powershell - 无法将 JSON 流数据引入 Azure 事件中心

问题描述

我想将从 API 端点获得的 JSON 结果发布到 Azure 事件中心 $default 消费者组，但我收到以下错误：

Invoke-RestMethod : The remote server returned an error: (401) Unauthorized.
At H:\Users\User1 - scripts\get_mel_streetparking_data.ps1:34 char:1
+ Invoke-RestMethod -Uri $URI -Method $method -Headers $headers -Body $res ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-    RestMethod], WebException
    + FullyQualifiedErrorId :     WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

我编写了以下一段 powershell 脚本，其中以下一段 get 代码运行良好：

$url = "https://data.melbourne.vic.gov.au/resource/vh2v-4nfs"
$apptoken = "abcdasdadaaf"

# Set header to accept JSON
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Accept","application/json")
$headers.Add("X-App-Token",$apptoken)

$results = Invoke-RestMethod -Uri $url -Method get -Headers $headers

但下面的一段代码失败并出现上述错误：

$method = "POST"
$URI = "https://[servicebusNamespace].servicebus.windows.net/[eventHubPath]/messages"
$signature = "SharedAccessSignature sr=[servicebusNamespace].servicebus.windows.net%2feventhub-    streetparking&sig=%3dgZfDHEGN8lVEGgqu4N64TW70BLuSKARSKgMPeRByc%5d&se=604985&skn=RootManageSharedAccessKe"

# API headers
$headers = @{
        "Authorization"=$signature;
        "Content-Type"="application/json";
        }


# create Request Body
#$body = "$results"

# execute the Azure REST API
Invoke-RestMethod -Uri $URI -Method $method -Headers $headers -Body $results

我在以下代码的帮助下生成了 SAS 令牌：

[Reflection.Assembly]::LoadWithPartialName("System.Web")| out-null    
$URI="[servicebusNamespace].servicebus.windows.net/[eventHubPath]"
$Access_Policy_Name="RootManageSharedAccessKey"
$Access_Policy_Key="Root key value"
#Token expires now+3000
$Expires=([DateTimeOffset]::Now.ToUnixTimeSeconds())+3000
$SignatureString=[System.Web.HttpUtility]::UrlEncode($URI)+ "`n" + [string]$Expires
$HMAC = New-Object System.Security.Cryptography.HMACSHA256
$HMAC.key = [Text.Encoding]::ASCII.GetBytes($Access_Policy_Key)
$Signature = $HMAC.ComputeHash([Text.Encoding]::ASCII.GetBytes($SignatureString))
$Signature = [Convert]::ToBase64String($Signature)
$SASToken = "SharedAccessSignature sr=" + [System.Web.HttpUtility]::UrlEncode($URI) + "&sig=" +     [System.Web.HttpUtility]::UrlEncode($Signature) + "&se=" + $Expires + "&skn=" + $Access_Policy_Name
$SASToken

请帮助我为什么我看到未经授权的错误

解决方案

在 SAS 令牌生成之前我没有替换以下值是我的错。

$Access_Policy_Name="RootManageSharedAccessKey" $Access_Policy_Key="根密钥值"
