HTTP requests using the browser console

HTTP requests using the browser console

I want to test a download link from the broswer console by using HTTP
requests:
So when doing this, the console tells me:
get http://wallbase.cc/wallpaper/3023660;
SyntaxError: Unexpected identifier
get "http://wallbase.cc/wallpaper/3023660";
SyntaxError: Unexpected string
So how do you actually make HTTP calls from the console and viewing the
response?
Thanks
