如何在 Visual Studio 中的不同端口上运行 Azure Function 应用程序 [英] How to run Azure Function app on a different port in Visual Studio

问题描述

I am setting local host port in local.setting.json. Referring Microsoft doc https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local

The file looks like below

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "AzureWebJobsDashboard": ""   
  },
  "Host": {
    "LocalHttpPort": 7073
  }
}

When I run/debug the solution , VS still host the app on default port (7071)

I have checked the bin directory, the local.setting.json file is geting there with above settings. Running Azure Fucntion CLI (func host start) from bin directory correctly read the port number.

Looks like VS is not using the "LocalHttpPort" port. Is there any other changes required in the settings. I have Visual Studio 2017 Preview (2)

解决方案

Update: If you're just looking to change the port, you don't have to set it through the file specified in the question. Check Thuc Nguyen answer

Original answer:

the command line takes precedence over the settings file, the problem is that VS passes an explicit port on the command line.

work around is to go through project -> properties -> Debug, then under Application arguments take control of the args. you can type host start --pause-on-error

Edit from ravinsp:

Update for .Net Core 2.0 function project:

The command line arguments you have to pass are different. You have to pass in the path to a dll in front. Like this: %AppData%..LocalAzure.Functions.V2.Cli2.0.1-beta.22Azure.Functions.Cli.dll host start --pause-on-error You can see for yourself by running the function in Visual Studio and using the process explorer to see command line args to dotnet.exe process.
