Problem with the sending of paramaters to rbv_api.sendhttpPo

Hi .

How do i send the header information like headers for authorization...I tried sending it in header={"Authorization " : "......"} format ...but i am recieving errors...Should i be sending in key value pair itself or does Oauth require some other format.... I have also seen some others having the same problem...but with paypal api...

And also I have tried to write the ajax request as i did'nt know the inner mechanism of the rbv_api calls....But jt has difficulty requesting(GET,POST) apis for security reasons.. No 'Access-Control-Allow-Origin' is the errror if i am using manual javscript rather than using rbv_api calls....

Please help me with the rbv_api calls or the manual ajax calls 

My code

var url="https://api.twitter.com/1.1/statuses/update.json";
var params={"status":"Hiii"};
var key="OAuth oauth_consumer_key=/"ydpaKblD5OKK3kW2TRuscej1P/", oauth_nonce=/"539c9b13e0e76f4bfdb4f1c462ff97d7/", oauth_signature=/"oaOSVDDvx3EfUPRCunZU%2FHkqir0%3D/", oauth_signature_method=/"HMAC-SHA1/", oauth_timestamp=/"1402394771/", oauth_token=/"581185549-BeGt5lT3dIFSHHD9vll4tYkazpPgpGaj1Fixl3ki/", oauth_version=/"1.0/" ";
var headers={
"content-Length":params.length,
"content-Type":"jsonp",
"Connection":"close"
"Authorization":key
};

var body=rbv_api.sendHttpPost(url,params,headers);

rbv_api.setSharedValue("response",body);
var json=rbv_api.stringToJson(body);

return body;

Plss help :)
