uploadify实现七牛云存储 显示上传进度+页面显示,uploadify牛云

准备:

uploadify下载地址:

http://www.uploadify.com/download/

七牛 php-sdk开发指南:

http://developer.qiniu.com/docs/v6/sdk/php-sdk.html

php-sdk地址:

https://github.com/qiniu/php-sdk

开始:

 DEMO:

http://hxend.com/uploadif/

 

在七牛里面注册账号以后,成为标准用户

免费存储空间10GB
免费每月下载流量10GB
免费每月PUT/DELETE 10万次请求
免费每月GET 100万次请求

貌似是一个不错的福利。

成功注册后就会 账号页面 有ak 和sk key 可以在代码中使用。

下载好uploadify 后 把 七牛 php -sdk 文件包里面的内容放在 uploadify 里面

打开uploadify.php 文件  代码如下:

<?php
/*

*/

// Define a destination
$targetFolder = '/uploads'; // Relative to the root

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

if (!empty($_FILES) && $_POST['token'] == $verifyToken) {
	$tempFile = $_FILES['Filedata']['tmp_name'];
	$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
	$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
	
	// Validate the file type
	$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
	$fileParts = pathinfo($_FILES['Filedata']['name']);
	
	if (in_array($fileParts['extension'],$fileTypes)) {
		move_uploaded_file($tempFile,$targetFile);
		echo '1';
	} else {
		echo 'Invalid file type.';
	}
}
?>
Copy after login

  修改代码如下: 介绍参考代码内部.

<?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'])); //在这里修改生出随机图片名
    $fileTypes = array('jpg','jpeg','gif','png');  //限制上传的文件为图片 
    $fileParts = pathinfo($_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 = "hdimg";//空间名
        //截取原始文件后缀名
        $key1 = "Uploads/".$filename;
        $accessKey = ' '; //这里填写ak
        $secretKey = ' '; // 这里填写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://hdimg.qiniudn.com/".$key1; //前台使用回调函数的data参数接收  
    } else {
        echo 'Invalid file type.';
    }
}
Copy after login

  前台index.php修改为:前台调用 echo 输出的值data 进行操作。

			});

		});
	</script>
</body>

Copy after login

  对data 进行输入到页面 实现 当前页面显示。控制 #txtimg 的值为 输出的data值 即为 图片地址。

后期 如果需要 iframe 调用的话 可以把

document.getElementById('txtimg').src=data;  可以把data 传输到父页面 的 #txtimg 中。
Copy after login
parent.document.getElementById('txtimg').src=data;
Copy after login
