golang micro client 报错500 {"id":"go.micro.client","code":408,"detail":"call timeout: context deadlin

go micro web端链接services时，第一次访问提示500(broken pipe),排查发现客户端请求services时返回

 {"id":"go.micro.client","code":408,"detail":"call timeout: context deadline exceeded","status":"Request Timeout"}

修改micro client超时时间后没再出现过这种状况，待跟踪

具体修改：

#service增长CallOption并设置超时时间
var opss client.CallOption = func(o *client.CallOptions) {
    o.RequestTimeout = time.Second * 30
    o.DialTimeout = time.Second * 30
}

func (VipService) GetTotalCash() (*vip.CashResponse, error) {
    return VipSrv.GetTotalCash(context.TODO(), &vip.CashRequest{}, opss)
}
