Azure Functions - ScheduledTaskFunctionExecutionContext

Hi, so I'm converting things across from cloudscript to azure functions and I've a question about the context model.

For functions called from the client I'm using the method in the github example project to create the function context, and then a server api instance:

// using HttpRequestMessage requestvar context = await FunctionContext<T>.Create(request);

Settings.TrySetSecretKey(context.ApiSettings);

var serverApi = new PlayFabServerInstanceAPI(context.ApiSettings, context.AuthenticationContext);

As far as I can see there's no equivalent Create for the scheduled Task Function Execution Context, so how do I go about creating a server api instance in this case?

// HttpRequest req
ScheduledTaskFunctionExecutionContext<dynamic> context = JsonConvert.DeserializeObject<ScheduledTaskFunctionExecutionContext<dynamic>>(await req.ReadAsStringAsync());

What's the step I'm missing?

Are you confused about how to generate PlayFabServerInstanceAPI from ScheduledTaskFunctionExecutionContext? You can try the following code in C# SDK:

var apiSettings = new PlayFabApiSettings   
{  
	TitleId = context.TitleAuthenticationContext.Id, 
	DeveloperSecretKey =
	Environment.GetEnvironmentVariable("PLAYFAB_DEV_SECRET_KEY",EnvironmentVariableTarget.Process),  

};   

var serverApi = new PlayFabServerInstanceAPI(apiSettings);

As you've set TitleID and dev key in Azure portal, you should be able to get dev key with "GetEnvironmentVariable" method, but you may need to change the key to match your setting.

Thanks, that's exactly what I'm looking for. Could you point me in the direction of the c# sdk, I haven't found much documentation tbh.

Check out C# SDK documentation here: https://docs.microsoft.com/en-us/gaming/playfab/sdks/c-sharp/quickstart. Besides, if you are writing code for Azure Function this turorial will be helpful for you: https://docs.microsoft.com/en-us/gaming/playfab/features/automation/cloudscript-af/cloudscript-af-context

Thanks, but I've already seen those. I was rather hoping there was something I'd missed.

Have you got this working with scheduled tasks? Event with setting up the api settings as you've shown I still get an error about the developer secret key being missing when trying to access title data.

You should assign your own Secret Key to the DeveloperSecretKey property. To obtain it, navigate to [Game Manager] ->[Title Settings]->[Secret Keys].

I have. I have no issues running functions called from the client, but I am running into this issue running a scheduled task.
