ASP.NET Core + Vue.js 开发

Posted 2021-02-11 Kiralin

1、新建 项目文件夹 pro,在 VS CODE 打开终端，输入dotnet new mvc 命令，新建asp.net core项目。

2、在Startup.cs添加webpack的引用与配置

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.AspNetCore.SpaServices.Webpack;

namespace pro
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });


            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                ///////////////////////////////
                app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
                {
                    HotModuleReplacement = true
                });
                ///////////////////////////////////
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
                ///////////////////////////////////////////////////
                routes.MapSpaFallbackRoute(
                    name: "spa-fallback",
                    defaults: new { controller = "Home", action = "Index" });
                ///////////////////////////////////////////////////////
            });
        }
    }
}

3、在根目录下添加webpack.config.js，负责配置webpack如何将vue，js，css，scss等其他文件编译到输出文件中。

var path = require(‘path‘)
var webpack = require(‘webpack‘)
const bundleOutputDir = ‘./wwwroot/dist‘; ///////输出目录

module.exports = {
 context: __dirname,
  entry: { main: ‘./ClientApp/index.js‘ },  ////////////vue.js程序根目录
  module: {
    rules: [
      {
        test: /.css$/,
        use: [
          ‘vue-style-loader‘,
          ‘css-loader‘
        ],
      },
      {
        test: /.vue$/,
        loader: ‘vue-loader‘,
        options: {
          loaders: {
            ‘scss‘: [
              ‘vue-style-loader‘,
              ‘css-loader‘,
              ‘sass-loader‘
            ],
            ‘sass‘: [
              ‘vue-style-loader‘,
              ‘css-loader‘,
              ‘sass-loader?indentedSyntax‘
            ]
          }
        }
      },
      {
        test: /.js$/,
        loader: ‘babel-loader‘,
        exclude: /node_modules/
      },
      {
        test: /.(png|jpg|gif|svg)$/,
        loader: ‘file-loader‘,
        options: {
          name: ‘[name].[ext]?[hash]‘
        }
      }
    ]
  },
  resolve: {
    alias: {
      ‘vue$‘: ‘vue/dist/vue.esm.js‘
    },
    extensions: [‘*‘, ‘.js‘, ‘.vue‘, ‘.json‘]
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true
  },
  performance: {
    hints: false
  },output: {
    path: path.join(__dirname, bundleOutputDir),
    filename: ‘[name].js‘,
    publicPath: ‘dist/‘
},
  devtool: ‘#eval-source-map‘
}

if (process.env.NODE_ENV === ‘production‘) {
  module.exports.devtool = ‘#source-map‘
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      ‘process.env‘: {
        NODE_ENV: ‘"production"‘
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

4、在根目录下添加.babelrc ，用于解析ES6语法

{
    "presets": [
        ["env", { "modules": false }],
        "stage-3"
    ]
}

5、在根目录下添加package.json，配置npm包

{
  "name": "aspnetcore-vuejs",
  "private": true,
  "version": "0.0.0",
  "devDependencies": {
    "@types/webpack-env": "^1.13.5",
    "aspnet-webpack": "^2.0.3",
    "babel-plugin-transform-object-rest-spread": "^6.26.0",
    "css-loader": "^0.25.0",
    "event-source-polyfill": "^0.0.7",
    "extract-text-webpack-plugin": "^2.1.2",
    "file-loader": "^0.9.0",
    "isomorphic-fetch": "^2.2.1",
    "jquery": "^3.3.1",
    "node-sass": "^4.5.3",
    "sass-loader": "^6.0.6",
    "style-loader": "^0.13.1",
    "url-loader": "^0.5.7",
    "webpack": "^2.7.0",
    "webpack-hot-middleware": "^2.21.0"
  },
  "dependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-polyfill": "^6.26.0",
    "babel-preset-env": "^1.6.1",
    "babel-preset-stage-3": "^6.24.1",
    "vue": "^2.5.13",
    "vue-loader": "^14.0.3",
    "vue-router": "^3.0.1",
    "vue-template-compiler": "^2.5.13"
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not ie <= 8"
  ]
}

6、执行dotnet restore命令

7、执行npm install(可用cnpm淘宝镜像代替)

8、修改Index.cshtml视图

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>- asp.net core 2.1 - vue.js</title>
    <script src="~/dist/main.js" asp-append-version="true"></script>
</head>
<body>
    <div id=‘app‘>Loading...</div>
</body>
</html>

9、添加ClientApp文件夹并创建以下：

index.js

import Vue from ‘vue‘
import VueRouter from ‘vue-router‘  //导入路由插件的包
import App from ‘./App.vue‘  //导入根组件

Vue.config.productionTip = false
Vue.use(VueRouter) //安装路由模块

const routes = [
  { 
    path: ‘/‘, 
    component: App
  }
]

const router = new VueRouter({    //创建路由对象
  routes,
  mode: ‘history‘
})

new Vue({
  el: ‘#app‘,
  render: h => h(App),
  router //挂载路由对象到 VM 实例上
})

app.vue

<template>
    <div id="home">
        <h1>Hello World!</h1>
        <h1>I an what I an</h1>
    </div>
</template>

<script>
export default { }
</script>

<style lang="scss">

</style>

至此，.net core + vue.js 项目就搭建完成了。
