python3 使用unittest时，提示：ResourceW

1. ResourceWarning信息

用例执行成功，但是提示：

ResourceWarning: unclosed <ssl.SSLSocket fd=312, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('x.x.x.x', 52978), raddr=('x.x.x.x', 443)>
ResourceWarning: Enable tracemalloc to get the object allocation traceback

2. 解决

def setUp(self):
     warnings.simplefilter('ignore', ResourceWarning)
