Question

是否可以使用Angular（4.3+）中的新HttpClient对POST（以及其他请求的类型）进行类型检查？官方文档（https://angular.io/guide/http#typechecking-the-response）仅提及GET请求：

interface ItemsResponse {
  results: string[];
}

...

http.get<ItemsResponse>('/api/items').subscribe(data => {
   // data is now an instance of type ItemsResponse, so you can do this:
   this.results = data.results;
});

它是否同样适用于其他类型的请求？

据我所知，确实如此。例如

interface LoginResponse {
    token: string;
}

...
this.http.post<LoginResponse>(url, body, options).subscribe(
    data => {
        this.jwtoken = data.token;
        return 'Login successful';
    },
    err => {
        console.log(err);
    }
);
