在用python向Solr添加数据时遇到麻烦吗？

Question

我正在使用python3.4.3并将一些文档添加到Solr(5.2.1)中。以下代码直接来自晒黑的文档：

import sunburnt

si=sunburnt.SolrInterface("http://localhost:8983/solr/")

document = {"id":"0553573403",
        "cat":"book",
        "name":"A Game of Thrones",
        "price":7.99,
        "inStock": True,
        "author_t":
        "George R.R. Martin",
        "series_t":"A Song of Ice and Fire",
        "sequence_i":1,
        "genre_s":"fantasy"}

si.add(document)

当我运行上面的命令时，我得到以下信息：

NameError                                 Traceback (most recent call last)
<ipython-input-1-1008a9ce394f> in <module>()----> 1 import sunburnt
  2 
  3 si= sunburnt.SolrInterface("http://localhost:8983/solr/")
  4 
  5 document = {"id":"0553573403",

/Users/rmohan/venv_py3/lib/python3.4/site-packages/sunburnt/__init__.py in <module>()
  1 from __future__ import absolute_import
  2 
----> 3 from .strings import RawString
  4 from .sunburnt import SolrError, SolrInterface
  5 

/Users/rmohan/venv_py3/lib/python3.4/site-packages/sunburnt/strings.py in <module>()
  2 
  3 
----> 4 class SolrString(unicode):
  5     # The behaviour below is only really relevant for String fields rather
  6     # than Text fields - most queryparsers will strip these characters out

NameError: name 'unicode' is not defined

因此，我使用pysolr尝试了相同的文档，如下所示：

import pysolr
solr = pysolr.Solr('http://localhost:8983/solr/', timeout=10)

document = [{"id":"0553573403",
        "cat":"book",
        "name":"A Game of Thrones",
        "price":7.99,
        "inStock": True,
        "author_t":
        "George R.R. Martin",
        "series_t":"A Song of Ice and Fire",
        "sequence_i":1,
        "genre_s":"fantasy"}]

solr.add(document)

其中规定如下：

/Users/rmohan/venv_py3/lib/python3.4/site-packages/pysolr.py in _scrape_response(self, headers, response)
443         dom_tree = None
444 
--> 445         if response.startswith('<?xml'):
446             # Try a strict XML parse
447             try:

TypeError: startswith first arg must be bytes or a tuple of bytes, not str

我做了一些谷歌搜索，但没有找到一个明确的答案，如何解决unicode或字节问题的输入。我尝试将字符串转换为字节和unicode，但似乎没有什么工作。

如果有人知道在SOLR中插入文档的更好方法，请进行共享。任何帮助都将不胜感激。

Answer 1

我想出来了，pysolr.py的文件

if response.startswith('<?xml'):

需要更改为

if response.startswith(b'<?xml'):
