Lightstreamer 在 JS 中設置連接選項
[英]Lightstreamer set connection options in JS
問題描述
您好，我嘗試理解這個庫，我在第 187 行有一個 python 源代碼https://github.com/ig-python/ig-markets-api-python-library/blob/master/trading_ig/lightstreamer.py我能夠添加 LS_op2 或設置 LS_container 但我在 js 版本上執行此操作時遇到問題。
我想要的第一條信息是：
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&
也許有人有想法，這是我的來源，謝謝。

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. 無論如何，javascript 庫發出的請求應該可以工作。
如何在vis js中設置選項？
