Why get error 404 when I try to pass date variable in get request to web api method?

Question

I work on my web api project. I get error 404 when I try to pass date variable in get request to web api method.

Here is web api method:

[HttpGet]
[Route("ReportDetailed/{clientId}/{date}")]
public IHttpActionResult ReportDetailed(int clientId, DateTime date )
{
    return Ok();
}

And here how I try to access to the function above(row from URL):

http://localhost/station/api/Reports/ReportDetailed/12/Wed%20Jun%2001%202016%2000:00:00%20GMT+0300%20(Jerusalem%20Daylight%20Time)

where clientId is 12 and date is parsed javascript date object:

/Wed%20Jun%2001%202016%2000:00:00%20GMT+0300%20(Jerusalem%20Daylight%20Time)

when I remove from URL above the parsed Date object and date parameter from web api function it works perfect (so I guess the problem with date object).

Any idea why I get error 404 when I try to pass object in URI?

What if you try a more simplified date, eg: /ReportDetailed/12/2016-06-06? Does that work? If so, it's the model binder for date not recognising your date - you could use a string param and parse it in your action (throwing an exception if you can't parse it) — fdomn-m

Your provided date is not in a valid date format. Try a more universally parse-able format like YYYY-MM-dd HH:mm:ss for example.

You should also use Route constraints on your parameters which will try to validate your parameters to make sure they are in the correct format

[HttpGet]
[Route("ReportDetailed/{clientId:int}/{date:datetime}")]
public IHttpActionResult ReportDetailed(int clientId, DateTime date )
{
    return Ok();
}

Date format is not recognizable by .NET First convert your date to UTC string, this will return a string representation of your date. So the value will be passes as string

var dateString= dateJs.toUTCString();

Then in your C# code parse it.

public IHttpActionResult ReportDetailed(int clientId, string dateString)
    DateTime dateC# = DateTime.Parse(dateString);

Katana, when I try to parse toUTCString() I get wrong date: "Tue, 31 May 2016 21:00:00 GMT"

@Michael I think you are creating a new date instance. Use the value you pasted above. Michael is the error in the API gone?

@Michael sorry i forgot to mention that the output of toUTCString is a string so need to change your datetime parameter in API to string

I use toISOString()

I get date undefined in the action
