如何在具有相同参数的两种不同操作方法之间进行路由

Question

我正在使用属性路由开发ASP.NET Web API 2.我有一个控制器类和两个动作方法:

[RoutePrefix("api/settings")]
    public class SettingsController : ApiController
    {
        [Route("{getVersion}")]
        public async Task<IHttpActionResult> GetDBVersion(string PlatformID)
        {
            try
            {
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                SqlManager sqlManager = new SqlManager();
                DataTable dt = sqlManager.GetLocalDBVersion(PlatformID);

                List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
                Dictionary<string, object> row;
                foreach (DataRow dr in dt.Rows)
                {
                    row = new Dictionary<string, object>();
                    foreach (DataColumn col in dt.Columns)
                    {
                        row.Add(col.ColumnName, dr[col]);
                    }
                    rows.Add(row);
                }
                return Ok(serializer.Serialize(rows));
            }
            catch (Exception ex)
            {
                return Content(HttpStatusCode.ExpectationFailed, ex.Message);
            }
        }
        [Route("getBookingSetting/{PlatformID:int}")]
        public async Task<IHttpActionResult> GetDBBookingSetting(int PlatformID)
        {
            try
            {
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                SqlManager sqlManager = new SqlManager();
                DataTable dt = sqlManager.GetBookingSetting(PlatformID.ToString());

                List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
                Dictionary<string, object> row;
                foreach (DataRow dr in dt.Rows)
                {
                    row = new Dictionary<string, object>();
                    foreach (DataColumn col in dt.Columns)
                    {
                        row.Add(col.ColumnName, dr[col]);
                    }
                    rows.Add(row);
                }
                return Ok(serializer.Serialize(rows));
            }
            catch (Exception ex)
            {
                return Content(HttpStatusCode.ExpectationFailed, ex.Message);
            }
        }

我正在通过url调用第一个操作方法:

/api/settings/getVersion?PlatformID=1

第二个是:

/api/settings/getBookingSetting?PlatformID=1

但是在这两种情况下,每次都会调用第一个操作方法.如何在方法名称不同但参数具有相同名称和类型(或不同类型)的情况下进行路由？

Answer 1

您的路线定义与您的网址不符:

[Route("{getVersion}")]

这需要一个路由参数"getVersion",所以即使是/api/settings/1匹配的URL也是如此.你应该重写它,使它不是一个参数:

[Route("getVersion")]
public async Task<IHttpActionResult> GetDBVersion([FromUri]string PlatformID)

下一个:

[Route("getBookingSetting/{PlatformID:int}")]

此定义需要PlatformID作为路径(ie /api/settings/getBookingSetting/1)的一部分,但您将其作为查询字符串传递.

您应该将定义更改为:

[Route("getBookingSetting")]
public async Task<IHttpActionResult> GetDBBookingSetting([FromUri]int PlatformID)
