我们正在尝试在我们的 iOS 应用程序中实现 ssl 以连接到运行在 Tomcat Webserver 中的 Rest webservices。在 tomcat 配置中将 clientAuth 设置为 true 时面临以下问题：

这是一个代码片段，展示了我们如何创建 AlamoFire 会话管理器：
import Foundation
import Alamofire
class HttpUtils {
static let utils = HttpUtils()
var alamoFireSSLManager : SessionManager?
public static func getJSONRequestWithBody(url: String, targetViewController: UIViewController?, params : Dictionary<String, String>,
handler: @escaping RiderRideRestClient.responseJSONCompletionHandler){
let isNetworkAvailable = Reachability.isConnectedToNetwork()
if isNetworkAvailable {
utils.createAlamoFireManager()
utils.alamoFireSSLManager!
.request(url, method: .get, parameters: params, encoding: URLEncoding.methodDependent, headers: nil)
.responseJSON(completionHandler: {
(response) in
handleResponse(response: response, completionHandler: handler)
})
}
else {
handler(nil, Errors.NetworkConnectionNotAvailableError)
}
}
func createAlamoFireManager() {
if (HttpUtils.utils.alamoFireSSLManager == nil) {
let mydomainCertificates = getCertificates(filename: "mydomaincertificate", type: "cer")
let mydomainTrustPolicy = ServerTrustPolicy.pinCertificates(
certificates: mydomainCertificates,
validateCertificateChain: true,
validateHost: true)
let sub2DomainCertificates = getCertificates(filename: "sub2domaincertificate", type: "cer")
let sub2DomainTrustPolicy = ServerTrustPolicy.pinCertificates(
certificates: sub2DomainCertificates,
validateCertificateChain: true,
validateHost: true)
var serverTrustPolicies = [String : ServerTrustPolicy] ()
serverTrustPolicies[example.com] = mydomainTrustPolicy
serverTrustPolicies[sub2.example.com] = sub2DomainTrustPolicy
serverTrustPolicies[sub3.example.com] = ServerTrustPolicy.disableEvaluation
HttpUtils.utils.alamoFireSSLManager = SessionManager(configuration: URLSessionConfiguration.default,
serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies))
}
}
func getCertificates(filename : String, type : String) -> [SecCertificate] {
let url = Bundle.main.url(forResource: filename, withExtension: type)!
let localCertificate = try! Data(contentsOf: url) as CFData
guard let certificate = SecCertificateCreateWithData(nil, localCertificate)
else { return [] }
return [certificate]
}
}
我尝试将以下内容添加到 info.plist 的“应用程序传输安全设置”中：
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSExceptionDomains</key>
<dict>
<key>sub2.example.com</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
<key>example.com</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
</dict>
然后我收到以下错误：

我使用以下命令生成了证书，并确保在 Xcode 中将此证书应用于我的目标：
openssl s_client -connect example.com:8443 -servername example.com < /dev/null | openssl x509 -outform DER > mydomaincertificate.cer
我检查了几个 SO 帖子以了解问题所在，但其他帖子中给出的答案都没有奏效。我究竟做错了什么？
