路由模板分隔符"/"不能连续出现-属性路由问题 [英] The route template separator character '/' cannot appear consecutively - Attribute routing issue

问题描述

这是我在App_Start/WebApiConfig.cs中对Web API的配置:

This is my configuration for the Web API in App_Start/WebApiConfig.cs:

public static void Register(HttpConfiguration config)
    {
        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );.....

这是我的global.asax类:

And this is my global.asax class:

GlobalConfiguration.Configure(WebApiConfig.Register);

这是错误

但是，每当应用程序启动时，都会出现此异常:

This is the error

But whenever the application is starting, I get this exception:

路由模板分隔符"/"不能连续出现.必须用参数或文字值分隔

The route template separator character '/' cannot appear consecutively. It must be separated by either a parameter or a literal value

该错误是由Route属性引起的

这是我在控制器上使用属性路由的方式:

The error is caused by the Route attribute

This is how I am using attribute routing on my controller:

[RoutePrefix("v1")]
public class MarketController : ApiController
{
    [HttpGet]
    [Route("/marketdata/tickerinfo")]
    public IHttpActionResult TickerInfo(string currencyPair)
    {

推荐答案

出现上述错误的原因是，我在该操作的route属性中使用了附加的'/'.上述控制器中定义的操作应如下:

The reason for the above error is that I am using an additional '/' in the route attribute for the action. The action defined in the above controller should be as follows:

    [HttpGet]
    [Route("marketdata/tickerinfo")]
    public IHttpActionResult TickerInfo(string currencyPair)
    {
