关于接口测试签名和验签不通过的疑问.希望高手指点,谢谢！

是这样的  我这个代码是测试[登录接口],需要把密码通过aes加密,然后进行签名.在最后调用登录接口,具体见以下截图.但是一直提示签名失败.麻烦大神帮我看看,万分感谢.
接口文档相关信息我截图如下:（我就是按照这个步骤来弄的）

代码如下:

import unittest
import hashlib
import requests
import os, sys
from Crypto.Cipher import AES
from Crypto import Random
parentdir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, parentdir)
# from db_fixture import test_data

app_master_secret="F0CED9E71C0D2798CFCEF0D3086F60";

#测试b2c登录接口
class b2cTest(unittest.TestCase):
def setUp(self):
      self.base_url = "http://test.xxxxx.com/api/login/"

def tearDown(self):
      print (self.result)

def test_example(self):
      #加密
      key = b"7BD87CCADE73F50B4918DCAD082938"  # 16-bytes password
      iv = Random.new().read(AES.block_size)
      self.key = hashlib.sha256(key).digest()
      obj = AES.new(self.key,AES.MODE_CBC,iv)
      password_chushi = "a12345678"
      password_chushi.encode("utf-8")
      data = self.pkcs7padding(password_chushi)
      password_value=obj.encrypt(data)

      myParameters={'username': '15600002746', 'password': str(password_value)}

      print(myParameters['username'])
      print(myParameters['password'])

      #签名
      md5 = hashlib.md5()
      sign_str = "post" + str(self.base_url) + str(myParameters['username']) + str(myParameters['password']) + app_master_secret # 拼接字符串
      sign_str1 = sign_str.upper();  # 转换为大写
      sign_bytes_utf8 = sign_str1.encode(encoding="utf-8")
      md5.update(sign_bytes_utf8)
      self.sign_md5 = md5.hexdigest()

      #组装my_parameters
      payload={"client-type": 2,
               "device":"111",
               "device-identifier":"222",
               "app-version":"333",
               "channel":"444",
               "os-version": "555",
               "timestamp":"666",
               "my-parameters":str(myParameters),
               "sign":self.sign_md5
               }

      #发送请求
      r = requests.post(self.base_url,data=payload)
      print (data)
      self.result = r.json()
      print(self.result['retCode'])
      print (r.status_code)
      print (self.result)
      self.assertEqual(self.result['retCode'], 200)

def pkcs7padding(self, data):
      bs = AES.block_size
      padding = bs - len(data) % bs
      padding_text = chr(padding) * padding
      return data + padding_text

if __name__ == '__main__':
unittest.main()

服务器返回:{'retMsg': '签名验证失败', 'retCode': '40000'}
