我已经搜索了Stack多年,阅读了MSDN文档并使用了Bing,但是看不出为什么这不起作用！我在路线下面有相关的代码.名为Browse的路由工作得很好,但Details路由的productCode参数总是等于零.如果我制作任何mods,我会继续获得“找不到资源”404页面.
' Lives in controller called 'Details' ' Usage: site.com/details/abc123 Function Index(productCode As String) As ActionResult ' Lives in controller called 'Browse' ' Usage: site.com/browse/scifi/2 Function Index(genre As String,Optional page As Integer = 1) As ActionResult
路线是：
routes.MapRoute( _
"Browse",_
"{controller}/{genre}/{page}",_
New With {.controller = "Browse",.action = "Index",.id = UrlParameter.Optional,.page = UrlParameter.Optional}
)
routes.MapRoute( _
"Details",_
"details/{productCode}",_
New With {.controller = "Details",.action = "Info",.productCode = UrlParameter.Optional}
)
解决方法
订单在定义路线时很重要.
当您请求site.com/details/abc123时,我认为它与您的第一条路线相符.
你会得到
controller =“details”
action =“索引”
genre =“abc123”
这就是您的productCode为空的原因.
切换两个route.MapRoute语句,它应该解决你的问题.
你的第二条路线确实将动作设置为信息而不是索引,但我假设这是一个错字？
