SAE全称是Sina App Engine(简称SAE)是新浪研发中心推出的国内首个公有云计算平台,支持PHP,MySQL,Memcached,Mail,TaskQueue,RDC(关系型数据库集群)等服务,下面我们来看SAE的storage服务用法
今天终于弄懂了sae的storage怎么使用,这里是sae的storage的概述地址:
http://sae.sina.com.cn/doc/php/storage.html。
因为sae不支持文件权限设置,所有的代码文件都是不可数的,但是sae提供了特别好的一个分布式文件存储服务,用来存放持久文件,其实就是用来存放网站的素材文件,如图片，文件等等的,所以,当需要存储文件数据的时候,可以使用使用sae.
使用sae一共有两种方案.
官方提供的一种方案是:使用官方的storage类,直接可以进行文件操作,如存放文件,删除文件,修改文件等等.
官方API文档地址:http://apidoc.sinaapp.com/sae/SaeStorage.html
还有一种方法是我在sae的应用商店看到的,里面有一个合成的wordpress for sae,我们可以看到详细的代码,我现在将自己简单的测试代码贴到下面,只为实现storage,不适用于开发场景,代码如下:
class="brush:php;"><html>
<body>
<form action="" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
<?php
$domain = "test";
$upload_dir = "saestor://" . $domain . "/qiao1/2/3/4/5/";
if(!is_dir($upload_dir))
{
//mkdir($upload_dir , 0777);
}
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
}
if(move_uploaded_file($_FILES["file"]["tmp_name"],$upload_dir . $_FILES["file"]['name']))
{
echo 'ok';
}
//mkdir($upload_dir . 'qiao' , 0777);
我们可以直接使用move_uploaded_file函数将临时文件上传,要注意的是第二个参数$upload_dir=”saestor://” . $domain . “/” . $dir.
其中,$domain就是storage中创建的storage服务名称,$dir就是要存放的目录,如要将文件存放在saestor://mydomain/dir1/dir2/dir3/下,可以直接使用该url,而不需要使用mkdir函数进行创建,因为stotage已经将该目录自动进行了创建.
