如何使用python-can修复损坏的.blf文件(来自矢量软件)

Question

这类似于this question，除了我想以一个新的BLF文件而不是一个.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，该对象阻止我将其导入到Vector的软件中。我想有一种方法可以直接将BLFReader生成的'can.io.blf.BLFReader‘类对象直接传递给BLFWriter，但是我想不出该怎么做。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

以下是我的解决方案：

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()
