The request matched multiple endpoints when migrated from .NET Core 2.1 to .NET 6-CodePudding

This two action routing works fine in .netcore 2.1 but after migrate to .netcore 6 shown error: AmbiguousMatchException: The request matched multiple endpoints I followed https://learn.microsoft.com/en-us/aspnet/core/fundamentals/routing?view=aspnetcore-6.0 but could not resolved the issue.

//Just for two route /content/game & /content/software  
[Route("/content/{pageId=game}")]
[Route("/content/{pageId=software}")]
public IActionResult Index1(string pageId, [FromQuery] int page=1)
{}

//For all other url(/content/*)
[Route("/content/{package}")]
public IActionResult Index2(string package)
{}

CodePudding user response：

You use regex to achieve it, Please refer:

//only match /context/game or /content/software

[Route("/content/{pageId:regex(^(game|software)$)}")]
[HttpGet]
public int Index1(string pageId, [FromQuery] int page = 1)
{
    return 2;
}

//For all other url(/content/*)      
[Route("/content/{package:regex(^(?!.*(game|software)).*$)}")]
[HttpGet]
public int Index2(string package)
{
   return 1;
}
