Flask Request Object

In this python flask guide, we are going to learn all about Python flask request objects with help of examples. In the previous, tutorial, we have seen all about how to render HTML files in the flask application.

Note:- You should have basic knowledge of Python programming to understand flask coding. You can learn Python from our Python tutorial.

Flask Request Object

As we know that all web applications are based on the client-server architecture. The flask request object is capable of getting all the information sent from the client to the server.
As we discussed in our previous tutorial, Every request performs on the basis of HTTP methods.

Let’s understand the flask request object with the help of an example.

Retrieve form data

In this flask example, we will get all the form data using the flask request object.


Flask website

<h1>User Registration Form</h1>

<form method="POST" action="/success">
<label>Username:- </label>
<input type="text" name="username" placeholder="Enter your username"><br><br>
<label>Email:- </label>
<input type="email" name="email" placeholder="Enter your email"><br><br>
<label>Password:- </label>
<input type="password" name="password" placeholder="Enter your password">
<button type="submit">Submit</button>

from flask import Flask, render_template, request

#Create the object of the Flask class.
app= Flask(__name__)

def Home():
    return render_template("users.html")
@app.route("/success", methods=['POST'])    
def success():
    user = {}
    username = request.form['username']
    email = request.form['email']
    password = request.form['password']
    user.update({"username": username, "email": email,"password":password})
    return user

if __name__ == '__main__':

When you execute the above flask script file and visit then it will ask you to fill the form and submit it. After submitting the form you will all the data which have filled up in the form.
