javascript - Overide Backbone sync globally with Browserify - 


var servicesnew = {     readurl :"",     deleteurl :"",     updateurl :"",     createurl :"",      primabackbone : function(method, model, options) {         options || (options = {});          var beforesend = options.beforesend;         options.beforesend = function(xhr) {            xhr.setrequestheader('authorization','bearer 52b20db1-4bcb-426e-9bbf-a53a826249f3')           if (beforesend) return beforesend.apply(this, arguments);         };         // passing options.url override          // default construction of url in backbone.sync          switch (method) {             case "read":                 options.url = readurl;                 break;             case "delete":                 options.url = deleteurl+'/'+model.get("id");                 break;             case "update":                 options.url = updateurl+'/'+model.get("id");                 break;              case "create":                 options.type = "put";                 options.url = createurl;                 break;             }          if (options.url)             return backbone.sync.call(model, method, model, options);     }     }  module.exports = servicesnew;

my model:

    // filename: models/project var backbone = require('backbone'),     urls= require('../../libs/urls'),     servicesnew = require('../../libs/servicesnew');  var notificationheadermodel = backbone.model.extend({        sync: function(){          servicesnew.readurl = urls.notifications.unread;         servicesnew.createurl = urls.notifications.list;         servicesnew.deleteurl = urls.notifications.list;         servicesnew.updateurl = urls.notifications.list;            return backbone.sync = servicesnew.primabackbone();        }   }); // return model module module.exports = notificationheadermodel;

in view:

    this.model.fetch({    success: function(model, response, options){      console.log(response);      _this.template = notificationtemplate;       _this.$el.html(_this.template({notificationdata: response,notificationtype:notifymsg.notificationtype()       ,notificationmessage:notifymsg.notificationmessage()}));    },    error: function(model, xhr, options){       alert(xhr.result.errors);   } });

i trying override backbone.sync method backbone globally unable so.

  1. i ditch attributes on servicesnew object , use options object pass urls
  2. your models' sync methods won't work that, you're reassigning backbone.sync , don't pass argument.

a potential solution be

var servicesnew = {     primabackbone : function(method, model, options) {         options || (options = {});          var beforesend = options.beforesend;         options.beforesend = function(xhr) {             xhr.setrequestheader('authorization','bearer 52b20db1-4bcb-426e-9bbf-a53a826249f3')             if (beforesend) return beforesend.apply(this, arguments);         };          switch (method) {             case "read":                 options.url = options.readurl;                 break;             case "delete":                 options.url = options.deleteurl+'/'+model.get("id");                 break;             case "update":                 options.url = options.updateurl+'/'+model.get("id");                 break;              case "create":                 options.type = "put";                 options.url = options.createurl;                 break;             }          if (options.url)             return backbone.sync.call(model, method, model, options);     } }

and model definition

var notificationheadermodel = backbone.model.extend({        sync: function(method, model, options){           options = _.defaults({}, options, {               readurl: urls.notifications.unread,               createurl: urls.notifications.list,               deleteurl: urls.notifications.list,               updateurl: urls.notifications.list           });            return servicesnew.primabackbone.call(model, method, model, options);       }  });

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: { ...
