HI,
Now I remember why I choose AuthSub : AuthSub is documented in AppEngine
docs, where OAuth is not (or not so)
It is a nightmare to try to understand how OAuth must be implemented in
Java...and that's don't work yet.
I have trying to use OAuth using a third lib "Scribe" for the OAuth
protocol.
Here is my code :
String scope =
"http://www.google.com/calendar/feeds/default/allcalendars/full";;
String RequestBackUrl =
"http://timegrouper2011.appspot.com/RetrieveTokenOAuth?back=y";;
if (get("back").equals("y")) { // step 2
echoln("GET BACK TOKEN...");
OAuthService service = new ServiceBuilder() // 'scribe
service
.provider(GoogleApi.class)
.apiKey("timegrouper2011.appspot.com")
.apiSecret("xxxxxxxxxxxxxxxxxxxx") // here stand my
api secretprovided by Google after registration
.callback(RequestBackUrl)
.scope(scope) //
calendar scope
.build();
Token requestToken = service.getRequestToken(); // basic
token (for what use here ? ) hmmm
String verifierStr = get("oauth_verifier");
// verifier from url
String authToken = get("oauth_token"); //
oauthtoken from url
Verifier verifier = new Verifier(verifierStr);
resp.getWriter().println("QueryString back verifier : " +
verifierStr + "<br>");
resp.getWriter().println("QueryString back auth : " + authToken
+ "<br>");
resp.getWriter().println("Service request token : " +
requestToken + "<br>");
Token accessToken;
try {
accessToken = service.getAccessToken(requestToken,
verifier);
} catch (Exception e) {
this.error("auth Tokenerror : " + e.toString() + "<br>");
return;
}
resp.getWriter().println("<br><br><table>");
resp.getWriter().println("<tr>td>Token non auth :</td><td> " +
requestToken + "</tr></tr>");
resp.getWriter().println("<tr>td>Token reply :</td><td> " +
authToken + "</tr></tr>");
resp.getWriter().println("<tr>td>auth Token : </td><td> " +
accessToken + "</tr></tr>");
resp.getWriter().println("</table>");
}
else {
// STEP 1
// String scope =
"https://www.google.com/calendar/feeds/";;
OAuthService service = new ServiceBuilder()
.provider(GoogleApi.class)
.apiKey("timegrouper2011.appspot.com")
.apiSecret("xxxxxxxxxxxxxxxxxxxx")
.callback(RequestBackUrl)
.scope(scope) // il parait qu'il faut
pas le mettre mais sinon erreur...mais pourtant c'est l'inverse
.build();
Token requestToken = service.getRequestToken();
String your_token = requestToken.getToken();
resp.getWriter().println("Token : " + your_token);
String step2url
="https://www.google.com/accounts/OAuthAuthorizeToken";;
step2url = step2url + "?oauth_token="+your_token;
resp.getWriter().println("<br>Token auth url : <br><a href='" +
step2url + "'>Log me in...</a>");
}
Something go wrong on step 2 :
Exemple of result :
GET BACK TOKEN...
QueryString back verifier : VO9K5Ykeu4zgFzpihAlsRGev
QueryString back auth : 4/qaWXlhxFvuWCenYtCWKZkEz7cU7G
Service request token : Token[4/ijJxtFuBJMvkA-7bmF7Ihk5XpgMX ,
vIzcE+IjLrGxz0w+5jJ96+Lh]
ERROR : auth Tokenerror : org.scribe.exceptions.OAuthException: Response
body is incorrect. Can't extract a token from this: 'The token is invalid. '
Any idea of what's I'm doing wrong ?
Thanks,
tleboulay
