也许您可以为所有控制器使用从Controller派生的基类，并添加和重写OnActionExecuting。

像这样使用DelegatingHandler：

public class MyCustomHeaderHandler : DelegatingHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        // Check if the request contains the required header
        if (!request.Headers.Contains("requiredHeader"))
        {
            return request.CreateResponse(HttpStatusCode.PreconditionFailed);
        }

        // else, pass the request to the next handler in the pipeline
        return await base.SendAsync(request, cancellationToken);
    }
}

并将其优先于其他注册到管道中：

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {

        config.MessageHandlers.Add(new MyCustomHeaderHandler());

        // Other configurations ....
    }
}
