Use cURL

The examples within this document use cURL to demonstrate how to access the OIG Self Service REST API.

Task 1: Install cURL

The examples within this document use the cURL command-line tool to demonstrate how to access the OIG Self Service REST API.

To connect securely to the server, you must install a version of cURL that supports SSL and provide an SSL certificate authority (CA) certificate file or bundle to authenticate against the Verisign CA certificate. For more information about authentication, see Authenticate.

The following procedure demonstrates how to install cURL on a Windows 64-bit system.

  1. In your browser, navigate to the cURL home page at http://curl.haxx.se and click Download in the left navigation menu.

  2. On the cURL Releases and Downloads page, locate the SSL-enabled version of the cURL software that corresponds to your operating system, click the link to download the ZIP file, and install the software.

  3. Navigate to the cURL CA Certs page at http://curl.haxx.se/docs/caextract.html and download the ca-bundle.crt SSL CA certificate bundle in the folder where you installed cURL.

Task 2: Set Environment Variable for cURL

In a command window, set the cURL environment variable, CURL_CA_BUNDLE, to the location of your local CA certificate bundle. For example:

C:\curl> set CURL_CA_BUNDLE=ca-bundle.crt

You are now ready to send requests to OIG using cURL.

Task 3: Invoke cURL

Invoke cURL and specify one or more of the command-line options defined in the following table, as required, to direct its execution.

cURL Option Description
-d, --data @file.json Identifies the file that contains the request body, in JSON format, on the local machine.
-H Defines the content type of the request document.
-i Displays response header information.
-X Indicates the type of request (for example, GET, POST).
-k Allows curl to perform insecure SSL connections and transfers. All SSL connections are attempted to be made secure by using the CA certificate bundle installed by default. This makes all insecure connections fail unless -k/--insecure is used.

For example:

curl -i -X GET -u <username>:<password> -H <request-header>:<value> https://<subdomain>.<domain>.com/<path>/<resource-path>
