图像未在浏览器中加载 react、webpack 和 express

Question

我正在 react 中构建一个网站。在我实施快递之前，它工作正常。实现 express 后，我无法加载某些资源，尤其是浏览器中的图像。图像路径正确，但图像未显示在浏览器中。

webpack.config.js是：

var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
devtool: 'eval-source-map',
entry: [
'webpack-hot-middleware/client?reload=true',
path.join(__dirname, 'app/index.js')
],
output: {
path: path.join(__dirname, '/dist/'),
filename: '[name].js',
publicPath: '/'
},
plugins: [
new ExtractTextPlugin('/bundle.css', { allChunks: true }),
new HtmlWebpackPlugin({
template: 'app/index.html',
inject: 'body',
filename: 'index.html'
}),
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin(),
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production')
})
],
resolve: {
extensions: ['', '.scss', '.css', '.js', '.json'],
modulesDirectories: [
'node_modules',
path.resolve(__dirname, './node_modules')
]
},
module: {
loaders: [{
test: /.jsx?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
"presets": ["react", "es2015", "stage-0", "react-hmre"]
}
}, {
test: /.json?$/,
loader: 'json'
}, {
test: /.scss$/,
loader: ExtractTextPlugin.extract('style', 'css?sourceMap&modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!postcss!sass')
}, {
test: /.css$/,
loader: 'style-loader!css-loader'
},{
test: /.(png|jpg|jpeg|gif|svg|woff|woff2)$/,
loader: "url-loader?limit=10000"
},{
test: /.less$/, loader: "style-loader!css-loader!less-loader"
},{
test: /.(ttf|eot|svg|woff|woff2)(?v=[0-9].[0-9].[0-9])?$/, 
loader: "file-loader"
}]
}
};

server.js文件内容如下：

const path = require("path");  
const express = require("express");  
const webpack = require("webpack");  
const webpackDevMiddleware = require("webpack-dev-middleware");  
const webpackHotMiddleware = require("webpack-hot-middleware");  
const config = require("./webpack.config.js");
const app           = express(),  
DIST_DIR      = path.join(__dirname, "dist"),
HTML_FILE     = path.join(DIST_DIR, "index.html"),
isDevelopment = process.env.NODE_ENV !== "production",
DEFAULT_PORT  = 3000,
compiler      = webpack(config);
app.set("port", process.env.PORT || DEFAULT_PORT);
if (isDevelopment) {  
app.use(webpackDevMiddleware(compiler, {
publicPath: config.output.publicPath
}));
app.use(webpackHotMiddleware(compiler));
app.get("*", (req, res, next) => {
compiler.outputFileSystem.readFile(HTML_FILE, (err, result) => {
if (err) {
return next(err);
}
res.set('content-type', 'text/html');
res.send(result);
res.end();
});
});
}
else {  
app.use(express.static(DIST_DIR));
app.get("*", (req, res) => res.sendFile(HTML_FILE));
}
app.listen(app.get("port"));

package.json如下：

"main": "server.js",
"script": {
"start": "babel-node server-es6.js",
"build:server": "babel server-es6.js --out-file server.js",
"build:client": "webpack -p --config webpack.config.js --progress"
},

网站正在加载，但某些 CSS 未加载。控制台抛出错误：

获取 http://bundle.css/网：：ERR_NAME_NOT_RESOLVED

图像路径正确显示为http://localhost:3000/img/img1.png但未显示在浏览器中。我认为问题出在网络包公共路径上。

当我使用<img src={require('/images/image-name.png')} />时，它工作正常。但我不想这样做，因为它是非常繁重的代码库，而且我认为这不是一个好的解决方案。

我已经从webpack-express-boilerplate获得了帮助。

在chrome网络工具中，图像类型为text/html。

如果文件路径是静态的，则可以导入文件一次，然后将其作为 src 提供

import image from '/path/to/images/image-name.png';
...
<img src={image} />
