PHP流式上传和表单上传（美图秀秀）

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。

01 <?php
02 /**
03  * Note:for octet-stream upload
04  * 这个是流式上传PHP文件
05  * Please be amended accordingly based on the actual situation
06  */
07 $post_input = 'php://input';
08 $save_path = dirname(__FILE__);
09 $postdata = file_get_contents($post_input);
10 if (isset($postdata) && strlen($postdata) > 0) {
11     $filename = $save_path . '/' . uniqid() . '.jpg';
12     $handle = fopen($filename, 'w+');
13     fwrite($handle, $postdata);
14     fclose($handle);
15     if (is_file($filename)) {
16         echo 'Image data save successed,file:' . $filename;
17         exit ();
18     } else {
19         die ('Image upload error!');
20     }
21 } else {
22     die ('Image data not detected!');
23 }

 

01 <?php
02 /**
03  * Note:for multipart/form-data upload
04  * 这个是标准表单上传PHP文件
05  * Please be amended accordingly based on the actual situation
06  */
07 if (!$_FILES['Filedata']) {
08     die ('Image data not detected!');

12         case 1 :

28 } else {
29     $img_data = $_FILES['Filedata']['tmp_name'];
30     $size = getimagesize($img_data);
31     $file_type = $size['mime'];
32     if (!in_array($file_type, array('image/jpg', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/gif'))) {

46             $extension = 'gif';
47             break;
48     }
49 }

51 if (!is_file($img_data)) {
52     die ('Image upload error!');
53 }
54
55 // 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)
56 $save_path = dirname(__FILE__);
57 $uinqid = uniqid();
58 $filename = $save_path . '/' . $uinqid . '.' . $extension;
59 $result = move_uploaded_file($img_data, $filename);
60 if (!$result || !is_file($filename)) {

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" 。
