No values in POST method's parameters

Question

I have REST web services POST method:

public string Post([FromBody]string value1 )  
{
    return "a";
}

I have placed breakpoint inside of it. I have sent POST:

localhost/RESTServer/api/Person/?value1=1

I get null in value1 inside of Post method. What I do wrong?

You should prob read [When should I use GET or POST method? What's the difference between them?](http://stackoverflow.com/questions/504947/when-should-i-use-get-or-post-method-whats-the-difference-between-them) — Liam, Mar 31 '17 at 12:35

public string Post([FromBody]string value1 )

should be

public string Post([QueryString]string value1 )

(that is ... because your request is a GET and has no body... pure guess)

Well, the request *could* be a `POST`, the question didn't specify. But regardless of the request type, the value is still in the query string. – David Mar 31 '17 at 12:35
sure... but when i read the question, something tells me that it is very likely a GET ;) ... but you are right... it might be a POST – DarkSquirrel42 Mar 31 '17 at 12:37
I'm trying to use POST. But 'FromBody' was generated by Visual Studio 2015 and if I place 'QueryString' I get error 'The type or namespace name 'QueryStringAttribute' could not be found' – vico Mar 31 '17 at 15:46
a new using directive might help you... `using System.Web.ModelBinding;` – DarkSquirrel42 Mar 31 '17 at 15:51
This helped with QueryString. But now I have '405 Method Not Allowed' in client side. – vico Mar 31 '17 at 16:20
different problem -> different question – DarkSquirrel42 Apr 03 '17 at 09:08

Your post request should look something like this, if you intend to use Post
