Question

我定义了以下路线：

GlobalConfiguration.Configuration.Routes.Add(
    "iOS Service",
    new HttpRoute("ios/{controller}/{action}/{id}", new HttpRouteValueDictionary { { "id", RouteParameter.Optional } })
);

GlobalConfiguration.Configuration.Routes.MapHttpRoute(
    name: "iOS Service Documents",
    routeTemplate: "ios/getfulldocumentstructure",
    defaults: new { controller = "Documents", action = "GetFullDocumentStructure" }
);

GlobalConfiguration.Configuration.Routes.MapHttpRoute(
    name: "iOS Service AppInfo",
    routeTemplate: "ios/appinfo",
    defaults: new { controller = "AppInfo", action = "GetAppInfo" }
);

GlobalConfiguration.Configuration.Routes.MapHttpRoute(
    name: "iOS Service Html",
    routeTemplate: "ios/html/{language}/{contentId}",
    defaults: new { controller = "Html", action = "GetHtml", language = RouteParameter.Optional, contentId = RouteParameter.Optional }
);

使用以下控制器：

public class HtmlController : ApiController
{
    [HttpGet]
    public string GetHtml(long language, long contentId)
    {

        return "Hello";
    }
}

如果我使用http://localhost/ios/html?languageId=1033&contentId=12345点击服务，则会触发GetHtml操作。

如果我使用http://localhost/ios/html/1033/12345点击服务，则会收到错误消息，指出控制器中没有找到匹配的操作。

我做错了什么？

Answer 1

如果您的参数是可选的，那么可以试试这个：

public class HtmlController : ApiController
{
    [HttpGet]
    public string GetHtml(long? languageId, long? contentId)
    {

        return "Hello";
    }
}

将捕获所有路径移动到最后修复了问题。电话打到了错误的控制器：

GlobalConfiguration.Configuration.Routes.MapHttpRoute(
    name: "iOS Service Documents",
    routeTemplate: "ios/getfulldocumentstructure",
    defaults: new { controller = "Documents", action = "GetFullDocumentStructure" }
);

GlobalConfiguration.Configuration.Routes.MapHttpRoute(
    name: "iOS Service AppInfo",
    routeTemplate: "ios/appinfo",
    defaults: new { controller = "AppInfo", action = "GetAppInfo" }
);

GlobalConfiguration.Configuration.Routes.MapHttpRoute(
    name: "iOS Service Html",
    routeTemplate: "ios/html/{language}/{contentId}",
    defaults: new { controller = "Html", action = "GetHtml", language = RouteParameter.Optional, contentId = RouteParameter.Optional }
);

GlobalConfiguration.Configuration.Routes.Add(
    "iOS Service",
    new HttpRoute("ios/{controller}/{action}/{id}", new HttpRouteValueDictionary { { "id", RouteParameter.Optional } })
);
