【汇总】异步POST数据【ajax，curl，sock】
整理下异步post表单的方法被调用的程序，http://127.0.0.1/form.php
<?phpif(!empty($_POST)) {print_r($_POST);} else {echo 'NO POST';}
1.curl方法
<?php$url = 'http://127.0.0.1/form.php';$post = 'key1=value1&key2=value2';$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $post);$data = curl_exec($ch);curl_close($ch);print_r($data);
2.sock方法
<?php$encoded = 'key1=value1&key2=value2';$url = 'http://127.0.0.1/form.php';$url = parse_url($url);if (!$url) return "couldn\'t parse url";if (!isset($url['port'])) $url['port'] = "";if (!isset($url['query'])) $url['query'] = "";$port = $url['port'] ? $url['port'] : 80;$fp = fsockopen($url['host'], $port, $errno, $errstr);if (!$fp) return "Failed to open socket to $url $port ERROR: $errno - $errstr";fputs($fp, sprintf("POST %s%s%s HTTP/1.0\n", $url['path'], $url['query'] ? "?" : "", $url['query']));fputs($fp, "Host: ". $url['host'] ."\n");fputs($fp, "Content-type: application/x-www-form-urlencoded\n");fputs($fp, "Content-length: " . strlen($encoded) . "\n");fputs($fp, "Connection: close\n\n");fputs($fp, $encoded . "\n");$results = ""; $inheader = 1;while(!feof($fp)) {$line = fgets($fp,1024);if ($inheader && ($line == "\n" || $line == "\r\n")) {$inheader = 0;} elseif(!$inheader) {$results .= $line;}}fclose($fp);print_r($results);
3.javascript的ajax，会把url暴露在客户端
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script><script>$(function(){ $.post('http://127.0.0.1/form.php', {'key1':'value1','key2':'value2'}, function(data){} );});</script>
