概述
调用 net/url 包即可。
例子
结构 URL
package mainimport ( "fmt" "net/url")func main() { u := url.URL{} u.Scheme = "https" u.Host = "go.dev" u.Path = "/learn/doc" values := u.Query() values.Add("hello", "world") u.RawQuery = values.Encode() fmt.Printf("URL = %s\n", u.String())}// $ go run main.go// 输入如下/** URL = https://go.dev/learn/doc?hello=world*/解析 URL
package mainimport ( "fmt" "net/url")func main() { s := "https://golang.org" u, err := url.Parse(s) if err != nil { panic(err) } fmt.Println(u.Scheme) fmt.Println(u.Host)}// $ go run main.go// 输入如下/** https golang.org*/解析 URL (带参数)
package mainimport ( "fmt" "net/url")func main() { s := "https://go.dev/learn/doc?hello=world" u, err := url.Parse(s) if err != nil { panic(err) } fmt.Println(u.Scheme) fmt.Println(u.Host) fmt.Println(u.Path) fmt.Printf("Param hello = %s\n", u.Query().Get("hello"))}// $ go run main.go// 输入如下/** https go.dev /learn/doc Param hello = world*/
