在Route属性ASP.NET MVC的URL中添加自定义单词

Question

How to add a custom, user defined word in the URL of some MVC call?

For example I have this attribute on my controller's method:

[Route("accounts/transactions"]

What I'm trying to do is to change that route into this form: /accounts/{accountNumber}/transactions

Where accountNumber is changeable and send by client in the moment when request is send. Client send his account number via URL like this: localhost:50490/accounts/1234567890/transactions and controller method gets invoked.

Can I change Route parameter somehow so it can handle this situation or I need completely different solution.

Answer 1

Yes you can change the route to handle this situation.

Solution 1:

 [Route("accounts/{accountNumber:int}/transactions"]
 public ActionResult Transactions(int accountNumber) {
     /* action body */
 }

Notes:

1) accountNumber:int is just for integer and don't allow null.

2) Your action must have accountNumber as parameter.

Solution 2: You can add this route in RouteConfig

 routes.MapRoute(
      name: "accountNumber",
      url: "accounts/{accountNumber}/transactions",
      defaults: new { controller = "Accounts", action = "Transactions" }
 );

Your Action must take that as a parameter

 public ActionResult Transactions(string accountNumber) {
     /* action body */
 }
