A simulated form class that can simulate post and get submissions.

In a recent project, the backend has been completed but the frontend template has not yet been downloaded, so testing is more troublesome. So I wrote a simple script to simulate form submission through curl. Data can be submitted in two ways: array and string.

/**
 * Class SimulantForm simulation form
*/
class SimulantForm {
 /**
 * @var The page url to be submitted
*/
 protected $_url;

 /**
 *@var resource The curl handle returned by curl_init()
*/
 protected $_ch ;

 /**
 * Initialize a form
 * @param $_url url
*/
 public function __construct($_url) {
 $this->_ch = curl_init();
 $this->setUrl($_url);
 curl_setopt($this- >_ch, CURLOPT_RETURNTRANSFER, 1);
 }

 /**
 *Submit via get method
 * @param array|string form data
 * @return mixed
*/
 public function get($_data = '') {
 $this->_url .= $this->_setGetData($ _data);
 $this->setUrl($this->_url);
 $result = curl_exec($this->_ch);
 curl_close($this->_ch);
 return $result;
 }

 /**
 * Submit via post
 * @param array|string form data
 * @return mixed
*/
 public function post($_data) {
 curl_setopt($this->_ch, CURLOPT_POST, 1);
 $this->_setPostData($_data);
 $result = curl_exec($this->_ch);
 curl_close($this->_ch);
 return $result;
 }

 /**
 * Return error message
 * @return array array[0]: error number, array[1]: error message
*/
 public function getLastError() {
 return array( curl_errno($this->_ch), curl_error($this->_ch));
 }

 /**
 * Set SETOPT_COOKIEFILE
 * @param string $_cookieFile file real path
*/
 public function setCookieFile($_cookieFile) {
 curl_setopt($this-> _ch, CURLOPT_COOKIEFILE, $_cookieFile);
 }

 /**
 * Set SETOPT_COOKIEJAR
 * @param string $_cookieFile file real path
*/
 public function setCookieJar($_cookieFile) {
 curl_setopt($this->_ch, CURLOPT_COOKIEJAR, $_cookieFile);
 }

 / **
 * Set url
 * @param $_url
*/
 protected function setUrl($_url) {
 $this->_url = $_url;
 curl_setopt($this->_ch, CURLOPT_URL, $_url);
 }

 /**
 * Set the data when submitting in get mode
 * @param $_get_data string or array
 * @return mixed
*/
 protected function _setGetData($_get_data) {
 if(is_array($_get_data)) {
 return $this->_getDataToString($_get_data);
 } elseif(is_string($_get_data)) {
 return $_get_data;
 }
 }

 /**
 * Set the data when submitting in post mode
 * @param array|string $_post_data
*/
 protected function _setPostData ($_post_data) {
 curl_setopt($this->_ch, CURLOPT_POSTFIELDS, $_post_data);
 }

 /**
 * Parse the submitted information in array form into a string for submission via get method
 * @param array $_get_data
 * @return string
*/
 protected function _getDataToString(array $_get_data) {
 return '?' . http_build_query($_get_data); //Refer to the first floor, replaced by the http_build_query function, and the editing function of oschina is really terrible!
 }
}
