我有来自imgur和HTTPS的多个链接(例如https://i.imgur.com/DMKPbRe.jpg)。我将此作为我的原型应用程序的背景之一,但是每当我在iPhone 7物理设备上运行该应用程序时,该应用程序都会崩溃,错误代码为1200。实际错误如下:
2019-01-22 19:36:54.402391+0800 App[00000:0000000] Task <00000000000000000000>.<2> load failed with error Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made." UserInfo={NSErrorFailingURLStringKey=https://i.imgur.com/DMKPbRe.jpg, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _kCFStreamErrorDomainKey=3, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <00000000000000000>.<2>, _NSURLErrorRelatedURLSessionTaskErrorKey=(

用于检索网址的代码:
let imgURL = URL(string: "https://i.imgur.com/DMKPbRe.jpg")
let imgImageView = UIImageView()
imgImageView.kf.setImage(with: imgURL) { (img, err, cacheType, url) in
if img == nil {
// TODO: add placeholder image when url didn't loaded
}
let imgTexture = SKTexture(image: img!)
self.img = SKSpriteNode(texture: imgTexture)
}
我不想关闭App Transport Security,因为我不想破坏苹果使用Xcode开发的应用程序的安全性
答案 0 :(得分:2)
我在另一台服务器上发现了类似的问题,并且按照我在nscurl
中发现的@Mats的建议/评论,该服务器不支持TLS 1.3,并且反复试验还不支持NSExceptionRequiresForwardSecrecy。因此,我在项目Info.plist中添加了以下内容:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>rovicorp.com</key>
<dict>
<!-- Allow subdomains -->
<key>NSIncludesSubdomains</key>
<true/>
<!-- Exclude HTTP requests -->
<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
<false/>
<!-- Disable some extra cypher suites -->
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<!-- Specify minimum TLS version -->
<key>NSTemporaryExceptionMinimumTLSVersion</key>
<string>TLSv1.2</string>
</dict>
</dict>
</dict>
请特别注意<key>rovicorp.com</key>
,其中定义了受这些设置影响的域,该域将不会应用于任何其他域。
NSTemporaryExceptionAllowsInsecureHTTPLoads
可以删除,我只是为了完成而添加了它,以防万一有人要使用HTTP请求。
希望这对您有帮助,
