如何更改 wcf 客户端中的时间戳安全标头？

我正在尝试修改安全标头的默认过期时间，即 5 分钟到 1 分钟。 服务器的安全策略之一是时间戳（请求的日期），生存时间为一分钟。

任何想法？

我尝试创建自定义绑定但没有成功。

<s:Envelope xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\" xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">
    <s:Header>
        <o:Security s:mustUnderstand=\"1\" xmlns:o=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\">
            <u:Timestamp u:Id=\"uuid-6f772493-4b86-4695-b415-316a916119ec-2\">
                <u:Created>2019-05-23T12:14:26.920Z</u:Created>
                **<u:Expires>2019-05-23T12:19:26.920Z</u:Expires>**
            </u:Timestamp>

这就是我们需要的：

<s:Envelope xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\" xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">
    <s:Header>
        <o:Security s:mustUnderstand=\"1\" xmlns:o=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\">
            <u:Timestamp u:Id=\"uuid-6f772493-4b86-4695-b415-316a916119ec-2\">
                <u:Created>2019-05-23T12:14:26.920Z</u:Created>
                **<u:Expires>2019-05-23T12:15:26.920Z</u:Expires>**
            </u:Timestamp>

解决方案是创建自定义绑定：

protected override SecurityBindingElement CreateMessageSecurity()
{
     SecurityBindingElement security;
     security.EnableUnsecuredResponse = true;
     security.IncludeTimestamp = true;
     security.LocalClientSettings.TimestampValidityDuration = TimeSpan.FromMinutes(1);
     security.SecurityHeaderLayout = SecurityHeaderLayout.Lax;
     security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256;
     return security;          
}
