    // 如果是POST/PUT请求,并且内容类型为JSON,则读取内容体

        if err == nil {
            defer ctx.Request().Body.Close()

    //下面是返回日志
    fields["res_status"] = ctx.ResponseWriter().StatusCode()
    if ctx.Values().GetString("out_err") != "" {
        fields["out_err"] = ctx.Values().GetString("out_err")

    }
    fields["uid"] = ctx.Values().GetString("uid")
    timeConsuming := time.Since(start).Nanoseconds() / 1e6
    logger.WithFields(fields).Infof("[http] %s-%s-%s-%d(%dms)",
        p, ctx.Request().Method, util.GetCilentIp(ctx.Request()), ctx.ResponseWriter().StatusCode(), timeConsuming)
}

整个请求数据都有了。方便调试
