Lightstreamer 在 JS 中设置连接选项

Question

您好，我尝试理解这个库，我在第 187 行有一个 python 源代码https://github.com/ig-python/ig-markets-api-python-library/blob/master/trading_ig/lightstreamer.py我能够添加 LS_op2 或设置 LS_container 但我在 js 版本上执行此操作时遇到问题。

我想要的第一条信息是：

LS_op2=create&LS_phase=5701&LS_cause=new.api&LS_polling=true&LS_polling_millis=0&LS_idle_millis=0&LS_cid=pcYgxn8m8 feOojy*****f3g2.pz479mDv&LS_adapter_set=DEMO&LS_container=lsc&

但我只得到

LS_phase=3201&LS_cause=new.nullresp&LS_polling=true&LS_polling_millis=0&LS_idle_millis=0&LS_cid=pcYgxn*** feOojyA1U661i3g2.pz47Af6k&LS_adapter_set=DEMO&

也许有人有想法，这是我的来源，谢谢。

            sub.setDataAdapter("QUOTE_ADAPTER");
            sub.setRequestedSnapshot("yes");

            sub.addListener({
                onItemUpdate: function(obj) {
                   console.log(obj.getValue("stock_name") + ": " + obj.getValue("last_price"));

            });
            client.subscribe(sub);

If the question is why Lightstreamer javascript SDK 8.0.3 library creates a different request, it is because the python code provided as reference (which doesn't lean on any SDK library) uses an earlier version of the communication protocol. 无论如何，javascript 库发出的请求应该可以工作。
