廢話少說，直接上代碼：

<?php/** * Note:for octet-stream upload * 這個是流式上傳PHP文件 * Please be amended accordingly based on the actual situation */$post_input = 'php://input';$save_path = dirname(__FILE__);$postdata = file_get_contents($post_input);if (isset($postdata) && strlen($postdata) > 0) { $filename = $save_path . 'http://www.49028c.com/' . uniqid() . '.jpg'; $handle = fopen($filename, 'w+'); fwrite($handle, $postdata); fclose($handle); if (is_file($filename)) { echo 'Image data save successed,file:' . $filename; exit (); } else { die ('Image upload error!'); }} else { die ('Image data not detected!');}

<?php/** * Note:for multipart/form-data upload * 這個是標準表單上傳PHP文件 * Please be amended accordingly based on the actual situation */if (!$_FILES['Filedata']) { die ('Image data not detected!');}if ($_FILES['Filedata']['error'] > 0) { switch ($_FILES ['Filedata'] ['error']) { case 1 :$error_log = 'The file is bigger than this PHP installation allows';break; case 2 :$error_log = 'The file is bigger than this form allows';break; case 3 :$error_log = 'Only part of the file was uploaded';break; case 4 :$error_log = 'No file was uploaded';break; default :break; } die ('upload error:' . $error_log);} else { $img_data = $_FILES['Filedata']['tmp_name']; $size = getimagesize($img_data); $file_type = $size['mime']; if (!in_array($file_type, array('image/jpg', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/gif'))) { $error_log = 'only allow jpg,png,gif'; die ('upload error:' . $error_log); } switch ($file_type) { case 'image/jpg' : case 'image/jpeg' : case 'image/pjpeg' :$extension = 'jpg';break; case 'image/png' :$extension = 'png';break; case 'image/gif' :$extension = 'gif';break; }}if (!is_file($img_data)) { die ('Image upload error!');}// 圖片保存路徑,默認保存在該代碼所在目錄(可根據實際需求修改保存路徑)$save_path = dirname(__FILE__);$uinqid = uniqid();$filename = $save_path . 'http://www.49028c.com/' . $uinqid . '.' . $extension;$result = move_uploaded_file($img_data, $filename);if (!$result || !is_file($filename)) { die ('Image upload error!');}echo 'Image data save successed,file:' . $filename;exit ();

備注：美圖秀秀提供兩個上傳接口供測試
一個是octet-stream方式上傳，地址為：
另一個是multipart/form-data方式上傳，地址為：
表單名稱為"upload_file"。
