  • Instantiates the OAuth2ClientCredentialsAuthenticationParameters from the SAP BTP configuration object. The configuration object is expected in the following format:

    let configuration: [String: String] = [
    "tokenEndpointURL": "<#token endpoint URL string#>",
    "scope": "<#scope#>", // Optional, structure described at https://tools.ietf.org/html/rfc6749#section-3.3
    "kState": "<#state#>"
    "name": "<#name#>",
    "secret": "<#secret#>"
]

    The URL strings are converted to URL using the URL object’s “string” initializer. If the initializer returns nil, an error is raised.

    Throws

    ConfigurationError if the configuration is not matching.

    Declaration

    Swift

    public init(discoveryServiceConfig config: Any) throws

    Parameters

    config
