Use the Python Flask framework to construct the structure example of a large Web application, pythonflask Although small web applications can be easily expanded with a single script, this method cannot be well expanded. As the application becomes more complex, processing in a single large source file becomes more and more problematic. Unlike most other web frameworks, Flask does not have a specific way of o

Docker In this article, I'll try to demonstrate a viable way to develop Python applications (primarily web apps) with Docker. While I am myself focused on Python's flask micro-framework, the purpose of this article is to demonstrate how to better develop and share applications through Docker (applications developed by any language and framework). By encapsulating dependencies, Docker significantly reduces the gap between the development environment

This tutorial details how to verify their email address during the user registration process. On the workflow, a confirmation letter will be sent to the user after registering for a new account. Until the user has completed the "verification" in the message, their account will remain in an "unverified" state. This is the workflow that most Web applications use. One of the important things about this is what permissions do unauthenticated users have? Or do they have full access to your app, or a

In Fask, you can deploy multiple subdomains by using wildcard subdomains. here we will explain how to configure multiple subdomains in a Python Flask framework. For more information, see Flask subdomain name It is generally used for a small number of subdomain names. a module corresponds to a subdomain name. Let's take a look at the following example: Modules. py: from

Step 2: Make sure that python is installed on the local machine. Download easy_install to a local directory and double-click ez_setup.py. python will be automatically downloaded to the python installation directory/Scripts, then add the directory where easy_install is located in the PATH of the system environment variable, for example, C: \ Python27 \ Scripts. Step 2: Install virtualenv, which is mainly used to isolate the interpreter environment and avoid multiple python or multiple python libr

. However, if a duplicate nickname appears, subsequent users will not be able to register successfully. What's worse, we allow users to arbitrarily change their nicknames in a user-configured form, but we still don't check the nickname conflicts. When we analyze the behavior of the application after the error is generated, we will locate these problems. Flask Debugging Features So let's see what happens when a bug is triggered. Let's start by crea
