Flask Request Object
- In the client-server architecture, the request object contains all the data that is sent from the client to the server.
- Now we will discuss the Request object and its important attributes
- Form : Contains the key-value pair of form parameters and their values.
- Args : It is the part of the URL which is specified in the URL after question mark (?).
- Cookies : It is saved at the client-side to track the user session.
- Files: It contains the data related to the uploaded file.
- Method: It is the current request method (get or post).
Form data retrieval on the template
- The data filled in this form is posted to the /success URL which triggers the print_data() function.
- print_data() collects all the data from the request object and the renders the result_data.html file which shows all the data on the web page.

script.py
from flask import *
app = Flask(__name__)
@app.route('/')
def customer():
return render_template('customer.html')
@app.route('/success',methods = ['POST', 'GET'])
def print_data():
if request.method == 'POST':
result = request.form
return render_template("result_data.html",result = result)
if __name__ == '__main__':
app.run(debug = True)
