Soap 使用ONVIF摄像头进行身份验证时Http 400错误请求

我试图通过发送usernametoken soap请求来获得设备功能，从而通过ONVIF摄像机进行身份验证。但是我正在获取请求的操作，需要授权，并且发送者未被授权错误从相机返回。下面是我正在发送的Usernametoken：

我正在以这种方式创建：

string guid = Guid.NewGuid().ToString();
string nonce = GetSHA1String( guid );

public string GetSHA1String(string phrase)
{
        byte[] hashedDataBytes = SHA1.Create().ComputeHash(Encoding.UTF8.GetBytes(phrase)); 
        return Convert.ToBase64String(hashedDataBytes);
}

string created = System.DateTime.Now.ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ss.fffZ");

string pwd = "admin";
string hashedPassword = CreateHashedPassword(nonce, created, pwd);

 public string CreateHashedPassword(string nonce, string created, string password)
 {
       return GetSHA1String(nonce + created + password);
 }

我以以下方式创建PasswordDigest：

string guid = Guid.NewGuid().ToString();
string nonce = GetSHA1String( guid );

public string GetSHA1String(string phrase)
{
        byte[] hashedDataBytes = SHA1.Create().ComputeHash(Encoding.UTF8.GetBytes(phrase)); 
        return Convert.ToBase64String(hashedDataBytes);
}

string created = System.DateTime.Now.ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ss.fffZ");

string pwd = "admin";
string hashedPassword = CreateHashedPassword(nonce, created, pwd);

 public string CreateHashedPassword(string nonce, string created, string password)
 {
       return GetSHA1String(nonce + created + password);
 }

我不知道我做错了什么。我真的很感激有人能在这件事上帮忙

散列时，nonce+created+密码的nonce部分必须是二进制数据。有关类似问题，请参阅此线程：
