如何在ActionScript中使用base64編碼解壓縮文件？

我在這裏有一個問題，解壓縮我在combobox.i中的.zip文件，選擇1 .zip文件，然後選擇特定的.zip文件按鈕應解壓縮並將內容放入另一個組合框中。有人可以幫我在這裏？如何在ActionScript中使用base64編碼解壓縮文件？

這裏是一個代碼：

// ActionScript file 
    import flash.display.*; 
    import flash.events.*; 
    import flash.utils.ByteArray; 
    import com.Base64; 
    import mx.controls.Alert; 

    [Bindable] private var sfile:FileReference; 
    [Bindable] private var zipdataProvdr:ArrayCollection = new ArrayCollection([{label:  "test", file: "test"},{label: "elm34001", file: "elm34001"}, {label: "elm34003", file: "elm34003"}, {label: "elm34005", file: "elm34005"}, {label: "elm34009", file: "elm34009"},{label: "elm34011", file: "elm34011"}, {label: "elm34013", file: "elm34013"}]); 
     //private var zip:FZip; 
     //private var flag:Boolean; 


     private function init(event:Event):void 
     { 
     var file:ByteArray = new ByteArray(); 
     file = "test.zip"; 
     var encode:String = Base64.encodeByteArray(file); 
     Alert.show("Encoded file is " + encode); 
     for (var i:int = 0; i < zipdataProvdr.length; i++) 
     { 
     file = zipdataProvdr[i]; 
     Alert.show("file is " + file); 
     } 
     //var encoded:String = Base64.encodeByteArray(file); 
     //Alert.show("encoded file is " + encoded.toString()); 


     }

你能展示一些你目前在做什麼的代碼嗎？你卡在哪裏？ –

上面是代碼，我不能將一個zip文件分配給bytearray變量？ – kanak

我不知道你能。沒有必要重新發明輪子，嘗試使用這樣一個zip庫而不是：

可以請你發表一個代碼嗎？ – kanak

號您是否點擊鏈接？那裏有代碼。 –

感謝您的幫助公民康恩！ – kanak

我用Nochump lib解壓縮文件。以下是代碼：
