如何使用pythoncan修复损坏的.blf文件（来自Vector软件）

Question

这与this question类似，只是我希望以一个新的BLF文件而不是.csv文件结束。我这样做是为了删除BLF文件中的一个损坏的对象，它阻止我将其导入Vector的软件中。我想有办法直接通过can.io.blf公司.BLFReader'由BLFReader直接生成到BLFWriter的类对象，但我很难弄清楚如何生成。下面的示例代码应该有助于解释我想要实现的功能：

import can


filename_in = "corrupted.blf"
log = can.io.BLFReader(filename_in)
filename_out = "cleaned.blf"
can.io.BLFWriter(filename_out,log)

Answer 1

我的解决方案是：

def BLFRepair(filename_in, filename_out):
""" Repairs a corrupted Vector .blf fileself.
Args:
    filename_in (str): Filename of input corrupted file.
    filename_out (str): Filename to save repaired file with.
"""
cleaned_log=BLFReader(filename_in)   # ignores errors
logger=BLFWriter(filename_out)
for msg in cleaned_log:
    logger.on_message_received(msg)

logger.stop()
