json: cannot unmarshal number into Go struct field xxx of type string

This is a common error and happens in many cases, for example:

m.wsService.SetCallBack(gatews.ChannelFutureBalance, func(msg *gatews.UpdateMsg) {
    var accounts []gatews.FuturesAccountBook

    if m.conf.Debug && msg.Event == "update" {
        log.Printf("ChannelFutureBalance: %s\n", string(msg.Result))
    }

    if msg.Error != nil {
        errorHandler(convertWsError(msg.Error, excommon.GlobalMarketTypeFutures, excommon.Unknown))
        return
    }

    if msg.Event != "update" {
        return
    }

    if err := json.Unmarshal(msg.Result, &accounts); err != nil {
        errorHandler(convertWsError(err, excommon.GlobalMarketTypeFutures, excommon.Unknown)) // ①
    }
        // ...

① will show the error: json: cannot unmarshal number into Go struct field FuturesAccountBook.balance of type string. This kind of bug also occurs in the case of GateWsFuturesTrade and GateWsFuturesOrder et al.

It could be a solution to refactor the structs in customized code, but it will be much better if your guys can fix this problem inside this package.

It seems there are type mismatch. We'll look into this issue

Thanks

Btw, the FuturesPosition struct should also be added. ❤️
