Stackexchange API 编码

Question

我正在为 Stackexchange API 编写以下装饰器：

    class StackOverflowHandler(tornado.web.RequestHandler):

            def get(self, look_up_pattern):
                url = "https://api.stackexchange.com/2.2/search?order=desc&sort=votes&intitle=%s&site=stackoverflow"
                with urllib.request.urlopen(url % look_up_pattern) as so_response:
                response = so_response.read()
            print(response)
            self.write(response)

    application = tornado.web.Application([
        (r"/search/(.*)", StackOverflowHandler),
    ])

作为response，我得到字节流：

b'\x1f\x8b\x08\x00\x00\x00\x00\x00\x04\x00\xb5\\\x0b\x93\xa3F\x92\xfe+u\xe...

问题是谁编码响应？什么是正确的 Unicode 来解码？我检查了 utf-8、utf-16、zlib.decompress 等。它没有帮助。

Daniel Roseman 链接到的答案的相关部分是这样的：

if response.info().get('Content-Encoding') == 'gzip':
    buf = StringIO( response.read())
    f = gzip.GzipFile(fileobj=buf)
    data = f.read()

换句话说，编码应该是response.info().get('Content-Encoding')
