我正在为一个实时网站设置信用卡处理。PHP 没有在 CURL 支持下编译,我不想让网站停止使用它重新编译 PHP,所以我尝试使用与提供的示例代码不同的方法。
示例 CURL 代码:
function send($packet, $url) {
$header = array("MIME-Version: 1.0","Content-type: application/x-www-form-urlencoded","Contenttransfer-encoding: text");
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt ($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
// Uncomment for host with proxy server
// curl_setopt ($ch, CURLOPT_PROXY, "http://proxyaddress:port");
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $packet);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_TIMEOUT, 10);
// send packet and receive response
$response = curl_exec($ch);
curl_close($ch);
return($response);
}
我尝试使用不同的方法:
function send($packet, $host, $path) {
$content = '';
$flag = false;
$post_query = urlencode($packet) . "\r\n";
$fp = fsockopen($host, '80');
if ($fp) {
fputs($fp, "POST $path HTTP/1.0\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Content-length: ". strlen($post_query) ."\r\n\r\n");
fputs($fp, $post_query);
while (!feof($fp)) {
$line = fgets($fp, 10240);
if ($flag) {
$content .= $line;
} else {
$headers .= $line;
if (strlen(trim($line)) == 0) {
$flag = true;
}
}
}
fclose($fp);
}
return $content;
}
虽然这确实给了我正在调用的 URL 的返回值,但它这样做不正确,因为我收到一个错误,说它的格式不正确。我对 CURL 或其他方法都不是很熟悉,所以我不确定我做错了什么。
