网站建设金手指15网站建设小图标

px4的日志文件一直通过pyulog做解析 但是发现有的时候会出现错误，解析不了，使用网站解析也会失败，但是这把数据很重要所以想办法必须解决，报错如下

zzh@zzh-System-Product-Name:~/Desktop/log/log223/log42$ ulog_info -m MESSAGE log_42_2025-2-23-17-08-34.ulg

定位问题，我是用linux，找到运行的包pyulog包，在python3.8下面
打开这个core.py文件
找到报错的这个函数_parse_string

@staticmethoddef parse_string(cstr):"""wrapper for _parse_string withparametrized exception handling"""ret = ''if _RUNNING_PYTHON3 and ULog._disable_str_exceptions:ret = _parse_string(cstr, 'ignore')else:ret = _parse_string(cstr)return ret

经过deepseek指点，把else后面的分支改成

        else:# 默认使用 'replace' 替换无法解码的字节ret = _parse_string(cstr, 'replace')

保存后，再次运行pyulog命令，全部解析出来了
