http merge requests

Hi there!

These days I'm trying to implement most of the features needed for our new game and I want to apologize for having so many questions, hehe.

After some troubleshooting, I managed to send GET, POST and PUT requests successfully to Azure Table Storage. I ran into a problem with MERGE requests, which are quite useful to update single properties from our tables: https://docs.microsoft.com/en-us/rest/api/storageservices/merge-entity

The error I'm getting is "Content-Type header value missing.". I tried setting Content-Type both manually in a header, and automatically using the argument provided by http.request, it's still the same.

My first guess would be that Playfab http API won't set the Content-Type header unless the request is POST or PUT... And we need that for MERGE as well (it's just a guess). Can you help me with this?

Cheers!

[Updated] PlayFab CloudScript hasn't yet supported this REST method "merge". Apologies for the confusion. Currently, PlayFab provides this feature -- CloudScript using Azure Functions. And Azure Functions can be used with Azure table storage as this doc says. Please visit the corresponding documentation for more information.

Hi!

Yes, I used the exact format as the one they describe in their sample request and response. My error is "Content-Type header value missing.", even though I tried multiple methods (of setting it inside the http.request parameter or inside my custom headers).

I know that cloud script is compiled using v8 (I read that on another question related to http.request), but the http.request function is a custom Playfab function, not plain Javascript. And since we have to specify the contentType as a separate argument from the headers, I guess it does something special with it.

We can use a combination of GET and PUT (which work perfectly fine with http.request) in order to obtain the same results as MERGE, but it's not that great since we have to use two requests instead of one, and we also have to exchange more data with the table storage. So we would really appreciate if we can get this to work somehow.

Cheers!

Hi guys, any news on this? I've been using Sarah's links and built my headers exactly like in the samples.

"Headers": { "Accept": "application/json", "x-ms-version": "2018-03-28", "x-ms-date": "Tue, 02 Jun 2020 10:30:01 GMT", "DataServiceVersion": "3.0;NetFx", "MaxDataServiceVersion": "3.0;NetFx", "Authorization": "SharedKeyLite <removed>", "Content-Type": "application/json", "Content-Length": 1 }

Like Teodor said, the Put and Get methods are working, but merge isn't. Maybe this is post-processed by you in someway ?

So, even thoough the Content-Type is clearly in the headers, i still get "Content-Type header value missing."

I'm also getting the same issues. I've tested successfully within postman, but using the exact same request settings fails in CloudScript with the missing Content-Type header. It would appear the http library used within CloudScript simply doesn't support custom http request types like MERGE. A work around is to perform a 'GET' to retrieve the full object first, then update the fields you need and do a 'PUT' but this is not ideal as it increases request count and data transferred.

Besides, if using the Azure table storage service in the PlayFab CloudScript is necessary for you, you can try to add a feature request for it.
