將「net/http」上的*請求傳遞到函數Golang

Question

是否可以將請求值傳遞給另一個函數？

import "net/http" 

func main() { 
    http.HandleFunc("saySomething", Say) 
} 

func Say(responseW http.ResponseWriter, request *http.Request) { 
    name := getName(request) // passing request value to another function 
} 

func getName(request someType) string { 
    request.ParseForm() 
    return request.Form.Get("name") 
} 

Answer 1

是的，你可以'因爲request是一個常規變量。 它通過指針傳遞，所以如果您將更改request在getName它也將在Say更改。

package main 

import "net/http" 

func main() { 
    http.HandleFunc("saySomething", Say) 
} 

func Say(responseW http.ResponseWriter, request *http.Request) { 
    name := getName(request) // passing request value to another function 
    println(name) 
} 

func getName(request *http.Request) string { 
    request.ParseForm() 
    return request.Form.Get("name") 
}
