在 URL 中嵌入 ETag [英] Embed ETag in URL

问题描述

关于 Play 中资产指纹识别的问题.

A question about asset fingerprinting in Play.

如何让 Play 在不使用第三方插件的情况下在 URL 中嵌入 ETag?

How to ask Play to embed ETags in URLs without using a third-party plugin?

例如，如果 /css/resource.css 有 1234 的 ETag，那么它会变成 /css/responsive-1234.css.

E.g., if /css/resource.css had the ETag of 1234, then it would become /css/responsive-1234.css.

推荐答案

将有出"路由和入"反向路由.首先是出"路由:

There'll be the "out" routing and the "in" reverse routing. Firstly the "out" routing:

  package controllers

  import play.api.mvc._

  object Resources extends Controller {

    def fingerprintedUrl(path: String): String = {
      // calculates ETag and add to URL path
      val pathWithEtag = addEtagToPath(path)
      pathWithEtag
    }
  }

然后在模板中使用以下示例:

Then in templates use the following for example:

 <script src="@Resources.fingerprintedUrl("js/toolkit.js")"></script>

现在是反向路由，在同一个控制器中添加以下内容:

Now the reverse routing, add the following to the same controller:

  def at(path: String): Action = {
    val pathWithoutEtag = removeEtagFromPath(path)
    Assets.at("/public", pathWithoutEtag)
  }

然后在routes:

  GET  /resources/*file  controllers.Resources.at(file)
