执行报错

[jjustwin]

ft1.1: ******* 正在执行用例 ->event_login_001 *********
请求方式: post，请求URL: http://192.168.250.44:6223/xxx/sys/login
请求参数:
post请求body类型为：json ,body内容为：{"t":1584687365417,"departmentNo":"440682111","username":"admin","password":"xxxxxx","uuid":"","captcha":""}
invalid syntax (, line 1)
Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\lib\site-packages\ddt.py", line 151, in wrapper
return func(self, *args, **kwargs)
File "E:\API_auto\DemoAPI\testcase\testAPI.py", line 35, in test_api
self.result = re.json()
AttributeError: 'NoneType' object has no attribute 'json'

这个是report里报的错，看样子是请求失败了，但 不知道为何失败

这个接口postman，还有我单独使用r = requests.post(url, headers=h,data=data_body)都正常请求

另外，控制台的报错：
C:\ProgramData\Anaconda3\python.exe E:/API_auto/DemoAPI/run_demo.py

失败: server_hostname cannot be an empty string or start with a leading dot.
