                问题描述

                我需要在 PHP 中运行这种类型的查询:

                I need to run this type of queries in PHP:

                START n = node($thisUser), m = node($userId)
                MATCH n-[r:RATED]->m
                WHERE r.skillId = $id
                RETURN id(r)
                

                单个页面中有很多(~30).由于它使用 REST,因此运行时间不适用(~5-10 秒).所以我试图将它们分批发送,但我找不到任何方法来通过 REST 作为单批操作发送实际的密码查询.

                There are a lot of them for a single page (~30). Since it's using REST, the run-time comes out not applicable (~5-10 seconds). So I'm trying to send them in a single batch but I cannot find any method to send actual cypher queries through REST as operations in a single batch.

                有办法吗?

                推荐答案

                您是否尝试过以下方法?

                Have you tried the following?

                a) 交易休息资源
                b) 批处理多次调用/db/data/cypher 资源通过 /db/data/batch 资源,在有效载荷中带有 "to":"/cypher"
                c) 传递集合而不是单个值作为参数

                a) the transactional rest resource
                b) batching multiple calls to the /db/data/cypher resource via the /db/data/batch resource, with "to":"/cypher" in the payload
                c) passing collections instead of single values as parameters
