GTM OAuth for IOS not working with Grails OAuth 2 provider -
i working on ios app , want use oauth authenticate app grails system have in place. grails system has oauth2 provider setup using plugin @ link below:
https://github.com/adaptivecomputing/grails-spring-security-oauth2-provider the oauth provider setup , work have tested url's shown below , authorisation code expected once access has been granted:
http://localhost:8080/app/oauth/authorize?response_type=code&client_id=clientid&redirect_uri=http://localhost:8080/app/ the issue having when use gtm oauth plugin ios google have set follows:
static nsstring *const kmyclientid = @"1"; static nsstring *const kmyclientsecret = @"secret"; static nsstring *const kkeychainitemname = @"systemkeychain"; - (gtmoauth2authentication *)systemauth { // set token url system token endpoint. nsurl *tokenurl = [nsurl urlwithstring:@"http://www.systemurl.co.uk/oauth/token"]; // set bogus redirect uri. won't used redirect // intercepted oauth library , handled in app. nsstring *redirecturi = @"http://www.systemurl.co.uk/"; gtmoauth2authentication *auth; auth = [gtmoauth2authentication authenticationwithserviceprovider:@"system api" tokenurl:tokenurl redirecturi:redirecturi clientid:kmyclientid clientsecret:kmyclientsecret]; return auth; } - (void)authorize:(nsstring *)service { gtmoauth2authentication *auth = [self systemauth]; // prepare authorization url. pass in name of service // wish authorize with. nsurl *authurl = [nsurl urlwithstring:[nsstring stringwithformat:@"http://www.systemurl.co.uk/oauth/authorize"]]; // display authentication view gtmoauth2viewcontrollertouch *viewcontroller; viewcontroller = [ [gtmoauth2viewcontrollertouch alloc] initwithauthentication:auth authorizationurl:authurl keychainitemname:kkeychainitemname delegate:self finishedselector:@selector(viewcontroller:finishedwithauth:error:)]; [viewcontroller setbrowsercookiesurl:[nsurl urlwithstring:@"http://www.systemurl.co.uk/"]]; // push authentication view our navigation controller instance [ [self navigationcontroller] pushviewcontroller:viewcontroller animated:yes]; } - (void)viewcontroller:(gtmoauth2viewcontrollertouch *)viewcontroller finishedwithauth:(gtmoauth2authentication *)auth error:(nserror *)error { if (error != nil) { // authentication failed uialertview *alertview = [ [uialertview alloc] initwithtitle:@"authorization failed" message:[error localizeddescription] delegate:self cancelbuttontitle:@"dismiss" otherbuttontitles:nil]; [alertview show]; } else { // authentication succeeded // assign access token instance property later use self.accesstoken = auth.accesstoken; // display access token user uialertview *alertview = [ [uialertview alloc] initwithtitle:@"authorization succeeded" message:[nsstring stringwithformat:@"access token: %@", auth.accesstoken] delegate:self cancelbuttontitle:@"dismiss" otherbuttontitles:nil]; [alertview show]; } } the issue when run code above redirects me system fine , log in, page comes me grant access app , click "authorize" , app shows me alert view error 500 in it.
so went grails system , looked @ logs see happened , noticed url being passed in app was:
"get /oauth/authorize?client_id=1&redirect_uri=http%3a%2f%2fwww.systemurl.co.uk%2f&response_type=code http/1.1" 302 - "get /oauth/authorize?client_id=1&redirect_uri=http%3a%2f%2fwww.systemurl.co.uk%2f&response_type=code http/1.1" 200 6923 "post /oauth/authorize?client_id=1&redirect_uri=http%3a%2f%2fwww.systemurl.co.uk%2f&response_type=code http/1.1" 302 - and error 500 message shown below system:
2014-03-24 08:25:53,081 [http-8080-2] error errors.grailsexceptionresolver - nosuchclientexception occurred when processing request: [post] /oauth/token - parameters: client_secret: secret grant_type: authorization_code redirect_uri: http://www.systemurl.co.uk/ code: 4bf5se client_id: 1 no client requested id: testing. stacktrace follows: org.springframework.security.oauth2.provider.nosuchclientexception: no client requested id: testing @ grails.plugin.cache.web.filter.pagefragmentcachingfilter.dofilter(pagefragmentcachingfilter.java:179) @ grails.plugin.cache.web.filter.abstractfilter.dofilter(abstractfilter.java:63) @ grails.plugin.springsecurity.web.filter.grailsanonymousauthenticationfilter.dofilter(grailsanonymousauthenticationfilter.java:53) @ grails.plugin.springsecurity.web.authentication.requestholderauthenticationfilter.dofilter(requestholderauthenticationfilter.java:49) @ grails.plugin.springsecurity.web.authentication.logout.mutablelogoutfilter.dofilter(mutablelogoutfilter.java:82) @ java.lang.thread.run(thread.java:722) now error above suggest me reason username being used client id somehow , don't know why, username , password "testing" on grails system.
can please offer advise on why might happening?
thanks in advance
***edit*****
i have debugged http requests being sent , below raw request being sent token:
post /oauth/token http/1.1 host: www.systemurl.co.uk accept-encoding: gzip, deflate content-type: application/x-www-form-urlencoded accept-language: en-us cookie: jsessionid=70eb045c21084e166a34eda88fe155c8.28151 accept: */* content-length: 130 connection: keep-alive user-agent: gtm-oauth2 com.test.oauthgtm/1.0 client_id=1&client_secret=secret&code=vayn8m&grant_type=authorization_code&redirect_uri=http%3a%2f%2fwww.systemurl.co.uk%2f
the short answer is: "client_id=public", works
the long answer:
if debug through code, you'll find out exception thrown in inmemoryclientdetailsservice.
in grails version 2.2.4 code looks this
private map<string, ? extends clientdetails> clientdetailsstore = new hashmap<string, clientdetails>(); public clientdetails loadclientbyclientid(string clientid) throws oauth2exception { clientdetails details = clientdetailsstore.get(clientid); if (details == null) { throw new invalidclientexception("client not found: " + clientid); } return details; } in map clientdetailsstore 1 value "public"
