4.5.4.3. Using cURL
Using tools such as cURL, we can consume the vCloud Networking and Security REST API. There is no need for document descriptions, because only touching each URL with the appropriate method and data causes an immediate response.
cURL, sometimes written as curl, is a set of C-based libraries in PHP that supports HTTP GET. cURL supports the following command line options:
*-i (HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, and the HTTP-version.
*-k Allow connections to SSL sites without certificates.
*-H Specify a custom HTTP header to pass to the server.
*-X Specifies a custom request method to use when communicating with the HTTP server. The specified request is used instead of the method otherwise used (which defaults to GET). Read the HTTP 1.1 specification for details and explanations. Common additional HTTP requests include POST and DELETE.
