Powershell Invoke-RestMethod：远程服务器返回错误：(413) 请求实体太大

Question

这是我提出的“无法将 JSON 数据摄取到 Azure 事件中心”问题的延续。

我编写了下面的 powershell 脚本来从 API 端点获取 JSON 数据，然后将这些数据在没有任何格式更改的情况下移动到 Azure 事件中心。 当我运行它时，我收到以下错误：

$url = "https://data.melbourne.vic.gov.au/resource/vh2v-4nfs"
$apptoken = "n8lQcUZROasdh9fSSMuV"

# 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

$resultsJSON = $results | ConvertTo-Json

#Write-Host $results

$method = "POST"
$URI = "https://EHNS.servicebus.windows.net/eh-streetparking/messages"
$signature = "SharedAccessSignature sr=EH.servicebus.windows.net%2feh-streetparking&sig=erTfoeVLiWrOk9aDsU%3d&se=1605994&skn=eh-sap-streetparking"


# API headers
$headers = @{
            "Authorization"=$signature;
#            "Content-Type"="application/json;type=entry;charset=utf-8";
            "Content-Type"="application/json";
            }


# create Request Body

# execute the Azure REST API

Invoke-RestMethod -Uri $URI -Method $method -Headers $headers -Body $resultsJSON

＃错误

Invoke-RestMethod : The remote server returned an error: (413) Request Entity Too Large.

如何解决此错误？ 在编写上述类型的脚本时，我可以采用什么更好的脚本语言和/或实践？
