ios - OSX 上的 AWS MQTT

Question

在 OSX 应用程序中 here ，我可以在 iOS9 上使用 AWS MQTT，但是当我在 OSX10.11 上尝试同样的操作时，我收到此错误:

CFNetwork SSLHandshake failed (-9829)

错误-9828定义为

errSSLPeerCertUnknown = -9829, /* unknown certificate */

我的 OSX info.plist 是

<key>NSAppTransportSecurity</key>
    <dict>
            <key>NSAllowsArbitraryLoads</key>
            <true/>

为什么 OSX 失败而 iOS 成功？

Answer 1

由于 SSL 握手问题而失败。它正在检测无效证书。

报告并解决了类似问题 here ，引用相同的错误代码。由于 p12 文件中的多个身份，该问题被追溯到身份不匹配。

在那种情况下，p12 文件中有两个证书，但代码只读取第一个。

我建议转储 .p12 文件的内容，并确认证书。将它们张贴在这里进行审查。
