How to achieve real-time updates of music classification lists through Vue and NetEase Cloud API

In modern society, music has become an indispensable part of our lives. How to implement real-time updates of music classification lists through Vue and NetEase Cloud API is a common requirement. This article will explain in detail how to use Vue and NetEase Cloud API to implement this function.

First of all, we need to understand the basic concepts of Vue and NetEase Cloud API. Vue is a progressive JavaScript framework for building user interfaces, while NetEase Cloud API is a set of interfaces provided by NetEase Cloud Music, which can be used to obtain information such as music classification lists.

Next, we need to build a Vue development environment. First, we need to install Node.js and npm. Then, install Vue scaffolding via npm. Execute the following command in the command line:

npm install -g @vue/cli

After the installation is complete, you can use the following command to create a new Vue project:

vue create music-app

Then enter the project directory and start the development server:

cd music-app
npm run serve

Next, we need to create a music category list component. Create a new folder components in the src directory and add a new file MusicCategoryList.vue. In this file, we can implement real-time updates of the music classification list.

<template>
  <div class="music-category-list">
    <ul>
      <li v-for="category in categories" :key="category.id">{{ category.name }}</li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      categories: []
    };
  },
  mounted() {
    this.fetchCategories();
  },
  methods: {
    fetchCategories() {
      // 使用网易云API获取音乐分类列表
      fetch('https://netease-api.music.glaciergears.com/playlist/categories')
        .then(response => response.json())
        .then(data => {
          this.categories = data.categories;
        });
    }
  }
};
</script>

<style scoped>
.music-category-list {
  /* 样式 */
}
</style>

In the above code, we first bind the categories array to the list in the template through data binding. Then, in the mounted method of the component, we use the fetch function to obtain the list of music categories, and then store the returned data into the categories array. In this way, when the component is rendered to the page, the music category list will be updated in real time.

Next, we need to add the MusicCategoryList component to the App.vue component. Modify the src/App.vue file as follows:

<template>
  <div id="app">
    <MusicCategoryList />
  </div>
</template>

<script>
import MusicCategoryList from './components/MusicCategoryList.vue';

export default {
  components: {
    MusicCategoryList
  }
};
</script>

<style>
/* 样式 */
</style>

Finally, we need to introduce the App.vue component into the main.js file and mount it on the page. Modify the src/main.js file as follows:

import Vue from 'vue';
import App from './App.vue';

Vue.config.productionTip = false;

new Vue({
  render: h => h(App)
}).$mount('#app');

At this point, we have completed the real-time update of the music classification list through Vue and NetEase Cloud API. Restart the development server and visit http://localhost:8080 in the browser, and you can see the real-time update effect of the music category list.

To sum up, it is a relatively simple task to implement real-time updates of music classification lists through Vue and NetEase Cloud API. We only need to create a music category list component, use the fetch function in the mounted method of the component to obtain the data of the music category list, and store it in the data attribute of the component for binding. In this way, when the component is rendered to the page, the list of music categories will be automatically updated. I hope this article can be helpful to everyone.
