python操作solr

solr接收Http请求，所以使用requests库操作solr就可以

添加

    data = {"add": {"doc": params, "commitWithin": 1000}}
    headers = {"Content-type": "application/JSON"}
    re = requests.post(url=url, data=json.dumps(data),
                       headers=headers)

查询

    params = list()
    params.append(('q', "id:" + id))
    response = requests.post(url=url, data=params)

很多时候请求文本存在特殊字符，所以需要转义(或者用括号括起来)

    def escape_query_chars(s):
    escape_chars = set(
            ('\\', '+', '-', '!', '(', ')', ':', '^', '[', ']', '\"', '{', '}', '~', '*', '?', '|', '&', '', '/', ' ','\t'))
        arr = [c for c in s if (c not in escape_chars)]
        return "".join(arr).replace("\xe3\x80\x80", "")
