#Crab
提供图片/文件上传接口，动态生成可控制尺寸的缩略图。
##图片/文件上传
代码示例：
```
<?php
    // 确保$file为绝对路径
    $file = dirname(__FILE__).'/bg.jpg'; // 图片
    //$file = dirname(__FILE__).'/a.txt'; // 其他文件

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, 'http://crab.oschina.mopaasapp.com/');
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, ['file' => '@'.$file]);
    $response = curl_exec($curl);
    curl_close($curl);
    $result = json_decode($response);
    if($result && $result->status == 1) { // 上传成功
        print_r($result->data); // 获取文件存储地址url
    } else {
        throw new Exception($response);
    }
```    
##获取上传的图片缩略图
如获得的url为：
```
http://crab.oschina.mopaasapp.com/image/origin/2015/12/11/3d3648e8c205f7662ff16eacd7ba4816.jpeg
```
![输入图片说明](http://crab.oschina.mopaasapp.com/image/origin/2015/12/11/3d3648e8c205f7662ff16eacd7ba4816.jpeg?width=400 "原图")

在url后附加width和height参数，改变它们的值，即可控制生成缩略图的大小：
```
http://crab.oschina.mopaasapp.com/image/origin/2015/12/11/3d3648e8c205f7662ff16eacd7ba4816.jpeg?width=300&height=150
```
