如题
虽然推特上面有说明
https://help.twitter.com/en/using-twitter/how-to-tweet-a-link
1.Type or paste the URL into the Tweet box on twitter.com.
2.A URL of any length will be altered to 23 characters, even if the link itself
is less than 23 characters long. Your character count will reflect this.
3.Click the Tweet button to post your Tweet and link.
