Webman is a web development framework based on the Python language, which provides a simple, fast and scalable way to build web applications. This article will introduce how to use the Webman framework to implement content management and publishing functions, and give corresponding code examples.

1. Install the Webman framework

First, we need to install the Webman framework. You can install it using pip with the following command:

pip install webman

2. Create a Web application

Before we start, we need to create a Web application. You can create an empty web application structure by using the following command:

webman new myapp

This command will create a folder named myapp in the current directory and generate some initial files in it.

3. Write the content management page

Create a new content management page:
Create a file named content.html in the myapp folder, For example:

<!DOCTYPE html>
<html>
<head>
 <title>内容管理</title>
</head>
<body>
 <h1>内容管理</h1>
 <form action="/save" method="POST">
     <label for="title">标题：</label>
     <input type="text" id="title" name="title" required><br><br>
     <label for="content">内容：</label>
     <textarea id="content" name="content" required></textarea><br><br>
     <input type="submit" value="保存">
 </form>
</body>
</html>

This page contains a form where the user can enter a title and content and click the save button to submit the form.

Create a route for saving content:
In the routes.py file under the myapp folder, add the following code:
```
from webman.route import post

@post('/save')
def save_content(request):
 title = request.form.get('title')
 content = request.form.get('content')
 
 # 将标题和内容保存到数据库或其他介质中
 
 return '保存成功！'
```
This code definition A post type route is created. When the user submits the form, the save_content function will be executed to process the request. Get the title and content entered by the user in the function and save it to the database or other media.

4. Start the Web application

Start the Web application:
Enter the myapp folder on the command line and execute the following Command:
```
webman run
```
This command will start the web application and listen to the default port (usually 5000). The content management page can be accessed by visiting http://localhost:5000/content.
Configure routing:
If you want to modify the default port or configure other routes, you can configure it in the config.py file under the myapp folder. For example, you can add the following code to change the default port to 8000:
```
port = 8000
```
You can add the following code to configure other routes:
```
routes = [
 ('/content', 'content.html'),
 ('/save', 'save_content'),
]
```
The above code points the /content route to the content.html page, and / The save route points to the save_content function.

So far, we have completed the installation and configuration of the Webman framework and implemented simple content management and publishing functions. As can be seen from this example, the Webman framework is very simple to use and has good scalability. Its powerful functions can be further developed according to actual needs.
