aspnetcore mvc處理表單提交put

aspnetcore mvc默承認以處理ajax的put,delete之類的操做，但是表單form提交就找不到路由了。

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
            ...

     app.UseHttpMethodOverride(new HttpMethodOverrideOptions {
          FormFieldName = "_method"
     });

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

添加上HttpMethodOverride中間件就能夠把經過在表單加入下面的方式模擬put,delete類提交操做.

<input type="hidden" name="_method" value="put" />
