# API文档
# 概述
新浪云存储服务主要提供以下三类API:
- Service操作
- Bucket操作
- Object操作
与此同时,为提高用户使用的安全性,新浪云存储服务还通过使用签名来验证请求者的身份。
如需了解签名算法的详细信息,请参考《签名算法》。
如需了解ACL的详细信息,请参考《ACL》。
如涉及Bucket和Object的命名规划,请参考《约束与限制》。
关于签名说明
以下接口中所使用的示例都是在需要使用签名情况下;如果相关访问资源已设置为可匿名(所有用户)访问,则可不带签名。

join/personalfiles/myphoto.jpg
join/readme.txt
join/userlist.txt
join/zero.txt
mary/personalfiles/mary.jpg
mary/readme.txt

Authorization: <authorization string> #请参照《签名算法》
返回为:
Contents:
join/mailaddresss.txt
join/mycodelist.txt
join/personalfiles/connects.docx

# 表单字段说明
字段 | 说明 | 是否必填 |
---|---|---|
AWSAccessKeyId | 就是AccessKey,可以到控制台获取 | 是 |
key | object上传后的key(路径),例如:angel/${filename},变量${filename}将被自动替换成被上传文件的文件名;当然也可以直接指定被上传文件存储在Sinastorage的文件名。如:angel/path/to/myfile.txt | 是 |
acl | 文件的ACL:创建文件的同时,快速设置一个Canned-ACL。请参照:《ACL》 | 否 |
success_action_status | 上传成功后的响应码,通常设置为201 | 否 |
success_action_redirect | 上传成功后客户端重定向的URL。 | 否 |
Policy | 文件的策略,json格式字符串,并使用base64进行编码。后面详细介绍 | 是 |
Signature | 使用SecretKey签名后的字符串。后面详细介绍 | 是 |
file | type=file的input表单 | 是 |
x-amz-meta-* | 用户可自定义文件属性信息,读取时原值返回。 | 否 |
Cache-Control | 文件的缓存策略(例如:max-age=31536000),读取时原值返回。 | 否 |

# Policy的构建
{
"expiration": "2014-04-10T08:55:34.000Z",
"conditions": [
{
"bucket": "my-bucket-name"
},
{
"acl": "private"
},
[
"starts-with", "$key", "my_prefix/"
],
[
"content-length-range", 0, 52428800
]
]
}
以上示例的说明:
- 上传必须在
2014-04-10T08:55:34.000Z
之前 - 文件上传到名为
my-bucket-name
的bucket - starts-with:$key必须以
my_prefix/
开始 (Policy中$key
前必须带$
)。若$key
值为空,文件名前无前缀 - content-length-range:文件大小必须在指定范围内
- 最终将policy进行base64编码设置到表单Policy的value中
Signature的构建:
- 用UTF-8对policy进行编码
- 用Base64对UTF-8形式的policy进行编码
- 用HMAC SHA-1和你的Secret Key将你的policy进行转换。最后进行base64编码。如:使用php时,
base64_encode( hash_hmac( "sha1", $policy, $SECRETKEY, true ) );
- 将最终的值设置到表单Signature的value中。
最终生成的html表单样例:
<form method="post" action="http://my-bucket.sinacloud.net/" enctype="multipart/form-data">
<input type="hidden" name="AWSAccessKeyId" value="您的accesskey" />
<input type="hidden" name="key" value="my_prefix/${filename}" />
<input type="hidden" name="acl" value="private" />
<input type="hidden" name="success_action_status" value="201" />
<input type="hidden" name="Policy" value="eyJleHBpcmF0aW9uIjoiMjAxNC0wNC0xMFQwOToxNzozMC4wMDBaIiwiY29uZGl0aW9ucyI6W3siYnVja2V0IjoiY2xvdWQxMjMqwqwsdifsdGFydHMtd2l0aCIsIiRrZXkiLCJteWZpbGVzLyJdLFsic3RhcnRzLXdpdGgiLCIkQ29udGVudC1UeXBlIiwiIl0sWyJzdGFydHMtd2l0aCIsIiRDb250ZW50LURpc3Bvc2l0aW9uIiwiIl0seyJ1aWQiOiIxMjMifSxbImNvbnRlbnQtbGVuZ3RoLXJhbmdlIiwwLDUyNDI4ODAwXV19" />
<input type="hidden" name="Signature" value="HnOSk3kfx5LFtn4CIiFcSglQUXc=" />
<input type="file" name="file" />
<input type="submit" value="上传" />
</form>
注意事项
- POST请求后的uri只能是
/
- success_action_redirect:指定上传成功后客户端重定向的URL。
- key:变量
${filename}
将被自动替换成被上传文件的文件名;当然也可以直接指定被上传文件存储在Sinastorage的文件名。
