我意识到这个问题涉及旧技术。我正在调用供应商系统，无法更改服务。我们需要调用XML / SOAP WS，然后对请求进行签名。 10年前，我会使用像Web Services Enhancements（WSE）3.0这样的东西，然后继续前进。就像今天一样，我仍然坚持在.Net Core（.Net Standard 2.0）应用程序中做什么。
我愿意使用多种解决方案，包括商业解决方案。我看着奇尔卡特，但似乎我们放弃了太多而无法使用它。
然而，他们确实有一个很好的例子。
请求如下：

我通过滚动我们自己的肥皂信封，签署它们并在HttpClient上铺设它来解决这个问题。 .NET Core中的WCF无法为我们获得与我们的第三方服务的各种怪癖有关的结果。
这里是代码，它应该很容易改变你的要求：
// ...
private static HttpClient Client = new HttpClient(); // https://aspnetmonsters.com/2016/08/2016-08-27-httpclientwrong/
// ...
Uri uri = new Uri("https://thirdparty.com/service.svc");
X509Certificate2 cert = // from some store etc
var envelope = BuildEnvelope(cert);
using (HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, uri))
{
request.Content = new StringContent(envelope, Encoding.UTF8, "application/soap+xml");
using (HttpResponseMessage response = Client.SendAsync(request).Result)
{
if (response.IsSuccessStatusCode)
{
response.Content.ReadAsStringAsync().ContinueWith(task =>
{
string thirdparty_envelope = task.Result;
XElement thirdparty_root = XElement.Parse(thirdparty_envelope);
// etc
}, TaskContinuationOptions.ExecuteSynchronously);
}
}
}
private string BuildEnvelope(X509Certificate2 certificate)
{
string envelope = null;
// note - lots of bits here specific to my thirdparty
string cert_id = string.Format("uuid-{0}-1", Guid.NewGuid().ToString());
using (var stream = new MemoryStream())
{
Encoding utf8 = new UTF8Encoding(false); // omit BOM
using (var writer = new XmlTextWriter(stream, utf8))
{
// timestamp
DateTime dt = DateTime.UtcNow;
string now = dt.ToString("o").Substring(0, 23) + "Z";
string plus5 = dt.AddMinutes(5).ToString("o").Substring(0, 23) + "Z";
// soap envelope
// <s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
