c# - 如何为具有不同参数的同一Controller方法设置不同的路由？

Question

我的 ReportController 看起来像这样:

public IActionResult ReportDetails(int? reportId){
    ....
}

和

public IActionResult ReportDetails(int? reportId, bool ? approved) {
    ....
}

我尝试做一些路由，但失败了。在 Startup.cs 中编写的实际代码:

app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "ReportDetailsValidation",
                    template: "descriptionValidation",
                    defaults: new { controller = "Report", action = "ReportDetails", reportId ="{reportId}", approved = "{approved}" }
                    );

                routes.MapRoute(
                    name: "ReportDetails",
                    template: "description",
                    defaults: new { controller = "Report", action = "ReportDetails"} 
                    );

                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });

如我所见，我需要匹配以下 URL:
/Report/ReportDetails?reportId=7 对于第一个和
/Report/ReportDetails?reportId=7&approved=True 第二个

你可以使用 RouteAttribute

[Route("ReportDetails/{reportId}")]
public IActionResult ReportDetails(int? reportId){
....
[Route("ReportDetails/{reportId}/{approved}")]
public IActionResult ReportDetails(int? reportId, bool ? approved) {
....

您的网址将是；

/Report/ReportDetails/7 为第一个和

/Report/ReportDetails/7/第二个为真

这将适用于默认的 startup.cs

app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });
