Route

• Receives URL patterns and executes registered Python methods when requests come in for URLs matching those patterns

  • Finding handler methods to process through URLs like this is called URL Routing!

  • To generate corresponding URLs in handlers, use the url_for method

flask route example

• Flask routes are connected to Python functions

• Use the @app.route() decorator to connect URLs and functions

  ex)

  @app.route('/hello')
  def hello_world():
     return "hello world!!!!"

flask route params

• You can create routes with parameters

• You can pass string and number types as parameters

  ex)

  string parameter

  @app.route('/member/<name>')
  def get_member(name):
    return "Thank you for joining us " + str(name)

  number parameter

  @app.route('/sale/<transaction_id>')
  def get_sale(transaction_id=0):
    return "The transaction is "+str(transaction_id)

flask route multiple arguments

• You can also create flask routes with multiple parameters

  ex)

  @app.route('/create/<first_name>/<last_name>')
  def create(first_name=None, last_name=None):
    return 'Hello ' + first_name + ',' + last_name
