c# - Apns c#异常无法从传输连接读取数据一个现有连接被远程主机强行关闭
<p><p>我正在尝试使用有效的 p12 和 token 发送苹果推送通知,如下所示:</p>
<pre><code>void connect()
{
client = new TcpClient();
//Notify we are connecting
var eoc = this.OnConnecting;
if (eoc != null)
eoc(this.appleSettings.Host, this.appleSettings.Port);
try
{
client.Connect(this.appleSettings.Host, this.appleSettings.Port);
}
catch (Exception ex)
{
throw new ConnectionFailureException("Connection to Host Failed", ex);
}
if (appleSettings.SkipSsl)
{
networkStream = client.GetStream();
}
else
{
stream = new SslStream(client.GetStream(), false,
new RemoteCertificateValidationCallback((sender, cert, chain, sslPolicyErrors) => { return true; }),
new LocalCertificateSelectionCallback((sender, targetHost, localCerts, remoteCert, acceptableIssuers) =>
{
return certificate;
}));
try
{
stream.AuthenticateAsClient(this.appleSettings.Host, this.certificates, System.Security.Authentication.SslProtocols.Tls, false);
//stream.AuthenticateAsClient(this.appleSettings.Host);
}
catch (System.Security.Authentication.AuthenticationException ex)
{
throw new ConnectionFailureException("SSL Stream Failed to Authenticate as Client", ex);
}
if (!stream.IsMutuallyAuthenticated)
throw new ConnectionFailureException("SSL Stream Failed to Authenticate", null);
if (!stream.CanWrite)
throw new ConnectionFailureException("SSL Stream is not Writable", null);
networkStream = stream;
}
//Start reading from the stream asynchronously
Reader();
}
}
</code></pre>
<p>当我将行代码 System.Security.Authentication.SslProtocols.Tls 更改为 System.Security.Authentication.SslProtocols.Ssl3 时,我得到“身份验证失败,因为远程方已关闭传输流”</p>
<p>如何发送 APNS?
怎么发送apns???</p></p>

<p><p>由于存在重大安全漏洞,Apple(以及其他)在上个月(2014 年 10 月)内放弃了 SSL3;称为 POODLE(Padding Oracle On Downgraded Legacy Encryption)。</p></p>
