将Neo4j连接到nodejs错误

Question

我正在尝试设置neo4j数据库，以便与javescript代码一起使用。当我运行我的代码时，我一直得到这个

PS C:\Users\futur\Documents\Coding\Neo4j>节点app.js本体解析器未定义扩展:提供扩展选项app.js:21:20服务器已启动GET / 304 37.114 ms -{ Neo4jError: getaddrinfo ENOTFOUND locthost locthost:7687 在新结果(C:\Users\futur\Documents\Coding\Neo4j\node_modules\neo4j-driver\lib\v1\result.js:200:15) at (C:\Users\futur\Documents\Coding\Neo4j\node_modules\neo4j-driver\lib\v1\result.js:73:19) at Session._run (C:\Users\futur\Documents\Coding\Neo4j\node_modules\neo4j-driver\lib\v1\session.js:122:14)(C:\Users\futur\Documents\Coding\Neo4j\node_modules\neo4j-driver\lib\v1\session.js:101:19) at C:\Users\futur\Documents\Coding\Neo4j\app.js:31:4 at Layer.handle request at next (C:\Users\futur\Documents\Coding\Neo4j\node_modules\express\lib\router\route.js:137:13) at Route.dispatch (C：\Users\futur\Documents)Coding\Neo4j\node_modules\express\lib\router\route.js:112:3) at Layer.handle request at C:\Users\futur\Documents\Coding\Neo4j\node_modules\express\lib\router\index.js:281:22 代码：'ServiceUnavailable'，名称：'Neo4jError‘}

下面是我的代码

var express         = require("express");
var path            = require("path");
var logger          = require("morgan");
// var cookieParser = require("cookie-parser");
var bodyParser      = require("body-parser");
var neo4j           = require("neo4j-driver").v1;

var app             = express();


// 
// <script src="lib/browser/neo4j-web.min.js"></script>


//view engine setup
app.set("views", path.join(__dirname, "views"));
app.set("view engine", "ejs");

app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extened: false}));
// app.use(cookieParser());
app.use(express.static(path.join(__dirname, "public")));

var driver = neo4j.driver("bolt://locthost", neo4j.auth.basic("neo4j", "test"));
var session = driver.session();

//home route
app.get('/', function(req, res){
    session 
        .run("MATCH (n) RETURN n")
        .then(function(result){
            result.records.forEach(function(records){
                console.log(records._fields[0]);
            });
        })
        .catch(function(error){
            console.log(error);
        });
    res.render("index");
});


app.listen(3000);
console.log('Server has started');

module.export = app;

我该怎么办？

您的bolt URI中可能有一个错误。

如果您的代码运行在与neo4j服务器相同的计算机上，请尝试将locthost更改为localhost。
