我無法弄清楚如何編輯此 Radius MSCHAPv2 示例并從 radius 客戶端獲取密碼。我正在使用的 go 庫是https://github.com/layeh/radius。MSCHAPv2 是否發送帶有密碼的用戶名？如何從客戶端獲取密碼到服務器？package microsoftimport (    "log"    "reflect"    "layeh.com/radius"    "layeh.com/radius/rfc2759"    "layeh.com/radius/rfc2865"    "layeh.com/radius/rfc2868"    "layeh.com/radius/rfc2869"    "layeh.com/radius/rfc3079")const (    radiusSecret = "secret")func RunRadiusServer() {    handler := func(w radius.ResponseWriter, r *radius.Request) {        username := rfc2865.UserName_GetString(r.Packet)        challenge := MSCHAPChallenge_Get(r.Packet)        response := MSCHAP2Response_Get(r.Packet)        // TODO: look up user in local database.        // The password must be stored in the clear for CHAP mechanisms to work.        // In theory, it would be possible to use a password hashed with MD4 as        // all the functions in MSCHAPv2 use the MD4 hash of the password anyway,        // but given that MD4 is so vulerable that breaking a hash is almost as        // fast as computing it, it's just not worth it.        password := "password-from-database"        if len(challenge) == 16 && len(response) == 50 {            // See rfc2548 - 2.3.2. MS-CHAP2-Response            ident := response[0]            peerChallenge := response[2:18]            peerResponse := response[26:50]            ntResponse, err := rfc2759.GenerateNTResponse(challenge, peerChallenge, username, password)            if err != nil {                log.Printf("Cannot generate ntResponse for %s: %v", username, err)                w.Write(r.Response(radius.CodeAccessReject))                return            }我編輯了函數的頂部：username := rfc2865.UserName_GetString(r.Packet)password := rfc2865.UserPassword_GetString(r.Packet)log.Printf("bytes %+v", r.Get(1), string(r.Get(1)))log.Printf("bytes %+v", r.Get(2), string(r.Get(2)))log.Printf("u/p %v, %v\n", username, password)用戶名正確。密碼為空。1 是用戶名。我無法對 2 進行排序，因為它不會將字節轉換為字符串。這里有一個類似但不是 Go 特定的問題，也沒有正確回答。謝謝！
