  • send a get request using vue-resource. You can see the requested data in the browser network, but the following code performs a failed callback

  •  you can see the obtained data, but the callback that failed is executed, outputting "fail"

then solve the cross-domain problem. I'll add a proxyTable function for you later according to your webpack-simple configuration.

webpack.config.js 
var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader'
        ],
      },      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
          }
          // other vue-loader options go here
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['*', '.js', '.vue', '.json']
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true,
    // --------------------
    proxy: {
      '/api':{
        target: 'http://localhost:7001',
        pathRewrite: {
          '/api': ''
        }
      }
    }
    //----------------------------------
  },
  performance: {
    hints: false
  },
  devtool: '-sharpeval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '-sharpsource-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

I generated it directly with the scaffolding you mentioned, and I added proxy directly on this basis. Is there any doubt?

console is not very clear. Are you cross-domain?

this is not a cross-domain problem, but how the url of your get is cached. The returned status code is 304.
it is estimated that vue-resource will only let 200 go success

.
