curl with OAuth2 Client Credentials

See more CURL Examples

This example shows how to run a simple CURL command with an OAuth2 access token for authorization. We use CURL to retrieve a SharePoint site ID, and Chilkat automatically fetches the OAuth2 access token using the provided credentials. Chilkat2 Perl

use Chilkat2;

# This example will run the following curl command

# curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \
#   -H "Authorization: Bearer ACCESS_TOKEN" \
#   -H "Accept: application/json"

my $sb = Chilkat2::StringBuilder->new;
$sb->AppendLn('curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \\');
$sb->AppendLn('  -H "Authorization: Bearer ACCESS_TOKEN" \\');
$sb->AppendLn('  -H "Accept: application/json"');

# Build the JSON that provides information for getting the OAuth2 access token using the OAuth2 client credentials flow.
my $jsonOAuth2 = Chilkat2::JsonObject->new;

$jsonOAuth2->UpdateString('oauth2.client_id', 'CLIENT_ID');
$jsonOAuth2->UpdateString('oauth2.client_secret', 'CLIENT_SECRET');
$jsonOAuth2->UpdateString('oauth2.scope', 'https://graph.microsoft.com/.default');
$jsonOAuth2->UpdateString('oauth2.token_endpoint', 'https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token');

my $httpCurl = Chilkat2::HttpCurl->new;

# Provide the information for getting the OAuth2 access token from the token endpoint
# Note: The Authorization header specified in the curl command will be ignored and replaced using the OAuth2 access token obtained at runtime from the token endpoint.
$httpCurl->SetAuth($jsonOAuth2);

# The placeholders {{sharepoint_hostname}} and {{site_name}} represent variables that must be defined before execution.
# When DoYourThing runs the curl command, it automatically substitutes these placeholders with their corresponding values.
# Below are the values assigned to these variables:
$httpCurl->SetVar('sharepoint_hostname', 'example.sharepoint.com');
$httpCurl->SetVar('site_name', 'test');

# Run the curl command.
my $success = $httpCurl->DoYourThing($sb->GetAsString());

    print $httpCurl->LastErrorText, "\n";
