Method Detail

sign

public SdkHttpFullRequest sign(SdkHttpFullRequest request,
                               ExecutionAttributes executionAttributes)

Deprecated.

Description copied from interface: Signer

Method that takes in an request and returns a signed version of the request.

Parameters:

request - The request to sign

executionAttributes - Contains the attributes required for signing the request

Returns:

A signed version of the input request

sign

public SdkHttpFullRequest sign(SdkHttpFullRequest request,
                               Aws4SignerParams signingParams)

Deprecated.

presign

public SdkHttpFullRequest presign(SdkHttpFullRequest requestToSign,
                                  ExecutionAttributes executionAttributes)

Deprecated.

Description copied from interface: Presigner

Method that takes in an request and returns a pre signed version of the request.

Parameters:

requestToSign - The request to presign

executionAttributes - Contains the attributes required for pre signing the request

Returns:

A pre signed version of the input request

presign

public SdkHttpFullRequest presign(SdkHttpFullRequest request,
                                  Aws4PresignerParams signingParams)

Deprecated.

processRequestPayload

protected void processRequestPayload(SdkHttpFullRequest.Builder mutableRequest,
                                     byte[] signature,
                                     byte[] signingKey,
                                     Aws4SignerRequestParams signerRequestParams,
                                     Aws4SignerParams signerParams)

Deprecated.

Subclass could override this method to perform any additional procedure on the request payload, with access to the result from signing the header. (e.g. Signing the payload by chunk-encoding). The default implementation doesn't need to do anything.

Specified by:

processRequestPayload in class AbstractAws4Signer<Aws4SignerParams,Aws4PresignerParams>

processRequestPayload

protected void processRequestPayload(SdkHttpFullRequest.Builder mutableRequest,
                                     byte[] signature,
                                     byte[] signingKey,
                                     Aws4SignerRequestParams signerRequestParams,
                                     Aws4SignerParams signerParams,
                                     SdkChecksum sdkChecksum)

Deprecated.

This method overloads processRequestPayload with sdkChecksum. The sdkChecksum if passed, is computed while processing request payload.

Specified by:

processRequestPayload in class AbstractAws4Signer<Aws4SignerParams,Aws4PresignerParams>

calculateContentHashPresign

protected String calculateContentHashPresign(SdkHttpFullRequest.Builder mutableRequest,
                                             Aws4PresignerParams signerParams)

Deprecated.

Calculate the hash of the request's payload. In case of pre-sign, the existing code would generate the hash of an empty byte array and returns it. This method can be overridden by sub classes to provide different values (e.g) For S3 pre-signing, the content hash calculation is different from the general implementation.

Specified by:

calculateContentHashPresign in class AbstractAws4Signer<Aws4SignerParams,Aws4PresignerParams>
