playframework 2.0 - Play Framework - Authentication for Assets -


I'm developing an app where I want to limit access to properties. I have created an additional folder 

  secret /

which holds the data

and the controller media 

  / media / secret / * file controller. Media. File (File)  
  Expands Public Class Media Controller {@Profile the public results file (string file) {string path = / home / afu / secret path / filef = new file (Path, file); If (! F.exists ()) {return notound (); } The return is OK (f, true); }  
 
 This type of work, the only problem is that there is no etag or cache control to check the assets. Scala implementation () Everything has already been developed here. My question is 
 
     
  1.  Should I write additional code to implement Etag and CashControl? if so, how? I can not read Scala 
    2.  
  2.  If there is any way to use the property class, how should it work? Returning action @ will not trigger @ so that I can validate whether it is ok or not. 
    3.

You can use the action structure, see:

(1) New verb 

  def only unauthenticated [A] (Action: Action [A]) = Action Async (Action Pursuit) {Request = & gt; Request.session.get ("username") match {case something (username) = & gt; User.findByU Name (Username) Match {Case Something (User) = & gt; Action (request) case _ = & gt; Future. Successful (forbidden (views.html.defaultpages.unauthorized.render ()))} Case _ = & gt; Future. Successful redirects (request. Path.path))}}

(2) controller action 

  def privateAsset (file: string ) = Only authorized {assets} .et (s "/ private", file)}

(3) root 

  received / private / * file controller. Application: PrivateAsset (File)

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
