Question

以下代码始终返回nil。

let url = NSURL(string: "https://s3.amazonaws.com/test-contentdelivery-mobilehub-462838928/tree.jpg")
let data = NSData(contentsOfURL: url!)

2015-10-31 16:25:16.795 test2[59798:19080494] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)

网址已经https，aws s3提供TLS 1.2 SSL。您可以在浏览器中尝试上述URL，并检查认证和连接信息。看起来已经满足了ios 9的要求，但数据仍然没有。我不想在Info.plist中设置“允许任意加载”= YES。任何的想法？我错过了什么吗？是NSData（contentsOfURL：url！）使用http而不是https？

AWS在他们的博客中写道，他们尚未准备好ATS： https://mobile.awsblog.com/post/Tx2QM69ZE6BGTYX/Preparing-Your-Apps-for-iOS-9

他们建议在准备就绪之前定义退出规则：

<key>NSAppTransportSecurity</key>
<dict>
      <key>NSExceptionDomains</key>
      <dict>
            <key>amazonaws.com</key>
            <dict>
                  <key>NSThirdPartyExceptionMinimumTLSVersion</key>
                  <string>TLSv1.0</string>
                  <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                  <false/>
                  <key>NSIncludesSubdomains</key>
                  <true/>
            </dict>
            <key>amazonaws.com.cn</key>
            <dict>
                  <key>NSThirdPartyExceptionMinimumTLSVersion</key>
                  <string>TLSv1.0</string>
                  <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                  <false/>
                  <key>NSIncludesSubdomains</key>
                  <true/>
            </dict>
      </dict>
</dict>

Answer 2

直到亚马逊准备就绪，你可以将以下内容放入info.plist：

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>amazonaws.com</key>
    <dict>
      <key>NSIncludesSubdomains</key>
      <true/>
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
    </dict>
  </dict>
</dict>

ios 9 NData甚至调用https url返回nil
