AFNetworking 3.0 https请求忽略证书验证

1、修改AFNetworking中修改源码，在AFSecurityPolicy.m注释掉这几句

- (BOOL)evaluateServerTrust:(SecTrustRef)serverTrust
forDomain:(NSString *)domain
{
//    if (domain && self.allowInvalidCertificates && self.validatesDomainName && (self.SSLPinningMode == GMAFSSLPinningModeNone || [self.pinnedCertificates count] == 0)) {
//        // https://developer.apple.com/library/mac/documentation/NetworkingInternet/Conceptual/NetworkingTopics/Articles/OverridingSSLChainValidationCorrectly.html //        //  According to the docs, you should only trust your provided certs for evaluation.
//        //  Pinned certificates are added to the trust. Without pinned certificates,
//        //  there is nothing to evaluate against.
//        //
//        //  From Apple Docs:
//        //          "Do not implicitly trust self-signed certificates as anchors (kSecTrustOptionImplicitAnchors).
//        //           Instead, add your own (self-signed) CA certificate to the list of trusted anchors."
//        NSLog(@"In order to validate a domain name for self signed certificates, you MUST use pinning.");
//        return NO;
//    }

2、在使用的时候添加
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

AFSecurityPolicy *securityPolicy = [AFSecurityPolicy defaultPolicy];
// allowInvalidCertificates 是否允许无效证书（也就是自建的证书），默认为NO
// 如果是需要验证自建证书，需要设置为YES
securityPolicy.allowInvalidCertificates = YES;
manager.securityPolicy = securityPolicy;
