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;
