javascript - Generating a unique value for a header on each $http call -


i have large angularjs application , logging purposes, being tasked adding custom header of our http requests app contain a unique id each request. more valuable our api calls, of i'm aiming requests (getting templates, styles, etc.)

i using provider decorator patch each of methods exposed $httpprovider (implementation based on this post), attempt call id method each time 1 of $http methods runs, , add appropriate header:

module.config([   '$provide',   function ($provide) {     $provide.decorator('$http', [       '$delegate',       function adduniqueidheader($http) {         var httpmethods = ['get', 'post', 'put', 'patch', 'delete'];          /**          * patched http factory function adds request id each time called.          * @param  {string} method - valid http method.          * @return {function} function sets various request properties.          */         function httpwithheader(method) {           return function(url, data, config) {             config = config || {};             config.headers = config.headers || {};              // magic             config.headers['my-custom-header'] = auniqueid();              data = data || {};              config.method = method.touppercase();              // return `$http` modified config, adding url , data passed in             // `_.extend()` lodash, not underscore.             return $http(_.extend(config, {               url: url,               data: data             }));           }         };          // orginal methods , patch         _.each(httpmethods, function (httpmethod) {           var backupmethod = '_' + httpmethod;            $http[backupmethod] = $http[httpmethod];           $http[httpmethod] = httpwithheader(httpmethod);         });          return $http;       }     ]);   } ]);

what have far works of time, doesn't seem work consistently (some api requests have it, don't). should note using quite old version of angularjs (1.0.6) , no, cannot upgrade (as love to) use of request interceptors not possible. additionally, use restangular majority of our api interactions.

my question is, using provider decorator right way go? if so, there cleaner way add header without having override/patch each individual http method i'm overlooking?

thanks in advance.

i ended solving issue utilizing restangular's request interceptors, since version of angular use doesn't have them baked in.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
