如何从http.Response获取状态文本？

import (
    "fmt"
    "net/http"
    "strings"
)

func main() {
    resp, err := http.Get("https://www.example.com")
    if err != nil {
        fmt.Println("请求失败:", err)
        return
    }
    defer resp.Body.Close()

    statusText := getStatusText(resp)
    fmt.Println("状态文本:", statusText)
}

func getStatusText(resp *http.Response) string {
    statusParts := strings.SplitN(resp.Status, " ", 2)
    if len(statusParts) > 1 {
        return statusParts[1]
    }
    return ""
}
