最近在测试google docs云业务，在录制了创建新文档的操作后，需要进行关联，每个文档都有一个ID，那么关联的话首先要将服务器生成的这个ID取出来，然后把下面用到此ID的所有链接都进行参数化，这样回放的时候才会真正成功的完成创建文档的操作。

开始在进行录制时，得到的创建文档的url的脚本

web_url("create", 
		"URL=https://docs.google.com/document/create?folder=0ALZWwXWNwhrNUk9PVA",

		LAST);

由脚步可以看出，服务器为此文档生成的ID为

1gVZW2KXuUK1uCui6S0-5Q9r-pDRHmca3aoU7IIRLhN0

那么我们就要把此ID进行参数化，首先在creat的url上写上

web_reg_save_param("responseText",
        "LB=d/",
        "RB=/edit",
        "Search=All",
        LAST);

注意左右边界。然后将下面所有出现的ID进行参数化。

但是，问题出现了。。。

回放的时候发现，服务器没有返回新的ID，即服务器端并没有真正创建新文档。

此时分析上面脚步发现，create的url里包含很多url请求，而在第一个请求后服务器生成了一个ID，但在下面的请求中就直接用到了此ID，而这些请求都包含在一个url中（即create的url），因此想到的方法就是首先把第一个请求和下面的请求分开，在第一个请求后用web_reg_save_param去获得ID，然后在后面要用的ID的请求中参数化。

因此改变了录制模式

Recording Options->Recording,选择HTML-based script后，点击advanced，Script type中选择第二个，下面的选项也选择第二个，即Record in separate steps and use concurrent groups.

接着再次录制，产生脚本

web_url("create", 
		"URL=https://docs.google.com/document/create?folder=0ALZWwXWNwhrNUk9PVA", 
		"TargetFrame=", 
		"Resource=0", 
		"RecContentType=text/html", 
		"Referer=", 
		"Snapshot=t38.inf", 
		"Mode=HTML", 
		LAST);

回放时在Replay log中发现此create产生了四个请求，并且服务器端生成了新的ID。此时，在上面再加上上述web_reg_save_param函数，并将下面脚本中所有以前的ID进行参数化。再次回放，打开google docs，发现文档创建成功。

总结：出现错误时，借助日志和必要的函数如web_reg_save_param分析客户端和服务器的交互，服务器的响应等信息来分析错误原因，并不断的尝试，相信问题一定会解决。
