[英]How to route between two different action methods with same parameters
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操作方法:
[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,在两种情况下,第一个操作方法都会被调用。 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,如何进行路由?
您的路线定义与您的网址不匹配:
[Route("{getVersion}")]
这需要一个路由参数“ getVersion”,因此即使是/api/settings/1
类的URL也将匹配。 您应该重写它,使其不是参数:
[Route("getVersion")]
public async Task<IHttpActionResult> GetDBVersion([FromUri]string PlatformID)
下一个:
[Route("getBookingSetting/{PlatformID:int}")]
此定义期望PlatformID
作为路由的一部分(即/api/settings/getBookingSetting/1
),但是您将其作为查询字符串传递。
您应该将定义更改为此:
[Route("getBookingSetting")]
public async Task<IHttpActionResult> GetDBBookingSetting([FromUri]int PlatformID)
