如何使用Adobe AIR 2.0加密数据库SQLite的 [英] How to encrypt database SQLite using Adobe AIR 2.0

问题描述

我只想问如何使用Adobe AIR 2.0加密数据库。我发现C $ CS约$使用Adobe AIR 1.5。这里的C $ CS $：

i just wanna ask how to encrypt database using adobe air 2.0. I found some codes using Adobe air 1.5. here the codes:

// Include AIRAliases.js to use air.* shortcuts
var conn = new air.SQLConnection(); 
conn.addEventListener(air.SQLEvent.OPEN, openHandler); 
conn.addEventListener(air.SQLErrorEvent.ERROR, errorHandler); 
var dbFile = air.File.applicationStorageDirectory.resolvePath("DBSample.sqlite"); 

var encryptionKey = new air.ByteArray(); 
encryptionKey.writeUTFBytes("Some16ByteString"); // This technique is not secure! 

conn.openAsync(dbFile, air.SQLMode.CREATE, null, false, 1024, encryptionKey); 

function openHandler(event) 
{ 
    air.trace("the database opened successfully"); 
} 

function errorHandler(event) 
{ 
    if (event.error.errorID == 3138) 
    { 
        air.trace("Incorrect encryption key"); 
    } 
    else 
    { 
        air.trace("Error message:", event.error.message); 
        air.trace("Details:", event.error.details); 
    } 
}

这是行不通的。它只是显示错误： air.SQLMode不是一个对象

任何人都可以修复它​​？谢谢

anybody can fix it? Thanks

推荐答案

你看到空气中的原因。*别名，是因为这个例子的目的是在JavaScript中使用。如果你使用ActionScript，你将需要删除的空气。*别名，只导入类来代替。

The reason you're seeing the air.* aliases is because the example is intended to be used in JavaScript. If you're using ActionScript you'll need to remove the air.* aliases and just import the classes instead.

有关JavaScript的，因为没有进口的说法，AIR团队创建的所有AIR类创建别名文件的AIRAlias​​es.js，这样就不必每次都使用完全限定类名要使用的类。

For JavaScript, since there is no "import" statement, the AIR team created a file airaliases.js that creates aliases for all the AIR classes, so that you don't have to use the fully-qualified class name every time you want to use the class.
