從視頻網址獲取藤蔓短網址

Question

是否有任何方法從視頻網址（例如https://v.cdn.vine.co/v/videos/A5C08C32-A4AE-4DA4-A717-AEF60FBCA77F-3077-0000013C2DC639D3_1.0.4.mp4?versionId=g7.trI4Z0KR8P9qGEUvZ1LqP8BseMt25）獲取短網址（例如，https://vine.co/v/bnuOqmVhEWb）？

如果有幫助，我也有葡萄樹的postId。

Answer 1

如果你有postId，有一種方法可以按照他們的方式對它進行散列。

vine_key = 'BuzaW7ZmKAqbhMOei5J1nvr6gXHwdpDjITtFUPxQ20E9VY3Ll' 
example_post_id = 910326069930893312 

change example_post_id to base-49 (its vine_key size) 
# => [11, 20, 1, 14, 10, 7, 44, 12, 42, 4, 11] 
replace each digit of the base-49 number with the corresponding character on the vine_key # 0: B, 1: u, 2:z ... 47: L, 48: l 
# => [b, n, u, O, q, m, V, h, E, W, b] 
BOOM, you've got the hashed id 
# => "bnuOqmVhEWb"
