如何获取当前的 Azure FunctionNameAttribute？

Question

如何在函数内部以编程方式访问使用 [FunctionName("SomeFunctionName")] 设置的函数名称？

这是函数属性名称而不是方法名称。

例如：在下面的代码中，我想做类似 if (!await PermissionsHelper.userHasPermission(getCurrentFunctionAttributeName(), TokenHelper.getTokenValue(req, "oid")))

的事情

  public static class GetUser
  {
    [FunctionName("GetUser")]
    public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "users/{id}")]
          HttpRequest req,
          String id,
          ILogger log)
    {

      if (!await PermissionsHelper.userHasPermission("GetUser", TokenHelper.getTokenValue(req, "oid")))
        return new UnauthorizedResult();

尝试以下操作：

public static class GetUser
{
  [FunctionName("GetUser")]
  public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "users/{id}")]
      HttpRequest req,
      String id,
      ExecutionContext executionContext,
      ILogger log)
  {

    if (!await PermissionsHelper.userHasPermission(executionContext.FunctionName, TokenHelper.getTokenValue(req, "oid")))
    return new UnauthorizedResult();
