废话少说，直接上代码：
<?php /** * Note:for octet-stream upload * 这个是流式上传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 . 'https://www.jb51.net/' . uniqid() . '.jpg'; $handle = fopen($filename, 'w+'); fwrite($handle, $postdata); fclose($handle); if (is_file($filename)) { echo 'Image data save successed,file:' . $filename; exit (); } else { die ('Image upload error!'); } } else { die ('Image data not detected!'); }
<?php /** * Note:for multipart/form-data upload * 这个是标准表单上传PHP文件 * Please be amended accordingly based on the actual situation */ if (!$_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!'); } // 图片保存路径,默认保存在该代码所在目录(可根据实际需求修改保存路径) $save_path = dirname(__FILE__); $uinqid = uniqid(); $filename = $save_path . 'https://www.jb51.net/' . $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 ();
备注：美图秀秀提供两个上传接口供测试
一个是octet-stream方式上传，地址为：
另一个是multipart/form-data方式上传，地址为：
表单名称为"upload_file"。
