版本过于陈旧，是否有更新的打算呢？

比如这种代码，这个方法怎么用呢

[astronauts1]

如下是否更合理呢？

func (c *Client) DescribeListenersWithContext(ctx context.Context, request *DescribeListenersRequest) (*DescribeListenersResponse,err) {
    if request == nil {
        request = NewDescribeListenersRequest()
    }
    request.SetContext(ctx)
    request.SetContentType("application/x-www-form-urlencoded")

    response := NewDescribeListenersResponse()
    err, _ := c.Send(request, response)
    if err != nil {
        return nil,err
    }
    return response,nil
}
