问题
I happened to find out that for Tweet post ID (e.g. 804443247653322753), when I try to open the page for this Tweet (through URL like https://twitter.com/PolitiFact/status/804443247653322753), it is automatically redirected to Tweet with different Tweet post ID. (e.g. above link will redirect you to https://twitter.com/PolitiFact/status/804418546168041472). It seems quite many Tweet post IDs can redirect to same single Tweet post. Does anyone know why this happens, or what's wrong with those redirected Tweet post IDs?
回答1:
As you know, each tweet has an ID.
A RT is a tweet. So a RT has an ID.
The tweet ID 804443247653322753 has been posted by @hrblock_21 and it is a RT of the tweet ID 804418546168041472 posted by @PolitiFact.
So, this is done by twitter, the web site redirects automatically to the original tweet because it is the only tweet to see (except if the user added a comment when retweeting).
And you can even try https://twitter.com/anyUserName/status/804443247653322753, or https://twitter.com/anyUserName/status/804418546168041472, the tweet to see is the original so it redirects.
