REQUEST_URI in Flex

Mar. 7, 2007 9 Comments Posted under: ActionScript, Flex

I recently found it very hard to discover the current URL in the browser from within my Flex aplication. I needed it so I knew which SOAP server to connect to depending on if the instance of the application was on dev, staging or live.

So in order to get the current URI I used this:


import flash.external.*; // Put this in the package

var currentUri:String = ExternalInterface.call("window.location.href.toString");

Then you can go about hacking it with string functions or regexp as you wish!

    would this work in flash? , when i try in flash8 AS2 i cant import the package without errors
    but: 

    
var currentUri:String = ExternalInterface.call("document.location.href.toString");

    gives me an error

    
**Error** Scene=Scene 1, layer=Layer 3, frame=1:Line 6: Type mismatch in assignment statement: found Object where String is required.
     var currentUri:String = ExternalInterface.call("document.location.href.toString");

    if i change it to 

    
var currentUri:String then it returns an empty object.

    :/

    damn, i meant:
    when i try in flash8 AS2 i _CAN_ import the package without errors

    and i also meant to write
    “if i change it to var currentUri:Object”

    this is going well =/ sorry for meesing up.

    Try tracing:

    document.location.href

    and see what it returns. You shouldn’t be getting that error as you are saying .toString()

    I have never developed in flash though so can’t really help. Sorry

    Of course, this only works if “allowScriptAccess” is not set to “never”. Which is where I find myself… :(

    Where would it be set to never?

    I happen to be addressing this same problem. I forget where I saw this trick, but this works for me (adapted for your variable names)

    var currentUri:String = String( ExternalInterface.call(” function(){ return document.location.href.toString();}”));

    So, the idea is that your call statement calls a function defined on the fly and returns the value you are interested in.

    I have been on this referer issue for ages!!

    the :

    var url:String = String( ExternalInterface.call(” function(){ return document.location.href.toString();}”));

    worked a charm!! Im using as2 and flash 8..

    as3 is almost the same which is why it was killing me.
