Traceback (most recent call last):

  File "C:\python\iCrawler.py", line 44, in <module>

    crawler(sites)

  File "C:\python\iCrawler.py", line 24, in crawler

    resp,content = h.request(site,'GET')

  File "C:\python\lib\site-packages\httplib2\__init__.py", line 1089, in request

    (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey)

  File "C:\python\lib\site-packages\httplib2\__init__.py", line 874, in _request

    (response, content) = self._conn_request(conn, request_uri, method, body, headers)

  File "C:\python\lib\site-packages\httplib2\__init__.py", line 859, in _conn_request

    content = _decompressContent(response, content)

  File "C:\python\lib\site-packages\httplib2\__init__.py", line 318, in _decompressContent

    content = zlib.decompress(content)

zlib.error: Error -3 while decompressing data: incorrect header check

解决办法:

参考：http://code.google.com/p/httplib2/issues/detail?id=69

修改：File "C:\python\lib\site-packages\httplib2\__init__.py", line 318, in _decompressContent

    改为：content = zlib.decompress(content,16+zlib.MAX_WBITS)

    结果：失败

    改为：content = zlib.decompress(content, -zlib.MAX_WBITS)
