C# Class Akamai.EdgeGrid.Auth.EdgeGridV1Signer

The EdgeGrid Signer is responsible for brokering a requests.This class is responsible for the core interaction logic given an API command and the associated set of parameters. When event is executed, the 'Authorization' header is decorated If connection is going to be reused, pass the persistent HttpWebRequest object when calling execute() TODO: support rebinding on IO communication errors (eg: connection reset) TODO: support Async callbacks and Async IO TODO: support multiplexing TODO: optimize and adapt throughput based on connection latency Author: [email protected] (Colin Bendell)

Public Methods

Method Description
EdgeGridV1Signer ( IList headers = null, long maxBodyHashSize = 2048 ) : System
Execute ( WebRequest request, ClientCredential credential, Stream uploadStream = null ) : Stream

Opens the connection to the {OPEN} API, assembles the signing headers and uploads any files.
Sign ( WebRequest request, ClientCredential credential, Stream uploadStream = null ) : WebRequest

Signs the given request with the given client credential.
Validate ( WebResponse response ) : void

Validates the response and attempts to detect root causes for failures for non 200 responses. The most common cause is due to time synchronization of the local server. If the local server is more than 30seconds out of sync then the API server will reject the request. TODO: catch rate limitting errors. Should delay and retry.
