【标题描述】手动构造tcpline.txt格式异常数据，get_entities接口会有Traceback打印
【环境信息】
[root@openEuler spider]# uname -r
5.10.0-5.8.0.22.oe1.x86_64
[root@openEuler spider]# rpm -qa | grep gala-spider
python3-gala-spider-v1.0.2-2.oe1.x86_64
gala-spider-v1.0.2-2.oe1.x86_64
【问题复现步骤】
1，手动构造tcpline.txt数据，且数据错误非jason格式，使用curl -X 'GET' 'http://0.0.0.0:11115/gala-spider/api/v1/get_entities' -H 'accept: application/json' 获取实信息
【预期结果】
数据异常应该增加可靠性，不能导致接口500
【实际结果】
