Class ClasspathJsonFileCredentialsProvider

java.lang.Object

com.ibm.cloud.objectstorage.auth.ClasspathJsonFileCredentialsProvider

All Implemented Interfaces:

AWSCredentialsProvider

public class ClasspathJsonFileCredentialsProvider
extends Object
implements AWSCredentialsProvider

AWSCredentialsProvider implementation that loads AWS security credentials from a json file on the classpath. The default constructor creates a credentials provider that loads the credentials from a file named cos_credentials on the classpath, but which file to use from the classpath can also be controlled through the one-argument constructor.

The IBM API key is expected to be in the apiKey property and the IBM resource instance id is expected to be in the resource_instance_id property.

Constructor and Description
ClasspathJsonFileCredentialsProvider() Creates a new ClasspathJsonFileCredentialsProvider that will attempt to load the cos_credentials file from the classpath to read IBM security credentials.
ClasspathJsonFileCredentialsProvider(String credentialsFilePath) Creates a new ClasspathJsonFileCredentialsProvider that will attempt to load a custom file from the classpath to read IBM security credentials.

Constructor Detail

ClasspathJsonFileCredentialsProvider

public ClasspathJsonFileCredentialsProvider()

Creates a new ClasspathJsonFileCredentialsProvider that will attempt to load the cos_credentials file from the classpath to read IBM security credentials.

ClasspathJsonFileCredentialsProvider

public ClasspathJsonFileCredentialsProvider(String credentialsFilePath)

Creates a new ClasspathJsonFileCredentialsProvider that will attempt to load a custom file from the classpath to read IBM security credentials.

Parameters:

credentialsFilePath - The custom classpath resource path to a json file from which the IBM security credentials should be loaded. For example,

• com/mycompany/credentials.json
• beta-credentials.json
• cos_credentials

Method Detail

getCredentials

public AWSCredentials getCredentials()

Description copied from interface: AWSCredentialsProvider

Returns AWSCredentials which the caller can use to authorize an AWS request. Each implementation of AWSCredentialsProvider can chose its own strategy for loading credentials. For example, an implementation might load credentials from an existing key management system, or load new credentials when credentials are rotated.

Specified by:

getCredentials in interface AWSCredentialsProvider

Returns:

AWSCredentials which the caller can use to authorize an AWS request.

refresh

public void refresh()

Description copied from interface: AWSCredentialsProvider

Forces this credentials provider to refresh its credentials. For many implementations of credentials provider, this method may simply be a no-op, such as any credentials provider implementation that vends static/non-changing credentials. For other implementations that vend different credentials through out their lifetime, this method should force the credentials provider to refresh its credentials.

Specified by:

refresh in interface AWSCredentialsProvider

toString

public String toString()

Overrides:

toString in class Object
