1.发送带有对象数组的http帖子到服务器
[{id:1, title: ‘one’},
{id:2, title:’two’}]
2.在服务器上接收帖子并使用bolt
批量插入neo4j let data = req.body;
//set up bolt
let db = require('neo4j-driver').v1;
let driver = db.driver('bolt://localhost', db.auth.basic('neo4j', ’neo4j’));
let session = driver.session();
3。设置执行语句
// start transaction
for(var i=0; i>data.length; i++) {
//add CREATE statements to bolt session ???
"CREATE (r:Record {id:1, title:'one'})"
"CREATE (r:Record {id:2, title:'two'})"
...
}
//execute session.run(???);
//stop transaction

在步骤3中,您可以将整个输入list
(来自步骤1)作为参数传递。 (但是,如果输入列表很长,则应将其拆分为较小的批次 - 例如每个10,000个项目。)
例如:
session
.run(
"UNWIND {list} AS i CREATE (:Record {id: i.id, title: i.title})",
{ list: list })
.then(function(result){
// Use the result ...
session.close();
})
.catch(function(error) {
console.log(error);
});
