Form class submitted through curl to simulate post and get methods_PHP tutorial

I have been working on a project recently. The backend has been completed but the template for the frontend has not been downloaded yet, 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.

Copy code The code is as follows:

/**
* Class SimulantForm 模拟表单
*/
class SimulantForm {
/**
* @var 要提交的页面url
*/
protected $_url;

/**
* @var resource curl_init()返回的curl句柄
*/
protected $_ch;

/**
* 初始化一个表单
* @param $_url url
*/
public function __construct($_url) {
$this->_ch = curl_init();
  $this->setUrl($_url);
  curl_setopt($this->_ch, CURLOPT_RETURNTRANSFER, 1);
 }

    /**
     * get方式提交
     * @param array|string 表单数据
     * @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;
 }

    /**
     * post方式提交
     * @param array|string 表单数据
     * @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;
 }

    /**
     * 返回错误信息
     * @return array array[0]:错误号 , array[1]:错误信息
     */
    public function getLastError() {
  return array(curl_errno($this->_ch), curl_error($this->_ch));
 }

 /**
  * 设置SETOPT_COOKIEFILE
  * @param string $_cookieFile 文件真实路径
  */
 public function setCookieFile($_cookieFile) {
  curl_setopt($this->_ch, CURLOPT_COOKIEFILE, $_cookieFile);
 }

 /**
  * 设置SETOPT_COOKIEJAR
  * @param string $_cookieFile 文件真实路径
  */
    public function setCookieJar($_cookieFile) {
        curl_setopt($this->_ch, CURLOPT_COOKIEJAR, $_cookieFile);
    }

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

    /**
     * 设置get方式提交时的数据
     * @param $_get_data 字符串或数组
     * @return mixed
     */
    protected function _setGetData($_get_data) {
        if(is_array($_get_data)) {
           return $this->_getDataToString($_get_data);
        } elseif(is_string($_get_data)) {
           return $_get_data;
        }
    }

    /**
     * 设置post方式提交时的数据
     * @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) {
$result_string = '?';
array_walk($_get_data, function ($value, $key) use (&$result_string) {
if(is_array($value)) {
foreach($value as $sec_value) {
$result_string .= $key . '[]=' . $sec_value . ' &';
}
} else {
$result_string .= $key . '=' . $value . '&';
}
});
return substr( $result_string, 0, strlen($result_string) - 1);
}
}
