Howdy,
I'm brand new to GAE/Java dev, and wish to ask a few questions about a
simple test code fragment I just deployed. This (very simple) code
fragment might help someone implement OAuth when integrating GAE with
Google App Script. I've seen parts of it in a few places, but never
in a complete example. I needed a way to authenticate a Google Docs
user with my application to restrict access.
The code on the Google App Script side of things:
/***************/
function authentication() {
var oAuthConfig = UrlFetchApp.addOAuthService("google"), utc = (new
Date()).toUTCString();
oAuthConfig.setAccessTokenUrl("https://<APP-ID>.appspot.com/_ah/
OAuthGetAccessToken");
oAuthConfig.setRequestTokenUrl("https://<APP-ID>.appspot.com/_ah/
OAuthGetRequestToken");
oAuthConfig.setConsumerKey('anonymous');
oAuthConfig.setConsumerSecret('anonymous');
var requestData = {
"method": "GET",
"oAuthServiceName": "google",
"oAuthUseToken": "always"
};
var response = UrlFetchApp.fetch('http://<APP-ID>.appspot.com/<THE-
URI>', requestData).getContentText();
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var lastRow = sheet.getLastRow();
sheet.getRange(lastRow + 1, 1).setValue(utc);
sheet.getRange(lastRow + 1, 2).setValue(response);
}
/***************/
On GAE:
/***************/
package mypackage;
import java.io.IOException;
import java.util.Date;
import javax.servlet.http.*;
import com.google.appengine.api.users.User;
import com.google.appengine.api.oauth.OAuthService;
import com.google.appengine.api.oauth.OAuthServiceFactory;
public class AppScriptServerServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
User user = null;
Date date = new Date(System.currentTimeMillis());
try {
OAuthService oauth =
OAuthServiceFactory.getOAuthService();
user = oauth.getCurrentUser();
resp.getWriter().println("Request time: " +
date.toString() + " User: " + user.getNickname());
} catch (Exception e) {
resp.getWriter().println("Request time: " + date.toString() +
" Exception: " + e.toString());
}
}
}
/***************/
My 2 questions:
1. I have set up a time driven trigger on GAS to execute the script
every minute. It seems I get current Date values from the GAE app
every 6 minutes +-6 seconds (very monotonously):
Fri, 01 Apr 2011 20:05:12 GMT :::::: "Request time: Fri Apr 01
20:01:14 UTC 2011 User: [email protected]"
Fri, 01 Apr 2011 20:06:12 GMT :::::: "Request time: Fri Apr 01
20:01:14 UTC 2011 User: [email protected]"
Fri, 01 Apr 2011 20:07:12 GMT :::::: "Request time: Fri Apr 01
20:07:14 UTC 2011 User: [email protected]"
Fri, 01 Apr 2011 20:08:12 GMT :::::: "Request time: Fri Apr 01
20:07:14 UTC 2011 User: [email protected]"

Fri, 01 Apr 2011 20:12:12 GMT :::::: "Request time: Fri Apr 01
20:07:14 UTC 2011 User: [email protected]"
Fri, 01 Apr 2011 20:13:12 GMT :::::: "Request time: Fri Apr 01
20:13:15 UTC 2011 User: [email protected]"
Fri, 01 Apr 2011 20:14:12 GMT :::::: "Request time: Fri Apr 01
20:13:15 UTC 2011 User: [email protected]"
What am I doing wrong? (if it's Java related, very sorry, my last Java
classes date back more than 6 minutes ago);
2. This very simple app generates a lot of CPU time. From the GAE
Dashboard:
/<MY-URI> :::::: 36 [requests] :::::: 1741 (0) [Avg CPU
(API)] :::::: 100% [% CPU]
The Quota Details page is more reassuring: my immediate CPU Quota is
"Okay".
Am I right to think this is a discrepancy? Aren't both of these
values a short-time average (over a minute)? I guess I'll trust the
value I like best: "Okay"
Thanks
