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);
}
}
我通过网址调用第一个操作方法:
/api/settings/getVersion?PlatformID=1
和第二个:
/api/settings/getBookingSetting?PlatformID=1
然而,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?
答案 0 :(得分:5)
您的路线定义与您的网址不符:
[Route("{getVersion}")]
这需要一个路由参数&#34; getVersion&#34;,所以即使像/api/settings/1
这样的网址也会匹配。你应该重写它,使它不是一个参数:
[Route("getVersion")]
public async Task<IHttpActionResult> GetDBVersion([FromUri]string PlatformID)
下一步:
[Route("getBookingSetting/{PlatformID:int}")]
此定义期望PlatformID
作为路线的一部分(即/api/settings/getBookingSetting/1
),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)
