What are you using to issue the requests? What API call are you making?

while sending http request to twitter , it gives this error
Twitter.TwitterApiException: Status: 500 Internal Server Error Content-Type: text/html

500 Internal Server Error

my request format is

        string LogedInUser;
        LogedInUser=Userinfo.getuserId();
        Twitter.Share s = new Twitter.Share(); 
        Twitter link= new Twitter(LogedInUser); 
        s.text= 'Job vacancy';
        s.related='TestJob';
        s.url='www.google.com';
        link.updateUserShare(s);

my share class is

public class Share
{
public String text{get;set;}
public String related{get;set;}
public String url{get;set;}

    public Share()
    { }
    
    public DOM.Document toXML()
    {
        DOM.Document doc = new DOM.Document();
        Dom.XmlNode req=doc.createRootElement('tweet', null, null);

        if (text!= null || related!= null || url != null)
        {
            Dom.XmlNode body;
            body= req.addChildElement('text', null, null).addTextNode(text);
            body= req.addChildElement('related', null, null).addTextNode((related != null)?related:'');
            body= req.addChildElement('url', null, '').addTextNode((url != null)?url:'');
        }
        return doc;
    }
}

I want twitter status should be updated with the given text and url. i m using beta 1.0 sfdc-OAuth Playground package.
I think there is a problem in toXML() method, please look into it.

Thanks!

create http request method

protected virtual HttpRequest createRequest(String path, String method, DOM.Document request)
{
HttpRequest req = new HttpRequest();
req.setEndpoint(‘https://twitter.com’ + path);
req.setMethod(method == null ? ‘GET’ : method);
req.setHeader(‘Content-Type’, ‘text/xml’ );
req.setTimeout(60000);
req.setBodyDocument(request);

    if (oa == null)
    {
        oa = new OAuth();
        if (!oa.setService('Twitter', sfdcUserId))
        {
            throw new AuthenticationException(oa.message);
        }
    }
    
    oa.sign(req);
    return req;
}

execute http request

protected virtual HttpResponse executeLinkedInRequest(HttpRequest req)
{
HttpResponse res = new Http().send(req);
if (req.getMethod() == ‘POST’ && res.getStatusCode() != 201)
{
throw new TwitterApiException (res.getBody()); // shows exception on this line.
}
else if (req.getMethod() == ‘GET’ && res.getStatusCode() != 200)
throw new TwitterApiException (res.getBody());

    return res;
}
