我是neo4j的新手，我试图通过node4js将数据插入到neo4j数据库中，但是出现了任何错误都可以解决这个问题。

var express=require("express");
var app=express();
var neo4j=require('neo4j');
var neo4jDB = new neo4j.GraphDatabase('http://localhost:7474/browser');
var crypto=require('crypto');
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: true }))
var appSecret=process.env.APP_SECRET;
app.get('/',function (req,res){
    res.send("Hello World");
})

app.get('/index',function(req,res){
    res.sendFile('test.html',{'root': __dirname });
})

app.post('/insert',function (req,res){
     var email = req.body['email'];
     var password = req.body['password'];
          var query = [
             'CREATE (user:User {newUser})',
                 'RETURN user'
            ].join('\n');
     var params = {
         newUser: {
           email: email,
           password: password,
         }
     };                         
     neo4jDB.cypher({
       query: query,
          params: params
       }, 
       function(err,user){
         if(err) throw err;
         console.log(user);
         res.send("Record has been inserted")
     });
})
app.listen(8000);

Your Neo4j server requires an authentication (the default setting), so you have to provide a username and a password to connect to it.

Neo4j服务器需要一个身份验证(默认设置)，因此必须提供一个用户名和密码来连接它。

According to the documentation for the "neo4j" npm package, this is done in the URL of the Neo4j server:

根据“neo4j”npm包的文档，这是在neo4j服务器的URL中完成的:

var db = new neo4j.GraphDatabase('http://username:password@localhost:7474');
