RuntimeError: inconsistent AsyncHTTPClient cache

代码如下:

import tornado.httpclient

http_client = tornado.httpclient.HTTPClient()
response = http_client.fetch("www.baidu.com")
print(response.body)
http_client.close()

完整报错如下:

Traceback (most recent call last):
  File "test.py", line 8, in <module>
    response = http_client.fetch("www.baidu.com")

解决方案:

response = http_client.fetch("www.baidu.com")

改为:

response = http_client.fetch("http://www.baidu.com")
