php+curl上传文件到远程服务器

一、window下安装php_curl支持

　　1.将PHP安装文件夹下的三个文件php_curl.dll(可能在ext文件夹中),libeay32.dll,ssleay32.dll 复制到 %windir%/system32下;
　　2.打开php.ini(可能在PHP环境的安装目录下，默认在c:\WINDOWS目录下)，将;extension=php_curl.dll头部的分号去掉;

　　3.重启php的服务(apache或者IIS)，如重启IIS，运行iisreset即可。

二、注意事项。

注意服务器文件夹的权限，

php.ini 里 upload_tmp_dir 设置一个全新的目录 也赋予Everyone 读写权限。

上传文件的目标目录也赋予Everyone 读写权限。

三、直接上代码

1、文件curlTest.php:

UpLoad:

0, 'message' => 'ok'); ini_set('upload_max_filesize', '20M'); ini_set('post_max_size', '20M'); ini_set('memory_limit', '128M'); //接收上传的远程地址 $url = isset($_POST['url']) ? trim($_POST['url']) : ''; $url ="www.123.com/k1/upload.php"; if (empty($url)) { $result['code'] = 40001; $result['message'] = 'url不能为空'; //Helper_Http::writeJson(200,$result); } $file = $_FILES['file']; print_r($_FILES); if ($file['error'] != 0) { $result['code'] = 40001; $result['message'] = '上传出错'; //Helper_Http::writeJson(200,$result); echo 1; } else { $filename = $file['name']; $tmpfile = $file['tmp_name']; $filetype = $file['type']; $data = upload_file($url, $filename, $tmpfile, $filetype); echo $data; print_r ($url); die; } } /** * curl上传文件 * * @param unknown $url * @param unknown $filename * @param unknown $path * @param unknown $type */ function upload_file($url,$filename,$path,$type){ echo 3; echo $path; //php 5.5以上的用法 if (class_exists('\CURLFile')) { $data = array('file' => new \CURLFile(realpath($path),$type,$filename)); } else { $data = array( 'file'=>'@'.realpath($path).";type=".$type.";filename=".$filename ); } echo 'data:'; print_R($data); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, true ); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $return_data = curl_exec($ch); curl_close($ch); echo $return_data; }?>

2、文件upload.php：

 "; print_r($_FILES);  $uploaddir = 'D:/temp/caches/'; $uploadfile = $uploaddir . basename($_FILES['file']['name']);  echo '
'; if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) { 	echo "File is valid, and was successfully uploaded.\n"; } else { 	echo "Possible file upload attack!\n"; }  echo 'Here is some more debugging info:'; ?>
