Installation

Using (MODX)EvolutionCMS.libraries.ddInstaller

Just run the following PHP code in your sources or Console:

// Include (MODX)EvolutionCMS.libraries.ddInstaller
require_once(
	$modx->getConfig('base_path')
	. 'assets/libs/ddInstaller/require.php'
);

// Install (MODX)EvolutionCMS.snippets.ddMakeHttpRequest
\DDInstaller::install([

Examples

Simple GET request

[[ddMakeHttpRequest?
	&requester=`{
		url: http://www.example.com?name=John&surname=Doe
	}`
]]

Simple POST request

Set data as HJSON:

[[ddMakeHttpRequest?
	&requester=`{
		url: http://www.example.com/
		data: {
			name: John
			surname: Doe
		}
	}`
]]

Or Query string:

[[ddMakeHttpRequest?
	&requester=`{
		url: http://www.example.com/
		data: name=John&surname=Doe
	}`
]]

Run the snippet through \DDTools\Snippet::runSnippet without DB and eval

\DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://www.example.com/',
			'data' => [
				'name' => 'John',
				'surname' => 'Doe',
			],
			'headers' => [
				'Accept: application/vnd.api+json',
				'Content-Type: application/vnd.api+json',
			],
			'proxy' => 'socks5://user:password@11.22.33.44:5555',
		],
	],
]);

Get only meta

$responseMeta = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://example.com/',
		],
		'outputter' => [
			'type' => 'meta',
		],
	],
]);

// Check if request was successful
if ($responseMeta->isSuccess){
	// Success
}else{
	// Error
	error_log('HTTP request failed: ' . $responseMeta->message);
}

Get both data and meta

$result = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/users',
		],
		'outputter' => [
			'type' => 'metaData',
		],
	],
]);

if ($result->meta->isSuccess){
	// Process response data
	$users = json_decode($result->data);
}

Convert result to JSON

// Get result as JSON string
$jsonString = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/users',
		],
		'outputter' => [
			'type' => 'metaData',
			'convertTo' => 'stringJsonAuto',
		],
	],
]);

// Now you can use it in JavaScript or save to file

Convert result to array

// Get response meta as PHP array
$metaArray = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/status',
		],
		'outputter' => [
			'type' => 'meta',
			'convertTo' => 'objectArray',
		],
	],
]);

// Access as array
if ($metaArray['isSuccess']){
	echo 'HTTP code: ' . $metaArray['code'];
}

Response data validation with dataProcessor

Validate response with simple value (e. g. string or number)

API returns simple value and if it equals to OK — it's success, otherwise — failure.

$result = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/check',
		],
		'dataProcessor' => [
			// Response contains data about success status
			'isCheckForSuccess' => true,
			// If value equals to `OK` — it's success, otherwise — failure
			'checkValue' => 'OK',
		],
		'outputter' => [
			'type' => 'meta',
		],
	],
]);

// Now isSuccess will be true only if:
// * CURL request succeeded
// * HTTP code is 2xx
// * Response equals `OK`
if ($result->isSuccess){
	// All good!
}

Validate response as object and check for success status

API response is an object and contains success property with value true (e. g. {"success": true}) — it's success, otherwise — failure.

$result = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/send',
			'method' => 'post',
			'data' => [
				'message' => 'Hello',
			],
		],
		'dataProcessor' => [
			// Response contains data about success status
			'isCheckForSuccess' => true,
			// Use `success` property to check for success status
			'checkPropName' => 'success',
			// Value to check for success status
			'checkValue' => true,
		],
		'outputter' => [
			'type' => 'metaData',
		],
	],
]);

// Now meta->isSuccess will be true only if:
// * CURL request succeeded
// * HTTP code is 2xx
// * Response is an object and contains `success` property with value `true` (e. g. `{"success": true}`)
if ($result->meta->isSuccess){
	// All good!
}else{
	// Something went wrong
}

Validate response as object, check for failure status and extract error message

API response is an object and contains status property with value fail (e. g. {"status": "fail"}) — it's failure, otherwise — success.

$result = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/send-sms',
			'method' => 'post',
			'data' => [
				'phone' => '[phone]',
			],
		],
		'dataProcessor' => [
			// Response contains data about failure status (e. g. `{"status": "fail"}`)
			'isCheckForSuccess' => false,
			// Use `status` property to check for failure status
			'checkPropName' => 'status',
			// Failure status value
			'checkValue' => 'fail',
			// Extract message from response
			'messagePropName' => 'message',
		],
		'outputter' => [
			'type' => 'metaData',
		],
	],
]);

if (!$result->meta->isSuccess){
	// Log error with message from API
	error_log('API error: ' . ($result->meta->message ?? 'Unknown error'));
}

Convert data and output simultaneously with dataProcessor->convertTo and outputter->convertTo

API returns JSON string '{"userId": "123", "userName": "John"}'. We want to:

1. Convert response data from JSON string to PHP object (using dataProcessor->convertTo)
2. Return both data and meta (using outputter->type = 'metaData')
3. Convert the whole result to JSON for frontend (using outputter->convertTo)

$jsonResult = \DDTools\Snippet::runSnippet([
	'name' => 'ddMakeHttpRequest',
	'params' => [
		'requester' => [
			'url' => 'https://api.example.com/user',
		],
		'dataProcessor' => [
			// Convert JSON string to PHP object before validation
			'convertTo' => 'objectStdClass',
		],
		'outputter' => [
			// Return both data and meta
			'type' => 'metaData',
			// Convert whole result to JSON
			'convertTo' => 'stringJsonObject',
		],
	],
]);

// Now $jsonResult is JSON string like:
// {"data": {"userId": "123", "userName": "John"}, "meta": {"isSuccess": true, ...}}
// Perfect for AJAX responses or saving to file
