客户端证书代码在.net 8 中不起作用

Question

我遇到了一个问题，即在调用 Azure APIM 时需要包含客户端证书。使用 Postman 或用 .NET Framework 4.8 编写的 C# 代码时，一切正常。但是，当尝试在 .NET 8.0 中执行相同的代码时，它无法工作。

有人知道为什么我无法使用客户端证书成功发送请求吗？

以下是参考代码片段。

 var cert = new X509Certificate2("D:\\MyFolder\\MyCertificate.pfx", "certificatepassword");
 var handler = new HttpClientHandler();
 handler.ClientCertificates.Add(cert);
 handler.SslProtocols = SslProtocols.Tls12;
 var client = new HttpClient(handler);
 var request = new HttpRequestMessage(HttpMethod.Post, "https://APIMURL.com");
 request.Headers.Add("Ocp-Apim-Subscription-Key", "key");
 var content = new StringContent("{\"action\":\"myaction\"}", null, "text/plain");
 request.Content = content;
 var response = await client.SendAsync(request);
 response.EnsureSuccessStatusCode();
 Console.WriteLine(await response.Content.ReadAsStringAsync());

你的代码在 .NET8 中确实对我有用。

using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;

var cert = new X509Certificate2("C:\\Users\\Downloads\\afreen12-MyCertificate-20240426.pfx", {certificatePassword});
var handler = new HttpClientHandler();
handler.ClientCertificates.Add(cert);
handler.SslProtocols = SslProtocols.Tls12;
var client = new HttpClient(handler);
var request = new HttpRequestMessage(HttpMethod.Post, "https://{apim_Name}.azure-api.net/echo/resource");
request.Headers.Add("Ocp-Apim-Subscription-Key", "02ca*********7753");
var content = new StringContent("{\"vehicleType\": \"train\",\"maxSpeed\": 125,\"avgSpeed\": 90,\"speedUnit\": \"mph\"}", null, "text/plain");
request.Content = content;
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

.csproj-

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

</Project>

我能够得到预期的输出。

请检查您是否使用了正确的凭据，例如证书密码、Ocp-Apim-Subscription-Key。
