使用Flash / Flex发布到Twitter

Question

I am trying to post a "tweet" to my twitter using Flex (using the Flex 3.5 SDK and Flex Builder 4 if that makes any difference). On an mxml file I've created a button simply to make it easy to call an AS3 function, and in the function, I'm making a URL request. Obviously I'm doing something wrong, because my tweet ain't posting. I got these variables in the curl request provided by Twitter themselves, which actually worked. My guess is that I'm formatting something incorrectly, but I don't know what that is....Thank you very much for any help you might provide. Here is the code I'm using: EDIT: I would like to clarify that I already have the appropriate authorization keys and such (as I made a Coldfusion script to handle that). I do not need help with authorization, just posting.

var postTO:URLRequest=new URLRequest("https://api.twitter.com/1/statuses/update.json");
var params:URLVariables = new URLVariables(
"include_entities=true&status=Maybe+he%27ll+finally+fiasdfasdfmnnd+his+kekjhjkys.+%23peterfalk&trim_user=true"+"&"+
    "status=Maybe+he%27ll+finally+fiasdfasdfmnnd+his+kekjhjkys.+%23peterfalk"+"&"+
    "trim_user=true"+"&"+
    "oauth_consumer_key=<myOauthConsumerKey>"+"&"+
    "oauth_nonce=<myOauthNonce>"+"&"+
    "oauth_signature=<myOauthSignature>"+"&"+
    "oauth_signature_method=HMAC-SHA1"+"&"+
    "oauth_timestamp=1331137102"+"&"+
    "oauth_token=<myOAuthToken>"+"&"+
    "oauth_version=1.0");
var loader:URLLoader = new URLLoader();

postTO.data=params;
postTO.method=URLRequestMethod.POST;
try {
    loader.load(postTO);
} catch (error:Error) {
    trace("Unable to load requested document.");
}

Review the crossdomain.xml file for the domain your accessing:

<cross-domain-policy xsi:noNamespaceSchemaLocation="http://www.adobe.com/xml/schemas/PolicyFile.xsd">
 <allow-access-from domain="twitter.com"/>
 <allow-access-from domain="api.twitter.com"/>
 <allow-access-from domain="search.twitter.com"/>
 <allow-access-from domain="static.twitter.com"/>
 <site-control permitted-cross-domain-policies="master-only"/>
 <allow-http-request-headers-from domain="*.twitter.com" headers="*" secure="true"/>
</cross-domain-policy>

Unless you are working for twitter and/or have access to serve your SWF off any of the allowed domains; you won't be able to build a browser based app that accesses these URLs directly from Flash You'll have to build a proxy in the server side language of your choice.
