Should URLEscape convert space characters to '+' or '%20'? #502
Description
I have a small program trying to download the following file, via http.Get: http://www.sfmta.com/cms/uploadedfiles/dpt/bike/Safety/Chapter%202_General% 20Bicycle%20Rules.pdf When http.Get handles the url, the combination of http.URLUnescape (in http.ParseURL) and http.URLEscape (in req.Write) converts the url into this: http://www.sfmta.com/cms/uploadedfiles/dpt/bike/Safety/Chapter+2_General+Bi cycle+Rules.pdf However, that link returns a 404. Is there a reason why %20 is converted to '+'? Would it be safer to use %20? Relevant code is here: package main import "http" func main() { rawurl := `http://www.sfmta.com/cms/uploadedfiles/dpt/bike/Safety/Chapter%202_General %20Bicy cle%20Rules.pdf` url,err := http.ParseURL (rawurl ) if err != nil { println("error parsing", err) } println("Final url", url.String()) resp,_,err := http.Get ( rawurl ) if err != nil { println("error downlaoding", err.String()) } println(resp.StatusCode); }
