authentication - SignalR 与 Xamarin 客户端在调用 StartAsync() 方法时获得“CERTIFICATE_VERIFY_FAILED”

问题描述

从我的 Xamarin 客户端调用 SignalR StartAsync 让我感到震惊：

[ERROR] FATAL UNHANDLED EXCEPTION: System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception. ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception. ---> Mono.Btls.MonoBtlsException: Ssl error:1000007d:SSL routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED

任何人都可以帮我解决这个 CERTIFICATE_VERIFY_FAILED 吗？

这是堆栈跟踪：

解决方案

通过搜索堆栈溢出找出，这里是解决方案的链接：

使用 signalR 核心客户端忽略 SSL 错误

刚刚在我的 HubConnectionBuilder 中添加了选项，它起作用了！！

 HubConnection = new HubConnectionBuilder()
            .WithUrl($"https://10.0.2.2:5001/chatHub", (opts) =>
            {
                opts.HttpMessageHandlerFactory = (message) =>
                {
                    if (message is HttpClientHandler clientHandler)
                        // bypass SSL certificate
                        clientHandler.ServerCertificateCustomValidationCallback +=
                            (sender, certificate, chain, sslPolicyErrors) => { return true; };
                    return message;
                };
            })
            .Build();
