1、修改AFNetworking中修改源碼，在AFSecurityPolicy.m注釋掉這幾句

- (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;  
//    }  

或者可以添加一個宏開關“openHttpsSSL”，便于控制，類似如下代碼

- (BOOL)evaluateServerTrust:(SecTrustRef)serverTrust
                  forDomain:(NSString *)domain
{
    if (openHttpsSSL && domain && self.allowInvalidCertificates && self.validatesDomainName && (self.SSLPinningMode == AFSSLPinningModeNone || [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、在使用的時候添加

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];  
            manager.responseSerializer = [AFHTTPResponseSerializer serializer];  
            manager.requestSerializer = [AFJSONRequestSerializer serializer];  
  
            AFSecurityPolicy *securityPolicy = [AFSecurityPolicy defaultPolicy];  
            // allowInvalidCertificates 是否允許無效證書（也就是自建的證書），默認為NO  
            // 如果是需要驗證自建證書，需要設置為YES  
            securityPolicy.allowInvalidCertificates = YES;  
            manager.securityPolicy = securityPolicy;  

3、如果需要在http 頭里面添加用戶名和密碼驗證，添加

[request.operationManager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"用戶名" password:@"密碼"];
