路由模板分隔符'/'不能连续出现-属性路由问题

Question

配置与错误无关

这是我在 App_Start/WebApiConfig.cs:

中的 Web API 配置

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 class:

GlobalConfiguration.Configure(WebApiConfig.Register);

这是错误

但是每当应用程序启动时，我都会收到此异常：

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

错误是由路由属性引起的

这就是我在控制器上使用属性路由的方式：

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

Answer 1

出现上述错误的原因是我在动作的路由属性中使用了额外的'/'。上面controller中定义的action应该是这样的：

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

Answer 2

我有两个（或更多）斜线的相同错误。

[Route("marketdata//tickerinfo")]

换字符串的时候很容易出现

Answer 3

我遇到了同样的错误，但在我的案例中这是由 ActionName 属性引起的。

[ActionName("")]
public void Get(string code)

虽然这破坏了帮助页面，但我仍然能够到达端点 api/controller?code=123。当我删除 ActionName 属性时，错误消失了。

Answer 4

我收到的这个问题是关于一个动作的 [RoutePrefix] 和 [Route] 的组合。

[RoutePrefix("/api/my/application")]

在行动我有

[HttpPost, Route("{someVariable:int}"]

当我改变：[RoutePrefix("/api/my/application")]到[RoutePrefix("api/my/application")]一切都很好。
