谢谢大家通过搜索堆栈溢出找到答案，以下是解决方案的链接： 刚刚在我的HubConnectionBuilder中添加了一些选项，效果很好
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();

无法建立SSL连接-您的服务器设置是否具有SSL证书？Hello@Jason I我的服务器我刚刚安装了signalR nugget软件包，添加到Startup services.signalR和路由，并添加了一个集线器类，如教程中所示。所以回答你的问题，我想我没有ssl证书，但我不确定。你能告诉我在哪里可以看到我有一个吗？开始时，我必须添加一个自签名证书，以便从浏览器调用我的服务器，但这是一个不同的证书，对吗？注意。无法建立SSL连接-您的服务器设置是否具有SSL证书？Hello@Jason I我的服务器我刚刚安装了signalR nugget软件包，添加到Startup services.signalR和路由，并添加了一个集线器类，如教程中所示。所以回答你的问题，我想我没有ssl证书，但我不确定。你能告诉我在哪里可以看到我有一个吗？开始时，我必须添加一个自签名证书，以便从浏览器调用我的服务器，但这是一个不同的证书，对吗？谢谢分享。别忘了接受答案。@WendyZang MSFT如果对你有帮助，请你投票好吗？谢谢分享。别忘了接受答案。@WendyZang MSFT如果对你有帮助，请你投票好吗？非常感谢。
