我怎么路线在ASP.NET MVC查询字符串的URL？ [英] How do I route a URL with a querystring in ASP.NET MVC?

问题描述

我想在设置一个MVC自定义路由采取URL从另一个系统中的格式如下：

../ ABC / ABC01键= 123安培;组= 456

第二ABC后的01步数这将改变和密钥和参数的集团将改变。我需要的路线这一个动作与步骤号键和组作为paramters控制器。我已经尝试以下code然而，它抛出一个异常：

code：

  routes.MapRoute（
    OpenCase
    ABC / ABC {} stepNo键为{}键放＆;组= {}组，
    新{控制器=ABC1，行动=OpenCase}
）;
 

例外：

 `路由URL不能以'/'或'〜'字符开始，它不能包含？ character.`
 

解决方案

您不能包含在路线查询字符串。

：像这样的路线尝试

  routes.MapRoute（OpenCase，美国广播公司/ ABC {} stepNo
   新{控制器=ABC1，行动=OpenCase}）;
 

然后，控制器上添加一个方法是这样的：

 公共类ABC1：控制器
{
    公众的ActionResult OpenCase（字符串stepno，字符串键，弦乐群）
    {
        //在这里做的东西
        返回查看（）;
    }
}
 

ASP.NET MVC将自动在控制器中的方法的查询字符串参数的参数映射。

I'm trying to setup a custom route in MVC to take a URL from another system in the following format:

../ABC/ABC01?Key=123&Group=456

The 01 after the second ABC is a step number this will change and the Key and Group parameters will change. I need to route this to one action in a controller with the step number key and group as paramters. I've attempted the following code however it throws an exception:

Code:

routes.MapRoute(
    "OpenCase", 
    "ABC/ABC{stepNo}?Key={key}&Group={group}",
    new {controller = "ABC1", action = "OpenCase"}
);

Exception:

`The route URL cannot start with a '/' or '~' character and it cannot contain a '?' character.`

解决方案

You cannot include the query string in the route. Try with a route like this:

routes.MapRoute("OpenCase", "ABC/ABC{stepNo}",
   new { controller = "ABC1", action = "OpenCase" });

Then, on your controller add a method like this:

public class ABC1 : Controller
{
    public ActionResult OpenCase(string stepno, string key, string group)
    {
        // do stuff here
        return View();
    }        
}

ASP.NET MVC will automatically map the query string parameters to the parameters in the method in the controller.
