angularjs - 为什么我收到错误...意外请求 : GET/internalapi/quotes

Question

我在我的 Angular 应用程序中定义了以下服务:

services.factory('MyService', ['Restangular', function (Restangular) {
       return {
           events : { loading : true },

           retrieveQuotes : function() {
               return Restangular.all('quotes').getList().then(function() {
                   return { hello: 'World' };
               });
           }
    };
}]);

我正在编写以下规范来测试它:

describe("MyService", function () {

    beforeEach(module('MyApp'));
    beforeEach(module("restangular"));

    var $httpBackend, Restangular, ms;

    beforeEach(inject(function (_$httpBackend_, _Restangular_, MyService) {
        ms = MyService;
        $httpBackend = _$httpBackend_;
        Restangular = _Restangular_;
    }));


    it("retrieveQuotes should be defined", function () {
        expect(ms.retrieveQuotes).toBeDefined();
    });

    it("retrieveQuotes should return array of quotes", function () {

        $httpBackend.whenGET("internalapi/quotes").respond({ hello: 'World' });
        ms.retrieveQuotes();
        $httpBackend.flush();
    });

});

每当我运行测试时，第一个测试就会通过，但第二个测试会产生错误:

错误:意外请求:GET/internalapi/quotes

我做错了什么？

编辑:

结果我像这样配置了 Restangular ... RestangularProvider.setBaseUrl("/internalapi");。但我伪造了对 internalapi/quotes 的调用。注意缺少“/”。一旦我添加了斜杠 /internalapi/quotes 一切都很好:)

您需要告诉 $httpBackend 期待 GET 请求。

describe("MyService", function () {

   beforeEach(module('MyApp'));
   beforeEach(module("restangular"));

   var Restangular, ms;

    beforeEach(inject(function (_Restangular_, MyService) {
        ms = MyService;

        Restangular = _Restangular_;
    }));


    it("retrieveQuotes should be defined", function () {
        expect(ms.retrieveQuotes).toBeDefined();
    });

    it("retrieveQuotes should return array of quotes", inject(function ($httpBackend) {

        $httpBackend.whenGET("internalapi/quotes").respond({ hello: 'World' });

        //expect a get request to "internalapi/quotes"
        $httpBackend.expectGET("internalapi/quotes");

        ms.retrieveQuotes();
        $httpBackend.flush();
    }));

});

或者，您可以将 respond() 放在 expectGET() 上。我更喜欢将 whenGET() 语句放在 beforeEach() 中，这样我就不必在每个测试中定义响应。

        //expect a get request to "internalapi/quotes"
        $httpBackend.expectGET("internalapi/quotes").respond({ hello: 'World' });

        ms.retrieveQuotes();
        $httpBackend.flush();
