在 package.json 文件中添加 MongoDB 和 Mongoose 依赖，将 mLab 数据库的 URI 作为 MONGO_URI 变量存储在私有 .env 文件中。然后require('mongoose')，使用mongoose.connect()命令来连接数据库。

mongoose.connect(<Your URI>, { useNewUrlParser: true, useUnifiedTopology: true }); 

Instructions

Tests

tests:
  - text: "在 package.json 文件中应该有 'mongodb' 依赖。"
    testString: 'getUserInput => $.get(getUserInput(''url'') + ''/_api/file/package.json'').then(data => { var packJson = JSON.parse(data);     assert.property(packJson.dependencies, ''mongodb''); }, xhr => { throw new Error(xhr.responseText); })'
  - text: "在 package.json 文件中应该有 'mongoose' 依赖。"
    testString: 'getUserInput => $.get(getUserInput(''url'') + ''/_api/file/package.json'').then(data => { var packJson = JSON.parse(data);     assert.property(packJson.dependencies, ''mongoose''); }, xhr => { throw new Error(xhr.responseText); })'
  - text: "'mongoose' 应该已经连接数据库。"
    testString: 'getUserInput => $.get(getUserInput(''url'') + ''/_api/is-mongoose-ok'').then(data => {assert.isTrue(data.isMongooseOk, ''mongoose is not connected'')}, xhr => { throw new Error(xhr.responseText); })'
