如何修復 vue 腳本中的“eslint(no-unused-vars)”

Question

我正在嘗試在 Vuejs 應用程序中運行服務器，但我遇到了 eslint 消息的問題，感謝您幫助修復它們

這是我的 Json 文件：

 {
   "name": "blog-frontend",
   "version": "0.1.0",
   "private": true,
   "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
 },
  "dependencies": {
   "axios": "^0.19.0",
   "core-js": "^3.3.2",
   "vue": "^2.6.10",
   "vue-router": "^3.0.6"
 },
  "devDependencies": {
   "@vue/cli-plugin-babel": "^4.0.0",
   "@vue/cli-plugin-eslint": "^4.0.0",
   "@vue/cli-plugin-router": "^4.0.0",
   "@vue/cli-service": "^4.0.0",
   "babel-eslint": "^10.0.1",
   "eslint": "^5.16.0",
   "eslint-plugin-vue": "^5.0.0",
   "vue-template-compiler": "^2.6.10"
 }
}

這是控制台上的消息：

  61 |         window.location.reload();

主頁.vue

<script>
 // @ is an alias to /src
 import {server} from "@/utils/helper";
 import axios from "axios";

export default {
 data() {
  return {
   posts: []
 };
},
created() {
 this.fetchPosts();
},
methosd: {
 fetchPosts() {
  axios
    .get('${server.baseURL}/blog/posts')
    .then(data => (this.posts = data.data));
},
deletePost(id) {
  axios.delete('${sever.baseURL}/blog/delete?postID=${id}').then(data => {
    console.log(data);
    window.location.reload();
   });
  }
 }
};
</script>

助手.js

export const server = {
 baseURL: 'http:localhost:3000'
}

main.js

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

Vue.config.productionTip = false

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

我希望有足夠的信息，您可以幫助我修復它們

使用字符串模板正確構建您的 url，如下所示；

axios.delete(`${server.baseURL}/blog/delete?postID=${id}`).then(data => {

然后將使用server和id並修復錯誤。
