推荐使用gulp-rev + gulp-rev-collector是比较方便的方法，结果如下:
"/css/style.css" => "/dist/css/style-1d87bebe.css"
"/js/script1.js" => "/dist/script1-61e0be79.js"
"cdn/image.gif" => "//cdn8.example.dot/img/image-35c3af8134.gif"
但是由于公司发布系统限制，如果用上面方法实现，每次更新都会积压过多过期无用的文件，我们预期效果是:
"/css/style.css" => "/dist/css/style.css?v=1d87bebe"
"/js/script1.js" => "/dist/script1.js?v=61e0be79"
"cdn/image.gif" => "//cdn8.example.dot/img/image.gif?v=35c3af8134"
怎么破?改上面两个Gulp插件是最高效的方法了。
1.安装Gulp
npm install --save-dev gulp
2.分别安装gulp-rev、gulp-rev-collerctor
npm install --save-dev gulp-rev
npm install --save-dev gulp-rev-collector
3.打开node_modules\gulp-rev\index.js
第133行 manifest[originalFile] = revisionedFile;
更新为: manifest[originalFile] = originalFile + '?v=' + file.revHash;
4.打开node_modules\gulp-rev\node_modules\rev-path\index.js
10行 return filename + '-' + hash + ext;
更新为: return filename + ext;
5.打开node_modules\gulp-rev-collector\index.js
31行 if ( path.basename(json[key]).replace(new RegExp( opts.revSuffix ), '' ) !== path.basename(key) ) {
更新为: if ( path.basename(json[key]).split('?')[0] !== path.basename(key) ) {
6.配置gulpfile.js, 可参考下面gulpfile.js代码
7.结果达到预期，如下：
Css
background: url('../img/one.jpg?v=28bd4f6d18');
src: url('/fonts/icomoon.eot?v=921bbb6f59');
Html
href="css/main.css?v=885e0e1815"
src="js/main.js?v=10ba7be289"
src="img/one.jpg?v=28bd4f6d18"
