I create a jsp project about twitter api.When I run it on my own local jsp server,tomcat,it works correctly.So I upload it to google app engine.On the app engine,If I visit the unnecessary authorized api,such as public_timeline,it works well.But when it need authorize,such as home_timeline,it always response the 'Invalid / used nonce' error.Why?
here is the location detail: my location:China google app engine's location:may be US,absolutely not in China When program get the access_token,it will send request to home_timeline. There are two http head from twitter api via two different web server: google app engine: OAuth oauth_consumer_key="9WXY7kD9XiznbN4zRMyNuA", oauth_nonce="92fa4a6aa648672cf26dbb05a9b4a744", oauth_signature="iq9N97qB1x9Ae251cxv%2Bvvmyjn0%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1276437638", oauth_token="154805754-WwhuUbBdwmfOcajq0jxfDg4Ers8St4N6lHe3FmrU", oauth_version="1.0" my local tomcat: OAuth oauth_consumer_key="9WXY7kD9XiznbN4zRMyNuA", oauth_nonce="4e3de3e506b8cf961d3d02d2aca1c8ed", oauth_signature="860zZiqdK9DuXOvUDBLZMMhgm2M%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1276437655", oauth_token="154805754-WwhuUbBdwmfOcajq0jxfDg4Ers8St4N6lHe3FmrU", oauth_version="1.0" part of code: tk = sb.getAccessToken(tk, pin); req = new Request(Request.Verb.GET,"http://api.twitter.com/statuses/ home_timeline.xml"); sb.signRequest(req, tk); resp = req.send(); out.println(resp.getBody()); res=req.getHeaders().get("Authorization"); System.out.println(res); ps: pin is the user authorized code, tk is the access_token, signRequest means add the tk to request stream, the result will be printed to the web browser, res is the http header which like I mentioned above. Need any more infomation? Thanks for tolerating my ravings
