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.
/**
* 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);
}
}

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
