Function parseAuthMessage

src/Server/WebTerminalRequestHandler.cpp:314–327

Parse an auth message like {"type":"auth","user":"...","password":"..."}. The "user" field is optional: when omitted or empty, the caller-provided default (typically the server's default user) is preserved. This mirrors the HTTP path in `authenticateUserByHTTP`, where an absent `user` query parameter falls back to the server's default user.

/// parameter falls back to the server's default user.
bool parseAuthMessage(const String & json, String & user, String & password)
{
    auto object = parseRootObject(json);
    if (!object)
        return false;
    if (getStringField(object, "type") != "auth")
        return false;

    auto parsed_user = getStringField(object, "user");
    if (!parsed_user.empty())
        user = parsed_user;
    password = getStringField(object, "password");
    return true;
}
