The blueprint of flask complements openpyxl

Because our current project development is a relatively time-consuming and energy-consuming project , If we take all Flask If all the request methods are written in the same file , It is very inconvenient for us to manage the code and add the function code later
        The following example ： We write multiple routes in one file , This makes code maintenance difficult .

        As shown in the figure , If we write all the request methods under the same processing file , It makes our code look illogical , If we want to modify the code or add new code later , It would be embarrassing , I don't know how to do it , At this point, we need our so-called blueprint to solve this problem , If you've learned django Of programmers may have known django Medium app The role of the , you 're right ,django Medium app The main function of will be django The project is divided into individual app, And then put all the app Assign different processing functions , They are connected into a large by routing assignment django project , Actually Flask Blueprints and django Medium app The function is the same , Let's have a general understanding of Flask The blueprint of , The code is as follows

        We first create a master routing profile manage.py, The main function of this file is to start the whole Flask frame （ project ）, As shown in the figure

        next , We are manage.py Create two files in the same directory as admin.py    user.py, Let's take a look at the contents of the two files

 

      These two files are equivalent to django Two of them app 了 , The difference is django The route assignment in is to pass large routes through include Assigned to app Of urls.py, and Flask It is to add blueprints to the master by means of blueprint registration app in ,user.py,admin.py The main task in is to create blueprints , Then you can add some routing configurations to the created blueprint , Then we can create the main routing file manage.py Register the blueprint we created with the master app It's in .

        In this way, after we have configured it, we can realize our hierarchical routing management , So let's try that , Run the main program manage.py

        We access the route we set in the browser

      The route we requested is the same as the return value we set , In this way, we have roughly completed a Flask Registration of blueprints for , Realize the hierarchical management of file function .
