类型为"可观察"的参数<LoginRequest>不能分配给类型为"登录请求"的参数

Question

我正在尝试使用Karma/Jasmine进行单元测试，我得到了错误

类型为"Observable"的参数不可分配给类型为"LoginRequest"的参数。类型"Observable"中缺少属性"userid">

我在调用service.login(loginRequest);的login.service.spec.ts中的编译时出错。

login.service.spec.ts

import { ComponentFixture, TestBed, inject } from '@angular/core/testing';
import { ApiConnectorService } from '../api-handlers/api-connector.service';
import { LoginService } from './login.service';
import { HttpClient, HttpHandler } from '@angular/common/http'; 
import { Observable } from 'rxjs';
import { of } from 'rxjs/observable/of';
import { LoginResponse, LoginRequest } from './login.contract';

class ApiConnectorServiceStub {
constructor() { }
post(address: string, payload: LoginRequest): Observable<LoginResponse> {
let str:LoginResponse = {token:'success'};
return  of(str);
}
}
describe('LoginService', () => {
let service: LoginService;
let fixture: ComponentFixture<LoginService>;
beforeEach(() => {
TestBed.configureTestingModule({
providers: [LoginService, ApiConnectorService, HttpClient, HttpHandler,
{provide: ApiConnectorService, useClass: ApiConnectorServiceStub}]
});
});
it('should be created', inject([LoginService], (service: LoginService) => {
expect(service).toBeTruthy();
}));
it('should call post on apiConnectorService with right parameters when login is called',
inject([LoginService], (service: LoginService) => {
const apiConnectorStub = TestBed.get(ApiConnectorService);
const str:LoginResponse = {token:'success'};
const spy = spyOn(apiConnectorStub, 'post').and.returnValue(of(str));
const lRequest: LoginRequest={userid:'[e-mail]',password:'hsjshsj',newpassword:'hsjshsj'};
const loginRequest = of(lRequest);
service.login(loginRequest);
expect(spy).toHaveBeenCalledWith('/api/login', loginRequest);
})); 
});

登录.service.ts

import { Injectable } from '@angular/core';
import { ApiConnectorService } from '../api-handlers/api-connector.service';
import { LoginRequest, LoginResponse } from './login.contract';
import { Observable } from 'rxjs/Observable';
import { map } from 'rxjs/operators';
import * as marked from 'marked';
@Injectable()
export class LoginService {
constructor(private apiConnector: ApiConnectorService) { }
login(payload: LoginRequest): Observable<LoginResponse> {
console.log('Login payload ', payload);
return this.apiConnector.post('/api/login', payload)
.pipe(
map((data: LoginResponse) => data)
)
}
}

登录合同.ts

export interface LoginRequest {
env?: string;
userid: string;
password: string;
newpassword: string;
}
export interface LoginResponse {
token: string;
}

api-connector.service.ts

import { Injectable } from '@angular/core';
import { HttpClient, HttpParams } from '@angular/common/http';
import { ErrorObservable } from 'rxjs/observable/ErrorObservable';
import { Observable } from 'rxjs/Observable';
import {environment} from '../../../environments/environment';
import { catchError } from 'rxjs/operators/catchError';

@Injectable()
export class ApiConnectorService {
constructor(private http: HttpClient) { }
private  getQueryString(params): string {
const queryString = Object.keys(params).map(key => key + '=' + params[key]).join('&');
console.log('QUERY STRING', queryString);
return ('?' + queryString);
}
private formatErrors(error: any) {
return new ErrorObservable(error.error);
}
post(path: string, body: Object): Observable<any> {
// console.log('API SERVICE BODY', body)
return this.http.post(
`${environment.base_url}${path}`,
body
).pipe(catchError(this.formatErrors));
}
}

在测试中，触摸正在进行

const loginRequest = of(lRequest);
service.login(loginRequest)

但是登录方法将LoginRequest作为参数-您正试图通过Observable

所以改变

const loginRequest = of(lRequest);

至

const loginRequest = lRequest;
