Guide to Using Flask.make_response() in Flask 3.0
Hello! If you are working with Flask, you must realize how user-friendly and simple this web framework is for Python. Today, we aim to explain the make_response() function, which is very common for creating and returning responses in Flask applications. This function allows you to produce HTTP responses with more accuracy and specifically in scenarios that require more configurations.
First and foremost, you should know that make_response() gives you the ability to create a response that can include various items such as cookies, headers, and content. So, if you want to customize your application, do not forget about this function.
Using make_response() is quite straightforward. You can use it with a simple string, a dictionary, or even a JSON object as the response. Additionally, you can also add more features, such as specifying the HTTP status code to the response.
Now that you are familiar with the general concept of make_response(), let's start with a practical example to better understand how this function works. By looking at the code below, you can create an HTTP response using Flask.
from flask import Flask, make_response
app = Flask(__name__)
@app.route('/response')
def response_example():
# Creating a response with content
response = make_response('Hello, World!')
# Adding a custom header to the response
response.headers['X-Custom-Header'] = 'Value'
# Setting the HTTP status code
response.status_code = 200
return response
if __name__ == '__main__':
app.run(debug=True)Code Explanation
In the code above, we first import Flask and create a new application named app. Then we define a route named /response that calls the response_example function. Using make_response(), we create a new response with the content 'Hello, World!'. We also add a custom header named X-Custom-Header to the response.
Finally, we set the HTTP status code to 200 and return the response. This application can be run using app.run(debug=True).
