FaunaDB 应用程序返回 401 但凭据很好

如何解决FaunaDB 应用程序返回 401 但凭据很好

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像 twitter 这样的应用程序。但是，当我尝试访问数据库时，收到 403 未经授权的消息。我已经检查了我的安全密钥，但仍然出现相同的错误。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)
    }
});

解决方法

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，就像您以这种方式编写代码一样（我只指定了最重要的参数）：

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

如果您使用美国地区组、欧盟地区组或预览环境，“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',});

对于欧盟地区组：

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

预览：

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