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. Perl

use chilkat();

$success = 0;

# 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"

$sb = chilkat::CkStringBuilder->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.
$jsonOAuth2 = chilkat::CkJsonObject->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");

$httpCurl = chilkat::CkHttpCurl->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.
$success = $httpCurl->DoYourThing($sb->getAsString());
if ($success == 0) {
    print $httpCurl->lastErrorText() . "\r\n";
    exit;
}

$responseJson = chilkat::CkJsonObject->new();
$responseJson->put_EmitCompact(0);

$httpCurl->GetResponseJson($responseJson);

$statusCode = $httpCurl->get_StatusCode();
print "response status code: " . $statusCode . "\r\n";

print $responseJson->emit() . "\r\n";
