Util_Http

HTTP Utility Library

HTTP

The Util.Http package provides a set of APIs that allows applications to use the HTTP protocol. It defines a common interface on top of CURL and AWS so that it is possible to use one of these two libraries in a transparent manner.

Client

The Util.Http.Clients package defines a set of API for an HTTP client to send requests to an HTTP server.

GET request

To retrieve a content using the HTTP GET operation, a client instance must be created. The response is returned in a specific object that must therefore be declared:

Http     : Util.Http.Clients.Client;
Response : Util.Http.Clients.Response;

Before invoking the GET operation, the client can setup a number of HTTP headers.

Http.Add_Header ("X-Requested-By", "wget");

The GET operation is performed when the Get procedure is called:

Http.Get ("http://www.google.com", Response);

Once the response is received, the Response object contains the status of the HTTP response, the HTTP reply headers and the body. A response header can be obtained by using the Get_Header function and the body using Get_Body:

Body : constant String := Response.Get_Body;
