新版本服务器WebSocket未推送新流问题及Javascript SDK版本咨询

Hey there, let's work through this problem you're facing with your updated streaming server. First, let's recap the core issue to make sure I'm on the same page: after upgrading to the latest server version, new users joining a room get the stream list via the streams array in the joinedTheRoom WebSocket message, but when a new user publishes a stream, existing room members don't receive the streamJoined notification. The server GUI shows streams are published correctly, but your logs only capture joinedTheRoom, initialized, and ping messages—plus the 2.1.0 version worked flawlessly before, and the new version's changelog is empty.

Here's a breakdown of steps to diagnose and fix this:

1. Audit Server-Side Event Trigger & Push Logic #

• Since your 2.1.0 server worked, the latest version likely has a breaking change in how stream publish events are handled. Check if the server's internal event (like streamPublished) is still correctly mapped to pushing the streamJoined message to all room members. It's possible the event name was renamed, or the conditional logic for sending the message was altered in the update.
• Enable debug-level logging on the server if you haven't already. Default logs might not capture the internal event flow, but debug logs will show if the server actually detects a new stream being published, and whether it enters the code branch responsible for sending streamJoined to existing users.

2. Verify Client-Side Stream Publish Request Compatibility #

• Even if your old client code worked with 2.1.0, the new server might expect a modified WebSocket message format for stream publishing. For example, it might now require additional parameters (like an explicit roomId field) or a changed method name that your current JS SDK isn't sending.
• Use your browser's Network tab (or a WebSocket debugging tool) to capture the publish request frame from the new user. Compare this to how publish requests looked in the 2.1.0 server setup. If there's a mismatch in payload structure or required fields, that could explain why the server creates the stream but doesn't trigger the streamJoined push.

3. JavaScript SDK Update Guidance #

• Yes, you almost certainly need to update your JS SDK to match the new server version. Streaming servers and their SDKs rely on tight protocol alignment—message schemas, event names, and request/response patterns often change between versions. Using a 2.1.0-era SDK with a newer server is a common cause of missing events like streamJoined.
• To get the updated SDK:
  • If this is an open-source project, check the project's official code repository for release packages matching your server version.
  • For commercial streaming platforms, log into your developer dashboard or official documentation portal to download the SDK tied to your server's release. Always ensure SDK and server versions are an exact match—cross-version mixing will cause compatibility gaps.

4. Temporary Workaround (If You Need Immediate Fixes) #

• If you can't resolve the server/SDK mismatch quickly, roll back to the 2.1.0 server version to restore normal functionality while you troubleshoot the new version.
• As a stopgap, implement a client-side polling loop: existing room members can periodically fetch the full room stream list from the server, compare it to their local stream inventory, and manually trigger streamJoined handling when new streams are detected. This isn't ideal long-term, but it can keep your service running while you address the root issue.

If none of these steps resolve the problem, gather your server debug logs, captured WebSocket publish frames, and the exact server version number, then reach out to the server's official support team—they'll have deeper insight into unrecorded changes in the empty changelog.
