问题描述
当我发布请求时，Angular 2 http没有发送该请求
When I make a post request the angular 2 http is not sending this request
this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions())
http帖子不会发送到服务器，但是如果我发出这样的请求
the http post is not sent to the server but if I make the request like this
this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions()).subscribe(r=>{});
这是有意的吗?如果可以，有人可以解释一下我为什么吗?还是一个错误?
Is this intended and if it is can someone explain me why ? Or it is a bug ?
推荐答案
由于Http类的post方法返回一个Observable，因此您需要订阅它才能执行其初始化处理.可观察者是懒惰的.
Since the post method of the Http class returns an observable you need to subscribe it to execute its initialization processing. Observables are lazy.
