Can a web api post method contains more than one parameter? - post

Question

I have this method in a controller in a web api
public class UserController : ApiController
{
[HttpPost]
public HttpResponseMessage Login(string name, string password){
//dothings
}
}
but if I try a ajax request:
$.ajax({
type: "POST",
url: "http://localhost:19860/Api/User/Login",
data: { name: "name", password: "12345" },
success: succ,
error: err
});
It gives me the error:
Message: "No HTTP resource was found that matches the request URI 'http://localhost:19860/Api/User/Login'."
MessageDetail: "No action was found on the controller 'User' that matches the request."
but, if i remove the parameters it works!
public class UserController : ApiController
{
[HttpPost]
public HttpResponseMessage Login(){
string name= HttpContext.Current.Request.Params["name"];
string password= HttpContext.Current.Request.Params["password"];
// name and password have the value that i passed in the ajax call!!
}
}
why it is like this?
For reasons unrelated to this question, I can't change the web api, so I have to mantain the:
public HttpResponseMessage Login(string name, string password)
format.
Can I mantain this format and be able to make the ajax call?

Answer 1

You can not post multiple parameter to Web-API methods as mentioned in this blog post
There is few alternative to this as follow.
1. Try to pass it on queryString.
Change your ajax function call like below.
$.ajax({
type: "POST",
url: "http://localhost:19860/Api/User/Login?name=name&pass=pass",
data: { name: "name", password: "12345" },
success: succ,
error: err
});
you will get name = name and password = pass in your api controller.
2. Create your own binder as implemented in this blog post.
3. Wrap all the Web-API method parameter in one object or type (recommended).
From the above you can use 1st and 2nd approach as you mentioned in your question you can not change your api method signature.
