Question

我希望Play将GZipped JS和CSS发送到浏览器。在Build.scala中，我添加了

 val gzipAssets = TaskKey[Seq[File]]("gzip-assets", "GZIP all assets")
 lazy val gzipAssetsSetting = gzipAssets <<= gzipAssetsTask
 lazy val gzipAssetsTask = (gzippableAssets, streams) map {
  case (finder: PathFinder, s: TaskStreams) => {
    finder.get.map { file =>
      val gzTarget = new File(file.getAbsolutePath + ".gz")
      IO.gzip(file, gzTarget)
      s.log.info("Compressed " + file.getAbsolutePath + " " + file.length / 1000 + " k     => " + gzTarget.getName + " " + gzTarget.length / 1000 + " k")
      gzTarget
    }
  }
}

val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA).settings(
    // Twitter Bootstrap v2.0.1 compilation (https://plus.google.com/u/0/108788785914419775677/posts/QgyUF9cXPkv)
    lessEntryPoints <<= (sourceDirectory in Compile)(base => ((base / "assets" / "stylesheets" / "twitterbootstrap" / "styles.less"))),

    // set up gzip of assets
    gzippableAssets <<= (resourceManaged in (ThisProject))(dir => ((dir ** "*.js") +++ (dir ** "*.css"))),
    gzipAssetsSetting,
    playPackageEverything <<= playPackageEverything dependsOn gzipAssets


).settings( ...

当我在dist时生成目标中的文件：

[info] Compressed /Users/wimha/Documents/**/target/scala-2.9.1/resource_managed/main/public/stylesheets/twitterbootstrap/styles.min.css 183 k =＆gt; styles.min.css.gz 27 k

但是，在prod中，该文件不可用：

无法加载资源：服务器响应状态为404（未找到）http://ec2-54-228-70-193.eu-west- 1.compute.amazonaws.com/assets/stylesheets/twitterbootstrap/styles.min.css.gz

我有两个问题：

为什么文件不可用？
你有更好的解决方案吗？也许有一个模块？除了Play 1.x之外，我没有找到一些有趣的东西，但它只是播放我想将我的资产合并到一个文件中。

我为同样的问题寻找解决方案的时间很少。

试试这个：http://play.lighthouseapp.com/projects/82401/tickets/841-gzip-assets。无论您运行.gz还是play dist，它都会打包play stage个文件。

鉴于Play已经足够聪明，可以在a 相应的.gz文件存在，gzip资产何时才有意义做'舞台'或'分开'。一些反向代理可以gzip资源，但是这要么效率较低（如果为每个请求完成）或更多复杂（如果资源被缓存，最终可能会过时）。

这是使用Build.scala的半生不熟的解决方案：

val gzippableAssets = SettingKey[PathFinder]("gzippable-assets", "Defines the files to gzip")
val gzipAssets = TaskKey[Seq[File]]("gzip-assets", "gzip all assets")
lazy val gzipAssetsSetting = gzipAssets <<= gzipAssetsTask dependsOn (copyResources in Compile)
lazy val gzipAssetsTask = (gzippableAssets, streams) map {
  case (finder: PathFinder, s: TaskStreams) => {
    var count = 0
    var files = finder.get.map { file =>
      val gzTarget = new File(file.getAbsolutePath + ".gz")
      IO.gzip(file, gzTarget)
      count += 1;
      gzTarget
    }
    s.log.info("Compressed " + count + " asset(s)")
    files
  }
}

val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA).settings(
    ...
    gzippableAssets <<= (classDirectory in Compile)(dir => (dir ** ("*.js" || "*.css" || "*.html"))),
    gzipAssetsSetting,
    playPackageEverything <<= playPackageEverything dependsOn gzipAssets
)
