PHP's Curl wrapper class usage Example
We need to open the PHP Curl module before using the function (Libeay32.dll, Ssleay32.dll, Php5ts.dll, Php_curl.dll)
To open the PHP Curl Library
1). Remove the Windows/php.ini file; Extension=php_curl.dll Front; /* with Echo phpinfo (); View PHP.ini's Path */
2). Copy the Php5/libeay32.dll,ssleay32.dll to the system directory windows/
3). Restart Apache
The code is as follows:
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,//Gets the result as a string return
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 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 parameter and send request to get response content
* @access Private
* @param $curlOptions Array curl to set parameter arrays
* @return String|false Access is successful, returns the obtained information in string form, otherwise false
*/
Public Function GetResponseText ($curlOptions) {
/* Set Curlopt_returntransfer to True */
if (!isset ($curlOptions [curlopt_returntransfer]) | | $curlOptions [Curlopt_returntransfer] = = False) {
$curlOptions [Curlopt_returntransfer] = true;
}
/* Initialize the 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);
$responseText = false;
}
/* Turn off the Curl module */
Curl_close ($curl);
/* Return results */
return $responseText;
}
/**
* Convert Unicode strings (u0000) to utf-8 strings, tool functions
* @access Private
* @static
* @param $string string Unicode string
* @return String Utf-8 strings
*/
Public Function UnicodeToUtf8 ($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);
$utf 8Code = ";
if ($unicodeCode < 128) {
$utf 8Code = Chr ($unicodeCode);
} else if ($unicodeCode < 2048) {
$utf 8Code. = Chr (192 + (($unicodeCode-($unicodeCode% 64))/64);
$utf 8Code. = Chr (+ ($unicodeCode% 64));
} else {
$utf 8Code. = Chr (224 + (($unicodeCode-($unicodeCode% 4096))/4096);
$utf 8Code. = Chr ((($unicodeCode% 4096)-($unicodeCode% 64))/64);
$utf 8Code. = Chr (+ ($unicodeCode% 64));
}
$stringResult. = $utf 8Code;
}
return $stringResult;
}
Private Function gettemporarycookiefilename ($dir = '. ') {
Return (Str_replace ("", '/', Tempnam ($dir, ' tmp ')));
}
}
