As Didier says, it's your browser trying to load the favicon. You can prevent this by adding this code to the <head>:
<link rel="icon" type="image/png" href="data:image/png;base64,iVBORw0KGgo=">讨论(0) -
Just log the requests. You will realize that your browser also requests /favicon.ico.
See https://en.wikipedia.org/wiki/Favicon for more information.

If you request from a service is fine, but if you test from a browser and is not the production intention you can do this in golang code for avoid browser load the favicon:
http.HandleFunc("/favicon.ico", doNothing)And the function
func doNothing(w http.ResponseWriter, r *http.Request){}For people voting negatives: this works, sorry for handle it with this code in an api that doesn't need favicon or whatever...
