我正在使用neo4jdb-python包來查詢Neo4j數(shù)據(jù)庫.例如,考慮以下代碼

import neo4j

connection = neo4j.connect("http://localhost:7474")

cursor = connection.cursor()

for i in cursor.execute("MATCH a RETURN a LIMIT 1"):

print i

但輸出是元組的形式.即

({u'text': u'Stoyanov, S., Hoogveld, B., Kirschner, P.A., (2010). 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格式獲得輸出.這可以通過neo4j的Web視圖實(shí)現(xiàn).輸出就像,

"{""text"":""Stoyanov, S., Hoogveld, B., Kirschner, P.A., (2010). 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""}"

但是我想通過客戶端程序來實(shí)現(xiàn)它,因?yàn)槲倚枰獙⑺度氲搅硪粋€(gè)程序中.如果使用neo4jdb-python是不可能的,那么還有哪些其他選項(xiàng)可用.

解決方法:

該CSV實(shí)際上并非來自特定的API – 它在客戶端被翻譯成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)

這指的是CSV.coffee.我猜你應(yīng)該可以在Python中做類似的事情,也許像using json.dumps這樣：

> import json

> t = ({u'text': u'Stoyanov, S., Hoogveld, B., Kirschner, P.A., (2010). 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., (2010). 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"}]'
