For comparison, the files introduced this time are only added to the loaders

            {
                test: /\.(png|gif|jpg|jpeg|bmp|svg)/,
                use:[
                    {
                        loader: "url-loader",
	                    options: {
							limit: 8192,
                        	name: path.posix.join('static', './css_img/[hash:8].[name].[ext]')
						}
                    }
                ]
            }

 path.posix.join('static', './css_img/[hash:8].[name].[ext]')，

The content in brackets: static: is the main directory of the generated file, and the second value is the location of the generated file (below the output directory)

Directory Structure

Create a new static directory under the app directory, then build css_img, and put pictures under it

style.less

@f:white;
p{
    color: red;
}
p{
    width: 100%;
    height: 100px;
    background: url(../static/css_img/32132131.jpg) no-repeat center center;
    background-size: 100%; 
    a{
        color: @f;
    }
}

The structure of the output file

As you can see, the written files are generated in the _build directory

main.css

p {
  color: red;
}
p {
  width: 100%;
  height: 100px;
  background: url(../../_build/static/css_img/183f148e.32132131.jpg) no-repeat center center;
  background-size: 100%;
}
p a {
  color: white;
}
