使用.Net HttpClient绕过证书

我正在尝试将REST消息发布到存在证书问题的网站。在我们的IT人员解决该问题之前，我需要在执行PostAsync呼叫时绕过此操作。

由于某种原因，ServerCertificateCustomValidationCallback它不再是的一部分HttpClientHandler。还有另一种方法可以解决此问题以避免权限错误？谢谢。

这是我在做什么的示例。

string json = JsonConvert.SerializeObject(new
            {
                Message = new
                {
                    TestID = "1",
                }
            });


var spHandler = new HttpClientHandler()
{
    ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) =>
    {
        return true;
    }
};

System.Net.Http.HttpClient client = new System.Net.Http.HttpClient(spHandler,true);
client.BaseAddress = new System.Uri("https://test.com");
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
var content = new StringContent(json, Encoding.UTF8, "application/json");
HttpResponseMessage msg = client.PostAsync(@"/Test", content).Result;

编辑：（修复了“ /”定界符问题）

从

 client.BaseAddress = new System.Uri("https://test.com");
 HttpResponseMessage msg = client.PostAsync(@"/Test", content).Result;

至

 client.BaseAddress = new System.Uri("https://test.com/");
 HttpResponseMessage msg = client.PostAsync("Test", content).Result;
