Summarize the problem

I wanna sending a HTTP GET requset within @Angular/common/HttpClint.

But there is no resopnse, even , chrome network sniffer cannot detect any network activities.

And when tried to console.log :

 console.log(this.http.get("http://localhost/users"));

Then I found that the result of console was:

And chrome network sniffer didn't detect any XHR related to my action.

Why?

Can it because of using @ng-cli to create this project?

I init this Angular project via @ng-cli

when I using an exaple project(Hreos Example) download from www.angular.cn/generated/z…. There are no problems.

But each of my project that created by @ng-cil(ng new project) occours that problem
