最近需要开发一个头像上传的功能，找了很多都需要授权的，后来找到了美图秀秀，功能非常好用。

{
$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!');
}
}

{

}

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" 。
