Question

这可能是显而易见的，但不是我：我有一个JSON对象有一个包含字符串化JSON的属性（不要问为什么，它只是必须这样）当我UNWIND对象并抓住该属性（键）有没有办法转换为内联到密码查询的地图？

WITH {input} AS S
UNWIND S AS stat
WITH stat.key.str as K, stat.value as value
UNWIND K as key
RETURN key, value

返回：

key                                                                          value    

-----------------------------------------------------------------------------------------  
{"role":"consumer","ipproto":"TCP","l7proto":"tcp:80","port":80,"dir":""}      156        
{"role":"consumer","ipproto":"TCP","l7proto":"tcp:443","port":443,"dir":""}    223        
{"role":"consumer","ipproto":"TCP","l7proto":"MSN","port":1863,"dir":""}    106208

是否可以在key中解析/加载字符串值以将其作为地图读取，或者我是否必须在cypher查询之外将其转换？

道歉 - 我对neo4j和cypher都很赞不绝口......

您需要APOC Procedures，特别是var table = document.querySelector('.table'); table.style.overflowY='hidden';将其转换为Cypher地图。以下是您将如何使用它：

apoc.convert.fromJsonMap()

neo4j / cypher：将字符串内联转换为地图
