NSURLSession 的 HTTPS 访问

/**

 接收到身份质询 Challenge

 身份质询保存在受保护空间内！

 * 完成回调参数

 - NSURLSessionAuthChallengeDisposition

    NSURLSessionAuthChallengePerformDefaultHandling = 1,        对身份质询的默认处理

    NSURLSessionAuthChallengeCancelAuthenticationChallenge = 2, 取消请求，忽略凭据参数

    NSURLSessionAuthChallengeRejectProtectionSpace = 3,         本次忽略质询

 - NSURLCredential 证书

    NSLog(@"%@", challenge.protectionSpace);

    // 判断身份质询方式是否是信任证书

        // 回调信任受保护空间中的身份质询

        completionHandler(NSURLSessionAuthChallengeUseCredential, credential);

NSURLConnection 的 HTTPS 访问

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    NSURL *url = [NSURL URLWithString:@"https://baidu.com"];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    [NSURLConnection connectionWithRequest:request delegate:self];

    }

}

    [self.data setData:nil];

}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {

    [self.data appendData:data];

    NSLog(@"%@", [[NSString alloc] initWithData:self.data encoding:NSUTF8StringEncoding]);

}

- (NSMutableData *)data {

    if (_data == nil) {

        _data = [NSMutableData data];

    }

}

AFN 的 HTTPS 访问

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    manager.securityPolicy.allowInvalidCertificates = YES;

    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

        NSLog(@"%@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);

    } failure:^(NSURLSessionDataTask *task, NSError *error) {

        NSLog(@"%@", error);

    }];

}
