Question

如何在使用OData数据服务时告诉Breeze包含授权持有者令牌标头？

//Configured breeze to use OData
breeze.config.initializeAdapterInstance('dataService', 'OData');

//Configured breeze to use AngularJS ajax
var instance = breeze.config.initializeAdapterInstance('ajax', 'angular', true);

//Tried passing authorization bearer token header using setHttp with no success
//NOTE: $http setup with $http.defaults.headers.common['Authorization'] = 'Bearer...'
instance.setHttp($http);

//Tried passing authorization bearer token header using ajax settings with no success
instance.defaultSettings = {
    headers: {
        'Authorization': 'Bearer...'
    },
};

//Fiddler shows no authorization bearer token header for following query
var manager = new breeze.EntityManager('/odata/');
var query = breeze.EntityQuery.from('Customers');
return manager.executeQuery(query).to$q(querySucceeded, queryFailed);

我不知道你是否解决了问题。这对我有用：

function configureBreeze() {
            // configure to use the model library for Angular
            breeze.config.initializeAdapterInstance("modelLibrary", "backingStore", true);

            var accessToken = Security.user.access_token;

            if (Security.user.access_token) {
                // get the current default Breeze AJAX adapter & add header required for the         Web API bearer token mechanism
                var ajaxAdapter = breeze.config.getAdapterInstance("ajax");
                ajaxAdapter.defaultSettings = {
                    headers: {

                        'Authorization': 'Bearer ' + accessToken
                    },
                };
            }
        }

它是对asp.net MVC4的Angular/Breeze SPA template的datacontext.js脚本中的configureBreeze方法的修改。

希望它有所帮助。

我遇到了同样的问题。在查看oData的breeze dataservice后，我认为它只是忽略了ajax提供程序，因为它使用 datajs 来执行请求。所以instance.setHttp($http);将不起作用。我最终覆盖了 datajs 中的默认request方法：

    var base = window.OData.request;
    window.OData.request = function (request, success, error, handler, httpClient, metadata) {
        angular.extend(request.headers, { Authorization: $rootScope.token });
        return base(request, success, error, handler, httpClient, metadata);
    };

Breeze网站上有一个样本（在OData AJAX下）：http://www.getbreezenow.com/documentation/controlling-ajax

var oldClient = OData.defaultHttpClient;

var myClient = {
     request: function (request, success, error) {
         request.headers.Authorization = authorization;
         return oldClient.request(request, success, error);
     }
};

OData.defaultHttpClient = myClient;

Answer 4

//instance.defaultSettings = {
//    headers: {
//        'Authorization': 'Bearer...'
//    },
//};

instance.headers['Authorization'] = 'Bearer...';

使用BreezeJS OData数据服务传递授权承载令牌
