我想与我的服务器安全地通信，这就是我正在做的事情......

NSURLProtectionSpace *protectionSpace = [challenge protectionSpace];
SecTrustRef trust = [protectionSpace serverTrust];
NSURLCredential *credential = [NSURLCredential credentialForTrust:trust];

    SecPolicyRef myPolicy = SecPolicyCreateBasicX509();

NSArray * certs = [[NSArray alloc] initWithObjects:(id)certificate,nil]; //certificate is my server's cert.
credential = [NSURLCredential credentialForTrust:trust];

    SecTrustSetAnchorCertificates(trust,
                                  (CFArrayRef) [NSArray arrayWithObject:(id) certificate ]);    

OSStatus status = SecTrustCreateWithCertificates(certs, myPolicy, &trust);

SecTrustResultType trustResult = 0;

if (status == noErr) {
    status = SecTrustEvaluate(trust, &trustResult);
}

    NSLog(@"Trust I get: %d", trustResult);
[certs release];

if (trustResult == kSecTrustResultRecoverableTrustFailure) {
    NSLog(@"Recoverable Failure");
    CFAbsoluteTime trustTime,currentTime,timeIncrement,newTime;
    CFDateRef newDate;

    trustTime = SecTrustGetVerifyTime(trust);             
    timeIncrement = 31536000;                               
    currentTime = CFAbsoluteTimeGetCurrent();              
    newTime = currentTime - timeIncrement;                  
    if (trustTime - newTime){                               
        newDate = CFDateCreate(NULL, newTime);              
        SecTrustSetVerifyDate(trust, newDate);            
        status = SecTrustEvaluate(trust, &trustResult);   
    }
    NSLog(@"Trust again:%d", trustResult);// AGAIN kSecTrustResultRecoverableTrustFailure(5) over here

}

任何人都知道它为什么会发生......似乎这与证书的到期无关（实际上也不是），但可能是原因。

谢谢你

SecTrustResultRecoverableTrustFailure如果发生

  • 证书是 md5 散列（IOS5）
  • 服务器不提供根证书和中间证书
  • 设置了 SecTrustSetAnchorCertificatesOnly(trust,YES) 并且锚证书仅在内置锚证书中
  • 证书已过期
  • ?

我通过将网络服务器配置为发送整个证书链而不是仅发送服务器证书来解决我的问题。

通过配置我的 apache mod_ssl： https ://httpd.apache.org/docs/2.2/mod/mod_ssl.html#sslcertificatechainfile
