java - 400 Error "error_description" : "Invalid grant_type: urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer" Google Service account -


i following tutorial https://developers.google.com/accounts/docs/oauth2serviceaccount authorise application. have created jwt following tutorial.

but when make access token request keep on getting "invalid grant_type: urn%3aietf%3aparams%3aoauth%3agrant-type%3ajwt-bearer" exception.

here code make request

httpclient httpclient = new httpclient();         postmethod post = new postmethod("https://accounts.google.com/o/oauth2/token");         post.addrequestheader("content-type", "application/x-www-form-urlencoded");         post.addparameter("grant_type", urlencoder.encode("urn:ietf:params:oauth:grant-type:jwt-bearer", "utf-8"));         post.addparameter("assertion", "jwt including signature.");         httpclient.executemethod(post);

i have looked @ lot of resources bu obvious error seems mistaking client id email id. however, have checked , re-cheeked make sure using correct one.

please can tell me doing wrong.

many thanks

i solved referring post: invalid grant error being thrown while retrieving accesstoken google service account request.

turns out there problem ntp(network time protocol). expiration time , issued @ time had changed. after did that, start work properly.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
