我正在使用neo4jdb-python包来查询Neo4j数据库.例如,考虑以下代码
import neo4j
connection = neo4j.connect("http://localhost:7474")
cursor = connection.cursor()
for i in cursor.execute("MATCH a RETURN a LIMIT 1"):
print i
但输出是元组的形式.即
({u'text': u'Stoyanov, S., Hoogveld, B., Kirschner, P.A., (). Mapping Major Changes to Education and Training in 2025, in JRC Technical Note JRC59079., Publications Office of the European Union: Luxembourg.', u'identifier': u'reference/lak/226'},)
如何以csv格式获得输出.这可以通过neo4j的Web视图实现.输出就像,
"{""text"":""Stoyanov, S., Hoogveld, B., Kirschner, P.A., (). Mapping Major Changes to Education and Training in 2025, in JRC Technical Note JRC59079., Publications Office of the European Union: Luxembourg."",""identifier"":""reference/lak/226""}"
但是我想通过客户端程序来实现它,因为我需要将它嵌入到另一个程序中.如果使用neo4jdb-python是不可能的,那么还有哪些其他选项可用.
解决方法:
该CSV实际上并非来自特定的API – 它在客户端被翻译成CSV格式.
$scope.exportCSV = (data) ->
return unless data
csv = new CSV.Serializer()
csv.columns(data.columns())
for row in data.rows()
csv.append(row)
这指的是CSV.coffee.我猜你应该可以在Python中做类似的事情,也许像using json.dumps这样：
> import json
> t = ({u'text': u'Stoyanov, S., Hoogveld, B., Kirschner, P.A., (). Mapping Major Changes to Education and Training in 2025, in JRC Technical Note JRC59079., Publications Office of the European Union: Luxembourg.', u'identifier': u'reference/lak/226'},)
> json.dumps(t)
'[{"text": "Stoyanov, S., Hoogveld, B., Kirschner, P.A., (). Mapping Major Changes to Education and Training in 2025, in JRC Technical Note JRC59079., Publications Office of the European Union: Luxembourg.", "identifier": "reference/lak/226"}]'
