python - 如何使用 Tornado 通过 http POST 发送压缩文件

Question

我需要通过 HTTP 请求发送压缩的 JSON 文件

def create_gzip():
    with open('articoli.json', 'rb') as f_in, gzip.open('articoli.json.gz', 'wb') as f_out:
        shutil.copyfileobj(f_in, f_out)
    return open('articoli.json.gz', 'rb')

body = create_gzip()
headers = tornado.httputil.HTTPHeaders({"content-type": "application/zip charset=utf-8"})
request = tornado.httpclient.HTTPRequest("http://localhost:8889/variazione", method='POST', headers=headers, body=body)
http_response = http_client.fetch(request)

但是当我尝试这样做时，会出现以下错误:

 TypeError: Expected bytes, unicode, or None; got <type 'file'>

如何发送文件？有没有办法让请求接受 gzip？

实际上非常简单:传递给 HTTPRequest 的 body 必须是:

body=open('articoli.json.gz',"rb").read()
tornado.httpclient.HTTPRequest("http://localhost:8889/variazione", method='POST', 
                                                 headers=headers, body=body)
