具有动态内容的角度通用更新元标签 [英] angular universal update meta tags with dynamic content

问题描述

嘿，我遇到了一个博客页面，其中包含动态数据，我想用这些数据来填充元标记，例如，我正在做类似的事情

Hey I'm having an issue I have this blogs page that brings in dynamic data, and with that data I want to use it to populate meta tags so for example I'm doing something like this

getBlogPost() {
  this.http.get(...)
     .subscribe(result => {
         this.blogPost = result;
         this.meta.updateTag({ name: 'description', content: this.blogPost.fields.metaDescription });
         this.meta.updateTag({name: 'robots', content: 'INDEX, FOLLOW'});
         this.title.setTitle(this.blogPost.fields.blogName);
         this.meta.updateTag({name: 'twitter:image:src', content: this.blogPost.includes.Asset[0].fields.file.url });
         this.meta.updateTag({name: 'twitter:title', content: this.blogPost.fields.blogName });
         this.meta.updateTag({name: 'twitter:description', content: this.blogPost.fields.metaDescription });
         this.meta.updateTag({property: 'og:title', content:  this.blogPost.fields.blogName});
         this.meta.updateTag({property: 'og:description',  content: this.blogPost.fields.metaDescription});
         this.meta.updateTag({property: 'og:image', content: this.blogPost.includes.Asset[0].fields.file.url });
         this.meta.updateTag({property: 'og:image:secure_url', content: this.blogPost.includes.Asset[0].fields.file.url});
     })
}

现在所有迹象都表明这应该可行，但是在查看源代码时我看不到更新的meta标签，而在检查SEO工具时也看不到它们.

Now all signs point to this should work but I don't see the updated meta tags when I view the source code and I don't see them when I check SEO tools...

对此有解决方案吗?

先谢谢了！

推荐答案

我有一个在Angular 7中完全实现的博客.这就是我无需使用Angular Universal就能动态使用Facebook元标记的方法:

I have a blog fully implemented in Angular 7. Here's how I was able to use Facebook meta tags dynamically without using Angular Universal:

1)在我的后端(在我的情况下是Spring Boot)中，我根据当前的博客文章创建了一个服务来生成HTML文件.我要根据我的博客文章(例如标题，缩略图等)在HTML的标题中添加所有特定的Facebook标签.

1) in my backend (in my case it's Spring Boot) I created a service to generate an HTML file according to my current blog post. I am adding all the specific Facebook tags in the header of this HTML according to my blog post (like title, thumbnail, etc.)

2)在我的HTML中，添加转到博客文章"链接

2) In my HTML I add a "Go to Blog post" link

3)当我想分享帖子博客时，我是在Facebook上分享生成的HTML URL.因此标题，缩略图等均根据我当前的帖子内容而定.

3) When I want to share the post blog, I am sharing the generated HTML URL on Facebook. And thus the title, thumbnail, etc. are according to my current post content.
