自己制作的證書

很明顯沒有綠鎖, 當打開的時候會詢問是否連接這個不受信任的連接才會進一步打開, 下面就來一步步的實現(包括怎么制作證書)

iOS使用自簽名證書實現HTTPS請求

iOS Https協議 自簽證書訪問數據參考這個例子的時候,博主自帶的Demo AFN框架請求不了數據, 我用了最新AFN版本的成功返回數據

還可以參考一下
iOS 10 適配 ATS app支持https通過App Store審核

我在利用原生的代碼測試時遇到的問題

@interface ViewController () @end @implementation ViewController - (void)viewDidLoad { } - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:[NSOperationQueue mainQueue]];NSURLSessionDataTask *task =[session dataTaskWithURL:[NSURL URLWithString:@"https://www.baidu.com"] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { NSLog(@"%@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]); }];[task resume]; } - (void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask didReceiveResponse:(NSURLResponse *)responsecompletionHandler:(void (^)(NSURLSessionResponseDisposition disposition))completionHandler { NSLog(@"接收到服務器響應"); //注意：這里需要使用completionHandler回調告訴系統應該如何處理服務器返回的數據 //默認是取消 /**NSURLSessionResponseCancel = 0,默認的處理方式，取消NSURLSessionResponseAllow = 1, 接收服務器返回的數據NSURLSessionResponseBecomeDownload = 2,變成一個下載請求NSURLSessionResponseBecomeStream 變成一個流*/ completionHandler(NSURLSessionResponseAllow); } - (void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask didReceiveData:(NSData *)data { NSLog(@"獲取到服務段數據"); NSLog(@"%@",[self jsonToDictionary:data]); } - (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didCompleteWithError:(nullable NSError *)error { NSLog(@"請求完成%@", error); } - (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challengecompletionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler { NSLog(@"證書認證"); if ([[[challenge protectionSpace] authenticationMethod] isEqualToString: NSURLAuthenticationMethodServerTrust]) { do { SecTrustRef serverTrust = [[challenge protectionSpace] serverTrust]; NSCAssert(serverTrust != nil, @"serverTrust is nil"); if(nil == serverTrust) break; /* failed */ /***導入多張CA證書（Certification Authority，支持SSL證書以及自簽名的CA），請替換掉你的證書名稱*/ NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"ca" ofType:@"cer"];//自簽名證書 NSData* caCert = [NSData dataWithContentsOfFile:cerPath]; NSCAssert(caCert != nil, @"caCert is nil"); if(nil == caCert) break; /* failed */ SecCertificateRef caRef = SecCertificateCreateWithData(NULL, (__bridge CFDataRef)caCert); NSCAssert(caRef != nil, @"caRef is nil"); if(nil == caRef) break; /* failed */ //可以添加多張證書 NSArray *caArray = @[(__bridge id)(caRef)]; NSCAssert(caArray != nil, @"caArray is nil"); if(nil == caArray) break; /* failed */ //將讀取的證書設置為服務端幀數的根證書 OSStatus status = SecTrustSetAnchorCertificates(serverTrust, (__bridge CFArrayRef)caArray); NSCAssert(errSecSuccess == status, @"SecTrustSetAnchorCertificates failed"); if(!(errSecSuccess == status)) break; /* failed */ SecTrustResultType result = -1; //通過本地導入的證書來驗證服務器的證書是否可信 status = SecTrustEvaluate(serverTrust, &result); if(!(errSecSuccess == status)) break; /* failed */ NSLog(@"stutas:%d",(int)status); NSLog(@"Result: %d", result); BOOL allowConnect = (result == kSecTrustResultUnspecified) || (result == kSecTrustResultProceed); if (allowConnect) { NSLog(@"success"); }else { NSLog(@"error"); } /* kSecTrustResultUnspecified and kSecTrustResultProceed are success */ if(! allowConnect) { break; /* failed */ } #if 0 /* Treat kSecTrustResultConfirm and kSecTrustResultRecoverableTrustFailure as success */ /* since the user will likely tap-through to see the dancing bunnies */ if(result == kSecTrustResultDeny || result == kSecTrustResultFatalTrustFailure || result == kSecTrustResultOtherError) break; /* failed to trust cert (good in this case) */ #endif // The only good exit point NSLog(@"信任該證書"); NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]; completionHandler(NSURLSessionAuthChallengeUseCredential,credential); return [[challenge sender] useCredential: credential forAuthenticationChallenge: challenge]; } while(0); } // Bad dog NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]; completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge,credential); return [[challenge sender] cancelAuthenticationChallenge: challenge]; } - (NSDictionary *)jsonToDictionary:(NSData *)jsonData { NSError *jsonError; NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableLeaves error:&jsonError]; return resultDic; } @end 

下面說說我在配置自己制作證書過程中遇到的問題:

1.轉換證書: 把后臺給你的.crt證書轉化為.cer后綴

終端命令行openssl x509 -in 你的證書.crt -out 你的證書.cer -outform der

2.利用系統的方法找不到

 - (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challengecompletionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler { NSLog(@"證書認證"); } 

這個方法的時候, 是因為后臺的傳輸協議還沒升級到TLS1.2, 叫后臺升級后就可以來到驗證證書的這個方法了.

3.拖入證書讀取不出證書數據

參考: https的證書錯誤，錯誤碼-1012問題及解決方案

SDWebImage: 項目中大家用到AFN請求網絡數據, 升級驗證SSL證書的方案相信你看完上面的參考文章已經沒問題了, 我給出的代碼, 自定義網絡請求也沒問題了, 還有就是SDWebImage框架的請求HTTPS的圖片時,大家可以繞過證書驗證去加載圖片

[imageView sd_setImageWithURL:[NSURL URLWithString:urlString] placeholderImage:self.placeholder options:SDWebImageAllowInvalidSSLCertificates]; 

希望幫到你。
