用python和vue生成一个用户管理系统

好的，这里提供一个简单的用户管理系统示例，使用Python Flask作为后端和Vue.js作为前端。

后端部分（Python Flask）：

1. 创建一个虚拟环境并安装Flask：

python3 -m venv env
source env/bin/activate
pip install Flask

2. 创建一个名为app.py的Flask应用程序：

from flask import Flask, jsonify, request

app = Flask(__name__)

users = [
    {"id": 1, "name": "John Doe", "email": "john@example.com"},
    {"id": 2, "name": "Jane Doe", "email": "jane@example.com"}
]

@app.route('/users', methods=['GET'])
def get_users():
    return jsonify(users)

@app.route('/users', methods=['POST'])
def create_user():
    user = {
        "id": len(users) + 1,
        "name": request.json['name'],
        "email": request.json['email']
    }
    users.append(user)
    return jsonify(user)

@app.route('/users/<int:user_id>', methods=['GET'])
def get_user(user_id):
    user = next((user for user in users if user["id"] == user_id), None)
    return jsonify(user)

@app.route('/users/<int:user_id>', methods=['PUT'])
def update_user(user_id):
    user = next((user for user in users if user["id"] == user_id), None)
    if user:
        user.update(request.json)
        return jsonify(user)
    else:
        return jsonify({"error": "User not found"}), 404

@app.route('/users/<int:user_id>', methods=['DELETE'])
def delete_user(user_id):
    user = next((user for user in users if user["id"] == user_id), None)
    if user:
        users.remove(user)
        return jsonify({"message": "User deleted successfully"})
    else:
        return jsonify({"error": "User not found"}), 404

if __name__ == '__main__':
    app.run(debug=True)

3. 运行应用程序：

python app.py

前端部分（Vue.js）：

1. 安装Vue CLI：

npm install -g @vue/cli

2. 创建一个名为user-management的Vue项目：

vue create user-management

3. 安装axios和bootstrap-vue：

cd user-management
npm install axios bootstrap-vue

4. 编辑src/App.vue文件，添加以下代码：

<template>
  <div class="container">
    <h1>User Management</h1>
    <form @submit.prevent="createUser">
      <div class="form-group">
        <label for="name">Name:</label>
        <input type="text" class="form-control" id="name" v-model="newUser.name">
      </div>
      <div class="form-group">
        <label for="email">Email:</label>
        <input type="email" class="form-control" id="email" v-model="newUser.email">
      </div>
      <button type="submit" class="btn btn-primary">Create User</button>
    </form>
    <hr>
    <div class="row">
      <div class="col-sm-4" v-for="user in users" :key="user.id">
        <div class="card">
          <div class="card-body">
            <h5 class="card-title">{{ user.name }}</h5>
            <p class="card-text">{{ user.email }}</p>
            <button class="btn btn-primary" @click="editUser(user)">Edit</button>
            <button class="btn btn-danger" @click="deleteUser(user)">Delete</button>
          </div>
        </div>
      </div>
    </div>
    <b-modal v-model="showModal" title="Edit User">
      <form @submit.prevent="updateUser">
        <div class="form-group">
          <label for="name">Name:</label>
          <input type="text" class="form-control" id="name" v-model="currentUser.name">
        </div>
        <div class="form-group">
          <label for="email">Email:</label>
          <input type="email" class="form-control" id="email" v-model="currentUser.email">
        </div>
        <button type="submit" class="btn btn-primary">Save</button>
      </form>
    </b-modal>
  </div>
</template>

<script>
import axios from 'axios'
import { BModal } from 'bootstrap-vue'

export default {
  name: 'App',
  components: {
    BModal
  },
  data () {
    return {
      users: [],
      newUser: {
        name: '',
        email: ''
      },
      currentUser: {
        id: null,
        name: '',
        email: ''
      },
      showModal: false
    }
  },
  created () {
    this.getUsers()
  },
  methods: {
    getUsers () {
      axios.get('http://localhost:5000/users')
        .then(response => {
          this.users = response.data
        })
        .catch(error => {
          console.log(error)
        })
    },
    createUser () {
      axios.post('http://localhost:5000/users', this.newUser)
        .then(response => {
          this.users.push(response.data)
          this.newUser = {
            name: '',
            email: ''
          }
        })
        .catch(error => {
          console.log(error)
        })
    },
    editUser (user) {
      this.currentUser = { ...user }
      this.showModal = true
    },
    updateUser () {
      axios.put(`http://localhost:5000/users/${this.currentUser.id}`, this.currentUser)
        .then(response => {
          const index = this.users.findIndex(user => user.id === this.currentUser.id)
          this.users[index] = response.data
          this.currentUser = {
            id: null,
            name: '',
            email: ''
          }
          this.showModal = false
        })
        .catch(error => {
          console.log(error)
        })
    },
    deleteUser (user) {
      axios.delete(`http://localhost:5000/users/${user.id}`)
        .then(response => {
          const index = this.users.findIndex(u => u.id === user.id)
          this.users.splice(index, 1)
        })
        .catch(error => {
          console.log(error)
        })
    }
  }
}
</script>

<style>
.container {
  margin-top: 50px;
}
</style>

5. 运行应用程序：

npm run serve

现在您应该可以在http://localhost:8080中看到用户管理系统了！
