为什么我收到错误...意外请求:GET/internalapi/quotes [英] Why do I receive error ... unexpected request: GET /internalapi/quotes

问题描述

我在我的 angular 应用中定义了以下服务:

I've defined the following service in my angular app :

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:

and I'm writing the following spec to test it :

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，第一个测试通过但第二个测试产生错误:

Whenever I run the tests, the first test passes but the second test produces the error :

错误:意外请求:GET/internalapi/quotes

我做错了什么?

结果我像这样配置了 Restangular ... RestangularProvider.setBaseUrl("/internalapi");.但我在伪造对 internalapi/quotes 的调用.注意缺少/".一旦我添加了斜线 /internalapi/quotes 一切都很好:)

It turned out I'd configured Restangular like so ... RestangularProvider.setBaseUrl("/internalapi");. But I was faking calls to internalapi/quotes. Notice the lack of the "/". Once I added the slash /internalapi/quotes all was good :)

推荐答案

你需要告诉 $httpBackend 期待一个 GET 请求.

You need to tell $httpBackend to expect a GET request.

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.我更喜欢将我的 whenGET() 语句放在 beforeEach() 中，这样我就不必在每个测试中定义响应.

Alternatively you can put your respond() on your expectGET(). I prefer to put my whenGET() statements in a beforeEach() that way I do not have to define the response within every test.

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

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