LR回放socket时候，lrs_receive接收到的buffer字节数不稳定，与录制时不一致

qicyt1812 · 发表于 2008-3-27 15:28:09

这几天在学习使用LR录制socket脚本，不断的遇到问题，寻找了很多的解决办法，但是都是会出现问题。我录制的gtalk的发送和接收消息，回放时遇到这样两个问题：
1、接收消息的时候不是很正常，有时候是0bytes，有时候又会有bytes，但是总算和录制的时候不匹配，不晓得啥原因。
2、同事能够接收到我用lr发送过去的消息，为什么我却不能接收到同事回复的消息呢？一开始以为我没有开聊天窗口的原因，聊天窗口开启了也没有任何反映，请各位帮忙想想看是啥子原因？

下面附上我的脚本、data.ws、回放信息

Action.c(26)和Action.c(36)行接收buffer不规律，有时候能接收到有时候就接收不到，即使接收到了也与录制时候不匹配，我想可能与时间有关吧。

请各位高手帮帮忙，帮偶看看到底是啥原因，俺该如何解决这个问题，这个mismatch着实让人头疼呢

Zee · 发表于 2008-3-27 18:43:00

打开扩展日志查看数据有什么不同。

别人给你回消息，应该不是你模拟出来的。

你可以设置一个循环一直等。然后让那边主动发消息过来。
试试。

liangjz · 发表于 2008-3-27 20:15:30

loadrunner 录制下来的是当时的(旧)的数据通信过程

如果回放是有一些数据包变化或者随时间戳变化，服务器响应的字节就不一定相同了，导致buffer mismatch。

对于socket协议，需要测试工程师非常清楚协议报格式

请问我该如何设置循环呢？是不是在lrs_receive的前后加上循环语句，那边主动发消息过来，是不是指让对方收到我的信息后，通过gtalk窗口给我回复消息啊，这样就可以收到了吗？

我使用扩展日志后发现，如果buf48接收到消息了，buf49就接收不到了，buf48接收不到消息的时候，buf49就能接收到

从扩展日志中能够接收到对方发过来的buffer，为什么我的客户端却看不到呢？
