from Cryptodome.PublicKey import RSA
from base64 import b64encode, encodebytes
from Cryptodome.Signature import pkcs1_15, PKCS1_v1_5
from Cryptodome.Hash import SHA256
import random
import string
import time


def get_sign(sign_str):
    path = r'..\apiclient_key.pem'
    rsa_key = RSA.importKey(open(path).read())
    signer = pkcs1_15.new(rsa_key)
    digest = SHA256.new(sign_str.encode('utf-8'))
    sign = b64encode(signer.sign(digest)).decode('utf-8')

    return sign

结果就是 'message': '错误的签名，验签失败'

得到的就是不正确我个人感觉是计算签名值不正确。有没有可以参照的有大佬知道么，给指点下感谢。
