操作系统和python版本如下：

$ cat /etc/issue
Ubuntu 18.04 LTS \n \l

$ python -V
Python 2.7.15rc1

怎么才能让测试通过呀？

[fzlee]

这边通过库以及openssl的sha函数分别对字符串进行摘要， 比较结果， 如果相同则测试通过。

result1 = alipay._sign("hello\n")
result2 = subprocess.check_output(
            "echo hello | openssl sha -sha1 -sign {} | openssl base64".format(
                self._app_private_key_path
), shell=True).decode("utf-8")

你试试在命令行下执行 openssl --help 试试， 看看有没有sha这个子命令

[waketzheng]

把第104行和地116行修改如下后，测试通过了：

-            "echo hello | openssl sha -sha1 -sign {} | openssl base64".format(
+            "echo hello | openssl sha1 -sign {} | openssl base64".format(

-            "echo hello | openssl sha -sha256 -sign {} | openssl base64".format(
+            "echo hello | openssl sha256 -sign {} | openssl base64".format(

应该是实用的openssl版本不同导致的， 我改成了

openssl dgst -sha1/256
