Member Function Documentation

constructor()

AwsRestClient::AwsRestClient::constructor	(	hash< auto >	opts,
		*softbool	do_not_connect
	)

creates the object with the given options

Example:

AwsRestClient rest({
    "url": "https://apigateway.eu-central-1.amazonaws.com",
    "aws_keyid": aws_keyid,
    "aws_secret": aws_secret.
});

Parameters

opts

valid options are: additional_methods: Optional hash with more but not-HTTP-standardized methods to handle. It allows HTTP extensions like e.g. WebDAV to work. The hash takes the method name as a key, and the value is a boolean True or False: indicating if the method requires a message body as well. Example: # add new HTTP methods for WebDAV. Both of them require body posting to the server {"additional_methods": {"PROPFIND": True, "MKCOL": True}}; aws_keyid: (required) the AWS key ID aws_region: the AWS region to use (ex: "us-east-1"); if it cannot be derived from the URL then it is a required option was_service: the AWS service to use (ex: "iam"); if it cannot be derived from the URL then it is a required option aws_secret: (required) the AWS secret access key value aws_token: a temporary session token from AWS Security Token Service for this HTTP session content_encoding: for possible values, see EncodingSupport; this sets the send encoding (if the "send_encoding" option is not set) and the requested response encoding (note that the RestClient class will only compress outgoing message bodies over CompressionThreshold bytes in size) default_path: The default path to use for new connections if a path is not otherwise specified in the connection URL default_port: The default port number to connect to if none is given in the URL error_passthru: if True then HTTP status codes indicating errors will not cause an REST-RESPONSE-ERROR exception to be raised, rather such responses will be passed through to the caller like any other response headers: an optional hash of headers to send with every request, these can also be overridden in request method calls http_version: Either '1.0' or '1.1' (default) for the claimed HTTP protocol version compliancy in outgoing message headers max_redirects: The maximum number of redirects before throwing an exception (the default is 5) proxy: The proxy URL for connecting through a proxy redirect_passthru: if True then redirect responses will be passed to the called instead of processed aws_s3: set to True to flag this object for use with AWS aws_s3, which requires special message encoding send_encoding: a send data encoding option or the value "auto" which means to use automatic encoding; if not present defaults to "gzip" content encoding on sent message bodies (note that the RestClient class will only compress outgoing message bodies over CompressionThreshold bytes in size) swagger: the path to a Swagger 2.0 REST schema file for API validation; only used if validator not provided (see the Swagger module) timeout: The timeout value in milliseconds (also can be a relative date-time value for clarity, ex: 30s) url: a string giving the URL to connect to; if not given then the target URL will be taken from any validator option, if given by calling AbstractRestSchemaValidator::getTargetUrl() validator: an AbstractRestSchemaValidator object to validate request and response messages; overrides swagger

do_not_connect

if False (the default), then a connection will be immediately established to the remote server

Exceptions

RESTCLIENT-ERROR	invalid option passed to constructor, unsupported data serialization, etc
AWSRESTCLIENT-ERROR	missing or invalid required option for AWS REST authentication or communication

Note

the data option is always set to "json"
