MongoServerError：不允许用户在 [genius-car.service] 上执行操作 [find]

Question

我试图学习 MongoDB CRUD 操作以及 node express js

当我尝试 go 'http://localhost:5000/service' 它抛出以下错误：

 D:\Projects_WebDev\BackEnd\server-genius-car-service\node_modules\mongodb\lib\cmap\connection.js:207
                    callback(new error_1.MongoServerError(document));
                             ^

MongoServerError: user is not allowed to do action [find] on [genius-car.service]

}
[nodemon] app crashed - waiting for file changes before starting...

代码：`

async function run() {
    try {
        await client.connect();
        const serviceCollection = client.db('genius-car').collection('service');

        app.get('/service', async (req, res) => {
            const query = {};
            const cursor = serviceCollection.find(query);
            const services = await cursor.toArray();
            res.send(services)
        });


    } finally {
        //
    }

}
run().catch(console.dir);`

Answer 1

如果您收到错误“用户不允许执行操作 [插入]。在您的 mongoDb 帐户中，导航到数据库访问，然后单击尝试访问的用户的编辑按钮，导航到特殊权限并单击“添加特殊权限" select 角色选项并将角色更改为 "readWriteAnyDatabase"

Answer 2

请按照以下步骤解决此问题：

1. 登录您的 MongoDB Atlas 帐户
2. 单击数据库访问>数据库用户>编辑特定用户的操作>特定权限>添加特定权限> readWriteAnyDatabase （选择角色）>更新用户

完成这些步骤后，您将需要再次运行服务器并重新加载“http://localhost:5000/service”页面。 如果您正确遵循所有步骤，那么它将起作用。
