C# 依赖注入配置全局 HttpClient 行为

代码示例如下：

            System.Net.ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
            services.ConfigureAll<HttpClientFactoryOptions>(options =>
            {
                options.HttpMessageHandlerBuilderActions.Add(builder =>
                {
                    builder.PrimaryHandler = new HttpClientHandler
                    {
                        ClientCertificateOptions = ClientCertificateOption.Manual,
                        ServerCertificateCustomValidationCallback = (httpRequestMessage, cert, cetChain, policyErrors) => true
                    };
                });
            });
