标题: 请教几个录制脚本的问题
初学loadrunner，感觉很迷茫，希望高手能指点一二

1.loadrunner的录制脚本的原理机制到底是怎么样的？

  看到网上有说是通过获取数据包解析成函数，那么在日志里是否可以看到获取数据包的日志，录制脚本的正确性是否应该根据获取的数据包来判断，如何判断呢，能否举个例子

2.该如何选择协议，我测试的系统是Spring+dwr的，选择协议web（http/html），html_base_script，录的过程有一个步骤计算量十分大，计算结果是ajax获取的。时间很慢，为什么录出来的脚本回放十分快，录的脚本基本上是
web_custom_request("LoginBO.login.dwr",
  "URL=http://localhost:9080/TEST/dwr/call/plaincall/LoginBO.login.dwr",
  "Method=POST",
  "Resource=0",
  "RecContentType=text/javascript",
  "Referer=http://localhost:9080/TEST/",
  "Snapshot=t382.inf",
  "Mode=HTML",
  "EncType=text/plain",
  "Body=callCount=1\n"
  "page=/TEST/\n"
  "httpSessionId=0000iT8QNpvdMWSgkKo4Vp2YWjd:-1\n"
  "scriptSessionId=A882B97F4922E8FB333CBB67970B1991707\n"
  "c0-scriptName=LoginBO\n"
  "c0-methodName=login\n"
  "c0-id=0\n"
  "c0-e1=string:super\n"
  "c0-param0=Object_Object:{staff_name:reference:c0-e1}\n"
  "batchId=0\n",
  LAST);

web_custom_request("ModelConditionConfigBO.try_count.dwr",
  "URL=http://localhost:9080/TEST/dwr/call/plaincall/ModelConditionConfigBO.try_count.dwr",
  "Method=POST",

是不是因为AJAX的原因所以录出来的脚本是这样的，脚本是正确的吗？这个函数是不是没有录到具体的过程？感觉很不理解，望高人指点

3.脚本中关联到底需不需要，CTRL+F8找不出关联的地方，我登陆的时候sessionId都没有做关联，脚本回放也没有发生错误，这是为什么呢

非常迷茫。。望各位高手指点

只能回答第三个问题，自动关联在很多情况下是不能做到完全关联的，需要自己查找需要关联的地方。
脚本回放没发生错误是因为你没有加验证点，你可以单步调试，看看每步执行时的页面都是什么，会有发现的～
