Gulp自动添加版本号

转载自：http://www.cnblogs.com/givebest/

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nodemodules\gulp-rev\nodemodules\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"
