如何追踪盗用SoundCloud ClientID发起的自动播放请求来源？

Hey Aung Pyae, sorry to hear your free Burmese music app is hitting SoundCloud's rate limits unexpectedly—ClientID theft is such a frustrating issue for indie devs who are just trying to help their community. Let's walk through actionable steps to trace those rogue requests and lock things down:

1. Check SoundCloud's Developer Dashboard for Request Details #

Your first stop should be SoundCloud's developer portal. Log in, find your app's dashboard, and look for sections like Request Analytics or Error Logs. Here you'll find key data to spot anomalies:

• IP Addresses: Compare these to your app's internal usage stats (if you track user IPs). Any IPs spamming requests way above average are likely bots.
• User-Agent Strings: Your app sends a unique UA string (like MyBurmeseMusicApp/1.0 (Android; 13)). Requests with generic UAs (like curl/7.68.0 or a random bot name) are dead giveaways of stolen ClientID usage.
• Request Timestamps: Bots often send requests in rigid, high-frequency patterns (e.g., one every 2 seconds nonstop) which will stick out next to your legitimate users' more sporadic listening habits.

2. Add Custom Tracking Parameters to Your App's Requests #

Modify your app to attach unique, app-specific query parameters to every /tracks/:id/stream request. For example:

/tracks/12345/stream?app_tag=my_burmese_music_app&device_hash=abc123xyz (generated per device)

• app_tag is a hardcoded string only your app uses (keep it simple, not your ClientID)
• device_hash is a non-identifiable, random hash generated when the app is first installed (no need to collect personal data here—just something unique per user device)
  These parameters will show up in SoundCloud's request logs, so you can filter out any requests that don't carry your tags. Those untagged requests are the ones using your stolen ClientID.

3. Proxy All Requests Through Your Own Backend (The Ultimate Fix) #

The root problem here is probably that your ClientID is exposed in your app's frontend code (easy for scrapers to find). Fix this by setting up a simple backend server to act as a middleman:

• Your app sends a request to your server with the track ID it wants to play
• Your server forwards the request to SoundCloud using your ClientID (never exposed to users)
• Your server sends the stream URL back to the app
  Even if you're not a backend pro, this is super doable with tools like Express.js (Node.js) or Flask (Python)—there are tons of free, simple tutorials for request forwarding.

Best of all, you'll be able to log every single request to your server: IP addresses, User-Agents, request counts, etc. You can even add your own rate limiting here to block abusive IPs before they hit SoundCloud.

4. Audit for Accidental ClientID Leaks #

Double-check if your ClientID was exposed somewhere by mistake:

• Did you push frontend code with the ClientID to a public GitHub repo? Use GitHub's built-in secret scanning to check for exposed API keys.
• Is the ClientID visible in your app's APK/IPA file? Use a basic decompiler to verify (for native apps)
• Did you share the ClientID in forums, Discord servers, or other public spaces while troubleshooting?

5. Rotate Your ClientID If Needed #

If you confirm the ClientID is stolen and can't block the rogue traffic right away, head back to SoundCloud's developer dashboard, generate a new ClientID, and disable the old one. Update your app (and backend, if you set one up) with the new ID—this will immediately stop the stolen ID from working.
