here.platform.credentials module

This module provides a PlatformCredentials class to be used for authentication.

A credentials object can be created from a credentials.properties file obtained from the HERE platform portal or from environment variables or from a access-token file generated in a pipeline.

class here.platform.credentials.CredentialsType(value)
Bases: Enum

CredentialsType enum defines the different types of credentials supported. Types: Credentials, Token.

Credentials = 1

Token = 2

class here.platform.credentials.PlatformCredentials(cred_type: CredentialsType, cred_properties: dict)
Bases: object

PlatformCredentials provides functions for dealing with the HERE platform Credentials.

Credentials can be read from the following locations:

• The default location: “~/.here/credentials.properties”

• A custom path to a credentials properties file

• Environment variables

classmethod from_credentials_file(path: str) → PlatformCredentials
Return the credentials object from a specified credentials path.

Parameters:
path – path to a HERE platform credentials.properties file.

Returns:
credentials

Raises:
ConfigException – Erroneous credentials.properties file in path

classmethod from_default() → PlatformCredentials
Return the credentials object from the default credential path at ‘~/.here/credentials.properties’.

If environmental variables are set, these values will override the ones found in the default file.

If no default file is found, this method will try to read the credentials from the environmental variables.

Returns:
credentials

classmethod from_env() → PlatformCredentials
Return the credentials object from the following environment variables:

- HERE_USER_ID

• HERE_CLIENT_ID

• HERE_ACCESS_KEY_ID

• HERE_ACCESS_KEY_SECRET

• HERE_TOKEN_ENDPOINT_URL (optional)

• HERE_TOKEN_SCOPE (optional)

Returns:
credentials parsed from the environment variables

Raises:
ConfigException – missing environmental variables that are mandatory

classmethod from_token_file(path: str) → PlatformCredentials
Return the credentials from a specified token file path.

Parameters:
path – path to a HERE platform token file.

Returns:
credentials

Raises:
ConfigException – Erroneous token file in path

patch_using_env()

Patch the credentials by reading the following environment variables and applying them accordingly.

- HERE_USER_ID

• HERE_CLIENT_ID

• HERE_ACCESS_KEY_ID

• HERE_ACCESS_KEY_SECRET

• HERE_TOKEN_ENDPOINT_URL

• HERE_TOKEN_SCOPE (optional)

Whenever such an environment variable is set, it overrides the one loaded from file.
