Constructor Details

#initialize(config: nil, region: nil, endpoint: nil, signer: nil, proxy_settings: nil, retry_config: nil) ⇒ FunctionsInvokeClient

Creates a new FunctionsInvokeClient. Notes: If a config is not specified, then the global OCI.config will be used.

This client is not thread-safe

Either a region or an endpoint must be specified. If an endpoint is specified, it will be used instead of the region. A region may be specified in the config or via or the region parameter. If specified in both, then the region parameter will be used.

Parameters:

  • config (Config) (defaults to: nil) —

    A Config object.

  • region (String) (defaults to: nil) —

    A region used to determine the service endpoint. This will usually correspond to a value in Regions::REGION_ENUM, but may be an arbitrary string.

  • endpoint (String) (defaults to: nil) —

    The fully qualified endpoint URL

  • signer (OCI::BaseSigner) (defaults to: nil) —

    A signer implementation which can be used by this client. If this is not provided then a signer will be constructed via the provided config. One use case of this parameter is instance principals authentication, so that the instance principals signer can be provided to the client

  • proxy_settings (OCI::ApiClientProxySettings) (defaults to: nil) —

    If your environment requires you to use a proxy server for outgoing HTTP requests the details for the proxy can be provided in this parameter

  • retry_config (OCI::Retry::RetryConfig) (defaults to: nil) —

    The retry configuration for this service client. This represents the default retry configuration to apply across all operations. This can be overridden on a per-operation basis. The default retry configuration value is nil, which means that an operation will not perform any retries

def initialize(config: nil, region: nil, endpoint: nil, signer: nil, proxy_settings: nil, retry_config: nil)
  # If the signer is an InstancePrincipalsSecurityTokenSigner or SecurityTokenSigner and no config was supplied (they are self-sufficient signers)
  # then create a dummy config to pass to the ApiClient constructor. If customers wish to create a client which uses instance principals
  # and has config (either populated programmatically or loaded from a file), they must construct that config themselves and then
  # pass it to this constructor.
  #
  # If there is no signer (or the signer is not an instance principals signer) and no config was supplied, this is not valid
  # so try and load the config from the default file.
  config = OCI::Config.validate_and_build_config_with_signer(config, signer)

  signer = OCI::Signer.config_file_auth_builder(config) if signer.nil?

  @api_client = OCI::ApiClient.new(config, signer, proxy_settings: proxy_settings)
  @retry_config = retry_config

    @endpoint = endpoint + '/20181201'

Instance Method Details

#invoke_function(function_id, opts = {}, &block) ⇒ Response

Note:

Click here to see an example of how to use invoke_function API.

Invokes a function

Parameters:

  • function_id (String) —

    The OCID of this function.

  • opts (Hash) (defaults to: {}) —

    the optional parameters

  • [Block] (Hash) —

    a customizable set of options

Options Hash (opts):

  • :retry_config (OCI::Retry::RetryConfig) —

    The retry configuration to apply to this operation. If no key is provided then the service-level retry configuration defined by #retry_config will be used. If an explicit nil value is provided then the operation will not retry

  • :invoke_function_body (OCI::Functions::Models::Stream) —

    The body of the function invocation. Note: The maximum size of the request is limited. This limit is currently 6MB and the endpoint will not accept requests that are bigger than this limit.

  • :fn_intent (String) —

    An optional intent header that indicates to the FDK the way the event should be interpreted. E.g. 'httprequest', 'cloudevent'.

    Allowed values are: httprequest, cloudevent

  • :fn_invoke_type (String) —

    Indicates whether Oracle Functions should execute the request and return the result ('sync') of the execution, or whether Oracle Functions should return as soon as processing has begun ('detached') and leave result handling to the function. (default to sync) Allowed values are: detached, sync

  • :opc_request_id (String) —

    The unique Oracle-assigned identifier for the request. If you need to contact Oracle about a particular request, please provide the request ID.

  • :response_target (String, IO) —

    Streaming http body into a file (specified by file name or File object) or IO object if the block is not given

Returns:

  • (Response) —

    A Response object with data of type String if response_target and block are not given, otherwise with nil data
