Attribute routing with multiple parameters

Question

Here is the method in my controller which is called:

app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });

Answer 1

Your route: [HttpGet("price/{priceone?}/{pricetwo?}")] doesn't match your request /price/30.0&35.0 . This is why you are getting a bad request.

Correct request path would be /price/30.0/35.0

You can alternaliverly pass in these values as a query string eg: /price/?priceone=30.5&pricetwo=35.0

and then add [FromQuery] in your Get method like this: public IActionResult ByPrice([FromQuery] double? priceone, [FromQuery] double? pricetwo)
