我正在使用webpack来管理reactjs项目。我想通过 webpack 在 javascript 中加载图像file-loader。下面是webpack.config.js：

const webpack = require('webpack');
const path = require('path');
const NpmInstallPlugin = require('npm-install-webpack-plugin');

const PATHS = {
    react: path.join(__dirname, 'node_modules/react/dist/react.min.js'),
    app: path.join(__dirname, 'src'),
    build: path.join(__dirname, './dist')
};

module.exports = {
    entry: {
        jsx: './app/index.jsx',
    },
    output: {
        path: PATHS.build,
        filename: 'app.bundle.js',
    },
    watch: true,
    devtool: 'eval-source-map',
    relativeUrls: true,
    resolve: {
        extensions: ['', '.js', '.jsx', '.css', '.less'],
        modulesDirectories: ['node_modules'],
        alias: {
            normalize_css: __dirname + '/node_modules/normalize.css/normalize.css',
        }
    },
    module: {
        preLoaders: [

            {
                test: /\.js$/,
                loader: "source-map-loader"
            },
        ],
        loaders: [

            {
                test: /\.html$/,
                loader: 'file?name=[name].[ext]',
            },
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loader: 'babel-loader?presets=es2015',
            },
            {test: /\.css$/, loader: 'style-loader!css-loader'},
            {test: /\.(jpe?g|png|gif|svg)$/i, loader: "file-loader?name=/public/icons/[name].[ext]"},
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loaders: ['babel-loader?presets=es2015']
            }
        ]
    },
    plugins: [
        new webpack.optimize.UglifyJsPlugin({
            compress: {
                warnings: false,
            },
            output: {
                comments: false,
            },
        }),
        new NpmInstallPlugin({
            save: true // --save
        }),
        new webpack.DefinePlugin({
            "process.env": {
                NODE_ENV: JSON.stringify("production")
            }
        }),
    ],
    devServer: {
        colors: true,
        contentBase: __dirname,
        historyApiFallback: true,
        hot: true,
        inline: true,
        port: 9091,
        progress: true,
        stats: {
            cached: false
        }
    }
}

我使用这一行来加载图像文件并将它们复制到 dist/public/icons 目录并保持相同的文件名。

{test: /\.(jpe?g|png|gif|svg)$/i, loader: "file-loader?name=/public/icons/[name].[ext]"}

但是我在使用它时有两个问题。当我运行webpack命令时，图像文件已按预期复制到dist/public/icons/目录。然而，它也被复制到 dist 目录，文件名为“df55075baa16f3827a57549950901e90.png”。

下面是我的项目结构：

另一个问题是我使用下面的代码来导入这个图像文件，但它没有显示在浏览器上。如果我在 img 标签上使用 url 'public/icons/imageview_item_normal.png'，它工作正常。如何使用从图像文件中导入的对象？

import React, {Component} from 'react';
import {render} from 'react-dom';
import img from 'file!../../public/icons/imageview_item_normal.png'

export default class MainComponent extends Component {

  render() {
    return (
      <div style={styles.container}>
        download
        <img src={img}/>
      </div>
    )
  }

}

const styles = {
  container: {
    width: '100%',
    height: '100%',
  }
}
