ios - 无法加载资源，因为 App Transport Security 策略要求使用安全连接

Question

当我将 Xcode 更新到 7.0 或 iOS 9.0 时，我遇到了问题。不知何故，它开始给我标题错误

"The resource could not be loaded because the App Transport Security policy requires the use of a secure connection"

网络服务方法:

-(void)ServiceCall:(NSString*)ServiceName :(NSString *)DataString
{
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
    [sessionConfiguration setAllowsCellularAccess:YES];
    [sessionConfiguration setHTTPAdditionalHeaders:@{ @"Accept" : @"application/json" }];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",ServiceURL]];
    NSLog(@"URl %@%@",url,DataString);
    // Configure the Request
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setValue:[NSString stringWithFormat:@"%@=%@", strSessName, strSessVal] forHTTPHeaderField:@"Cookie"];
    request.HTTPBody = [DataString dataUsingEncoding:NSUTF8StringEncoding];
    request.HTTPMethod = @"Post";

    // post the request and handle response
    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
                                          {
                                              // Handle the Response
                                              if(error)
                                              {
                                                  NSLog(@"%@",[NSString stringWithFormat:@"Connection failed: %@", [error description]]);

                                                  // Update the View
                                                  dispatch_async(dispatch_get_main_queue(), ^{

                                                      // Hide the Loader
                                                      [MBProgressHUD hideHUDForView:[[UIApplication sharedApplication] delegate].window animated:YES];


                                                  });
                                                  return;
                                              }
                                              NSArray * cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:request.URL];
                                              for (NSHTTPCookie * cookie in cookies)
                                              {
                                                  NSLog(@"%@=%@", cookie.name, cookie.value);
                                                  strSessName=cookie.name;
                                                  strSessVal=cookie.value;

                                              }

                                              NSString *retVal = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
}];
[postDataTask resume];

}

该服务在 Xcode 早期版本和 iOS 早期版本上运行良好但是当我更新到 iOS 9.0 上的 Xcode 7.0 时，当我调用上述 Web 服务方法时，它开始出现如下问题。我得到的记录错误是:

Connection failed: Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSUnderlyingError=0x7fada0f31880 {Error Domain=kCFErrorDomainCFNetwork Code=-1022 "(null)"}, NSErrorFailingURLStringKey=MyServiceURL, NSErrorFailingURLKey=MyServiceURL, NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.}

我已经尝试了以下问题和答案，但没有得到任何结果，是否有任何先进的想法可以消除该服务调用错误？

1. The resource could not be loaded is ios9
2. App Transport Security Xcode 7 beta 6

Answer 1

我已经通过在 info.plist 中添加一些键来解决它。我遵循的步骤是:

1. 打开我的项目目标的 info.plist 文件

2. 添加了一个名为 NSAppTransportSecurity 的 Key 作为 Dictionary。

3. 添加一个名为 NSAllowsArbitraryLoads 的子项作为 Boolean 并将其值设置为 YES，如下图所示。

清理项目，现在一切都像以前一样正常运行。

编辑:或者在 info.plist 文件的源代码中，我们可以添加:

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>
        <dict>
            <key>yourdomain.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
       </dict>
  </dict>
