How to analyze the modularization in web development 7, I believe that many inexperienced people do not know what to do about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Data return in json format is supported:

Example:

There is a problem. The web page is not in json format.

Def jsonify (* * kwargs):

Content = json.dumps (kwargs)

# response = Response ()

# response.content_type = "application/json"

# response.body ='{} '.format (content) .encode ()

# return response

Return Response (body=content, status='200 OK', content_type='application/json', charset='utf-8')

@ py.register_postinterceptor

Def showjson (ctx, request, response):

Body = response.body.decode ()

Return jsonify (body=body)

Modularity:

1. Familiar with the programming interface of wsgi

2. Strengthen the idea of modularization and class encapsulation.

3. Enhance the ability to analyze business

In addition, permission verification and SQL injection detection functions use interceptor filtering

VER1:

New-- > Python Package,webtest, put the code in the _ _ init__.py file, and change the Application class to the WebTest class

Import webtest

Webtest. # after this adjustment, in this way, a lot of things are external.

VER2:

Webtest/ {web.py, _ _ init__.py}

1. Put the code after the WebTest class into _ _ init__.py

2. In the WebTest class, add:

Class WebTest:

Router = _ Router # exposes the class in the form of class attributes, as implemented by many basic classes

Request = Request

Response = Response

From webtest import WebTest

WebTest. # in this way, you can access the _ Router class, Requst class and response class in web.py

Publish:

Example:

From distutils.core import setup

Setup (name='webtest'

Version='0.0.1'

Description='wsgiref web test'

Author='jowin'

Author_email='jowin@163.com'

Url=' https://blog.51cto.com/jowin',

Packages= ['webtest'] # packing list, specifying that' webtest' will package all non-catalog submodules in webtest

)

Pip install webtest-0.0.1.zip # is installed on other hosts

VER3:

1. Create a new python package,webtest2/ {web.py,__init__.py}

2. Put all the code into web.py

2. Write only in _ _ init__.py:

From. Web import Application # package uses its own relative path. Webtest2 this package exposes only Application. The package is encapsulated for you through Application. Indirect access

On the left side of pycharm after pip install webtest-0.0.2.zip # installation, there is a conflict between the working directory webtest2 and External Libraries/site-packages/webtest2, but there is a search order; alternatively, the working directory webtest2 can be copied directly to other hosts to run
