This article shows you an example analysis of the Django implementation of the first request, which is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Request flow of Django

Write urls.py add request routing from import viewsurlpatterns = [path ('admin/', admin.site.urls), path (' test/', views.test_path), # add the request path and the function handled by the request] write the views.py under the application directory

Increase the processing logic of the corresponding request

From django.shortcuts import render,HttpResponse # Import HttpResponse module def test_path (resquest): # function name should be consistent with the print (dir (resquest)) return HttpResponse in urls.py ("first Django request") # return properties related to the content to the page view request

Request.method-- > returns the requested method (in all uppercase): GET/POST.

Request.GET-- > getting is a parameter in URL, similar to the data structure of a dictionary

Request.POST-- > data submitted by post, similar to the data structure of a dictionary

There are three ways to return a page: `from django.shortcuts import HttpResponse, render, redirect`

HttpResponse returns a specified string

Render returns a HTML file, return render (request, 'index.html')

Redirect jumps to the corresponding URL,return redirect ('/ index/')

Send data to the page

Return render (request, 'login.html', {' error_msg': error_msg}), you can use {{variable name}} to get data on the page

test

After starting the project, the test results in the browser are as follows:
