Question

请提供一些用于生成iOS签名的演示或示例。 https://docs.aws.amazon.com/general/latest/gr/signature-v4-examples.html 链接不包含objective-c中的任何示例。

Answer 1

您可以参考实施签名请求的AWS SDK for iOS。这是使用AWSCore的AWSSignatureSignerUtility的一个示例。

您可以通过cocoapods获得AWSCore。试试

pod 'AWSCore'

在您的Podfile中。

    NSString *aString = @"a random string";
    NSString *secretKey = @"aKey";

    //unsupport algorithm, should return nil
    NSString *signature = [[AWSSignatureSignerUtility HMACSign:[aString dataUsingEncoding:NSUTF8StringEncoding]
                                                       withKey:secretKey
                                                usingAlgorithm:kCCHmacAlgMD5] aws_stringWithURLEncoding];

Answer 2

NSString *aString = @"***********"; NSString *secretKey = @"*********";

NSURL *apiLink = [NSURL URLWithString:@"https://*********"];


AWSStaticCredentialsProvider *creds = [[AWSStaticCredentialsProvider alloc] initWithAccessKey: aString secretKey: secretKey  ];

     AWSEndpoint *url1 = [[AWSEndpoint alloc] initWithRegion: AWSRegionAPEast1 serviceName: @"APIGateway" URL: apiLink ];
     AWSTask *sign = [AWSSignatureV4Signer generateQueryStringForSignatureV4WithCredentialProvider: creds httpMethod: AWSHTTPMethodGET  expireDuration: 300 endpoint:url1 keyPath: @"***" requestHeaders:NULL requestParameters:NULL signBody:true];

Answer 3

有多种创建declare sqlStr string; sqlStr = 'SELECT 1 AS column1, 2 AS column2 INTO #temp FROM system.iota'; execute immediate sqlStr; select * from #temp;

的方法

在AWS SDK
借助开源代码共享here

对于 AWS SDK，以下功能会有所帮助
