python - 带有StringIO的Python3错误: initial_value must be str or None,

将代码从python2移植到3时，从URL读取时出现此错误

import urllib
import json
import gzip
from urllib.parse import urlencode
from urllib.request import Request


service_url = 'https://babelfy.io/v1/disambiguate'
text = 'BabelNet is both a multilingual encyclopedic dictionary and a semantic network'
lang = 'EN'
Key  = 'KEY'

    params = {
        'text' : text,
        'key'  : Key,
        'lang' :'EN'

        }

url = service_url + '?' + urllib.urlencode(params)
request = Request(url)
request.add_header('Accept-encoding', 'gzip')
response = urllib.request.urlopen(request)
if response.info().get('Content-Encoding') == 'gzip':
            buf = StringIO(response.read())
            f = gzip.GzipFile(fileobj=buf)
            data = json.loads(f.read())

在这一行抛出异常

buf = StringIO(response.read())

如果我使用python2，它可以正常工作。

最佳答案

response.read()返回bytes的实例，而 StringIO 是仅用于文本的内存流。请改用 BytesIO 。
