问题描述
我们的应用程序在我们的生产和开发环境中都运行良好，但在我们的暂存环境中，我们遇到了常见错误：
Our app is working fine on both our production and development environments but on our staging environment we get the common error:
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)
根据我的理解，当您尝试时会发生此错误连接到非 https URL。
From my understanding this error occurs when you try to connect to a non https URL.
- 我们使用ngrok作为本地隧道它有一个
httpsurl并且工作正常。 - 对于制作我们也使用
https：// ourdomain。 com并且工作正常。 - 对于暂存，我们使用
https://staging.ourdomain.com并且发生错误。
- We use ngrok for our local tunnel which has a
httpsurl and works fine. - For production we also use
https://ourdomain.comand it works fine. - For staging we use
https://staging.ourdomain.comand the error occurs.
我见过许多解决方案，说明这样做：
I've seen many solutions stating to do this:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
但我的雇主反对禁止ATS只是为了上班，他也反对为我们的暂存网址添加例外的想法。
But my employer is against the idea of disabling ATS just to get staging to work, he is also against the idea of adding an exception for our staging URL.
我们的暂存网址会导致此错误的任何想法抛出或如何修复它？
Any ideas why our staging URL would be causing this error to throw or how to fix it?

推荐答案
App Transport Security是不只是HTTP与HTTPS。您需要使用正确配置的服务器+证书以避免ATS问题。来自Apple文档[1]：
App Transport Security is not just HTTP vs HTTPS. You need to be using properly configured servers+certificates to avoid an ATS issue. From the Apple docs [1]:
如果您使用的是OS X 10.11（或更高版本） ，您可以使用nscurl进行故障排除。弹出一个终端并运行它：
If you're on OS X 10.11 (or later), you can use nscurl to troubleshoot. Pop open a terminal and run this:
/usr/bin/nscurl --ats-diagnostics https://staging.ourdomain.com
