【Uploadify】远程上传图片到【七牛云存储】

1.下载Uploadify 版本3.2.1 

2.下载七牛SDK 解压后将 qiniu 文件夹copy到uploadify文件夹下

3.修改uploadify.php文件

<?php

$verifyToken = md5(\'unique_salt\' . $_POST[\'timestamp\']);

if (!empty($_FILES) && $_POST[\'token\'] == $verifyToken) {
    $tempFile = $_FILES[\'Filedata\'][\'tmp_name\'];
    //生成新的文件名 
    $filename = time().mt_rand(10,99).\'.\'.end(explode(\'.\', $_FILES[\'Filedata\'][\'name\']));
    
    $fileTypes = array(\'jpg\',\'jpeg\',\'gif\',\'png\');
    $fileParts = pathinfo($_FILES[\'Filedata\'][\'name\']);

    if (in_array($fileParts[\'extension\'],$fileTypes)) {
        //上传图片到云端 start
        require_once("qiniu/io.php");
        require_once("qiniu/rs.php");

        $bucket = "abc";//空间名
        //截取原始文件后缀名
        $key1 = "Uploads/".$filename;
        $accessKey = \'X3X89F2xQlca63vmIfNtxmqPkJ9TKHNKE-XYzPjH\'; //AK
        $secretKey = \'O90SCQPjeONRFb1Ka15L1GK8qndACuo0C2lehngV\'; //SK

        Qiniu_SetKeys($accessKey, $secretKey);
        $putPolicy = new Qiniu_RS_PutPolicy($bucket);
        $upToken = $putPolicy->Token(null);
        $putExtra = new Qiniu_PutExtra();
        $putExtra->Crc32 = 1;
        //$tempFile uploadify上传的临时文件路径
        list($ret, $err) = Qiniu_PutFile($upToken, $key1, $tempFile, $putExtra);
        //上传图片到云端 end

        //返回文件名给前台
        echo "http://abc.qiniudn.com/".$key1; //前台使用回调函数的data参数接收
    } else {
        echo \'Invalid file type.\';
    }
}

前台代码 上传一个文件并显示到IMG标签中

<table style="border:none;" >
                <tr>
                    <td><img width="100" height="100" id="timg"/></td>
                    <td width=100%>
                        <script src="__STATIC__/uploadify/jquery.uploadify.js" type="text/javascript"></script>
                        <link rel="stylesheet" type="text/css" href="__STATIC__/uploadify/uploadify.css">
                        <div id="queue"></div>
                        <input id="file_upload" name="file_upload" type="file" multiple="true">
                        <script type="text/javascript">
                        <?php $timestamp = time();?>
                        $(function() {
                            $(\'#file_upload\').uploadify({
                                \'formData\'     : {
                                    \'timestamp\' : \'<?php echo $timestamp;?>\',
                                    \'token\'     : \'<?php echo md5(\'unique_salt\' . $timestamp);?>\'
                                },
                                \'swf\'      : \'__STATIC__/uploadify/uploadify.swf\',
                                \'uploader\' : \'__STATIC__/uploadify/uploadify.php\',
                                \'onUploadSuccess\' : function(file,data,response) {
                                    $("#timg").attr("src",data);
                                    $("#txtimg").val(data);
                                }
                            });
                        });
                        </script>
                    </td>
                </tr>
            </table>
