通过实现webSocket.WebSocketRequestOptions接口封装了一个Option对象，通过该对象封装了Map类型的header，但是header没有带上去？

Question

websocket建连的时候，header传的Map<string,string\>，发现header没带上去，header是封装在一个对象实例里的。

相关代码：

class WebSocketRequestOptionsImpl implements webSocket.WebSocketRequestOptions {
    header?: Object;
    constructor(options: webSocket.WebSocketRequestOptions) {
        this.header = options.header;
    }
}

连接建立时使用demo可参考如下：

import webSocket from '@ohos.net.webSocket';
import { BusinessError } from '@ohos.base';
let ws = webSocket.createWebSocket();
let header: HashMap<string, string> = new HashMap();
header.set("key", "value")
header.set("key2", "value2")
let url = "ws://"
ws.connect(url, header as webSocket.WebSocketRequestOptions, (err: BusinessError, value: Object) => {
    if (!err) {
    console.log("connect success");
    } else {
        console.log("connect fail, err:" + JSON.stringify(err))
    }
});
