我正在尝试通过jasmine设置http GET请求期望,但我收到以下错误:
TypeError: Cannot read property 'user' of undefined
我想测试的服务功能如下:
function getData() {
return $http.get('http://example.com/data')
.then(function (response) {
return response.data.example.user;
});
}
网址“http://example.com/data”的 GET请求会返回以下数据:
{
"id": "1",
"example": {
"user": [
{
"name": "John",
"wife": [
{
"name": "Jane",
"age": "27"
}
]
}
}
}
相应的测试如下所示:
describe("Service: myService", function () {
beforeEach(module("myApp"));
var myService, $httpBackend;
beforeEach(inject(function (_myService_, _$httpBackend_) {
myService = _myService_;
$httpBackend = _$httpBackend_;
$httpBackend.whenGET("http://example.com/data").respond("some data");
}));
afterEach(function () {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
});
it("should call the correct URL", function() {
$httpBackend.expectGET("http://example.com/data");
myService.getData();
$httpBackend.flush();
});
不知何故,只要服务函数(我想测试)返回嵌套的JSON属性而不是整个JSON,我就无法测试http GET请求。
提前致谢!

API响应的数据应该是正确格式的模拟数据,此处getData
是方法期望的对象格式,因此可以从中返回用户。比如response.data.example.user
<强>代码强>
$httpBackend.whenGET("http://example.com/data").respond({
"id": "1",
"example": {
"user": [] //to keep you code working
}
})
