Flask Sub Domain Generally used for a small number of sub-domain names, a module corresponding to a subdomain. Let's take a look at the following example: modules.py: From flask Import blueprintpublic = Blueprint (' public ', __name__) @public. Route ('/') def Home (): return ' Hello ' Flask ' App.py:app = Flask (_

Flask itself can directly start the HTTP server, but due to problems such as management, deployment, and performance, we generally do not use the HTTP server of Flask itself in the production environment. From the existing practices, for Flask, a better deployment method is to use uWSGI as the WSGI container and Nginx as the front-end server. The benefits of doin

This article mainly introduces a simple tutorial on using the sqlalchemy database in the Python Flask framework, which is used to connect to and operate databases in a concise manner, for more information, see sqlalchemy in flask, which is more thorough than sqlalchemy, and simpler in some methods. First import the class library: View the CODE piece derived from my CODE piece on CODE from

Installing flaskCall the PYTHON3 interpreter to create a flask virtual environment that is not available under Python version 3.4. The path to the PYTHON3 interpreter is first obtained by using the following command:which Python3Results:/library/frameworks/python.framework/versions/3.5/bin/python3Then create a flask project under the current path, named Microflask:mkdir MicroflaskCreate a

This learning note is mainly not to share experience, more is to record the experience of the Falsk process, after doing something in-depth research, because Django used longer, so many concepts are a look over, do a test to understand the function of the next flask.Flask is a jinja2 template, similar to Django's own template, but more powerful than the Django template, providing more useful tools that are basically consistent with basic usage.Wrote a small case, the basic steps of the template

Using a lot of frameworks and languages, and finally found that Python and flask are more flexible. After so many years of web development, I finally found the true love. Needless to say, write this to record their own some of the experience, first in accordance with the Mega God tutorial to turn. Some of your own experience will be added later.The installation of flask is recommended to use VIRTUALENV firs

Encyclopedia Python:python, is an object-oriented, literal translation of computer programming language; Python syntax is simple and clear, with a rich and powerful class library. It is often nicknamed the Glue language, which makes it easy to easily connect a variety of modules (especially C + +) made in other languages. A common application scenario is to use Python to quickly build a prototype of a program (sometimes even the final interface of a program), and then rewrite it in a more approp

This article illustrates how Python uses the flask framework to get a user's IP address. Share to everyone for your reference. Specifically as follows: The following code contains HTML pages and Python code, very detailed, if you are using flask, you can also learn the most basic flask usage. The Python code is as follows: From

Flask -- route there are three methods for routing flask (example: Flask. flask. route decorator (for more information about decorator, see this article). In this case, add the desired route to the parameters of the decorator. The parameter can be expressed as Flask.

Use python + flask to create an api (the source code is included in the tutorial) and pythonflask 1. Background OK. Maybe many of my friends often use various APIs like facebook, github, and even api. So many people also want to create their own APIs. There are very few tutorials on the Internet. Today I just made a try and published the method. First show the effect: Use the "curl" method to return a json value. You can also try it: curl -i http://o

Installed under Windows Flask Original address: http://blog.csdn.net/qwiwuqo/article/details/8970621Flask introductionis a lightweight Web application framework that is written using Python. Based on the Werkzeugwsgi Toolbox and the Jinja2 template engine.FlaskUse BSD licensing. Flask is also known as "microframework" because it uses a simple core and adds other features with extension.

Briefly In most of these tutorials you will spare no effort to describe how to use the database. Today we are not looking at the database, but rather to focus on another feature that is important in Web applications: How to push messages to users. In a lightweight application, we might add a mail service feature like this: When the user has a new fan, we send an email to the user. There are many ways to implement this feature, and we want to provide a reusable common framework to deal with.Fla
