FireBase错误-9806,SSL错误-1200

Question

我正在使用2016年I/O中引入的新FireBase SDK,并且在与我的应用程序集成后出现此错误.这在应用程序启动时发生.

Answer 1

问题出在网络上。有时网络状况太慢，导致网络超时，无法按时进行 SSL 检查。这在需要更好安全性的 iOS 9.x 上也更常见。您在哪种 iOS 版本和哪个设备上运行它？一开始就一直这样吗？

Answer 2

这是由iOS 9+上的App Transport Security引起的.Apple对所有服务器都不满足的SSL证书施加了限制.

如果您拥有生成此消息的服务器,我建议您更新到更安全,更现代的SSL服务器证书.但由于它是Google/Firebase的服务器,我们所能做的就是专门为此域禁用App Transport Security.

以下是列出域名的部分:

NSErrorFailingURLStringKey=https://app-measurement.com...

您需要将此域添加到Info.plist文件中,如下所示:

<key>NSExceptionDomains</key>
<dict>
    <!-- Firebase/Google Analytics server - Disables App Transport Security for this specific domain -->
    <key>app-measurement.com</key>
    <dict>
        <key>NSExceptionAllowsInsecureHTTPLoads</key>
        <true/>
    </dict>
</dict>

请记住,允许来自第三方服务器的不安全连接可能会为您的应用带来安全漏洞.但是,如果你不发送任何敏感数据分析服务器(你不应该这样做无论如何),然后曝光应该是最小的.

根据Apple的ATS文档,包括任何ATS例外将在您下次提交到App Store时触发审核,因此您可能也想考虑这一点.
