Configure CORS for Azure Functions Local Host

问题

I'm testing an Azure Functions app locally with the Azure Functions CLI tooling. Is there any way I can configure CORS settings for the local host?

回答1:

You can start the host like this

func host start --cors *

You can also be more specific and provide a comma delimited list of allowed urls

More here: https://github.com/Azure/azure-webjobs-sdk-script/issues/1012

You can configure CORS in the local settings file local.settings.json:

{
  "Values": {
  },
  "Host": {
    "CORS": "*"
  }
}

Settings in the local.settings.json file are used only when you're running projects locally

If you're having issues passing in the params via Visual Studio's Debug's "Application Arguments". This is how to pass the params from the command line:

1) Open an ordinary command prompt.

2) cd to your solution's compiled dll, i.e. "Your Solution Path"\bin\Debug\netstandard2.0

3) start the Azure function runtime from the command line, i.e.:

dotnet "C:\Users\USER\AppData\Local\Azure.Functions.V2.Cli\func.dll" host start --port 7071 --cors * --pause-on-error

4) To debug in Visual Studio, Debug->Attach to Process.. and attach to the donet.exe that will be running.

Hope that helps prevent someone from banging their head too much...

Another easy way to configure CORS on Azure Functions is to use Azure Portal,

1- Go to the Function App Settings in Azure Portal

2 - Click on CORS and add your local host url

And there you have it!!

Hope this helps someone.
