带有Web API和MVC控制器的ASP.NET的结构

Question

I have a question about the structure of asp.net website, especially back-end stuff

Currently, I have sql database, web api controller and mvc controller. I have been using web api for getting or posting data to database, and using mvc controller for directing webpage.

What I want to do is as followings

It is basically registration process

1. call web api method to post user email and password from mvc controller
2. web api controller processes the user email and password, using stored procedures and functions
3. if the user email already exists in the database, web api returns some custom status code? to let the mvc controller know that.

Here is problem, since the web api will be used by other devices as well so I can't directly do some business logic for dealing with the duplication of email. So I just want to let somehow the MVC controller know the error and do some business logic.

How can I do that?, Is it fine to return some status code like 101, 201 to MVC controller? then How can I do that??

Thanks guys

Use standard HttpResponse with a code from public enum HttpStatusCode Under the link you'll find the list of all codes and some examples how to use and consume them;

for example, in your API controller may return:

return new HttpResponseMessage(HttpStatusCode.NotAcceptable);

and then on the consumer side you'll have to handle that error.
