有沒有辦法在 Go HTTP 服務(wù)器中攔截錯(cuò)誤的 HEAD 請(qǐng)求？這里的錯(cuò)誤請(qǐng)求是發(fā)送帶有 HEAD 請(qǐng)求的 JSON 有效負(fù)載。我將此稱為“錯(cuò)誤請(qǐng)求”，但是當(dāng)我嘗試通過curl 對(duì)正文發(fā)出 HEAD 請(qǐng)求時(shí)，我收到此錯(cuò)誤。但是，Go 中不會(huì)發(fā)生日志記錄。package mainimport (    "fmt"    "log"    "net/http")func handler(w http.ResponseWriter, r *http.Request) {    log.Println(r.Method, r.URL)    _, _ = fmt.Fprintf(w, "Hello")}func main() {    http.HandleFunc("/", handler)    log.Fatal(http.ListenAndServe(":8080", nil))}如果我發(fā)送不帶正文的curl 請(qǐng)求，它將按預(yù)期工作并生成日志條目2019/11/28 10:58:59 HEAD /。$ curl -v -X HEAD  http://localhost:8080curl -i -X HEAD  http://localhost:8080Warning: Setting custom HTTP method to HEAD with -X/--request may not work theWarning: way you want.
