Neo4j javascript驱动配置错误

Question

我一般是使用 Neo4j 的新手，但是 http 连接器上的 Neo4j CE 3.1 浏览器工作得非常顺利。现在我需要使用 JavaScript 来开发图形可视化，而驱动程序根本不起作用。我下载了 neo4j-javascript-driver-1.1，然后 npm 安装 npm WARN 可选跳过可选依赖：fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents)： npm WARN notsup 跳过可选依赖：fsevents@1.0.15 不受支持的平台：想要 {"os":"darwin","arch":"any"}（当前：{"os":"win32","arch": "x64"})

npm build (fine)
npm test (problems)

我能理解的是螺栓连接器需要配置，所以我添加到配置文件中以启用螺栓连接。这使无法连接的消息消失了。现在我遇到了这个问题：

我已在 Windows 10 命令提示符下尝试过此操作，并得到与 WebStorm 2016.3.2 内部相同的响应，

我在尝试 localhost:7687 时也收到以下响应，因为我收到无法连接的错误

not a WebSocket handshake request: missing upgrade

我猜这是因为它通过http连接，而这个端口是一个螺栓连接，只通过驱动程序。

我对 localhost:7474 浏览器的 http 连接（用户名和密码）进行了身份验证，感谢您对如何配置螺栓连接的身份验证的帮助，

提前致谢，

从错误中可以看出您用于登录 neo4j 的用户名和密码错误：

[ { code: 'Neo.ClientError.Security.Unauthorized',
   message: 'The client is unauthorized due to authentication failure.' } ]
