我是 Web API 和 .net core 的新手,我有一个开发 API 的任务。
所以我创建了一个默认的 Web API(框架:.NET Core 2.1)并尝试添加路由映射,但我收到了一个错误。
伙计们谁能帮我做路由。
注意:不能使用基于属性的路由,需要像 MVC 一样基于约定处理路由
我的启动程序:
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
//app.UseHttpsRedirection();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "Values", action = "dummyaction" });
});
}
}
这是我得到的错误:
InvalidOperationException: Action 'myproject.Controllers.ValuesController.dummyaction (myproject)' does not have an attribute route. Action methods on controllers annotated with ApiControllerAttribute must be attribute routed.
最佳答案
我是如何让它工作的
即使在使用 map route 之后,我仍然收到关于基于属性的路由的错误
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "Values", action = "dummyaction" });
});
So in the error can you see this line "Action methods on controllers annotated with ApiControllerAttribute must be attribute routed."
现在在我的 Controller 中,我正在使用这个特定的注释/属性“[ApiController]”,通过删除它我能够执行基于约定的路由。
此外,我已将路线更新如下
app.UseMvc(routes =>
{
routes.MapRoute(
name: "api",
template: "api/{controller=Values}/{action=gogogo}/{id?}");
});

关于c# - .NET Core 2.1 Web API 是否支持基于约定的路由?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/57730797/
