连接到 MongoDB 集合的问题

Question

我正在使用 axios 和 express.js API 连接到我的 mongo 数据库。我有一个适用于一个集合的 .get() 请求，不适用于任何其他集合。这当前将连接到数据库并可以访问称为用户的集合之一。我在同一个数据库下有另一个集合设置，称为任务，我的用户和任务设置方式相同，并且在代码中使用方式相同。用户可以连接到数据库（get、post），并且在调用 get 或 post 函数时任务无法连接到集合。在浏览器中查看 .get() API 请求时，它只是挂起，从不返回任何内容或完成请求。

任何帮助将不胜感激！

该项目位于 SCRUM-150 下的 GitHub 上。

Answer 1

您是否在代码中设置任何访问控制？

另请参阅此处的 mongoDB 文档： https://docs.mongodb.com/manual/core/collection-level-access-control/

Answer 2

这是我的解决方案： 在你的 app.js 中，有这个：

let mongoose = require('mongoose');

mongoose.connect('Your/Database/Url', {
    keepAlive     : true,
    reconnectTries: 2,
    useMongoClient: true
});

在你的路线上有这个：

let mongoose = require('mongoose');
let db = mongoose.connection;
fetchAndSendDatabase('yourCollectionName', db);

function fetchAndSendDatabase(dbName, db) {
    db.collection(dbName).find({}).toArray(function(err, result) {
        if( err ) {
            console.log("couldn't get database items. " + err);
        }
        else {
            console.log('Database received successfully');
        }
    });
}
