正则表达式在Golang HandleFunc函数中不起作用

Question

I am trying to redirect the URL based on a pattern in Go. If my URL is containing "clientApi" then I am sending it to clientApiPoint func otherwise I am sending it to redirectApiPoint func. My handleRequest func is

func handleRequest()  {
    r := mux.NewRouter()
    r.HandleFunc("/", homePage)
    r.HandleFunc("/clientApi", clientApiPoint)
    r.HandleFunc("/{^((?!clientApi).)*$}", redirectApiPoint)
    http.Handle("/", r)
    log.Fatal(http.ListenAndServe(":8081", nil))
} 

{^((?!clientApi).)*$} regex is working fine if my url is something like

localhost:8081/somerandonurl  (sending it to redirectApiPoint func)

but if there one or more "/" in the url, regex is not redirecting it to redirectApiPoint func.

localhost:8081/somerandonurl/somethingdifferent    (not sending it to redirectApiPoint. 404 page not found message)

Answer 1

your Regex work on "localhost:8081/somerandonurl" because of the first "/" so it matched.

you need somthing like "/(.*$)" but this will match any /blala/blala/...

you can test your regex from here: Regex
