如何在 MVC C# Razor 中使用 Google Adsense

Question

我正在尝试将 Google Adsense 添加到我的 MVC 移动网络应用程序中。我想实施 Google Adsense 移动内容广告代码。他们拥有的脚本语言是asp 3.0。是否有可用于在 MVC C# Razor 页面上显示这些广告的 MVC 助手？我根本找不到任何关于 MVC 和在线显示网络广告的信息。希望得到一些帮助，我完全被困住了。

如果我使用常规的 Adsense Javascript 代码。当我在站点周围单击时，代码不会加载。只有当我点击页面上的刷新时。

从 Adsense ASP 示例翻译的简单 HtmlHelper：

public static class AdsenseHelper
{
    public static MvcHtmlString Adsense(this HtmlHelper htmlHelper, string clientKey, string adSlot)
    {
        var context = htmlHelper.ViewContext.HttpContext;
        var request = context.Request;

        int googleTime = (DateTime.Now - new DateTime(1970, 1, 1)).Days;
        var googleDt = (1000 * googleTime) + Math.Round(1000d * (DateTime.Now - DateTime.Today).Milliseconds);

        var googleUserAgent = context.Server.UrlEncode(request.ServerVariables["HTTP_USER_AGENT"]);
        var googleScheme = (string.Compare(request.ServerVariables["HTTPS"], "on") == 0) ? "https://" : "http://";

        var googleAdUrl =
            "http://pagead2.googlesyndication.com/pagead/ads?" +
            "client=" + clientKey + // ca-mb-pub-0000000000000000
            "&dt=" + googleDt +
            "&ip=" + context.Server.UrlEncode(request.ServerVariables["REMOTE_ADDR"]) +
            "&markup=xhtml" +
            "&output=xhtml" +
            "&ref=" + context.Server.UrlEncode(request.ServerVariables["HTTP_REFERER"]) +
            "&slotname=" + adSlot + // 0000000000
            "&url=" + context.Server.UrlEncode(googleScheme + request.ServerVariables["HTTP_HOST"] + request.ServerVariables["URL"]) +
            "&useragent=" + googleUserAgent +
            GoogleScreenRes(context.Request) +
            GoogleMuid(context.Request) +
            GoogleViaAndAccept(context, googleUserAgent);

        using (var client = new System.Net.WebClient())
        {
            string result = client.DownloadString(googleAdUrl);
            return new MvcHtmlString(result);
        }
    }

    private static string GoogleColor(string value, int random)
    {
        var colorArray = value.Split(',');
        return colorArray[random % (colorArray.Length)];
    }

    private static string GoogleScreenRes(HttpRequestBase request)
    {
        var screenRes = request.ServerVariables["HTTP_UA_PIXELS"];
        char delimiter = 'x';
        if (string.IsNullOrEmpty(screenRes))
        {
            screenRes = request.ServerVariables["HTTP_X_UP_DEVCAP_SCREENPIXELS"];
            delimiter = ',';
        }
        if (string.IsNullOrEmpty(screenRes))
        {
            screenRes = request.ServerVariables["HTTP_X_JPHONE_DISPLAY"];
            delimiter = '*';
        }

        if (screenRes != null)
        {
            string[] resArray = screenRes.Split(new[] { delimiter }, 2);
            if (resArray.Length == 2)
            {
                return "&u_w=" + resArray[0] + "&u_h=" + resArray[1];
            }
        }
        return string.Empty;
    }

    private static string GoogleMuid(HttpRequestBase request)
    {
        var muid = request.ServerVariables["HTTP_X_DCMGUID"];
        if (!string.IsNullOrEmpty(muid))
        {
            return "&muid=" + muid;
        }
        muid = request.ServerVariables["HTTP_X_UP_SUBNO"];
        if (!string.IsNullOrEmpty(muid))
        {
            return "&muid=" + muid;
        }
        muid = request.ServerVariables["HTTP_X_JPHONE_UID"];
        if (!string.IsNullOrEmpty(muid))
        {
            return "&muid=" + muid;
        }
        muid = request.ServerVariables["HTTP_X_EM_UID"];
        if (!string.IsNullOrEmpty(muid))
        {
            return "&muid=" + muid;
        }
        return string.Empty;
    }

    private static string GoogleViaAndAccept(HttpContextBase context, string googleUserAgent)
    {
        if (string.IsNullOrEmpty(googleUserAgent))
            return string.Empty;

        string googleViaAndAccept = string.Empty;
        var via = context.Server.UrlEncode(context.Request.ServerVariables["HTTP_VIA"]);
        if (!string.IsNullOrEmpty(via))
        {
            googleViaAndAccept = "&via=" + via;
        }
        var accept = context.Server.UrlEncode(context.Request.ServerVariables["HTTP_ACCEPT"]);
        if (!string.IsNullOrEmpty(accept))
        {
            googleViaAndAccept = googleViaAndAccept + "&accept=" + accept;
        }

        return googleViaAndAccept;
    }
}

此帮助程序不适用于桌面浏览器。但可以通过将用户代理更改为 Opera Mini 来绕过。

就像谷歌说的：

AdSense 移动内容广告仅适用于针对旧功能手机设计的网站。随着完全支持网络的智能手机变得越来越普遍，我们建议您使用 AdSense 内容广告来满足您的所有内容广告需求。
