indicate several that more than one method is resolved by the same controller:

@app.route(<URI>, methods=('GET', 'POST'))

As you can see, we have a decorator function for each type of method and it has a direct relationship with the HTTP request type.
