上午终于把IF接口设计好了，加密与解密认证通过客户认定。主要通过三个参数来识别验证。
下面将用到向远程服务器提交参数，并获取结果来处理。
先收集几种远程执行URL并取得结果的方法。晚上有时间就完成这个功能。
方法1: 用file_get_contents 以get方式获取内容

<?php $url='http://www.zhoz.com/'; $html = file_get_contents($url); //print_r($http_response_header); ec($html); printhr();    printarr($http_response_header); printhr();    ?>
  
方法2: Array
我觉得这个方法比较常用。

<?php $fp = fopen($url, 'r'); printarr(stream_get_meta_data($fp)); printhr(); while(!feof($fp)) {    $result .= fgets($fp, 1024); } echo "url body:    $result"; printhr(); fclose($fp); ?>

方法3：Array


<?php $data = array ('foo' => 'bar'); $data = http_build_query($data); $opts = array ( 'http' => array ( 'method' => 'POST', 'header'=> "Content-type: application/x-www-form-urlencoded\r\n" . "Content-Length: " . strlen($data) . "\r\n", 'content' => $data ), ); $context = stream_context_create($opts); $html = file_get_contents('http://localhost/e/admin/test.html', false, $context); echo $html; ?>

方法4：Array

<?php function get_url ($url,$cookie=false) { $url = parse_url($url); $query = $url[path]."?".$url[query]; ec("Query:".$query); $fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30); if (!$fp) {        return false; } else {        $request = "GET $query HTTP/1.1\r\n";        $request .= "Host: $url[host]\r\n";        $request .= "Connection: Close\r\n";        if($cookie) $request.="Cookie:   $cookie\n";        $request.="\r\n";        fwrite($fp,$request);        while(!@feof($fp)) {          $result .= @fgets($fp, 1024);        }        fclose($fp);        return $result; } } //获取url的html部分，去掉header function GetUrlHTML($url,$cookie=false) {     $rowdata = get_url($url,$cookie);     if($rowdata)     {         $body= stristr($rowdata,"\r\n\r\n");         $body=substr($body,4,strlen($body));         return $body;     }          return false; } ?>

方法5：Array

<?php function HTTP_Post($URL,$data,$cookie, $referrer="") { // parsing the given URL $URL_Info=parse_url($URL); // Building referrer if($referrer=="") // if not given use this script as referrer $referrer="111"; // making string from $data foreach($data as $key=>$value) $values[]="$key=".urlencode($value); $data_string=implode("&",$values); // Find out which port is needed - if not given use standard (=80) if(!isset($URL_Info["port"])) $URL_Info["port"]=80; // building POST-request: $request.="POST ".$URL_Info["path"]." HTTP/1.1\n"; $request.="Host: ".$URL_Info["host"]."\n"; $request.="Referer: $referer\n"; $request.="Content-type: application/x-www-form-urlencoded\n"; $request.="Content-length: ".strlen($data_string)."\n"; $request.="Connection: close\n"; $request.="Cookie:   $cookie\n"; $request.="\n"; $request.=$data_string."\n"; $fp = fsockopen($URL_Info["host"],$URL_Info["port"]); fputs($fp, $request); while(!feof($fp)) {        $result .= fgets($fp, 1024); } fclose($fp); return $result; } printhr(); ?>

方法6:Array

<?php $ch = curl_init(); $timeout = 5; curl_setopt ($ch, CURLOPT_URL, 'http://www.zhoz.com/'); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents; ?>
关于curl库：
curl官方网站http://curl.haxx.se/
curl 是使用URL语法的传送文件工具，支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL证书、HTTP POST、HTTP PUT 、FTP 上传，kerberos、基于HTT格式的上传、代理、cookie、用户＋口令证明、文件传送恢复、http代理通道和大量其他有用的技巧，最近热门的SNS中也用到这个方法，取得MSN上的好友列表等，应用还是挺多的。只不过需要组件支持，开启方法我的技术圈中有说明：http://o.zhoz.com/

<?php function printarr(array $arr) {     echo "<br> Row field count: ".count($arr)."<br>";     foreach($arr as $key=>$value)     {                      echo "$key=$value    <br>";     } } ?>
