I am using this function to uncompress the body or a HTTP response if it is compressed with gzip, compress or deflate.
def uncompress_body(self, compression_type, body):
if compression_type == 'gzip' or compression_type == 'compress':
return zlib.decompress(body)
elif compression_type == 'deflate':
compressor = zlib.compressobj(9, zlib.DEFLATED, -zlib.MAX_WBITS)
compressed = compressor.compress(body)
compressed += compressor.flush()
return base64.b64encode(compressed)
return body
However python throws this error message.
TypeError: a bytes-like object is required, not '_io.BytesIO'
on this line:
return zlib.decompress(body)
Essentially, how do i convert from '_io.BytesIO' to a bytes-like object?
Thanks
It's a file-like object. Read them:
>>> b = io.BytesIO(b'hello')
>>> b.read()
b'hello'
If the data coming in from body is too large to read into memory, you'll want to refactor your code and use zlib.decompressobj instead of zlib.decompress.
