配置HttpClientFactory时出现证书错误

我需要在HttpClientFactory中添加证书。 使用HttpClient旧实现看起来像这样：

 var cookieContainer = new CookieContainer(); var handler = new HttpClientHandler { CookieContainer = cookieContainer }; var basePath = Directory.GetCurrentDirectory(); var certificatePath = Path.Combine(basePath, certPath); var fileExists = File.Exists(certificatePath); if (!fileExists) throw new ArgumentException(certificatePath); var certificate = new X509Certificate2(certificatePath, certPwd); handler.ClientCertificates.Add(certificate); using (var client = new HttpClient(handler)) { client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(accept)); client.DefaultRequestHeaders.Add("ApiKey", apiKey); var body = new { UserName = username, UserPassword = password }; var jsonBody = JsonConvert.SerializeObject(body); var content = new StringContent(jsonBody, Encoding.UTF8, contentType); var loginResponse = client.PostAsync(loginEndpoint, content).Result; } 

但是当我尝试从ConfigurePrimaryHttpMessageHandler获取连接时，我无法在处理程序中设置ClientCertificates 。 怎么解决这个？

UPDATE

 public void SetUpHttpClients(IServiceCollection services) { var loginEndpoint = Path.Combine(baseApi, "api/authentication); var fileExists = File.Exists(certificatePath); if (!fileExists) throw new ArgumentException(certificatePath); var certificate = new X509Certificate2(certificatePath, certPwd); services.AddHttpClient("TestClient", client => { client.BaseAddress = new Uri(baseApi); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(accept)); client.DefaultRequestHeaders.Add("ApiKey", apiKey); var body = new { Username = username, Password = password }; var jsonBody = JsonConvert.SerializeObject(body); var content = new StringContent(jsonBody, Encoding.UTF8, contentType); var loginResponse = client.PostAsync(loginEndpoint, content).Result; }).ConfigurePrimaryHttpMessageHandler(() => { var cookieContainer = new CookieContainer(); var handler = new HttpClientHandler { CookieContainer = cookieContainer }; handler.ClientCertificates.Add(certificate); return handler; });

exception消息是准确的。

致电ClientCertificates.Add(certificate); 与以前的做法没什么不同

 services.AddHttpClient("TestClient", client => { client.BaseAddress = new Uri(baseApi); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(accept)); client.DefaultRequestHeaders.Add("ApiKey", apiKey); }) .ConfigurePrimaryHttpMessageHandler(() => { var handler = new HttpClientHandler { CookieContainer = cookieContainer }; handler.ClientCertificates.Add(certificate); return handler; });
