将observable <object>转换为observable <task []>

Question

return  this.http.get('http://localhost:3000/tasks');

//Returns Observable<Object>, but I want it to return or convert into Observable<Task[]>.

Task只是一个与/ tasks端点匹配JSON对象的接口。

假设您正在使用HttpClient：

return this.http.get<Task[]>('http://localhost:3000/tasks');
