博客系统 实现 （前端 + 后端 ）代码

由于您的问题没有提供具体的技术栈或者编程语言，我将提供一个使用流行的Python后端（Flask）和Vue.js前端的简单博客系统的示例。

后端（使用Flask）:

from flask import Flask, request, jsonify
from flask_sqlalchemy import SQLAlchemy
 
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///blog.db'
db = SQLAlchemy(app)
 
class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(80), unique=True, nullable=False)
    content = db.Column(db.Text, nullable=False)
 
    def __repr__(self):
        return f"Post('{self.title}', '{self.content}')"
 
@app.route('/api/posts', methods=['GET'])
def get_posts():
    posts = Post.query.all()
    return jsonify({'posts': [post.title for post in posts]})
 
@app.route('/api/posts', methods=['POST'])
def create_post():
    title = request.json.get('title')
    content = request.json.get('content')
    post = Post(title=title, content=content)
    db.session.add(post)
    db.session.commit()
    return jsonify({'message': 'Post created successfully', 'post': post.title}), 201
 
if __name__ == '__main__':
    db.create_all()
    app.run(debug=True)

前端（使用Vue.js）:

<template>
  <div>
    <input v-model="title" placeholder="Title">
    <textarea v-model="content" placeholder="Content"></textarea>
    <button @click="createPost">Create Post</button>
    <ul>
      <li v-for="post in posts" :key="post">{{ post }}</li>
    </ul>
  </div>
</template>
 
<script>
export default {
  data() {
    return {
      title: '',
      content: '',
      posts: []
    };
  },
  created() {
    this.fetchPosts();
  },
  methods: {
    fetchPosts() {
      fetch('/api/posts')
        .then(response => response.json())
        .then(data => {
          this.posts = data.posts;
        });
    },
    createPost() {
      fetch('/api/posts', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({ title: this.title, content: this.content })
      })
        .then(response => response.json())
        .then(data => {
          this.posts.push(this.title);
          this.title = '';
          this.content = '';
          alert(data.message);
        });
    }
  }
};
</script>

这个简单的示例展示了如何使用Flask作为后端和Vue.js作为前端创建一个RESTful API驱动的博客系统。后端提供了创建帖子和获取帖子列表的
