node.js - FaunaDB 应用程序返回 401 但凭据很好

问题描述

我想尝试 FaunaDB，所以我做了一个 NodeJS 应用程序。我按照教程制作了一个类似 twitter 的应用程序。但是，当我尝试访问数据库时，我收到 403 未经授权的消息。我检查了我的安全密钥，但我仍然收到同样的错误。任何帮助，将不胜感激。

.env 文件：

KEY=randomString
PORT=5000

index.js：

require("dotenv").config();
const app = require("express")();
const faunadb = require("faunadb");

const client = new faunadb.Client({
    secret: process.env.KEY,
});

const {
    Paginate,
    Get,
    Select,
    Match,
    Index,
    Create,
    Collection,
    Lambda,
    Var,
    Join,
    Ref,
} = faunadb.query;

app.listen(5000, () => console.log(`API on http://localhost:${process.env.PORT}`));

app.get("/tweet/:id", async (req, res) => {
    try {
        const doc = await client.query(
            Get(
                Ref(
                    Collection("tweets"),
                    req.params.id
                )
            )
        )
        res.send(doc);

    } catch (err) {
        res.send(err)
    }
});

解决方案

像这样实例化客户端：

const client = new faunadb.Client({
  secret: process.env.KEY,
});

您正在应用一些默认参数，就好像您以这种方式编写代码一样（我仅指定最重要的参数）：

const client = new faunadb.Client({
  secret: process.env.KEY,
  domain: 'db.fauna.com',
  scheme: 'https',
});

如果您使用美国区域组、欧洲区域组或预览环境，“db.fauna.com”默认域将不适合您。

因此，您需要在构造函数中显式提供域参数。

对于美国地区组：

const client = new faunadb.Client({
  secret: process.env.KEY,
  domain: 'db.us.fauna.com',
  scheme: 'https',
});

对于欧盟地区组：

const client = new faunadb.Client({
  secret: process.env.KEY,
  domain: 'db.eu.fauna.com',
  scheme: 'https',
});

预览：

const client = new faunadb.Client({
  secret: process.env.KEY,
  domain: 'db.fauna-preview.com',
  scheme: 'https',
});

您可以在文档中阅读有关区域组的更多信息： https ://docs.fauna.com/fauna/current/api/fql/region_groups
