师傅，有个问题请教下

能正常扫描但是输出有问题，还有扫描完成之后报错 Masscan completed successfully.
Traceback (most recent call last): File "MNScan.py", line 114, in run_masscan(args.output_file_path, args.target, args.ports, args.rate) File "MNScan.py", line 86, in run_masscan ip_ports_mapping = parse_masscan_output(masscan_output) File "MNScan.py", line 14, in parse_masscan_output results = json.loads(masscan_output) File "/usr/lib/python3.8/json/init.py", line 357, in loads return _default_decoder.decode(s) File "/usr/lib/python3.8/json/decoder.py", line 337, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib/python3.8/json/decoder.py", line 355, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 3 column 1 (char 155) 上面是扫描完成之后的报错，下面是输出结果不合适

我运行的命令是python3 MNScan.py -i 4.x.x.x -p 5003 -o /home/out.txt 我的python文件内容是 `import subprocess import argparse import re import json from collections import defaultdict import concurrent.futures

这个是你的masscan扫描结果最后多了一个逗号引起的，导致json解析错误，我的masscan输出的json最后没有这个逗号，可能我们masscan的版本不一样，我更新了代码，在代码里加了判断过滤掉这个逗号，我试了可以正常使用了，另外之前程序里没有判断masscan扫描结果是否为空，会导致异常退出程序，我更新后加入了判断，可以更加明了显示结果。
