Python http.client.Incomplete Read（0字节读取）错误

Question

我在论坛上看到了这个错误，并通读了答案，但我仍然不明白它是什么或如何解决它。我从互联网上从16k链接中获取数据，我的脚本从每个链接中获取类似的信息，并将其写入一个.csv，在出现此错误之前会写入一些日期。

Traceback (most recent call last): 
File "/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 541, in _get_chunk_left 
    chunk_left = self._read_next_chunk_size()

    return int(line, 16)

During handling of the above exception, another exception occurred:

http.client.IncompleteRead: IncompleteRead(17891 bytes read) 

我想知道：
1）这个错误是什么意思？
2）我如何防止它？

Answer 1

尝试导入：

from http.client import IncompleteRead 

，并在脚本中添加此：

except IncompleteRead: 
    # Oh well, reconnect and keep trucking 
     continue
