美图秀秀web开放平台--PHP流式上传和表单上传示例分享

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 . '/' . 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 . '/' . $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：http://imgkaka.meitu.com/xiuxiu_web_pic_save.php
另一个是multipart/form-data方式上传，地址为：http://web.upload.meitu.com/image_upload.php
表单名称为"upload_file"。
