将SHA1转换为base64

Question

努力将sha1转换为base64

import hashlib
import hmac
import base64

base_string = "POST&https%3A%2F%2Fsecure.trademe.co.nz%2FOauth%2FRequestToken&oauth_callback%3Dhttp%253A%252F%252Fwww.website-tm-access.co.nz%252Ftrademe-callback%26oauth_consumer_key%3DC74CD73FDBE37D29BDD21BAB54BC70E422%26oauth_nonce%3D7O3kEe%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1285532322%26oauth_version%3D1.0%26scope%3DMyTradeMeRead%252CMyTradeMeWrite".encode()
KEY = b"3B61C8A3FF9F1F6C0DBE436F9B507E08EF&"
hmac.new(KEY, base_string, hashlib.sha1).base64()

AttributeError：'HMAC'对象没有属性'base64'

我认为您需要在摘要上调用base64.b64encode() ：

import hashlib
import hmac
import base64

base_string = "POST&https%3A%2F%2Fsecure.trademe.co.nz%2FOauth%2FRequestToken&oauth_callback%3Dhttp%253A%252F%252Fwww.website-tm-access.co.nz%252Ftrademe-callback%26oauth_consumer_key%3DC74CD73FDBE37D29BDD21BAB54BC70E422%26oauth_nonce%3D7O3kEe%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1285532322%26oauth_version%3D1.0%26scope%3DMyTradeMeRead%252CMyTradeMeWrite".encode()
KEY = b"3B61C8A3FF9F1F6C0DBE436F9B507E08EF&"

digest = hmac.new(KEY, base_string, hashlib.sha1).digest()
print(base64.b64encode(digest))
