Posting data to asp.net Web API

问题:

I'm trying to figure out the new ASP.NET Web API.

So far I've been able to create this method signature and connect to it just fine and get a valid response...

[HttpPost]
public HttpResponseMessage CreateAccount()

I am able to send a request to this method with fiddler and have verified that it is receiving the request.

However, when I try to pass data is when I am running into a problem.

The first thing I tried was...

[HttpPost]
public HttpResponseMessage CreateAccount([FromBody]string email, [FromBody]string password)

And I type

email:xyz,password:abc

into the body of the request in fiddler. When I do this I get a 500 error stating

'Can't bind multiple parameters ('email' and 'password') to the request's content.'

I have also tried this as a method signature...

[HttpPost]
public HttpResponseMessage CreateAccount([FromBody]UserAccountRequestData data)

with the UserAccountRequestData being a simple POCO

public class UserAccountRequestData
{
    public string Email { get; set; }
    public string Password { get; set; }
}

And I put

{Email:xyz,Password:abc}

or

data:{Email:xyz,Password:abc}

into the body of the request. In both cases trying to populate the POCO I am able to reach the method while debugging, but the data object is always null.

I need to understand how to create API methods that accept both strongly typed POCOs and others that accept multiple primitive types like strings and ints.

Thanks

You need to set the Content-Type header to application/json and then provide valid JSON.

{"Email":"xyz","Password":"abc"}
