Vue는 백엔드에서 제공하는 인터페이스를 어떻게 사용합니까?

<code>npm install axios</code>

<code class="js">import axios from 'axios'</code>

<code class="js">axios.get('api/todos')
  .then(response => {
    // 处理成功的响应
  })
  .catch(error => {
    // 处理请求错误
  })</code>

<code class="js">axios.post('api/todos', {
  title: '学习 Vue.js'
})
  .then(response => {
    // 处理成功的响应
  })
  .catch(error => {
    // 处理请求错误
  })</code>

<code class="js">axios.get('api/todos')
  .then(response => {
    const todos = response.data;
    // 使用 todos 数据
  })
  .catch(error => {
    // 处理请求错误
  })</code>

<code class="js">import Vuex from 'vuex'
import { createStore } from 'vuex'

const store = createStore({
  state: {
    todos: []
  },
  actions: {
    getTodos({ commit }) {
      axios.get('api/todos')
        .then(response => {
          commit('setTodos', response.data)
        })
        .catch(error => {
          // 处理请求错误
        })
    }
  },
  mutations: {
    setTodos(state, todos) {
      state.todos = todos
    }
  }
})</code>

<code class="js">import { mapState, mapActions } from 'vuex'

export default {
  computed: {
    ...mapState(['todos'])
  },
  methods: {
    ...mapActions(['getTodos'])
  }
}</code>
