oauth 2.0 - Google OpenId and Google APIs -

-

i trying achieve openid login google , acces token access google apis (such google plus, or drive)

the first attemp successful big problem:

  • make openid stuff, , user redirected google identify himself, return app identified.
  • make oauth stuff google apis, redirect user again identify himself , cameback code, exchange code access token needed call google apis.

the user needs identify twice. that's not good.

i read , tryed google hybrid openid , oauth. links there points deprecated oauth1 interface, , cant make work, user identified not request_token continue oauth stuff.

so have couple of questions:

  • is there way identify user agains google openid , @ same time users consent access google apis?
  • is hybrid protocol still working oauth2 , new google apis?
  • i'm on way or im missing something?

i need both openid , oauth beacouse application needs in google marketplace , must login users openid, , need hit apis need oauth2 access_token.

thanks!

why need work on both openid , oauth side side, , have 2 login screens? if use oauth 2.0 workflow, user needs key in credentials once , can want to.

once user consents login/permissions screen in oauth workflow, app access token. if need client info for, say, welcome user screen - need hit https://www.googleapis.com/oauth2/v1/userinfo endpoint access token , give user's public information. so, in short can pretty of things oauth flow, , user logging in once.

good luck! feel free follow more questions.

c++ - Function signature as a function template parameter -

i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...
