ios - CFNetwork SSLHandshake 失败 (-9824) NSURLSession/NSURLConnection HTTP 加载失败 (kCFStreamErrorDomainSSL, -9824)

Question

我在 iOS 9 中使用以下代码向 https 服务器发送发布请求

[NSURLConnection sendSynchronousRequest:request returningResponse:&requestResponse error:&err];  

但是我得到以下错误

CFNetwork SSLHandshake failed (-9824)
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824)

我已经尝试将异常添加到 info.plist 中，如下所示:

<key>NSAppTransportSecurity</key>  
<dict>
    <key>NSExceptionDomains</key>
    <dict>
    <key>www.myserver.com</key>
    <dict>
    <key>NSIncludesSubdomains</key>
    <true/>
    <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
    <true/>
    <key>NSTemporaryExceptionMinimumTLSVersion</key>
    <string>TLSv1.1</string>
</dict>

我也试过

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

它可以在真实设备上运行，但不能在模拟器上运行

1. From NSURLConnection to NSURLSession worked for me

我能够解决如下问题(不推荐使用 NSURLConnection，您需要使用 NSURLSession):

NSURL *URL = [NSURL URLWithString:@"http://example.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

[NSURLConnection sendAsynchronousRequest:request
                                queue:[NSOperationQueue mainQueue]
                    completionHandler:^(NSURLResponse *response, NSData  *data, NSError *error) {
 // ... 
}];

转换为:

NSURL *URL = [NSURL URLWithString:@"http://example.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request
                                     completionHandler:
 ^(NSData *data, NSURLResponse *response, NSError *error) {
     // ...
  }];

[task resume];

From NSURLConnection to NSURLSession

1. 也包含在 Info.plist 中，请参阅文档:

Info.plist reference

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
  <key>yourdomain.net</key>
  <dict>
  <key>NSIncludesSubdomains</key>
  <true/>
  <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
  <true/>
  <key>NSTemporaryExceptionMinimumTLSVersion</key>
  <string>1.2</string>
  <key>NSTemporaryExceptionRequiresForwardSecrecy</key>
  <false/>
  </dict>
  </dict>
</dict>

只需从 api.amazon.com 更改为 yourdomain.net

希望对您有所帮助。
