Mux处理程序未收到从curl发布传递的所有查询参数

Question

I am not able to receive all the query parameters using Mux. Only the first part is received

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/resize", resizeImageFromPayload).Methods("POST")
    log.Fatal(http.ListenAndServe(":8080", router))
}

func resizeImageFromPayload(w http.ResponseWriter, r *http.Request) {
    widthParameter := r.URL.Query().Get("width")
    heightParameter := r.URL.Query().Get("height")
    fmt.Println(r.URL.String())
    fmt.Println(widthParameter)
    fmt.Println(heightParameter)
   //More code..
}

When I call the api using curl curl -XPOST http://localhost:8080/resize?width=100&height=100 -o img_resize.png -F "file=@snap1.png" This is what it prints:

/resize?width=100
100

it seems like it omitted the &height=100 part. Any idea ?

Thanks in advance.

The URL http://localhost:8080/resize?width=100&height=100 contains a special character & that has another meaning to shell.

In order to use ampersand (&) as an actual character inside the URL, you need to put the URL in quotes: "http://localhost:8080/resize?width=100&height=100"
