xg3396 发表于 2010-5-26 15:25:41

用LoadRunner url协议录制用c#+ajax+json+iis6开发的web程序，只录制登陆，回放时候不能登录，并提示“数据类型转化失败..”江湖救济主要在404.ASHX 和137.ASHX处报错

在线等待，自己顶一下

sc_zk2008 发表于 2010-5-26 16:33:34

你把回放日志的错误信息贴出来

xg3396 发表于 2010-5-26 16:39:21

回放日志里面没错误，我是在 lr viewer中看到的，具体错误见附件图片

xg3396 发表于 2010-5-26 16:41:09

回放时没错误但是就是登录不成功
从viewer中看到

回放时没错，vieweR应该显示的是本身系统程序报的错吧，建议先分析下系统程序吧，看看执行到此处，后台报的是什么

xg3396 发表于 2010-5-26 16:55:31

后台也是报数据类型转化失败

云层发表于 2010-5-26 17:26:30

我觉得这是服务器上开发的代码写的不好导致的，你传递过去一个非法值，然后服务器就出错了，说明代码没有做任何错误处理直接引用了，所以这个问题是功能的bug和你没啥关系，你就测试了一个不太正常的数据包而已

谢谢

辛苦辛苦！！

同意，还是试试让研发的看看程序吧

xg3396 发表于 2010-5-27 22:46:14

已经解决了，谢谢解答－－－－lr抓取的包少了东西，用函数加上就成了

xiajianrong 发表于 2010-6-9 10:27:46

程序有没有做登陆的限制？
比如已经登陆不会再让登陆。

其次你可以其他账户再录制个脚本，看看两个脚本间有什么区别。
