【问题描述】：

我正在尝试在 Vuejs 应用程序中运行服务器，但我遇到了 eslint 消息的问题，感谢您帮助修复它们

这是我的 Json 文件：

   "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"

这是控制台上的消息：

</script>

helper.js

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

ma​​in.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')

我希望有足够的信息，您可以帮助我修复它们

【问题讨论】：

methosd 应该是 methods 而在 deletePost 中，你有 sever 而不是 server

另外，您在template literals 中使用单引号，但它们应该是反引号，即`$server.baseURL/blog/posts`

【参考方案1】：

使用字符串模板正确构建您的网址，如下所示；

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

然后将使用server 和id 并修复错误。
