用Python 生成中通的签名

Question

可以测试的签名生成工具地址：https://open.zto.com/#/Console?type=sign 

第一步：待签名字符串=请求参数+appSecret

{"billCodes":["202088881852"],"siteId":"2172"}zto123456

第二步：utf8Bytes= 使用UTF-8编码成byte数组(待签名字符串)

[123, 34, 98, 105, 108, 108, 67, 111, 100, 101, 115, 34, 58, 91, 34, 50, 48, 50, 48, 56, 56, 56, 56, 49, 56, 53, 50, 34, 93, 44, 34, 115, 105, 116, 101, 73, 100, 34, 58, 34, 50, 49, 55, 50, 34, 125, 122, 116, 111, 49, 50, 51, 52, 53, 54]

第三步：md5bytes = md5(utf8Bytes)

[9, 123, -14, 37, 119, -64, -56, 69, -115, -110, -26, -122, 67, -111, -70, -7]

第四步：x-datadigest=base64Str(md5bytes)

步骤可以用Python进行实现  如果不行结果用Python实现也行

Answer 1

import base64
import hashlib
import json
a = {"billCodes":["202088881852"],"siteId":"2172"}
b = 'zto123456'
c = json.dumps(a, separators=(',', ':'))+b
utf8Bytes = c.encode('utf8')
md5bytes = hashlib.md5(utf8Bytes).digest()
xdatadigest=base64.b64encode(md5bytes)
print(xdatadigest)
