Usage examples of php's curl encapsulation class

Before using the function, we need to open the php curl module (libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

Steps to enable php curl function library

1). Remove the ;extension=php_curl.dll in the windows/php.ini file; /*Use echo phpinfo(); to view the path of php.ini*/
2). Copy php5/libeay32.dll and ssleay32.dll to the system directory windows/
3).Restart apache

The code is as follows:

include_once('curl.class.php');
$aa =new Curl('');
$curlOptions = array(
CURLOPT_URL => "http://www.xx.com/addTicket.jsp", //Access URL
CURLOPT_RETURNTRANSFER => true, //Get the result and return it as a string
CURLOPT_REFERER => "ww.ww.ww/zw2",
CURLOPT_HTTPHEADER => array('X-FORWARDED-FOR:139.197.14.19', 'CLIENT-IP:127.0.0.1','Proxy-Client-IP:139.197.14.19','WL-Proxy-Client-IP:139.197 .14.19' ),
CURLOPT_HEADER => 1, //Get the return header information
//CURLOPT_SSL_VERIFYPEER => false, //Support SSL encryption
CURLOPT_POST => true, //Send with POST parameters
CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //Requested POST parameter string
CURLOPT_TIMEOUT => $aa->timeout //Time to wait for response
);
echo $aa->getResponseText($curlOptions);

cul processing class:

The code is as follows:

class Curl
{
public $cookieFile;
public $timeout = 160;
Public function __construct($dir){
$this->cookieFile = $this->getTemporaryCookieFileName($dir);
}
/**
* Set CURL parameters and send a request to get the response content
* @access private
* @param $curlOptions array curl setting parameter array
* @return string|false If the access is successful, the obtained information will be returned in string form; otherwise, false
*/
public function getResponseText($curlOptions) {
/* Set CURLOPT_RETURNTRANSFER to true */
if(!isset($curlOptions[CURLOPT_RETURNTRANSFER]) || $curlOptions[CURLOPT_RETURNTRANSFER] == false) {
$curlOptions[CURLOPT_RETURNTRANSFER] = true;
}
/* Initialize curl module */
$curl = curl_init();
/* Set curl options */
curl_setopt_array($curl, $curlOptions);
/* Send request and get response information */
$responseText = '';
try {
$responseText = curl_exec($curl);
if(($errno = curl_errno($curl)) != CURLM_OK) {
$errmsg = curl_error($curl);
throw new Exception($errmsg, $errno);
}
} catch (Exception $e) {
//exceptionDisposeFunction($e);
//print_r($e);
$responseText = false;
}
/* Close curl module */
curl_close($curl);
/* Return results */
return $responseText;
}
/**
* Convert Unicode string (u0000) to utf-8 string, tool function
* @access private
* @static
* @param $string string Unicode string
* @return string utf-8 string
*/
public function unicodeToUtf8($string) {
$string = str_replace('u', '', strtolower($string));
$length = strlen($string) / 4;
$stringResult = '';
for($i = 0; $i < $length; $i++) {
$charUnicodeHex = substr($string, $i * 4, 4);
$unicodeCode = hexdec($charUnicodeHex);
$utf8Code = '';
if($unicodeCode < 128) {
$utf8Code = chr($unicodeCode);
} else if($unicodeCode < 2048) {
$utf8Code .= chr(192 + (($unicodeCode - ($unicodeCode % 64)) / 64));
$utf8Code .= chr(128 + ($unicodeCode % 64));
} else {
$utf8Code .= chr(224 + (($unicodeCode - ($unicodeCode % 4096)) / 4096));
$utf8Code .= chr(128 + ((($unicodeCode % 4096) - ($unicodeCode % 64)) / 64));
$utf8Code .= chr(128 + ($unicodeCode % 64));
}
$stringResult .= $utf8Code;
}
return $stringResult;
}
private function getTemporaryCookieFileName($dir='.') {
return (str_replace("", '/', tempnam($dir, 'tmp')));
}
}
