LR自带例子WebTours回放时的参数关联问题

浏览数：43 / 时间：2015年06月09日

我用范例录了一个登录脚本，使用的是HTML-based，其它基本上都是默认设置。

使用自己注册的用户名/密码进入例子中后进行了一个最基本的登录操作然后退出，录制完毕后，然后回放，系统提示要求对userSession进行关联，手动关联好之后，回放，然后再设置runtime setting，将number of iteration改为5，再次回放时出现错误：

Action.c(61): Error -27987: Requested image not found [MsgId: MERR-27987]
Action.c(61): web_image("SignOff Button") highest severity level was "ERROR", 0 body bytes, 0 header bytes [MsgId: MMSG-26388]

刚开始一直怀疑是关联的问题，后来的解决方法如下：

1，打开recording options，在internet protocol下的recording中选择recording level为HTML-based script，点击HTML Advanced，选择script type为A script containing explicit.即可。
2，选择使用URL＿based script录制。

事例程序如下：

Action()
{

    web_set_max_html_param_len("100000");

    //添加关联
    web_reg_save_param("userSessionValue",
        "LB=userSession value=",
        "RB=>",
        "Ord=1",
        "Search=Body",
        LAST);

    //添加检查点
        web_reg_find("Search=Body",
        "SaveCount=sscount",
        "Text=Welcome",
        LAST);
