How to implement website content management and publishing system through Webman
Webman is a Web framework developed based on Python language, which provides many powerful tools and plug-ins , which includes a user-friendly content management and publishing system. In this article, we will introduce how to use Webman to build a simple website content management and publishing system, and illustrate the implementation process through code examples.
- Install Webman
First, we need to install Webman. Install Webman from the command line using the following command:
pip install webman
- Creating a Web Application
Next, we will create a web application. Use the following code to create a file named app.py:
from webman import Webman
app = Webman()
@app.route('/')
def index(request, response):
response.text = 'Hello Webman!'
if __name__ == '__main__':
app.run() This code creates a web application named app and places it in the root path ( '/') defines a processing function. In this processing function, we set the text property of the response object to 'Hello Webman!', indicating that the text will be returned to the user as a response.
- Run the Web application
After saving the app.py file, use the following command to run the Web application:
python app.py
Open browsing browser and enter http://localhost:8000 in the URL address bar, you will see a page showing 'Hello Webman!'.
- Create website content management page
Now, we will create a page for managing website content. Update the app.py file with the following code:
from webman import Webman
from webman.middleware import SessionMiddleware
app = Webman()
app.use(SessionMiddleware())
@app.route('/')
def index(request, response):
response.text = 'Hello Webman!'
@app.route('/admin')
def admin(request, response):
session = request.session
if session.get('logged_in'):
response.text = 'Welcome to the admin page!'
else:
response.redirect('/login')
@app.route('/login')
def login(request, response):
session = request.session
if request.method == 'POST':
username = request.params.get('username')
password = request.params.get('password')
if username == 'admin' and password == 'password':
session['logged_in'] = True
response.redirect('/admin')
else:
response.redirect('/login')
else:
response.send_file('login.html')
if __name__ == '__main__':
app.run() In this code, we have introduced the SessionMiddleware middleware for managing user sessions. At the same time, we created 3 processing functions for displaying the homepage, administrator page and login page respectively. In the implementation, we use the request.session object to store user session information, and determine whether to display the administrator page by determining whether the user is logged in.
Note that here we use a simple username and password for login authentication. In practical applications, for security reasons, we should use more stringent and complex authentication methods.
- Create a login page
In order to implement the login function, we need to create a login page. Create a file called login.html in the project root directory and add the following code to the file:
<!DOCTYPE html> <html> <body> <h2>Login</h2> <form method="post" action="/login"> <label for="username">Username:</label><br> <input type="text" id="username" name="username"><br> <label for="password">Password:</label><br> <input type="password" id="password" name="password"><br><br> <input type="submit" value="Submit"> </form> </body> </html>
This HTML code creates a simple login form, form The action attribute points to the URL address of the login processing function, and the method attribute is post. After the user enters their username and password in the login form and clicks the submit button, the form data will be sent to the login handler function. The login handler will authenticate based on the username and password, and upon successful authentication, set the user session to the logged in state.
- Run the web application
After saving the app.py and login.html files, use the following command to run the web application :
python app.py
Open the browser and enter http://localhost:8000 in the URL address bar, you will see the page showing 'Hello Webman!'. Click the 'Login' link on the page to enter the login page. Enter the user name 'admin' and the password 'password', and click the Submit button. If the username and password match, you will be redirected to the admin page with the 'Welcome to the admin page!' message.
Through the above steps, we successfully built a simple website content management and publishing system using Webman. Using similar methods, we can also add more functions to the website, such as creating, editing and deleting pages, uploading and managing files, and more.
