我是Node.js中的新手，并尝试使用API令牌访问Grafana。 我按照Grafana page的说明创建了一个API令牌。
但是，我不知道如何通过我的node.js代码进行API调用来访问我的grafana页面的本地服务器。此外，我有一个本地登录页面，使用mongoDB来管理用户。
如何进行Node.js API调用以访问grafana页面的本地服务器？
请帮帮我..我在这方面遇到了困难.. 如果你想让我显示代码，我可以在这里编辑..

API调用是使用HTTP请求进行的。您可以使用npm的request包。
来自文档：
您在授权标头中的所有请求中使用令牌，如下所示： 获取http://your.grafana.com/api/dashboards/db/mydash HTTP / 1.1 接受：application / json 授权：bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk
示例（我正在使用request-promise，但您可以使用任何您想要的内容）：
let request = require('request-promise');
let url = `http://your.grafana.com/api/dashboards/db/mydash`;
//Obviously replace this with your token
let myToken = `eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk`;
request.get(url).auth(null, null, true, myToken).then(res=> { ... });
// or
request.get(url, {
auth: {
bearer: myToken
}
}).then(res=> { ... });
