NSURLSession/NSURLConnection HTTP 加载在 iOS 9 上失败 [英] NSURLSession/NSURLConnection HTTP load failed on iOS 9

问题描述

尝试在 iOS9 上运行我现有的应用程序，但在使用 AFURLSessionManager 时失败.

__block NSURLSessionDataTask *task = [self.sessionManager dataTaskWithRequest:request completionHandler:^(NSURLResponse * __unused response, id responseObject, NSError *error) {如果(错误){} 别的 {}}];【任务简历】；

我收到以下错误:

Error Domain=NSURLErrorDomain Code=-999已取消.

还得到以下日志:

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

更新:我为我的解决方案添加了多个更新:

Update3:如果您尝试连接到只有 TLS 1.0 的主机 (YOURHOST.COM)

将这些添加到您应用的 Info.plist

NSAppTransportSecurity<字典><key>NSExceptionDomains</key><字典><key>YOURHOST.COM</key><字典><key>NSIncludesSubdomains</key><真/><key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key><真/><key>NSTemporaryExceptionMinimumTLSVersion</key><string>1.0</string><key>NSTemporaryExceptionRequiresForwardSecrecy</key><假/></dict></dict></dict>

Tried to run my existing app on iOS9 but getting failure while using AFURLSessionManager.

__block NSURLSessionDataTask *task = [self.sessionManager dataTaskWithRequest:request completionHandler:^(NSURLResponse * __unused response, id responseObject, NSError *error) {
    if (error) {

    } else {

    }
}];

[task resume];

I get the following error:

Error Domain=NSURLErrorDomain Code=-999 "cancelled.

Also getting following logs:

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

Update: I have added multiple updates to my solution: NSURLSession/NSURLConnection HTTP load failed on iOS 9

解决方案

Found solution:

In iOS9, ATS enforces best practices during network calls, including the use of HTTPS.

From Apple documentation:

ATS prevents accidental disclosure, provides secure default behavior, and is easy to adopt. You should adopt ATS as soon as possible, regardless of whether you’re creating a new app or updating an existing one. If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible.

In beta 1, currently there is no way to define this in info.plist. Solution is to add it manually:

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

Update1: This is a temporary workaround until you're ready to adopt iOS9 ATS support.

Update2: For more details please refer following link: http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/

Update3: If you are trying to connect to a host (YOURHOST.COM) that only has TLS 1.0

Add these to your app's Info.plist

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>YOURHOST.COM</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>1.0</string>
            <key>NSTemporaryExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>
