世界杯好友预测游戏网站开发：创建游戏与参与者功能需求

Hey there! Building a World Cup prediction game for your friend group sounds like a total blast. Let's walk through how to implement those core features smoothly:

1. Unverified User Game Creation Flow #

First, you'll need a straightforward frontend form for unauthenticated users to launch their game:

• Build a form with two required fields: Game Name (text input, with validation to prevent empty submissions) and Email Address (email input, with frontend checks for valid format, plus backend validation as a safety net).
• On form submission, send the data to your backend endpoint (e.g., POST /api/create-game).

2. Auto-Generated Password & Email Delivery #

Once the backend receives the game creation request:

• Generate a secure random password (aim for 8-12 characters with a mix of letters, numbers, and symbols). Use a library like bcrypt to hash the password before storing it in your database—keep the plaintext version only temporarily to send via email.
• Save the game details (name, creator email, hashed password, game status) to your database.
• Set up an email service integration (use server-side SMTP libraries or transactional email tools) to send the plaintext password to the creator's email. Include clear steps on how to log in later using their email and this password.

3. Participant Registration Code Generation #

Alongside creating the game and password, generate a unique registration code:

• Use a UUID or a custom short alphanumeric string (6-8 characters, case-insensitive for ease of sharing) as the game's registration code.
• Link this code to the game in your database and mark it as active (you can add logic to disable it once the game starts if needed).
• Include this registration code in the confirmation email to the creator, so they can easily share it with their friends.

4. Friend Registration Flow #

For friends to join the game:

• Create a "Join Game" form that asks for the registration code, the participant's name, and optionally their email (if you want to send updates or reminders).
• On submission, the backend checks if the registration code exists and is active. If valid, create a participant entry linked to the game in your database. Optionally, send a confirmation email to the new participant to confirm they've joined successfully.

Quick Pro Tips #

• Add validation on both frontend and backend to catch invalid submissions (like empty fields or fake emails) early.
• Never store plaintext passwords in your database—only the hashed version to keep user data secure.
• Consider adding a "Resend Password" feature in case the creator misplaces their initial email.
