Powershell中的Azure API SharedKeyLite [英] Azure API SharedKeyLite in Powershell

问题描述

我正在尝试在Powershell中实现SharedKeyLite Authorization标头功能.这是要连接到Azure Tables REST API.我遗漏了一些原因，导致我不断收到错误消息:

I'm trying to implement a SharedKeyLite Authorization header function in powershell. This is to connect to Azure Tables REST API. I'm missing something cause I keep getting an error:

服务器认证失败 请求.请确保正确构成Authorization标头的值(包括签名).

Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

   function GenerateHeader($accountName, $accountKey, $action)
{
    $xmsdate = get-date
    $xmsdate = $xmsdate.ToUniversalTime()
    $xmsdate = $xmsdate.toString('r')
    $newLine = "`n";
    $message = $xmsdate + $newline + "/" + $accountname + "/" + $action;
    $hmacsha = New-Object System.Security.Cryptography.HMACSHA256
    $hmacsha.key = [Convert]::FromBase64String($accesskey)
    $signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($message))
    $signature = [Convert]::ToBase64String($signature)
    $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
    $headers.Add("x-ms-version", "2014-02-14")
    $headers.Add("x-ms-date", $xmsdate)
    $headers.Add("Authorization", "SharedKeyLite " + $accountName + ":" + $signature)

    return $headers
}

更新: 这是调用此函数的代码. $ action变量设置为URI字符串.

UPDATE: Here's code that calls this function. The $action variable is set to the URI string.

$uriString = "https://$StorageAccountName.table.core.windows.net/Tables"

$headers = GenerateHeader $StorageAccountName $StorageAccountKey "Tables"

Invoke-RestMethod -Uri $uriString -Method $method -Headers $headers -Body $body

这是它引发的错误.

Invoke-RestMethod:AuthenticationFailedServer对请求进行身份验证失败.确保 Authorization标头的值格式正确，包括 签名.

这是函数外部$ headers变量的示例输出...

Here's the Example output from the $headers variable outside the function...

Key   : x-ms-version
Value : 2014-02-14

Key   : x-ms-date
Value : Tue, 26 May 2015 19:30:20 GMT

Key   : Authorization
Value : SharedKeyLite <MyStorageName>:lf+ndqhi4OeJhIfLljugT0dfcLbqXDBHwrQJn9Q66HQ=

推荐答案

所以这最终是一个简单的编码错误:(

So this ended up being a simple coding error :(

我现在觉得发布此消息有点愚蠢，但是我要发布答案，因为在任何地方都无法在Powershell中找到适用于Azure的有效的Authorization构建器.这确实适用于Azure表...

I feel kinda silly posting this now, but I'm going to post an answer cause I couldn't find a working Authorization builder for Azure in Powershell anywhere. This one does work for Azure tables...

function GenerateHeader($accountName, $accountKey, $action)
{
    $xmsdate = get-date
    $xmsdate = $xmsdate.ToUniversalTime()
    $xmsdate = $xmsdate.toString('R')
    $newLine = "`n";
    $action = $action.ToLower()
    $message = $xmsdate + $newline + "/" + $accountname + "/" + $action;
    $hmacsha = New-Object System.Security.Cryptography.HMACSHA256
    $hmacsha.key = [Convert]::FromBase64String($accountKey)
    $signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($message))
    $signature = [Convert]::ToBase64String($signature)
    $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
    $headers.Add("Content-Type", "application/json")
    $headers.Add("x-ms-date", $xmsdate)
    $headers.Add("Authorization", "SharedKeyLite " + $accountName + ":" + $signature)

    return $headers
}
