【问题描述】：

我一直在编写一个 powershell 脚本来使用 Graph API 来设置邮箱规则。基本上我遵循了这个guide 我可以按照指南创建文件夹，但是当我尝试编辑脚本并用这个info 替换正文以创建消息规则时它失败了。我正在努力找出原因。有人知道我可能会出错的地方吗？

    ## Details for mailboxes and folders needed. Obviously you can get these as parameters if need be.
    For AdHoc code I use "Get-Clipboard" quite often. Here a fixed array as something to start with.

$Mailboxes = @("mailbox")

## Before next step aquire access token, if you need help this blog has a great example https://adamtheautomator.com/microsoft-graph-api-powershell/. For simplicity, I have used here an application secret.

# Define AppId, secret and scope, your tenant name and endpoint URL
$AppId = "ID"
$AppSecret = "Secret"
$Scope = "https://graph.microsoft.com/.default"
$TenantName = "name"

$Url = "https://login.microsoftonline.com/$TenantName/oauth2/v2.0/token"

# Add System.Web for urlencode
Add-Type -AssemblyName System.Web

# Create body
$Body = @{
    client_id = $AppId
    client_secret = $AppSecret
    scope = $Scope
    grant_type = 'client_credentials'
}

# Splat the parameters for Invoke-Restmethod for cleaner code
$PostSplat = @{
    ContentType = 'application/x-www-form-urlencoded'
    Method = 'POST'
    # Create string by joining bodylist with '&'
    Body = $Body
    Uri = $Url
}

# Request the token!
$Request = Invoke-RestMethod @PostSplat

# Create header
$Header = @{
    Authorization = "$($Request.token_type) $($Request.access_token)"
}

## Thanks, now we have token ready for use. Lets use GRAPH's mailFolders API

## Loop through mailbxoes

foreach($mailbox in $Mailboxes) {

    $Uri = "https://graph.microsoft.com/v1.0/users/$mailbox/mailFolders/inbox/messageRules"


$Body = @"
{      
    "displayName": "Test",      
    "sequence": 2,      
    "isEnabled": true,          
    "conditions": {
        "importance": [
          "low"       
        ]
     },
     "actions": {
        "copyToFolder": [
          "Low Priority"       
        ],
        "stopProcessingRules": true
     }    
}
"@

   $NewRule = Invoke-RestMethod -Uri $Uri -Headers $Header -Method Post -Body $Body -ContentType "application/json"
   
   

}

您收到的错误信息是什么？
我得到的错误是：Invoke-RestMethod：远程服务器返回错误：（400）错误请求。在 C:\Ry Files\Powershell\mailrule.ps1:67 char:15 + ... $NewRule = Invoke-RestMethod -Uri $Uri -Headers $Header -Method Post ... + ~~~~~~~~~ ～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

【解决方案1】：

您的帖子语法不正确，重要性或copyToFolder都不是数组，文件夹也应该是文件夹的ID而不是名称。所以一个成功的帖子应该是这样的

{      
            "displayName": "Test",      
            "sequence": 2,      
            "isEnabled": true,          
            "conditions": {
                "importance": "low"
             },
             "actions": {
                "copyToFolder": "AAMkADczNDE4YWEwLTdlZmItNDIzZC04MDViLTYyYjI2YmRh....",
                "stopProcessingRules": true
             }    
}
