Observables返回类型

Question

我将请求发送到API并使用map函数解析它：

//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});
}

结果我获得了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doLogin的订阅者TypeScript说结果是Response而不是boolean - 如何解决？

Answer 1

你的功能原型的原因：

post（url：string，params）：Observable＆lt; Response ＆gt;

doLogin（login，haslo）：可观察＆lt; 响应＆gt;

他们应该是：

可观察＆LT;的布尔＆GT;

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 !!*/);
}
