java - Apple 收据验证时的连接重置 (Java 8)
<p><p>我正在使用 Java 服务器验证 Apple 付款收据及其 <a href="https://buy.itunes.apple.com/verifyReceipt" rel="noreferrer noopener nofollow">validation server</a>。 .对于有效收据，我们大约 50% 的请求失败并出现“SocketException:连接重置”(稍后重试成功)。</p>
<p>我在部署在 Java 7 上的另一台服务器上没有遇到这种行为，但在部署到 Java 8 时开始遇到这种情况。</p>
<p>我看到 Java 8 中的默认 TLS 协议(protocol)从 TLSv1 更改为 TLSv1.2，因此我尝试将默认协议(protocol)更改为使用 Java 7 的默认值，但没有看到任何改进。这是我使用的 JVM 属性:</p>
<pre><code>-Djdk.tls.client.protocols="TLSv1,TLSv1.2,TLSv1.1"
</code></pre>
<p>知道为什么我在大约一半的时间内收到错误“SocketException:连接重置”吗？</p>
<p>谢谢!</p>

<p>任何帮助将不胜感激!</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我们目前遇到了同样的问题。如果我们从服务器调用此命令大约 5-10 次:</p>
<pre><code>openssl s_client -connect buy.itunes.apple.com:443 -tls1_2
</code></pre>
<p>它最终会挂起而没有任何响应。并且推测 java <em>SocketException</em> (我们也在日志中看到)正在发生，因为它达到了超时。 Apple 的验证服务器之一可能有问题？</p></p>
