Get operations

Get local folders and notes

• http://localhost:3000/api/note/local-folder-notes-get
• Function: get the user's local folder list and note list
• No parameter needed

1. Environment

• Node.js

  Server will run in port 3000 (i.e. localhost:3000)

• MongoDB

  完全使用默认配置

  • 保证 MongoDB daemon 运行在 port 27017
  • 不设置数据库用户名、密码
  • 运行 server 后，会自动创建名为 note_squared 的数据库，可使用MongoDB Compass查看

2. Run Server

cd /note-squared/server

# 安装依赖
npm install

# 使用 nodemon 运行 server（如果修改 server 代码，会自动 restart）
npm run dev

# OR 使用以下命令（如果修改 server 代码，不会自动 restart）
npm run start

3. 其他注意事项

• 如何获得一个带有 admin 权限的账号？

  现在无法直接注册带有 admin 权限的账号了，需要手动修改数据库: users => role，手动改为admin / normal

• 注册时，需要验证邮箱吗？

  目前调用获取邮箱验证码的API后，验证码会直接返回给前端，所以即使填了假邮箱也没事。

  如果需要测试邮件是否真的能发送，找到server/app/router/user/register_emailVerificationCode.js文件中以下代码：

  // send verification email
  // (temporarily removed)
  //await nodemailer.sendVerificationCode(_email, _email, _verificationCode)

  删掉最后一行的注释即可。

get folders and notes:

[
    {
        "folder_id":"6257bde2ae6b2d0f2d28250c",
        "folder_title": "folder 1",
        "folder_name": "1",   // created by frontend automatically, should be posted to backend when creating a new folder
        "note": [
            {
                "note_id": "12345",
                "note_title": "article title",
                "note_description": "balabala",
                "mode": "public/privacy" 
                // other infomation: liked num, comments num, ... （optional）
            },
            {
                "note_id": "123456",
                "note_title": "article title",
                "note_description": "balabala",
                "mode": "public/privacy"
            }
        ]
    },
    {
        "folder_id":"6257bde2ae6b2d0f2d28250d",
        "folder_title": "folder 2",
        "folder_name": "2", 
        "note":[]
    }
]

get folders

[
    {
        "folder_id":"6257bde2ae6b2d0f2d28250c",
        "folder_title": "folder 1",
        "folder_name": "1",   // created by frontend automatically, should be posted to backend when creating a new folder
    },
    {
        "folder_id":"6257bde2ae6b2d0f2d28250d",
        "folder_title": "folder 2",
        "folder_name": "2", 
    }
]

implmentation suggestion
change the "/note/local-folder-notes-get" method to be post
according to different params:
{ withNote: true/false }
return different data
