Sails.js 0.12.14生产环境会话超时异常求助（测试环境正常）

I get how urgent this is—you’re days away from launch, and the session timeout that’s fixed in staging is still plaguing production. Let’s break down the most likely culprits and fixes tailored to Sails.js 0.12.14:

1. Check Production Environment Configuration Overrides #

Sails.js prioritizes environment-specific config files over root-level ones when NODE_ENV=production. Double-check if there’s a config/env/production.js file with its own session settings. If it defines maxAge (even implicitly, maybe copied from staging earlier), it’ll overwrite the value in your root config/session.js.

Open config/env/production.js and either remove any conflicting session.maxAge entry, or update it to match your desired 24-hour window.

2. Verify Session Store Adapter Compatibility #

Session behavior can break if your production store adapter (like Redis, MongoDB, or even the default memory store) isn’t respecting the maxAge setting:

• Memory Store: Never use this in production—it’s not persistent and has known issues with timeout consistency. Switch to Redis/Mongo if you haven’t already.
• Redis: Ensure your Redis client adapter (e.g., connect-redis) is compatible with Sails 0.12.x. Some older versions ignore the maxAge parameter and rely on Redis server-level TTL settings. Check if your Redis instance has a default TTL that’s overriding your app’s config.
• MongoDB: If using connect-mongo, confirm the version matches Sails 0.12’s requirements. Older versions might not propagate the maxAge value to MongoDB’s document expiration.

3. Rule Out Reverse Proxy/Load Balancer Timeouts #

Production setups almost always use proxies like Nginx or load balancers, and these often have their own timeout settings that override your app’s config:

• Nginx: Check proxy_read_timeout and proxy_connect_timeout in your server block. If they’re set to 5-6 minutes, the proxy will terminate requests before your session expires, making it look like a session timeout. Set these values to at least 24 hours (or higher) to match your session config.
• Load Balancers: Cloud providers (AWS ALB, GCP LB) or on-prem balancers often have “idle timeout” settings. Make sure this value is longer than your session maxAge.

4. Audit Custom Middleware for Cookie Overwrites #

You added a custom middleware after session—double-check if it’s accidentally modifying the session cookie’s expiration. Use your browser’s DevTools to inspect the Set-Cookie header in production responses:

• Look for the session cookie’s Max-Age or Expires value. If it’s still set to 5-6 minutes, something is overwriting your config.
• Ensure your middleware isn’t calling req.session.cookie.maxAge or manually setting cookie headers that override the default session cookie.

5. Explicitly Set Cookie-Level maxAge #

Sails.js 0.12.x has a known quirk where the root session.maxAge might not propagate to the cookie settings correctly. Try explicitly defining it in the cookie object within your session config:

// config/session.js
module.exports.session = {
  secret: 'your-production-secret-key',
  maxAge: 24 * 60 * 60 * 1000,
  cookie: {
    maxAge: 24 * 60 * 60 * 1000, // Duplicate here to force cookie expiration
    secure: process.env.NODE_ENV === 'production' // Critical for production cookies
  },
  // ... your store adapter config
};

This ensures the cookie itself carries the correct expiration time, bypassing any potential config propagation issues in Sails.

Quick Debugging Tip #

Add a quick debug endpoint in production (temporarily!) to check the actual session config being used:

// api/controllers/DebugController.js
module.exports = {
  checkSession: function(req, res) {
    res.json({
      sessionMaxAge: req.session.cookie.maxAge,
      cookieExpires: req.session.cookie.expires
    });
  }
};

Hit this endpoint after logging in—if the sessionMaxAge isn’t 86400000 (24h in ms), you’ll know the config isn’t being loaded correctly.
