如何在Azure文件共享列表REST API中使用maxresult和nextmark参数

Question

我正在尝试使用list Share REST API列出存储帐户中的所有共享(https://learn.microsoft.com/en-us/rest/api/storageservices/list-shares#Authorization)。但我对带有标记参数的Authorization标头有问题。我想问题出在$nextMarkerIf语句下的$stringsign变量。

$StorageAccount = "XXXXX"
$Accesskey = "XXXXXXX==";
$Version="2019-12-12"
$SharePropObj = @()
$date = [System.DateTime]::UtcNow.ToString("R",[Globalization.CultureInfo]::InvariantCulture)
$stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`n"+
"x-ms-date:$date`nx-ms-version:$version`n" +
"/$storageAccount/`ncomp:list`nmaxresults:5000" 
$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Convert]::FromBase64String($accesskey)
$signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($stringToSign))
$signature = [Convert]::ToBase64String($signature)
$headers=@{"x-ms-date"=$date;
"x-ms-version"= $version;
"Authorization"= "SharedKey $($storageAccount):$signature";
"ContentType"="application/xml"
}
$URI = "https://$storageAccount.file.core.windows.net/?comp=list&maxresults=5000"
Try {
$response = Invoke-RestMethod $URI -Method 'GET' -Headers $headers

}Catch {
"Error Occurred. $_.exception.message"
}
If ($response){
[xml]$Result = [xml]($response -replace '',"")

$Shareprops = $Result.EnumerationResults.ChildNodes.share | %{
$share = $_.Name
$Quota = $_.properties.Quota
"$share,$Quota"
}
$SharePropCol = "ShareName,Quota"
$SharePropObj += @($SharePropCol,($Shareprops | where {$_.length -gt 1})) | ConvertFrom-Csv -Delimiter ","
$SharePropObj

$NextMarker = $Result.EnumerationResults.NextMarker.Split("/")[-1]
if ($NextMarker){
#Write-Error "Data for some shares are missed"
#$SharePropObj = @()
$date = [System.DateTime]::UtcNow.ToString("R",[Globalization.CultureInfo]::InvariantCulture)
$stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`n"+
"x-ms-date:$date`nx-ms-version:$version`n" +
"/$storageAccount/`ncomp:list`nmaxresults:5000`nmarker:$NextMarker" 
$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Convert]::FromBase64String($accesskey)
$signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($stringToSign))
$signature = [Convert]::ToBase64String($signature)
$headers=@{"x-ms-date"=$date;
"x-ms-version"= $version;
"Authorization"= "SharedKey $($storageAccount):$signature";
"ContentType"="application/xml"
}
$URI = "https://$storageAccount.file.core.windows.net/?comp=list&maxresults=5000&marker=$NextMarker"
$response1 = Invoke-RestMethod $URI -Method 'GET' -Headers $headers
[xml]$Result = [xml]($response1 -replace '',"")

$Shareprops = $Result.EnumerationResults.ChildNodes.share | %{
$share = $_.Name
$Quota = $_.properties.Quota
"$share,$Quota"
}

$SharePropCol = "ShareName,Quota"
$SharePropObj += @($SharePropCol,($Shareprops | where {$_.length -gt 1})) | ConvertFrom-Csv -Delimiter ","
$SharePropObj




}
}

请更改您的以下代码：

1.对于$NextMarker，请更改这行代码

$NextMarker = $Result.EnumerationResults.NextMarker.Split("/")[-1]

至

$NextMarker = "/$storageAccount/" + $Result.EnumerationResults.NextMarker.Split("/")[-1]

2. 在if ($NextMarker){}代码块中->对于$stringToSign，请将marker:$NextMarker放在maxresults:5000之前。更改如下：

   $stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`n"+
   "x-ms-date:$date`nx-ms-version:$version`n" +
   "/$storageAccount/`ncomp:list`nmarker:$NextMarker`nmaxresults:5000".
   

3.在if ($NextMarker){}代码块中->对于$URI，也请将marker=$NextMarker放置在maxresults=5000之前。更改如下：

$URI = "https://$storageAccount.file.core.windows.net/?comp=list&marker=$NextMarker&maxresults=5000"

我已经测试过了，效果很好。如果你还有问题，请告诉我。
