Observables return 类型
Observables return type
我正在将我的请求发送到 API 并使用映射函数对其进行解析:
//part of service
post(url: string, params): Observable<Response> {
let requestUrl: string = this.apiUrl + url;
return this.http.post(requestUrl, params)
.map(response => response.json());
}
//part of other service
doLogin(login, haslo): Observable<Response> {
return this.apiService.post('auth/login/', {login: login, haslo: haslo});
}
结果我得到一个布尔值并在订阅函数中使用它:
this.authService.doLogin(this.model.login, this.model.haslo)
.subscribe(result => {
//result is boolean - not Response
this.authService.loggedIn = result;
this.result = result
});
问题是在 doLogin
的订阅者中,TypeScript 说结果是 Response
而不是 boolean
- 我该如何解决这个问题?
这是你的函数原型的原因:
post(url: string, params): Observable<Response>
doLogin(login, haslo): 可观察<响应>
它们应该是:
可观察<布尔值>
这样做:
//part of service
post(url: string, params): Observable<any> {
let requestUrl: string = this.apiUrl + url;
return this.http.post(requestUrl, params)
.map(response => response.json());
}
//part of other service
doLogin(login, haslo): Observable<boolean> {
return this.apiService.post('auth/login/', {login: login, haslo: haslo})
.map(result => result == true /* or any check here and return an BOOLEAN !!*/);
}
