og:url incorrect when site is put under subdirectory

[leesei]

_config.yml

# URL
## If your site is put in a subdirectory, set url as 'http://yoursite.com/child' and root as '/child/'
url: http://yoursite.com/child
root: /child/

In HTML's meta

<meta property="og:url" content="http://yoursite.com/child/child/">

Same here.

I am having the same issue. I have fixed it for now by adding a replacement for the 'url' option of open_graph in the layout/_partial/head.ejs:

url: url.replace('/blog/blog', '/blog') - my blog is in the '/blog' subdirectory.

<%- open_graph({twitter_id: theme.twitter, google_plus: theme.google_plus, fb_admins: theme.fb_admins, fb_app_id: theme.fb_app_id, url: url.replace('/blog/blog', '/blog')}) %>

Same problem here. Problem is facebook won't display images when sharing links that have the invalid og:image tags. I worked it around by commenting those out.

But it seems the true fix really should be in node_modules\hexo\lib\plugins\helper\open_graph.js:

  images = images.map(function(path) {
    if (!urlFn.parse(path).host) {
      if (path[0] !== '/') path = '/' + path;
      return config.url + path;  // <------ THIS IS WRONG
    }

    return path;
  });

THe marked line above is wrong. Instead, we should use something like return currentPageUrl + path;. But I don't know how to get currentPageUrl in that file. Any hint?

OK. I've fixed this with:

  images = images.map(function(path) {
    if (!urlFn.parse(path).host) {
      if (path[0] !== '/') {
        return urlFn.resolve(url, path);
      }
    }

    return path;
  });
