Angular2中的http.get（）函数在哪里定义？

Question

I'm new to Typescript and Angular 2.

I wanted to look at the exact implementation of http.get() , so I opened the file in ./node_modules/angular2/src/http/http.d.ts and scrolled to the get function. This is what I found:

    /**
     * Performs a request with `get` http method.
     */
    get(url: string, options?: RequestOptionsArgs): Observable<Response>;
    /**
     * Performs a request with `post` http method.
     */
    post(url: string, body: string, options?: RequestOptionsArgs): Observable<Response>;
    /**
....

Basically, there is no function definition. It seems like an abstract method (in Java lingo). I looked through the other http files, used VSCode intellisense, and couldn't find the code for the body of the function.

Where is it and how can I find it?

It is defined here: https://github.com/angular/angular/blob/master/modules/angular2/src/http/http.ts

What you are seeing is the TypeScript typings file. It contains the definitions, but not the implementation.
