gateway.sandbox.push.apple.com
成功设置并测试了APNS消息。当我切换到发布证书和gateway.push.apple.com
后,消息无法传递,并且我得到了以下异常信息:无法将数据写入传输连接:由于主机计算机中的软件中止了一个已建立的连接。
我已经按照这些教程生成了p12证书: http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1 http://code.google.com/p/apns-sharp/wiki/HowToCreatePKCS12Certificate 我正在使用SslStream
和X509Certificate2
类的.NET应用程序作为发送通知的服务器软件。以下是连接代码:
