ios - 使用自签名根证书的 SSLHandshake 失败 (-9808)

Question

我有带有 REST API 的自定义硬件设备。设备具有自签名根证书。我正在尝试进行简单的 GET 调用，但我的所有请求都失败了:

CFNetwork SSLHandshake failed (-9808)
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9808)

更多说明:

CFNetwork SSLHandshake failed (-9808)
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9808)
Error Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “192.168.68.97” which could put your confidential information at risk." UserInfo={NSURLErrorFailingURLPeerTrustErrorKey=<SecTrustRef: 0x7fa2fb219530>, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9808, NSErrorPeerCertificateChainKey=<CFArray 0x7fa2fb20ffd0 [0x1016d37b0]>{type = immutable, count = 1, values = (
    0 : <cert(0x7fa2f954a2e0) s: selfSignedRootCertificate i: selfSignedRootCertificate>
)}, NSUnderlyingError=0x7fa2fb3018e0 {Error Domain=kCFErrorDomainCFNetwork Code=-1202 "(null)" UserInfo={_kCFStreamPropertySSLClientCertificateState=0, kCFStreamPropertySSLPeerTrust=<SecTrustRef: 0x7fa2fb219530>, _kCFNetworkCFStreamSSLErrorOriginalValue=-9808, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9808, kCFStreamPropertySSLPeerCertificates=<CFArray 0x7fa2fb20ffd0 [0x1016d37b0]>{type = immutable, count = 1, values = (

)}}}, NSLocalizedDescription=The certificate for this server is invalid. You might be connecting to a server that is pretending to be “192.168.68.97” which could put your confidential information at risk., NSErrorFailingURLKey=https://192.168.68.97/api/switch/ctrl?switch=1&action=on, NSErrorFailingURLStringKey=https://192.168.68.97/api/switch/ctrl?switch=1&action=on, NSErrorClientCertificateStateKey=0}

我在 AFHTTPSessionManger 子类中的代码是

  NSData *myCertificate = [NSData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"selfSignedRootCertificate" ofType:@"cer"]];
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModePublicKey];
    securityPolicy.validatesDomainName = NO;
    securityPolicy.allowInvalidCertificates = YES;
    securityPolicy.pinnedCertificates = @[myCertificate];

并且我尝试根据 iOS 9.0 的变化向 plist 添加异常

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

我不知道我做错了什么。我的观点是将我的自签名根证书固定到应用程序以便能够使用 https 连接。你能帮我用正确的方法去做吗？

我有 AFNetworking (2.6.1)。

感谢您的帮助!

所以我终于找到了问题的根源。问题出在自定义硬件设备上的 ssl-library 中。在硬件上重新实现后，一切都很顺利。
