Decide what byte causes the zlib inflate decompression operation

Question

I got the following code which suppose to decompress a simple inflated data.

import zlib
print zlib.decompress(content)

It crashes with the following error

zlib.error: Error -3 while decompressing data: invalid distance too far back

I want to be able to log the index of the exact byte (the first one) that causes the decompression to fail... Is that possible?

Answer 1

使用decompressobj一个decompressor对象，并使用decompress一次将其送入一个字节，直到失败并出现错误。
