我正在为Azure存储帐户(在这种情况下为表格)建立查询。我尝试接收过去一天的最后一个日志条目。
在存储查询构建器中,过滤器如下所示:
{
"filter": [
{
"id": "{ID}",
"andOr": "And",
"field": "TIMESTAMP",
"type": "DateTime",
"operator": ">=",
"value": "datetime'2019-11-18T10:08:41.296Z'",
"timeValue": "Last 24 hours",
"timestampType": "time",
"customTimestamp": {
"lastNumber": 7,
"lastTimeUnit": "Days"
},
"isLocal": true
}
],
"select": null,
"group": {
"id": "{ID}",
"children": [
"{CHILD}"
]
},
"top": null,
"filterType": "Query Builder",
"fileVersion": 0.2
}
此查询返回前一天的所有条目。 我试图在Azure REST API调用中使用此筛选器。在这样的Powershell函数中:
function GetTableEntityAll($TableName) {
$version = "2017-04-17"
$resource = "$tableName()"
$DST = [DateTime]::Today.AddDays(-1)
$table_url = "https://$storageAccount.table.core.windows.net/$resource"+ '?$filter=Timestamp gt datetime' + "'"+ $DST.ToString("s") + "'"
write-host $table_url
$GMTTime = (Get-Date).ToUniversalTime().toString('R')
$stringToSign = "$GMTTime`n/$storageAccount/$resource"
$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' = $GMTTime
Authorization = "SharedKeyLite " + $storageAccount + ":" + $signature
"x-ms-version" = $version
Accept = "application/json;odata=fullmetadata"
}
$item = Invoke-RestMethod -Method GET -Uri $table_url -Headers $headers -ContentType application/json
return $item.value
}
由此生成的URL是:
https://{Accountname}.table.core.windows.net/{Tablename}()?$filter=Timestamp gt datetime'2019-11-18T00:00:00'
这不返回任何记录。我也尝试对URL进行编码,但这也不起作用。如果我将日期时间更改为2016,则会收到前几条记录。

有什么想法吗?
