Excel中加入一列：extractor

值如下：

{"token":"$..token","user_id":"$..user_id","username":"$..username"}

 

测试用例函数中获取：

extractor = info['extractor']

if extractor:
    extractor = json.loads(extractor)
    for key, value in extractor.items():
        setattr(Handler, key, jsonpath(resp_data, value)[0])


设置类属性，后续用re正则匹配关联用例
