Question

配置与错误无关

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

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类：

GlobalConfiguration.Configure(WebApiConfig.Register);

这是错误

但是每当应用程序启动时，我都会遇到此异常：

路径模板分隔符'/'不能连续出现。它必须用参数或文字值

错误是由Route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操作的路由属性中使用了额外的“/”。上述控制器中定义的操作应如下所示：

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

Answer 2

我用两个（或更多）斜杠得到了同样的错误。

[Route("marketdata//tickerinfo")]

更改字符串时很容易发生。

Answer 3

我收到了同样的错误，但它是由我案例中的ActionName属性引起的。

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

虽然这打破了帮助页面，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

我在一个动作上结合了[RoutePrefix]和[Route]来收到此问题。

./score.py 
./myscripts/train.py 
./myscripts/common.py

关于我执行的操作

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

当我更改时：[HttpPost, Route("{someVariable:int}"]到[RoutePrefix("/api/my/application")]，一切都很好。
