我不知道如何使用所需的參數(shù)發(fā)出“訪問”、“時鐘”和“審核”的請求。您能否指導我如何提出這些請求？package mainimport ( "crypto/sha256" "crypto/subtle" "encoding/base64" "encoding/json" "fmt" "log" "net/http" "os" "sync" "time")const secret = "galumphing"// Required parameters for the requesttype params struct { Act string Nonce string Signature string Timeout int64 Offset int}var ( auditLock sync.Mutex auditBase int auditLog []string)var ( seenLock sync.Mutex seenMap = map[string]bool{})var ( clockAsk = make(chan bool) clockTime = make(chan int64, 1))func main() { // Endpoints available http.HandleFunc("/903/access", handleAccess) http.HandleFunc("/903/clock", handleClock) http.HandleFunc("/903/audit", handleAudit) err := http.ListenAndServe(os.Args[1], nil) if err != nil { log.Fatal(err) }}func checkCapacity(w http.ResponseWriter) (ok bool) { auditLock.Lock() defer auditLock.Unlock() if len(auditLog) > 10 { w.WriteHeader(http.StatusServiceUnavailable) return } ok = true return}func audit(r *http.Request, params params, ok bool) { auditLock.Lock() defer auditLock.Unlock() auditLog = append(auditLog, fmt.Sprintf("%v %q %q", ok, r.URL.Path, params.Act))}func parse(w http.ResponseWriter, r *http.Request) (params params, ok bool) { defer func() { if !ok { audit(r, params, false) } }() w.Header().Set("Access-Control-Allow-Methods", "POST, OPTIONS") w.Header().Set("Access-Control-Allow-Origin", "*") w.Header().Set("Access-Control-Max-Age", "3600") if r.Method != "POST" { w.Header().Set("Allow", "POST, OPTIONS") if r.Method == "OPTIONS" { w.WriteHeader(http.StatusOK) } else { w.WriteHeader(http.StatusMethodNotAllowed) } return }

有幾種方法可以解決這個問題。您可以使用 Postman 等工具，或者只是curl從命令行使用將發(fā)布請求發(fā)送到您的端點。這是我用來訪問端點的curl命令（我使用端口8080進行測試），標志后面的位-d是請求正文：
curl -X POST http://localhost:8080/903/access -d '{"Act": "act", "Nonce": "nonce", "Signature": "signature", "TimeOut": 64, "Offset": 0}'
我確實修改了代碼以刪除大部分邏輯。此請求僅顯示當前代碼如何解析請求正文的示例。如果您對處理程序函數(shù)中的其他一些邏輯如何工作更感興趣，請告訴我，我可以編輯我的回復。這是我用于測試的代碼：
package main
import (
"encoding/json"
"fmt"
"log"
"net/http"
"os"
)
// Required parameters for the request
type params struct {
Act string
Nonce string
Signature string
Timeout int64
Offset int
}
func main() {
// Endpoints available
http.HandleFunc("/903/access", handleAccess)
err := http.ListenAndServe(os.Args[1], nil)
if err != nil {
log.Fatal(err)
}
}
func parse(w http.ResponseWriter, r *http.Request) (params params, ok bool) {
w.Header().Set("Access-Control-Allow-Methods", "POST, OPTIONS")
w.Header().Set("Access-Control-Allow-Origin", "*")
w.Header().Set("Access-Control-Max-Age", "3600")
if r.Method != "POST" {
w.Header().Set("Allow", "POST, OPTIONS")
if r.Method == "OPTIONS" {
w.WriteHeader(http.StatusOK)
} else {
w.WriteHeader(http.StatusMethodNotAllowed)
}
return
}
err := json.NewDecoder(r.Body).Decode(¶ms)
if err != nil {
w.WriteHeader(http.StatusBadRequest)
log.Printf("%s: %v", r.URL.Path, err)
return
}
return
}
func handleAccess(w http.ResponseWriter, r *http.Request) {
params, _ := parse(w, r)
fmt.Printf("%+v\n", params)
}
這是我在完成所有操作后收到的輸出：
{Act:act Nonce:nonce Signature:signature Timeout:64 Offset:0}
