### Method

# Soup Server add_websocket_handler

#### Declaration [src]

    void
    soup_server_add_websocket_handler (
      SoupServer* server,
      const char* path,
      const char* origin,
      char** protocols,
      SoupServerWebsocketCallback callback,
      gpointer user_data,
      GDestroyNotify destroy
    )

#### Description [src]

Adds a WebSocket handler to `server` for requests prefixed by `path`.

If `path` is `NULL` or “/”, then this will be the default handler for all requests that don’t have a more specific handler.

When a path has a WebSocket handler registered, `server` will check incoming requests for WebSocket handshakes after all other handlers have run (unless some earlier handler has already set a status code on the message), and update the request’s status, response headers, and response body accordingly.

If `origin` is non-`NULL`, then only requests containing a matching “Origin” header will be accepted. If `protocols` is non-`NULL`, then only requests containing a compatible “Sec-WebSocket-Protocols” header will be accepted. More complicated requirements can be handled by adding a normal handler to `path`, and having it perform whatever checks are needed and setting a failure status code if the handshake should be rejected.
