在vuejs / webpack中构建后,<img src=""/>正在生成不同的路径

我是Vuejs的新手。我正在一个项目中,我必须在Vue组件中显示图像。在我的组件中,我正在显示如下图像:

<img src="./../../images/back-arrow.png">

然后构建后不显示。当我检查我的代码时,它显示了不同的地址,如下所示:

<img src="/js/back-arrow.png?c4a414352d997e4618088074e1da917a">

我的文件夹结构是:

  • 资产
    • 组件
      • VueTemplate.vue //这是我显示图像的地方
    • 图片
      • back-arrow.png
    • js // npm运行构建位置

我不知道为什么它会改变,有人可以帮我吗? TIA

我的webpack配置:

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './admin/assets/main.js',
  output: {
    path: path.resolve(__dirname, 'admin/js'),
    publicPath: '/js/',
    filename: 'graphs-lite-admin.js'

          'css-loader'
        ],
      },
      {
        test: /\.scss$/,
        use: [

          'css-loader',
          'sass-loader'
        ],
      },
      {
        test: /\.sass$/,
        use: [
          'vue-style-loader',

        loader: 'vue-loader',
        options: {
          loaders: {
            // Since sass-loader (weirdly) has SCSS as its default parse mode, we map
            // the "scss" and "sass" values for the lang attribute to the right configs here.
            // other preprocessors should work out of the box, no loader config like this necessary.
            'scss': [
              'vue-style-loader',
              'css-loader',
              'sass-loader'
            ],
            'sass': [

            ]
          }
          // other vue-loader options go here
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },

        exclude: /node_modules/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]',
          outputPath: 'images/'
        }
      }
    ]
  },
  resolve: {
    alias: {

if (process.env.NODE_ENV === 'production') {

  module.exports.plugins = (module.exports.plugins || []).concat([

如果使用vue-cli 3.0创建了项目,则可以使用filenameHashing选项将其删除。

在项目根目录上创建class Category extends Component { constructor() { super(); this.state = { name: '', errors: {}, categories: [], loading: true, } this.handleInputChange = this.handleInputChange.bind(this); this.handleSubmit = this.handleSubmit.bind(this); } componentDidMount() { let self = this; axios.get('/categories') .then(function(response) { self.setState({ categories: response.data, loading: false, }); }).catch(err => { if (err.response.status === 401) { this.props.history.push('/'); } return err; }) } render() { if (this.state.loading) { return <div /> } return <ActualComponent /> } 文件,然后将其写入。

characters = [x for x in some_string]

查看此链接:https://cli.vuejs.org/config/#filenamehashing

或者,如果您使用的是webpack配置文件,请从输出中删除vue.config.js

module.exports = {
  filenameHashing: false
}

我找到了一个临时解决方案。问题出在webpack中。我不得不使用装载机。我使用了网址加载器。

 {
    test: /\.(png|jpg|gif|svg)$/,
    loader: 'url-loader',  //adding this line solved my problem
    options: {
      name: '[name].[ext]?[hash]'
    }
  }
