Question

我在Azure中很安静，我正在尝试根据documentation实施Put Block List操作。以下是我上传文件的步骤

从本地文件夹中读取文件
使用Put block操作上传它。它取得了成功。
然后我用 Get Block List查看我的块是否上传以及我能看到的回复

<BlockList><CommittedBlocks /><UncommittedBlocks><Block><Name>MDAwMDAwMDAwMA==</Name><Size>17</Size></Block></UncommittedBlocks></BlockList>

我有一个标识为uncommited的{{1}}块。

最后我使用MDAwMDAwMDAwMA==提交blob。在这里，我收到错误代码403＆＃34; Forbidden＆＃34;。

我的签名如下

Put Block List

这是uri

"PUT\n

/storagekaren/dbstore/ddd.txt\ncomp:blocklist"

请求内容

https://storagekaren.blob.core.windows.net/dbstore/ddd.txt?comp=blocklist

使用此方法计算authorizationHeader

"<?xml version=\"1.0\" encoding=\"utf-8\"? 
>\r\n<BlockList>\r\n<Uncommitted>MDAwMDAwMDAwMA==</Uncommitted> 
</BlockList>\r\n"

这是我的HttpClient对象发出请求

public static String CreateAuthorizationHeader(String canonicalizedString)
    {
        string signature;

        using (var hmacSha256 = new         
HMACSHA256(Convert.FromBase64String(STORAGE_ACCOUNT_KEY)))
        {
            var dataToHmac = Encoding.UTF8.GetBytes(canonicalizedString);
            signature = 
Convert.ToBase64String(hmacSha256.ComputeHash(dataToHmac));
        }

        var authorizationHeader = String.Format(
            CultureInfo.InvariantCulture,
            "{0} {1}:{2}",
            "SharedKey",
            ACCOUNT_NAME,
            signature
        );

        return authorizationHeader;
    }

"SharedKey storagekaren:eIHacFz/PWypTWg6SN/4BOuqlCLVLctABhi6Ay7TYiA="

以下是有错误的回复

{System.Net.Http.HttpClient}
    BaseAddress: null
    DefaultRequestHeaders: {x-ms-date: Tue, 15 May 2018 11:07:51 GMT

}
    MaxResponseContentBufferSize: 2147483647
    Timeout: {01:00:00}

请帮助我理解我做错了什么？

基本上问题来了，因为HttpClient正在为text/plain标头添加Content-Type，而你为此传递一个空字符串。如果您将签名字符串更改为包含内容类型标题，我相信您不应该收到此错误。基本上，您的签名字符串应如下所示：

"PUT\n
\n
\n
110\n
\n
text/plain\n
\n
\n
\n
\n
\n
