Passing *Request on "net/http" to function Golang
问题
能否将请求值传递给另一个函数？
import "net/http"
func main() {
http.HandleFunc("saySomething", Say)
}
func Say(responseW http.ResponseWriter, request *http.Request) {
name := getName(request) // 将请求值传递给另一个函数
}
func getName(request someType) string {
request.ParseForm()
return request.Form.Get("name")
}

Is it possible to pass Request value to another function?
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")
}

是的，你可以这样做，因为request是一个普通变量。
它是通过指针传递的，所以如果你在getName函数中改变了request，它也会在Say函数中改变。
package main
import "net/http"
func main() {
http.HandleFunc("saySomething", Say)
}
func Say(responseW http.ResponseWriter, request *http.Request) {
name := getName(request) // 将 request 的值传递给另一个函数
println(name)
}
func getName(request *http.Request) string {
request.ParseForm()
return request.Form.Get("name")
}
请参考 Golang 教程 https://tour.golang.org/moretypes/1
英文:
Yes, you can 'cause request is a regular variable.
It's passed by pointer, so if you will change request in getName it will change in Say too.
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")
}
