javascript - Webpack url 不正确

Question

我在 webpack 正确解析 URL 时遇到问题。当在我的本地 Node 服务器上运行时(因为它很方便)，它的工作方式就像一个魅力，但是当我将它上传到我的服务器时，一旦我将它放入子文件夹( http://hostname.com/folder )，如果我将它放在根目录中，它就会停止工作。

我通过 require break 在 JS 中加载的图像。它们位于我的项目根目录的“ Assets ”文件夹内。但它会在服务器的根目录中搜索。

Webpack 配置:

var webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var path = require('path');

var config = require('./_config'); //paths config..

module.exports = {
    entry: [
        config.build('js', 'src'), //JavaScript entry point
        config.build('css', 'src'), //CSS entry point
    output: {
        path: config.js.dest.path,
        filename: config.js.dest.file //JavaScript end point
    }, //quickest, webpack -d -p for production
    devtool: 'eval',
    module: {
        //test: which filetype?,
        //exclude: which folders to exclude
        loaders: [{
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'babel',
            query: {
              babelrc: path.join(__dirname, '.babelrc')
            }
        }, {
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'eslint'
        }, {
            test: /\.scss$/,
            loader: ExtractTextPlugin.extract('css!postcss!sass?outputStyle=expanded')
        }, {
            test: /\.json$/,
            loader: 'file?hash=sha512&digest=hex&name=../assets/[hash].[ext]'
        }, {
            test: /\.(jpe?g|png|gif|svg)$/i,
            loaders: [
                'file?hash=sha512&digest=hex&name=../assets/[hash].[ext]',
                'image-webpack?{progressive:true, optimizationLevel: 7, interlaced: false, pngquant:{quality: "65-90", speed: 4}}'
            ]
        }]
    }, postcss: function(){
        return [
            require('postcss-will-change'),
            require('postcss-cssnext')({
                browsers: ['IE >= 10', 'last 2 version'],
                features: {
                    autoprefixer: {
                        cascase: false
                    }
                }
            })
        ]
    }, //webpack plugins
    plugins: [
        new webpack.optimize.DedupePlugin(),
        //extract CSS into seperate file
        new ExtractTextPlugin(
            config.build('css', 'dest')
        )
    ], eslint: {
        configFile: path.join(__dirname, '.eslintrc'),
        ignorePath: path.join(__dirname, '.eslintignore')
    }, resolve: {
        extensions: ['', '.json', '.js', '.css'],
        fallback: path.join(__dirname, 'node_modules')
    }, resolveLoader: {
        fallback: path.join(__dirname, 'node_modules')
    }
};

提前致谢!

Answer 1

设置publicPath指向您的 Assets 目录。示例:

output: {
  path: config.js.dest.path,
  filename: config.js.dest.file,
  publicPath: 'assets'
}

此外，您需要像这样调整加载器定义:

loader: 'file?hash=sha512&digest=hex&name=./assets/[hash].[ext]'

完成这些调整后，您的应用程序可以正常运行，没有任何错误。
