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

interface, so we can focus on a function to process a URL. As for the URL-to-function mapping, it is given to the web framework. Because it is easy to develop a web framework in Python, Python has hundreds of open-source web frameworks. Here we do not discuss the advantages and disadvantages of various web frameworks, directly choose a more popular web framework--flask to use. Writing a web App with flask

Flask provides a signal (signals) function, which is a message distribution mechanism. Similar to hooks (Hooks). Using the signal function can reduce the coupling of the program and decompose the complex business model. For example, after updating the product data, you can send a signal. When there is a function to process the product data, the signal can be captured for processing. For example, to create a product cache, or to update the search index
