Data Handling Using the Request Object

Data Handling Using the Request Object

In this lesson, we will handle the POST request received by the login template and retrieve the data from it.

We'll cover the following...

📌 How can we know if a particular request is GET or POST?
This is where the request object comes in handy. Let’s find out more about the request object.

Accessing form data

To access the data sent by a user, we use the global request object. Before we start using it, let’s import it from the flask module.

from flask import request

Getting the Method type from request

We can use the method member variable of the request object to determine the method of an incoming request.
Consider the snippet given below.

@app.route("/login", methods=["GET", "POST"])
def login():
    if request.method == "POST":
        ...
    else
        ...
    return render_template("login.html")
