PATCH or PUT route and $Webevent.Data is null

[ChrisLynchHPE]

Question

I'm building an API service for my lab, and I'd like to implement either a PATCH or PUT call to modify an internal object for tracking purposes. Essentially the object is one large Hashtable. In my API Patch or Put call, I want to insert a new entry to this Hashtable, which I'll use the .Add(key, value) method. Well, when testing this in operation, the $Webevent.Data property is empty. Here is an example:

    Add-PodeRoute -Method Put, Patch, Post -Path '/api/endpoint' -ScriptBlock {

        Write-PodeJsonResponse -Value @{
            Name = $WebEvent.Data.name
            Value = $WebEvent.Data.value
        }
    }

To invoke this, I'm using the following Invoke-RestMethod call:

# PATCH call
Invoke-RestMethod -uri http://localhost:8080/api/endpoint -Method Patch -Body @{name = "name1"; value = "value1"}

# Returns:

Name Value
---- -----

# PUT call
Invoke-RestMethod -uri http://localhost:8080/api/endpoint -Method Put -Body @{name = "name1"; value = "value1"}

# Returns:

Name Value
---- -----

# POST call
Invoke-RestMethod -uri http://localhost:8080/api/endpoint -Method Post -Body @{name = "name1"; value = "value1"}

# Returns:

Name  Value
----  -----
name1 value1

When I examine $Webevent when either PATCH or PUT is called, Data is empty:

Name                           Value

Is this a bug? Am I using this HTTP method correctly?

Okay, after a bit more testing, it appears that my Invoke-RestMethod was not right. Invoke-RestMethod isn't converting the body from Hashtable to JSON, and I need to then also pass -ContenType "application/json". So, this call achieves what I need:

Invoke-RestMethod -uri http://localhost:8080/api/endpoint -Method Patch -Body (@{name = "name1"; value = "value1"} | ConvertTo-Json) -ContentType "application/json"

# Returns:

Name  Value
----  -----
name1 value1

I'll implement $Webevent.ContentType validation in the route I'm adding to ensure the caller includes that correctly. This API endpoint will only process and handle JSON content, nothing else.
