新浪云存储SCS

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》。

注意：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。

应用举例：

假设某Bucket下有如下文件(为方便说明，没有显示为json格式，仅表现其中的一些有用信息，以下同)：

join/mailaddresss.txt
join/mycodelist.txt
join/personalfiles/connects.docx
join/personalfiles/myphoto.jpg
join/readme.txt
join/userlist.txt
join/zero.txt
mary/personalfiles/mary.jpg
mary/readme.txt
sai/readme.txt

使用prefix指定以join/为开头的文件：

GET /?prefix=join/&formatter=json HTTP/1.1
Host: <Your-Bucket-Name>.sinacloud.net
Date: <date>
Authorization: <authorization string> #请参照《签名算法》

Contents:
    join/mailaddresss.txt
    join/mycodelist.txt
    join/personalfiles/connects.docx
    join/personalfiles/myphoto.jpg
    join/readme.txt
    join/userlist.txt
    join/zero.txt

使用delimiter指定折叠方式为‘/’：

GET /?delimiter=/&formatter=json HTTP/1.1
Host: <Your-Bucket-Name>.sinacloud.net
Date: <date>
Authorization: <authorization string> #请参照《签名算法》

Contents:

CommonPrefix:
    join
    mary
    sai

使用prefix指定以join/为开头的文件，同时使用delimiter指定折叠方式为‘/’：

GET /?prefix=join/&delimiter=/&formatter=json HTTP/1.1
Host: <Your-Bucket-Name>.sinacloud.net
Date: <date>
Authorization: <authorization string> #请参照《签名算法》

Contents:
    join/mailaddresss.txt
    join/mycodelist.txt
    join/readme.txt
    join/userlist.txt
    join/zero.txt
CommonPrefix:
    join/personalfiles/

使用max-keys做最大值列表长度限制：

GET /?prefix=join/&delimiter=/&max-keys=4&formatter=json HTTP/1.1
Host: <Your-Bucket-Name>.sinacloud.net
Date: <date>
Authorization: <authorization string> #请参照《签名算法》

IsTruncated : true
Next-Marker : join/userlist.txt
Contents:
    join/mailaddresss.txt
    join/mycodelist.txt
    join/readme.txt
CommonPrefix:
    join/personalfiles/

使用marker继续获得之前的列操作的后续结果：

GET /?prefix=join/&delimiter=/&max-keys=4&marker=join/userlist.txt&formatter=json HTTP/1.1
Host: <Your-Bucket-Name>.sinacloud.net
Date: <date>
Authorization: <authorization string> #请参照《签名算法》

IsTruncated : false
Contents:
    join/userlist.txt
    join/zero.txt

表单元素：

Name	Description	Required
AWSAccessKeyId	就是AccessKey，可以到控制台获取	Yes
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	Yes
acl	文件的ACL：创建文件的同时，快速设置一个Canned-ACL。请参照：《ACL》	No
success_action_status	上传成功后的响应码，通常设置为201	No
success_action_redirect	上传成功后客户端重定向的URL。	No
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	Yes
Signature	使用SecretKey签名后的字符串。后面详细介绍	Yes
file	type=file的input表单	Yes
x-amz-meta-*	用户可自定义文件属性信息，读取时原值返回。	No
Cache-Control	文件的缓存策略(例如：max-age=31536000)，读取时原值返回。	No
Expires	文件在客户端或浏览器的缓存过期时间，允许客户端在这个时间之前不去服务端检查，读取时原值返回。格式为：Sun, 29 Jul 2018 20:36:14 UTC	No

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：

<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。
