Microsoft Teams Graph API：向团队添加频道失败并出现 404

Question

我尝试使用 Microsoft Graph API 并使用 Invoke-RestMethod 将频道添加到新创建的 Microsoft Teams，并在 Azure Functions 中运行以下 Powershell

我尝试了 v1.0 和 beta 版本，并在高低搜索了这方面的示例：

# code that successfully creates a team based on existing Office 365 Group not shown, but is
# comes from [https://github.com/martinagrom/Ignite2018GroupsGovernanceToolkit][1], f1-CreateGroup and f2-CreateTeam

function AddContent ($folderName) {
Write-Output "Inside of AddContent"
$Body = @{
    "displayName"= "$folderName"
    "description"= "Add decription"
}
$bodyJSON = $body | ConvertTo-Json
Write-Output "Adding channel $($folderName)"
Write-Output "bodyJSON $($bodyJSON)"
try {
    Write-Output "creating channel on https://graph.microsoft.com/beta/teams/$($TeamID)/channels"
    $result = Invoke-RestMethod `
                            -Method POST `
                            -Uri "https://graph.microsoft.com/beta/teams/$($TeamID)/channels" `
                            -ContentType 'application/json' `
                            -Headers $script:APIHeader `
                            -Body $bodyJSON `
                            -ErrorAction Stop

    $TeamResult = $result.id
    Write-Output "Channel created: ID:[$TeamResult]"
} catch [System.Net.WebException] {
    Write-Output "AddChannelOnExistingTeam: $($TeamResult.error.code) => $($TeamResult.error.message)"
    Write-Output "https://graph.microsoft.com/beta/teams/$($TeamID)/channels   ---    $script:APIHeader --- $body"
    If ($_.Exception.Response.StatusCode.value__) {
        $crap = ($_.Exception.Response.StatusCode.value__ ).ToString().Trim();
        Write-Output $crap;
    }
    If  ($_.Exception.Message) {
        $crapMessage = ($_.Exception.Message).ToString().Trim();
        Write-Output $crapMessage;
    }
    $result = $_.Exception.Response.GetResponseStream()
    $reader = New-Object System.IO.StreamReader($result)
    $reader.BaseStream.Position = 0
    $reader.DiscardBufferedData()
    $responseBody = $reader.ReadToEnd();
    Write-Output $responseBody
throw "AddChannelOnExistingTeam: $($TeamResult.error.code) => $($TeamResult.error.message)"
}
catch {
    Write-Output "AddChannelOnExistingTeam: Another Exception caught: [$($_.Exception)]"
    throw "AddChannelOnExistingTeam: $($TeamResult.error.code) => $($TeamResult.error.message)"
}
}

# The team has just been created based on an Office365 group by code (not shown) and the Group/Team ID is in the $TeamResult
# I do a sleep to ensure Team is ready, probably not necessary. Plenty of Write-Out to debug progress. Log futher down
# I grap a list of folder names from a document library and is calling the above function with each name to create a corrosponding channel

Start-Sleep -Seconds 60
$TeamID = $TeamResult
$TeamChannels = $TeamInfo.TeamChannels
Write-Output "TeamChannels $($TeamChannels) on TeamID $($TeamID)"
$sourcesite = $TeamChannels.SubString(0,$TeamChannels.lastIndexOf('/'))
$secpasswd = ConvertTo-SecureString $env:SPO_P -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($env:SPO_U, $secpasswd)
connect-PnPOnline -Credentials $mycreds -url $sourcesite 
$folders = Get-pnpFolderItem -FolderSiteRelativeUrl $TeamChannels.SubString($TeamChannels.lastIndexOf('/')+1)

ForEach ($folder in $folders) {
if ($folder.Name -ne "Forms") {
    AddContent($folder.Name)
}
}

所以 POST to https://graph.microsoft.com/beta/teams/TeamID/channels 恢复为 https://api.teams.skype.com/beta/teams('TeamID')/channels 并以 404 失败

如果我转到 Microsoft Graph Explorer 并输入与创建通道完全相同的信息。

我错过了什么？是否缺少 API 权限？任何提示将不胜感激。

Answer 1

好的，我发现了错误，纯粹的复制粘贴盲... :(

我复制的 Invoke-RestMethod 是一个 PUT 方法，当您尝试使用它创建通道时会出现 404 错误。

因此，当我将其更改为 POST 方法时，它开始工作。我编辑了源代码。
