如何在 angularjs SPA 上获得 301 响应 - dotnet

问：

我在网络选项卡上看到 301 响应，但在去向或任何 SEO 重定向工具上，我得到了 200 响应。知道如何欺骗 SEO 工具以获得 301 重定向响应吗？

控制器

[HttpGet]
[Route("Redirector")]
public HttpResponseMessage Redirector(string targetUrl)
{
    var httpResponse = Request.CreateResponse(HttpStatusCode.MovedPermanently);
    httpResponse.Headers.Add("X-Redirect-Status", "301");
    httpResponse.Content = new StringContent(targetUrl);

    return httpResponse;
}

JS系列

this.redirector = function (newUrl) {
    return $http.get("/api/redirect/Redirector?targetUrl=" + newUrl);
};

$ctrl.redirector = function (newUrl) {
    redirectService.redirector(newUrl)
        .then(function (response) {
            var newLocation = response.data;
            $location.path(newLocation);
        })
        .catch(function (error) {
            var newLocation = error.data;
            $location.path(newLocation);
        });
};
