播放从conf文件夹中读取路由的框架文件 [英] play framework reading file from conf folder with routing

问题描述

我有一个带有Play框架的Web应用程序.应用程序中使用的所有图像都保存在公用文件夹中，并可以通过conf/route文件中定义的路由进行访问.因此，构建后，我使用的所有图像都存在jar文件中.但是我的要求是，管理员将放置少量UI应该可以访问的图像.出于明显的原因，我可以要求他们将图像添加到jar中.

I have a web application with play framework. All images used in the application are kept in public folder and are accessed with the help of a routing defined in the conf/route file. So all the images I used are present in a jar file after build. But my requirement is that the admin will be placing few images that the UI should be able to access. For obvious reasons I can ask them to add images into the jar.

我的计划是请管理员将图像添加到conf文件夹内的文件夹中，然后使用路由从那里读取它(我相信这是可能的，因为当前有一个路由定义已从配置文件中读取json). /p>

My plan is to ask the admin to add images to a folder inside the conf folder and read it from there using routing (I believe its possible because currently there is a routing defined that's reading a json from the config file).

# Home page
GET     /                           controllers.Application.index
GET     /clientConfig               controllers.Application.clientConfiguration
GET     /testImg                    controllers.Application.testImg

# Map static resources from the /public folder to the /assets URL path
GET     /assets/*file                controllers.Assets.versioned(path="/public", file: Asset)

对于Play框架来说是全新的东西，我想不出一种方法来为此定义路由并从conf文件夹内的文件夹中读取图像.任何帮助都将受到高度赞赏.

Being totally new to Play framework I can't figure out a way to define routes for that and read images from a folder inside the conf folder . Any help is highly appreciated.

推荐答案

正如LiorH所说，通常不建议将conf文件夹公开.但是，如果这确实是您想要的，那么您可以尝试实现自己的控制器.

As LiorH said, it's usually not a good idea to expose conf folder to public. But if this is really what you want, then you can try to implement your own controller.

在您的route文件中:

GET /configuration       ConfController.loadConf(path)

在ConfController中:

def loadConf(path: String) = Action {
    Ok.sendFile(Play.getFile("conf$path"))
}
