无法使用dotnet angular webpack加载图像

我关注了"Building Single Page Applications on ASP.NET Core with JavaScriptServices"博文。从那时起我就能够在 ASp.NET Core 上创建一个新的 Angular2 模板。该应用程序运行良好并使用webpack(不知道这是可能的)。

dotnet new angular    
dotnet restore    
npm install    
dotnet run

我想知道如何将img添加到角度模板并为其提供已知的src网址 - 并且它可以正常工作。对于我的生活,我无法弄清楚这一点。这是webpack.config.js

const path = require('path');
const webpack = require('webpack');
const merge = require('webpack-merge');
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;

module.exports = (env) => {
    // Configuration in common to both client-side and server-side bundles
    const isDevBuild = !(env && env.prod);
    const sharedConfig = {
        stats: { modules: false },
        context: __dirname,
        resolve: { extensions: [ '.js', '.ts' ] },
        output: {
            filename: '[name].js',
            publicPath: '/dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
        },
        module: {
            rules: [
                { test: /\.ts$/, include: /ClientApp/, use: ['awesome-typescript-loader?silent=true', 'angular2-template-loader'] },
                { test: /\.html$/, use: 'html-loader?minimize=false' },
                { test: /\.css$/, use: ['to-string-loader', 'css-loader'] },
                { test: /\.(png|jpg|jpeg|gif|svg)$/, use: 'url-loader?limit=25000' }
            ]
        },
        plugins: [new CheckerPlugin()]
    };

    // Configuration for client-side bundle suitable for running in browsers
    const clientBundleOutputDir = './wwwroot/dist';
    const clientBundleConfig = merge(sharedConfig, {
        entry: { 'main-client': './ClientApp/boot-client.ts' },
        output: { path: path.join(__dirname, clientBundleOutputDir) },
        plugins: [
            new webpack.DllReferencePlugin({
                context: __dirname,
                manifest: require('./wwwroot/dist/vendor-manifest.json')
            })
        ].concat(isDevBuild ? [
            // Plugins that apply in development builds only
            new webpack.SourceMapDevToolPlugin({
                filename: '[file].map', // Remove this line if you prefer inline source maps
                moduleFilenameTemplate: path.relative(clientBundleOutputDir, '[resourcePath]') // Point sourcemap entries to the original file locations on disk
            })
        ] : [
            // Plugins that apply in production builds only
            new webpack.optimize.UglifyJsPlugin()
        ])
    });

    // Configuration for server-side (prerendering) bundle suitable for running in Node
    const serverBundleConfig = merge(sharedConfig, {
        resolve: { mainFields: ['main'] },
        entry: { 'main-server': './ClientApp/boot-server.ts' },
        plugins: [
            new webpack.DllReferencePlugin({
                context: __dirname,
                manifest: require('./ClientApp/dist/vendor-manifest.json'),
                sourceType: 'commonjs2',
                name: './vendor'
            })
        ],
        output: {
            libraryTarget: 'commonjs',
            path: path.join(__dirname, './ClientApp/dist')
        },
        target: 'node',
        devtool: 'inline-source-map'
    });

    return [clientBundleConfig, serverBundleConfig];
};

组件

import { Component } from '@angular/core'

@Component({
    selector: 'example',
    template: `<img src='dist/myimg.png' />`
})
export class ExampleComponent { }

更新

我发现这个SO Q&A有助于澄清一些事情。现在的问题是我需要动态获取图像。

Steve回答了有关 Angular2 + ASP.NET Core 模板的问题。我想知道如何动态地执行此操作,而不是静态地执行此操作。我想使用 Angular2 绑定并从服务器获取图像名称,然后将其绑定到img src。任何有关如何做到这一点的想法将不胜感激。似乎webpack需要提前知道它才能捆绑

将图像放入wwwroot / dist然后......

<?php if (have_posts()) : ?>
<ul class="content">

    <?php
    $counter = 0;
    while (have_posts()) : the_post();
        $p = new Wpi_Article_Item(array(
            'show_snippet' => true,
            'show_category' => true,
            'show_comment_number' => true,
            'show_date' => true,
            'category' => 1,
            'snippet_length' => 200
        ));

        echo '<li class="item item-' . $counter . ' item-' . (($counter == 0) ? 'first active' : 'other') . ' item-' . (($counter % 2) ? 'odd' : 'even') . (($counter % 3) ? '' : ' item-triple') . '"><div class="inner">';

        echo $p->review() . $p->thumbnail('natural_full') . $p->cates() . $p->title() . $p->meta() . $p->snippet(true);

        echo '<div class="clear"></div></div></li>';
        $counter++;
    endwhile; /* end have_posts */

    ?>
