API文檔

我們提供了一套兼容AmazonS3的RESTful API，可以使您更加自由地開發(fā)出靈活的功能

概述

新浪云存儲(chǔ)服務(wù)主要提供以下三類API：

  • Service操作
  • Bucket操作
  • Object操作

與此同時(shí)，為提高用戶使用的安全性，新浪云存儲(chǔ)服務(wù)還通過使用簽名來驗(yàn)證請求者的身份。

如需了解簽名算法的詳細(xì)信息，請參考《簽名算法》。

如需了解ACL的詳細(xì)信息，請參考《ACL》。

如涉及Bucket和Object的命名規(guī)劃，請參考《約束與限制》。

注意：以下接口中所使用的示例都是在需要使用簽名情況下；如果相關(guān)訪問資源已設(shè)置為可匿名（所有用戶）訪問，則可不帶簽名。

表單元素：

Name Description Required
AWSAccessKeyId 就是AccessKey，可以到控制臺(tái)獲取 Yes
key object上傳后的key（路徑），例如：angel/${filename}，變量${filename}將被自動(dòng)替換成被上傳文件的文件名；當(dāng)然也可以直接指定被上傳文件存儲(chǔ)在Sinastorage的文件名。如：angel/path/to/myfile.txt Yes
acl 文件的ACL：創(chuàng)建文件的同時(shí)，快速設(shè)置一個(gè)Canned-ACL。請參照：《ACL》 No
success_action_status 上傳成功后的響應(yīng)碼，通常設(shè)置為201 No
success_action_redirect 上傳成功后客戶端重定向的URL。 No
Policy 文件的策略，json格式字符串，并使用base64進(jìn)行編碼。后面詳細(xì)介紹 Yes
Signature 使用SecretKey簽名后的字符串。后面詳細(xì)介紹 Yes
file type=file的input表單 Yes
x-amz-meta-* 用戶可自定義文件屬性信息，讀取時(shí)原值返回。 No
Cache-Control 文件的緩存策略(例如：max-age=31536000)，讀取時(shí)原值返回。 No
Expires 文件在客戶端或?yàn)g覽器的緩存過期時(shí)間，允許客戶端在這個(gè)時(shí)間之前不去服務(wù)端檢查，讀取時(shí)原值返回。格式為：Sun, 29 Jul 2018 20:36:14 UTC No

Policy的構(gòu)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
        ]
    ]
}

以上示例的說明：

  • 上傳必須在”2014-04-10T08:55:34.000Z”之前。
  • 文件上傳到名為”my-bucket-name”的bucket。
  • starts-with：$key必須以”my_prefix/”開始 (Policy中”$key”前必須帶”$”)。若$key值為空，文件名前無前綴。
  • content-length-range：文件大小必須在指定范圍內(nèi)。
  • 最終將policy進(jìn)行base64編碼設(shè)置到表單Policy的value中。

Signature的構(gòu)建：

  • 用UTF-8對policy進(jìn)行編碼
  • 用Base64對UTF-8形式的policy進(jìn)行編碼
  • 用HMAC SHA-1和你的Secret Key將你的policy進(jìn)行轉(zhuǎn)換。最后進(jìn)行base64編碼。如：使用php時(shí)，base64_encode( hash_hmac( "sha1", $policy, $SECRETKEY, true ) );
  • 將最終的值設(shè)置到表單Signature的value中。

最終生成的html表單：

<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="file" name="file" />
    <input type="submit" value="上傳" />
</form>

注意事項(xiàng)：

  • POST請求后的uri只能是“/”
  • success_action_redirect：指定上傳成功后客戶端重定向的URL。
  • key：變量${filename}將被自動(dòng)替換成被上傳文件的文件名；當(dāng)然也可以直接指定被上傳文件存儲(chǔ)在Sinastorage的文件名。
