Accessing route and POST params in Web Api 2 Controller Method

问题

I have a controller that needs access both route and POST body parameters. However when I use this implementation

public class MessageController : ApiController
{
    [Route( "Data/Message/{apiKey}/{userId}" )] 
    [HttpPost]
    public Message Post( Guid apiKey, string userId, [FromBody] string message)
    {
        // ...
    }
}

the message argument is always null.

How can I access all the apropos data?

回答1:

[FromBody] parameters must be encoded as value

don't you try to do this:

public Message Post( Guid apiKey, string userId, [FromBody] string message)
{
    // ...
}

try this instead

 public Message Post( Guid apiKey, string userId, [FromBody] string value)
 {
    // ...
 }

and use this kind of code to do POST request with jquery:

  $.post('YourDomain/Data/Message/{apiKey}/{userId}', { '': value });
