最近需要用http模拟表单提交，简单的数据提交倒是简单，如果要上传图片就要稍微做些变动了。下面分享一下，利用curl和fsockopen两种方法实现，我测试通过的例子。

发送请求的页面:fsocketupload.php

<?php/** * @author zhao jinhan * @email: xb_zjh@126.com * @url : www.icode100.com * @date : 2014年1月18日13:09:42 *  */header('Content-type:text/html; charset=utf-8');  //声明编码//模拟POST上传图片和数据//第一种方法：CURL$ch = curl_init();$url = 'http://www.test.localhost/fsocketget.php';$curlPost = array('sid'=>1,'file'=>'@D:/xampp/htdocs/www/www.test.localhost/images/adding.gif');curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POST, 1); //POST提交curl_setopt($ch, CURLOPT_POSTFIELDS,$curlPost);$data =curl_exec($ch);curl_close($ch);echo '<pre>';var_dump($data); //第二种方法：fsockopen方法上传 $arr_data = array('sid'=>1,'mid'=>2);  //普通参数$var_file='image';       //文件变量名$file_type='image/jpeg'; //文件类型$filepath = 'D:/xampp/htdocs/www/www.test.localhost/images/2.jpg'; //文件路径$filestring = @file_get_contents($filepath) or exit('not found file ( '.$filepath.' )'); //生成文件流$host = 'www.test.localhost';   //构造post请求的头$boundary = substr(md5(time()),8,16);  //分隔符$header  = "POST /fsocketget.php HTTP/1.1\r\n";//一般有post, get这两种$header .= "Host: {$host}\r\n";$header .= "Content-Type: multipart/form-data; boundary={$boundary}\r\n"; $data = "";//请求普通数据foreach($arr_data as $k=>$v){ $data .= "--{$boundary}\r\n"; $data .= "Content-Disposition: form-data; name=\"{$k}\"\r\n"; $data .= "\r\n{$v}\r\n"; $data .= "--{$boundary}\r\n";}//请求图片数据$filename = basename($filepath); //文件名$data .= "--{$boundary}\r\n";$data .= "Content-Disposition: form-data; name=\"$var_file\"; filename=\"$filename\"\r\n";$data .= "Content-Type: $file_type\r\n";  //\r\n不可少$data .= "\r\n$filestring\r\n";           //\r\n不可少$data .= "--{$boundary}\r\n";             //\r\n不可少$header .= "Content-Length: ".strlen($data)."\r\n\r\n";   //\r\n不可少 //发送post的数据$fp = fsockopen($host,80,$errno,$errstr,10) or exit($errstr."--->".$errno);fputs($fp,$header.$data); $inheader = 0;  //1去除请求包的头只显示页面的返回数据 0-保留头while (!feof($fp)) { $line = fgets($fp,1024); if ($inheader && ($line == "\n" || $line == "\r\n")) {  $inheader = 0; } if ($inheader == 0) {  echo $line; }} fclose($fp);

请求api页面：fsocketget.php

<?php/* 接收请求的API */if($_POST){ echo '<pre>'; print_r($_POST); print_r($_FILES);}else{ echo 'error';}
