Upload AG plugin through api

[ynias_reynders]

We are currently automating our plugin deployment. But we can't get the POST call right to upload the zip (or plugin.json) file to our managed server.

We tryd it through Invoke-RestMethod with the following config:

$urlPluginAPI = "https://dynatrace.xxxx.be/e/xxx-xxx-xxx-xxx/api/config/v1/plugins?overrideAlerts=false"
$headers = @{
    Authorization='Api-Token notArealToken'
}
$FileContent = [IO.File]::ReadAllBytes($zipPath)
$Fields = @{file=$FileContent};

Invoke-RestMethod -Uri $urlPluginAPI -ContentType 'multipart/form-data' -Method Post -Headers $Headers -Body $Fields;

But we got the following result from that:

Invoke-RestMethod : {"error":{"code":400,"message":"HTTP 400 Bad Request"}}
At line:8 char:1
+ Invoke-RestMethod -Uri $urlPluginAPI -ContentType 'multipart/form-dat ...

   est) [Invoke-RestMethod], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Comma 
   nds.InvokeRestMethodCommand

We also tryd it through Windows Curl with the following results

C:\Users\REM_Dynatrace01\curl-7.66.0-win64-mingw\bin>curl -X POST 'https://dynatrace.xxxx.be/e/xxx-xxx-xxx-xxx/api/config/v1/plugins' -H 'Authorization: Api-token notArealToken' -H 'content-type: multipart/form-data'  -F file=@C:\Users\REM_Dynatrace01\Documents\custom.remote.python.

Anybody that got a working example that we can do through Powershell? Preferably through Invoke-RestMethod

[piotr_kuchta · Accepted solution]

I would say PowerShell is not the best tool to do that, but it is possible.

There are two problems:
1. PowerShell constructs request as specified in body (so no magic that will fill stuff for you)

2. The way you passed fileContent to body, resulted in having "System.Byte%5B%5D" in request instead of bytes itself.

$zipName = "custom.remote.python.demo.zip"
$zipPath = "your\\path\\to\\plugin\\$zipName"
$urlPluginAPI = "https://dynatrace.xxxx.be/e/xxx-xxx-xxx-xxx/api/config/v1/plugins?overrideAlerts=false"
$headers = @{
    'Authorization'='Api-Token some-token'
}
$FileContent = [IO.File]::ReadAllBytes($zipPath)
$ct = [System.Text.Encoding]::GetEncoding("iso-8859-1").GetString($FileContent)

$boundary = [System.Guid]::NewGuid().ToString()

$LF = "`n"
$bodyLines = (
    "--$boundary",
    "Content-Disposition: form-data; name=`"file`"; filename=`"$zipName`"",
    "Content-Type: application/zip$LF",
    $ct,
    "--$boundary--$LF"
    ) -join $LF


Invoke-RestMethod -Uri $urlPluginAPI  -Body $bodyLines -Headers $Headers -Method Post -ContentType "multipart/form-data; boundary=`"$boundary`"" -TimeoutSec 20

that's the code that worked for me
