我遇到HttpHeaders(angular 4.3.0)和Karma的问题。我编写了一些测试,当我使用npm test命令运行它们时,http查询未经授权,因为未设置令牌(X-Auth-Token)。当我在浏览器中使用控制台运行相同的部件时,X-Auth-Token已设置好,一切正常。
我能看到的唯一区别是在HttpHeaders对象中,恰好在lazyUpdate中。

代码:
category.service.spec.ts
describe('Service : Category', () => {
// setup
beforeEach(() => TestBed.configureTestingModule({
imports: [ HttpClientModule, LocalStorageModule.withConfig(localStorageConfig), TranslateModule.forRoot({
loader: { provide: TranslateLoader, useClass: TranslateFakeLoader }
})],
providers: [CategoryService, LoaderService, LocalStorageService
]
}));
it('should list the categories', () => {
let categoryService = TestBed.get(CategoryService);
categoryService.apiRoutes = ApiCategoryRoutes;
categoryService.modelName = "category";
let actualCategories = [];
// categoryService expends APIResolverService
let observable = categoryService.find();
observable.subscribe(data => {
actualCategories = data;
});
console.log("actualCategories");
console.log(actualCategories);
});
});
apiResolver.service.ts(categoryService扩展它,类别服务没有特定代码)
export abstract class APIResolverService {
...
public find() {
this.showLoader();
let url = this.getUrl(0, true);
let headers = this.setHttpHeaders();
console.log("headers");
console.log(headers);
let observable = this.http.get(url, {headers : headers})
.map(res => this.manageResponse(res, true, true)).share();
observable.subscribe(data => this.hideLoader(), error => this.hideLoader());
return observable;
}
...
public setHttpHeaders(){
let valueToken: string = JSON.stringify(this.localStorage.get('token'));
let myHeaders = new HttpHeaders()
.set('Content-Type', 'application/json')
.set('Accept', 'application/json')
.set('Accept-Language', "en")
.set('X-Auth-Token', valueToken.replace(/['"]+/g, ''));
return myHeaders;
}
}
有人可以解释一下吗?
答案 0 :(得分:0)
在测试设置了一些请求标头的拦截器时,我遇到了类似的问题。我在测试中做错的是没有设置标头之一(留给undefined
)-我没有深入研究Angular代码,但这似乎忽略了将'lazyInit'属性设置为{ {1}},该位置将停止触发“ init”调用(基本上设置了标头):
null
github上有一个问题涉及到此。请参阅this评论。
