如何在 vue 脚本中修复"eslint(no-unused-vars)"

Question

我正在尝试在 Vuejs 应用程序中运行服务器，但我在 eslint 消息方面遇到问题，感谢您帮助修复它们

这是我的 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"
}
}

这是控制台上的消息：

<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'
}

主.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

使用字符串模板正确构建您的 url，如下所示;

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

然后server和id将被使用，错误将被修复。
