Constructor Detail

AwsSignature4Signer

public AwsSignature4Signer(AwsServiceEndPoint serviceEndPoint,
                           AwsCredentialsProvider credentialsProvider,
                           boolean doubleUrlEncode)

Constructs an instance

See also: https://github.com/aws/aws-sdk-js/issues/853 for why we need the doubleUrlEncode parameter, and why by default it is set to true.

Parameters:

serviceEndPoint - the service Endpoint

credentialsProvider - the credentials provider

doubleUrlEncode - whether canonical request URL encode already URL encoded paths

AwsSignature4Signer

public AwsSignature4Signer(AwsServiceEndPoint serviceEndPoint,
                           AwsCredentialsProvider credentialsProvider)

Constructs an instance that double encodes URL paths

Parameters:

serviceEndPoint - the service Endpoint

credentialsProvider - the credentials provider
