swift – NSURLSession / NSURLConnection HTTP加载失败(kCFStreamErrorDomainSSL,-9802)（nsurlerror错误怎么办）
我收到错误：NSURLSession / NSURLConnection HTTP加载失败(kcfStreamErrorDomainSSL,-9802),我怀疑这是因为查询来自Parse的图像.这是我查询的方法：
func fetchImageForEmployee(employee: PFEmployee,completion: (error: String?,image: UIImage?) -> Void) {
if (employee.profilePicture == nil) {
completion(error: "No image file",image: nil)
} else {
employee.profilePicture!.getDataInBackgroundWithBlock({ (data,error) -> Void in
if let error = error {
let errorString = error.userInfo["error"] as? String
completion(error: errorString,image: nil)
} else if (data != nil) {
let image = UIImage(data: data!)
completion(error: nil,image: image)
} else {
completion(error: nil,image: nil)
}
})
}
}
我还打印了错误,这是调试器中出现的内容：不允许在取消分配时尝试加载视图控制器的视图,并且可能导致未定义的行为(UISearchController：0x13ee44dc0)
我不知道出了什么问题,所以所有答案都值得赞赏.
右键单击Info.plist文件>打开作为>源代码,并在最新的< / dict>之前添加以下内容：
<key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict>
在iOS9中,ATS在网络呼叫期间实施最佳实践,包括使用HTTPS.在Apple Documentation中了解更多相关信息.
(kCFStreamErrorDomainSSL, -9802) 错误解决
只能再找方法试试了，找到了这个：修改 (...)/platforms/ios/嘎嚓嘎嚓/Classes/AppDelegate.m 文件，添加以下代码：
@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
return YES;
}
@end哈哈。。。果然有用，简直 Nice!
不过，info.list 文件是之前修改过的，然后就觉得是不是只需要修改 AppDelegate.m 文件就可以呢？
经过验证是不行的，必须同时修改 info.list 和 AppDelegate.m 文件才可以解决此问题。
info.list 添加第一种代码即可：
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
iOS 9中的HTTPS请求：NSURLSession / NSURLConnection HTTP加载失败(kCFStreamErrorDomainSSL,-9802)
我正在更新我的应用程序以适应苹果的新
ATS.没有对Plist-Info的任何更改,以下代码在vanilla iOS 9模拟器中的sendSynchronousRequest()中引发错误.
NSURL *url =[NSURL URLWithString:@"https://Google.com"];
NSMutableuRLRequest *request = [[NSMutableuRLRequest alloc]init];
[request setHTTPMethod:@"GET"];
[request setURL:url];
NSURLResponse *urlResponse = nil;
NSError *error = nil;
NSData *reponse = [NSURLConnection sendSynchronousRequest:request
returningResponse:&urlResponse
error:&error];
错误：
NSURLSession / NSURLConnection HTTP加载失败(kcfStreamErrorDomainSSL,-9802)
对这个问题可能背后有什么想法？
Ps：据了解,NSURLConnection已被弃用.但是,如果我在Plist中添加了AllowArbitraryLoads,那么这个调用可以找到.
解决方法
NSURLSession / NSURLConnection HTTP加载失败(kcfStreamErrorDomainSSL,-9802)
对应于服务器不支持“Forward Secrecy”.
对应于服务器不支持“Forward Secrecy”.
要解决此问题,请将域异常添加到.plist文件中,如下所示：
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>test.testdomain.com</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NstemporaryExceptionRequiresForwardSecrecy</key>
<false/>
</dict>

我们的应用程序具有 pdf 和音频文件的下载功能。我在后台模式下添加了下载功能，但是应用程序有时会崩溃并且无法重现该步骤。这是 Firebase 崩溃报告。

我在 AppDelegate.swift 中添加了后台会话处理程序。
//MARK: background session handling
func application(_ application: UIApplication,handleEventsForBackgroundURLSession identifier: String,completionHandler: @escaping () -> Void) {
print("-- handleEventsForBackgroundURLSession --")
let backgroundConfiguration = URLSessionConfiguration.background(withIdentifier: identifier)
let backgroundSession = URLSession(configuration: backgroundConfiguration,delegate: DownloadSessionDelegate.sharedInstance,delegateQueue: nil)
print("Rejoining session \\(backgroundSession)")
DownloadSessionDelegate.sharedInstance.addCompletionHandler(completionHandler,identifier: identifier)
}
这里是 DownloadSessionDelegate.swift 中的完成处理程序。我不确定是什么问题。
//MARK: completion handler
func addCompletionHandler(_ handler: @escaping CompleteHandlerBlock,identifier: String) {
if identifier.isEmpty { return }
dispatchQueue.global().async {
self.handlerQueue[identifier] = handler
}
}

我已验证 discussionViewController.fetchPostData() 不会强制解开任何可选选项，没有 try! 并且在任何地方都使用 [weak self] 和 self?。该函数非常大，所以我很难缩小崩溃发生的范围。
