Question

我有一个Feathers.js后端，我一直在尝试使用ArangoDB data-adapter进行配置。我的数据库仅使用默认的用户名，空白密码和名为test的数据库，所有这些都在环境变量中设置。

ARANGODB_HOST="127.0.0.1"
ARANGODB_PASSWORD=""
ARANGODB_USERNAME="root"
ARANGODB_PORT=8529
ARANGODB_DB="test"

启动节点服务器时，出现以下错误

info: Feathers application started on http://localhost:3030
error: Unhandled Rejection at: Promise

似乎数据库未正确连接到Feathers.js或正在拒绝连接。我已经能够使用节点cli直接与ArangoDB接口，所以我认为这不是权限问题。该错误来自arangodb.js的最后一行，但我不知道是什么原因导致了此错误，并且在网上搜索解决方案并没有发现任何问题。

我有以下文件：

/src/arangodb.js

const Database = require('arangojs').Database;

module.exports = function () {
  const app = this;
  const config = app.get('arangodb');
  const promise = dbConnect(config);

  app.set('arangoClient', promise);
};

function dbConnect (options = {}) {
  const host = options.host || process.env.ARANGODB_HOST;
  const port = options.port || process.env.ARANGODB_PORT;
  const databaseName = options.database || process.env.ARANGODB_DB;

  const basicAuth = options.basicAuth || {};
  const username = basicAuth.username || process.env.ARANGODB_USERNAME;
  const password = basicAuth.password || process.env.ARANGODB_PASSWORD;

  const url = `${host}:${port}`;

  const db = new Database(url);
  db.useDatabase(databaseName);
  if (username) db.useBasicAuth(username, password);

  return new Promise((resolve, reject) => {
    db.get()
      .then(() => resolve(db))
      .catch(err => reject(err));
  });
}

/src/app.js

const path = require('path');
const favicon = require('serve-favicon');
const compress = require('compression');
const helmet = require('helmet');
const cors = require('cors');

const feathers = require('@feathersjs/feathers');
const configuration = require('@feathersjs/configuration');

const app = express(feathers());

app.configure(sequelize);

// Configure other middleware (see `middleware/index.js`)
app.configure(middleware);

const arangodb = require('./arangodb');
app.configure(arangodb);
// Configure a middleware for 404s and the error handler
app.use(express.notFound());
