PHP中使用CURL（一）
執行流程：
curl_init()初始化 -> curl_setopt()設置變量 -> curl_exec()獲取結果 -> curl_close()釋放句柄

對 post 提交的數據進行 http_build_query處理，然後再send出去，能實現更好的兼容性，更小的請求數據包。

PHP中使用CURL（四）
爲了安全，我們的web服務主機往往不能上網。維護的時候，也是通過跳板機，ssh登錄後去操作。有時候我們的程序需要訪問外網。比如需要調用外網其他程序的某個接口。這時可以通過PHP的CURL函數的CURLOPT_HTTPHEADER來配置設置host訪問。

{ if (!empty($_SERVER["HTTP_CLIENT_IP"])) $ip = $_SERVER["HTTP_CLIENT_IP"]; else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) $ip = $_SERVER["HTTP_X_FORWARDED_FOR"]; else if (!empty($_SERVER["REMOTE_ADDR"])) $ip = $_SERVER["REMOTE_ADDR"]; else $ip = "err"; return $ip;}echo "IP:

getClientIp() . "";//IPecho "referer:

注：這個僞造建立在對方不對proxy ip還有remote_addr同時封禁的效果上。
PHP中使用CURL（六）
curl常用的幾個例子
1、抓取無訪問控制文件
1 <?php 2 $ch = curl_init(); 3 curl_setopt($ch, CURLOPT_URL, "http://localhost/mytest/phpinfo.php"); 4 curl_setopt($ch, CURLOPT_HEADER, false); 5 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //如果把這行註釋掉的話，就會直接輸出 6 $result=curl_exec($ch); 7 curl_close($ch); 8 ?>
2、使用代理進行抓取
<?php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://blog.snsgou.com"); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE); curl_setopt($ch, CURLOPT_PROXY, 125.21.23.6:8080); //url_setopt($ch, CURLOPT_PROXYUSERPWD, 'user:password');如果要密碼的話，加上這個 $result=curl_exec($ch); curl_close($ch); ?>
3、post數據後，抓取數據
<?php $ch = curl_init(); $data = array('name' => 'test', 'sex' => 1);//array(1) curl_setopt($ch, CURLOPT_URL, 'http://localhost/mytest/curl/userinfo.php'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_exec($ch); ?>
4、抓取一些有頁面訪問控制的頁面
<?php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://club-china"); curl_setopt($ch, CURLOPT_USERPWD, '[username]:[password]');//破解頁面訪問控制 curl_setopt($ch, CURLOPT_HTTPGET, 1); curl_setopt($ch, CURLOPT_REFERER, "http://club-china"); curl_setopt($ch, CURLOPT_HEADER, 0); $result = curl_exec($ch); curl_close($ch); ?>
5、模擬登錄
<?php function checkLogin($user, $password){ if (empty($user) || empty($password)){ return false; } $ch = curl_init(); curl_setopt($ch, CURLOPT_REFERER, "http://mail.sina.com.cn/index.html"); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERAGENT, USERAGENT); curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIEJAR); curl_setopt($ch, CURLOPT_TIMEOUT, TIMEOUT); curl_setopt($ch, CURLOPT_URL, "http://mail.sina.com.cn/cgi-bin/login.cgi"); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, "&logintype=uid&u=" . urlencode($user) . "&psw=" . $password); $contents = curl_exec($ch); curl_close($ch); if (!preg_match("/Location: (.*)\\/cgi\\/index\\.php\\?check_time=(.*)\n/", $contents, $matches)){ return false; }else{ return true; } } define("USERAGENT", $_SERVER['HTTP_USER_AGENT']); define("COOKIEJAR", tempnam("c:\windwos\temp", "cookie")); define("TIMEOUT", 500); echo checkLogin("username", "password"); ?>
6、文件上傳
<?php /** * @param string $target_url 上傳目標地址 * @param string $filename 上傳文件路徑 * @param string $form_name 表單名稱 */ function curlUploadFile($target_url, $filename, $form_name) { $upload_file = new CURLFile($filename); $post_data = array( $form_name => $upload_file ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $target_url); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($ch); curl_close($ch); } $target_url = 'http://www.codean.net/notFound/test.php'; $filename = realpath("C:/Users/HelloWorld/Desktop/Images/1.jpg"); $form_name = 'file'; // 接收端使用$_FILES接受 curlUploadFile($target_url, $filename, $form_name); ?>
7、文件流上傳
/* * 第三種寫法，使用PHP流發送 * @param string $target_url 上傳目標地址 */ function curlUploadFile($target_url) { $fh = fopen('php://temp', 'rw+'); $string = 'Hello World'; fwrite($fh, $string); rewind($fh); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $target_url); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 2); curl_setopt($ch, CURLOPT_PUT, true); curl_setopt($ch, CURLOPT_INFILE, $fh); curl_setopt($ch, CURLOPT_INFILESIZE, strlen($string)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); curl_close($ch); } $target_url = 'http://www.codean.net/notFound/test.php'; curlUploadFile($target_url); // 接收端取出流文件並保存 $putdata = fopen('php://input', 'r'); $fp = fopen('test.txt', 'w'); while ($data = fread($putdata, 1024)) { fwrite($fp, $data); } fclose($fp); fclose($putdata);
