当我将Xcode更新到7.0或iOS 9.0时,我面临着这个问题。 不知何故,它开始给我标题错误

"由于应用程序传输安全问题,资源无法加载 策略要求使用安全连接"

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];

}

该服务运行良好的Xcode早期版本和iOS以前的版本,但当我更新到Xcode 7.0,在iOS 9.0上,它开始给我的问题如下,当我调用上面的web服务方法。我得到的日志错误是:

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,有任何提前的想法,我可以如何删除服务呼叫错误?

无法加载的资源为ios9 应用程序传输安全Xcode 7 beta 6 https://stackoverflow.com/a/32609970


当前回答

如果你使用firebase,它会在NSAppTransportSecurity部分中添加NSAllowsArbitraryLoadsInWebContent = true,而NSAllowsArbitraryLoads = true将不起作用

其他回答

无法加载资源,因为应用程序传输安全策略要求使用在Swift 4.03中工作的安全连接。

打开你的pList.info作为源代码,并粘贴:

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

iOS 9.0或更高版本、OS X v10.11及更高版本提供传输安全性。

默认情况下只允许在应用中调用https。要关闭应用程序传输安全,在信息中添加以下行。plist文件…

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

欲了解更多信息: https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW33

对于那些在localhost上开发的人,请遵循以下步骤:

Tap the "+" button next to Information Property List and add App Transport Security Settings and assign it a Dictionary Type Tap the "+" button next to the newly created App Transport Security Settings entry and add NSExceptionAllowsInsecureHTTPLoads of type Boolean and set its value to YES. Right click on NSExceptionAllowsInsecureHTTPLoads entry and click the "Shift Row Right" option to make it a child of the above entry. Tap the "+" button next to the NSExceptionAllowsInsecureHTTPLoads entry and add Allow Arbitrary Loads of type Boolean and set its value to YES

注意:它最终看起来应该像下图所示的那样

你只需要在你的URL中使用HTTPS而不是HTTP,它就会工作

适用于iOS 10。x和Swift 3。X[也支持以下版本]只需在'info.plist'中添加以下行

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