即使路线不同，获取路线匹配错误

Question

即使我为

request has been matched with the multiple endpoints

操作定义了不同的路线，我也会收到类似

httpGet

的错误。

代码如下所示，

[Route("api/[controller]")]
[ApiController]
public class CrmManagementController : ControllerBase
{
    [HttpGet("projects")]
    public async Task<ActionResult> ProjectInfo(
        [FromServices] ICrmProjects crmProjects,
        CancellationToken cancellationToken = default)
    {
        _ = crmProjects ?? throw new ArgumentNullException(nameof(crmProjects));

        var vantagepointProjects = await crmProjects.GetAllVantagepointProjectsByNumberAsync(cancellationToken).ConfigureAwait(false);

        return Ok(vantagepointProjects.Values);
    }

    [HttpGet("pursuits")]
    public async Task<ActionResult> PursuitInfo(
        [FromServices] ICrmProjects crmProjects,
        CancellationToken cancellationToken = default)
    {
        _ = crmProjects ?? throw new ArgumentNullException(nameof(crmProjects));

        var vantagepointPursuits = await crmProjects.GetAllVantagepointPursuitsByNumberAsync(cancellationToken).ConfigureAwait(false);

        return Ok(vantagepointPursuits.Values);
    }
}

请告诉我为什么会收到错误以及任何避免该问题的建议。

更新：错误详细信息

fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HN1DKQDVNS2Q", Request id "0HN1DKQDVNS2Q:00000001": An unhandled exception was thrown by the application.
      Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException: The request matched multiple endpoints. Matches:

以下是program.cs文件中的配置

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "api/{controller}/{action}/{id?}");
    endpoints.MapGet("/", () => "This is the sample project");
});

Answer 1

异常消息提到“/”存在冲突的端点/URL。

删除此行：

endpoints.MapGet("/", () => "This is the sample project");

来自

app.UseEndpoints()

应该可以解决您的问题。
