maybe should ask intended use of identity token is. thought used identify user , can passed other services (e.g. backend services) , services use id_token validate valid user? don't see current available endpoint validate id_token. if not, should passed 1 service service validate user? the end point takes id_token parameter end session endpoint passed id_token_hint. in case, why identitytokenlifetime default 300 sec only? don't expect user end session in 300 sec. the identity token one-time token. it contains identity of user , authentication metadata. once token validated, (in theory) deleted. pick out claims interested in. the situation want keep identity token around special features during sign-out. the identity token never passed around. that's access token for.

i want create sumifs condition can refer both arguments. want able "if month , year of first argument equal month , year of second argument." however, examples of sumifs i've seen have condition such "=food", can't perform function on other argument. how can accomplished? sumproduct more powerful sumifs, although harder understand. =sumproduct( month(b1:b20)=month(d1), year(b1:b20)=year(d1), c1:c20 ) this checks rows 1 20 see if month of date in column b equal month of d1, , likewise year. if both equal, sums value column c of row. details on how sumproduct works : if either month or year not equal, result of first or second array row zero. gets multiplied whatever in column c, resulting in zero. value gets summed row zero; in other words, ignored.

following spring integration ftp doc , have managed send files ftp server through java config way: @messaginggateway public interface mygateway { @gateway(requestchannel = "toftpchannel") void sendtoftp(file file); } ss public static void main(string[] args) { configurableapplicationcontext context = new springapplicationbuilder(ftpjavaapplication.class) .web(false) .run(args); mygateway gateway = context.getbean(mygateway.class); // sending file ftp server gateway.sendtoftp(new file("/foo/bar.txt")); } it seems me code above using custom method 'sendtoftp()' send file target ftp server. question how add other methods mygateway interface implement operations? ls (list files) (retrieve file) mget (retrieve file(s)) rm (remove file(s)) mv (move/rename file) put (send file) mput (send multiple files) each ftp gateway can handle 1 method. you need ...

this question has answer here: javascript closure inside loops – simple practical example 31 answers i have snippet of code for(var i=0; < this.arr2.length; i++) { arr.push({ id: i.tostring(), label: this.arr2[i], display: () => this.arr2[i] }) } why display undefined if doing let val = this.arr2[i]; display: () => val is working fine you should use let keyword in order declare block scope local variable for(let = 0; < this.arr2.length; i++) { arr.push({ id: i.tostring(), label: this.arr2[i], display: () => this.arr2[i] }) } for example use map method. the map() method creates new array results of calling provided function on every element in calling array. arr=arr2.map(function(item,i){ return {id:i,label:item,display:()=>item}; }); short exam...

i trying set easylogging++ in project, , run following issue: macro initialize_easyloggingpp should called once in project. now, if call macro main.cpp , include easylogging++.h in main.cpp - works fine. however, when try include easylogging++.h in more .cpp files, linker issues undefined references (as if macro hasn't been called). if place call macro in file alphabetically before main.cpp , linker resolves normally. in linking phase objects sorted alphabetically. is there nice way solve issue? or have try force different order of files @ linking time? i not experienced sort of issues, tried googling it, couldn't find solution. if there similar question, sorry, couldn't find it. thanks help! maybe wrap call in function invoke using std::call_once() , example: void setup_logging() { static std::once_flag once; std::call_once(once, [] () { initialize_easyloggingpp(); }); } that way can call setup_logging() multiple times, macro invoked on...
