php - Will dynamically inserted meta tags(by javascript) be detected and picked up by Twitterbot? (twitter photo card) -

-

Is this possible? Does TweeterBot detect and process dynamically inserted meta tags? If not, it would mean that the meta tag should be presented with a server-side script. However, the one on which I am working uses the hashtag to dynamically change the content (AJAX). What will be the best and proven approach in this environment?

Thank you for your help.

As far as I have tried, the Twitterbot crawler does not present JavaScript. In my case, I am generating a meta tag for the Twitter card only when * HTTP_USER_AGENT * is the TwitterBot code starts with something like this. 

  If you want to check (Strippo ($ _ server ['HTTP_USER_AGENT'], 'twitterbot') == incorrect) {  
 Whether or not your code works by testing the URL of the Twitter card on its valeteur.  
 Hope this help!

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
