In this Flask online course, we will be discussing the redirect in Flask.
Flask is a Python web framework that has been used for almost everything from simple single-page applications, API backends, and even full-stack web frameworks. It’s easy-to-use and flexible enough for beginners to get started with without getting overwhelmed.
Redirects are a way to change the URL of a given resource. It is usually used when the resource does not exist on the server you are working on.
There are three types of redirects in Flask: permanent, temporary, and conditional.
Permanent Redirect: A permanent redirect is one that changes the URL without changing the page content or anything else about it. This is often used when a URL has been moved or has been changed in some way that you cannot use mod_rewrite to fix.
Temporary Redirect: A temporary redirect is one that changes only the URL without changing anything else about it. This type of redirect can be useful for things like 404 errors and other situations where you want to show a different page for a short period of time before returning back to normal.
Conditional Redirect: A conditional redirect is one that changes the URL but also changes the page content. This type of redirect will only work if a certain condition is met.
There are three ways to use redirect in Flask:
1) Using the "return" statement
2) Using decorators
3) Using app.get_response() function
When you use the redirect function, you are telling your app to take a different route. In this example, it will take the user to a different page.
The redirect function is very useful in Flask because it allows you to tell your app which URL it should go to when a certain action is performed by an end-user.
Redirects are also useful for managing URLs in your application. They allow you to change URLs as well as add and remove them from the list of routes that your app uses in an efficient and easy way.
