Facebook点赞按钮+点赞的页面请求登录 [英] Facebook Like button +The page being liked request login

问题描述

嗨！

使用Facebook的赞"按钮对我来说是个大问题.我有一个产品页面，其中有一个喜欢按钮，要访问该页面，您需要登录.

我用这种方法填充元数据:

Hi!

I have a big problem for me with the like button for Facebook. I have a products page where i have a like button and to reach this page you need to be logged in.

I fill the meta data with this method:

private void LoadMetaTagsForFacebook()
{
    HtmlMeta meta = new HtmlMeta();
    meta.Attributes.Add("property", "fb:app_id");
    meta.Attributes.Add("content", "");
    Page.Header.Controls.Add(meta);

    meta = new HtmlMeta();
    meta.Attributes.Add("property", "og:url");
    meta.Attributes.Add("content", Request.Url.ToString());
    Page.Header.Controls.Add(meta);

    meta = new HtmlMeta();
    meta.Attributes.Add("property", "og:site_name");
    meta.Attributes.Add("content", "Site.com");
    Page.Header.Controls.Add(meta);

    meta = new HtmlMeta();
    meta.Attributes.Add("property", "og:title");
    meta.Attributes.Add("content", this._product.Name);
    Page.Header.Controls.Add(meta);

    meta = new HtmlMeta();
    meta.Attributes.Add("property", "og:image");
    meta.Attributes.Add("content", this._product.ImagePath);
    Page.Header.Controls.Add(meta);

    meta = new HtmlMeta();
    meta.Attributes.Add("property", "og:type");
    meta.Attributes.Add("content", "drink");
    Page.Header.Controls.Add(meta);
}

当我运行Facebook调试器时，出现此错误:

推断属性:即使可以从其他标签推断值，也应明确提供og:url属性.
推断属性:即使可以从其他标签推断值，也应明确提供og:title属性.
推断的属性:即使可以从其他标签推断一个值，也应明确提供og:description属性.
推断的属性:即使可以从其他标签推断值，也应明确提供og:image属性.

1.当我在网站上查看页面源代码时，meta标签是正确的..我是否必须以其他方式添加meta标签?我该怎么办?

2.我也收到错误消息(302)，因为我有一个重定向路径(您必须先登录才能看到该页面).解决方案是什么?

我会很高兴获得answear，我花了4个小时进行搜索和尝试.

When i run the facebook debugger i get this error:

Inferred Property: The ''og:url'' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property: The ''og:title'' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property: The ''og:description'' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property: The ''og:image'' property should be explicitly provided, even if a value can be inferred from other tags.

1. When i look at the page source on the site the meta tags is right.. do i have to add the meta tags in a other way? How do i do that?

2. I also get a error (302) because i have a redirect path (you have to be logged in to see the page). What´s the solution for this?

I would be very happy for an answear, i have spent 4 hours searching and trying.

Thanks alot!
