1）关联的定义

很多时候，当时录完之后，没有问题。过一段时间再跑脚本，就不会成功。比如session，过期了，再一次使用，就会出错。这个时候，需要在每次访问的时候动态的拿到session，这种情况就需要用到关联。

2）参数化和关联的区别的阐述

参数化变的是提交的东西。关联的值是从服务器响应中拿到

3）什么时候需要关联？

服务器返回的动态变化且对业务有影响的

关联小例子

演示WebTours登录时，如果总是用同一个session，可能登录不成功，需要对session关联。

Action()
{
    web_url("WebTours",
        "URL=http://127.0.0.1:1080/WebTours/",
        "TargetFrame=",
        "Resource=0",
        "RecContentType=text/html",
        "Referer=",
        "Snapshot=t8.inf",
        "Mode=HTML",
        EXTRARES,
        "URL=http://www.bing.com/favicon.ico", ENDITEM,
        LAST);

    web_submit_data("login.pl",
        "Action=http://127.0.0.1:1080/WebTours/login.pl",
        "Method=POST",
        "TargetFrame=body",
        "RecContentType=text/html",
        "Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
        "Snapshot=t9.inf",
        "Mode=HTML",
        ITEMDATA,
        "Name=userSession", "Value=121391.541595788zcttAHHptcAiDDDDDHtztptztfcf", ENDITEM,
        "Name=username", "Value=jojo", ENDITEM,
        "Name=password", "Value=bean", ENDITEM,
        "Name=JSFormSubmit", "Value=off", ENDITEM,
        "Name=login.x", "Value=54", ENDITEM,
        "Name=login.y", "Value=16", ENDITEM,
        LAST);

    web_url("SignOff Button",
        "URL=http://127.0.0.1:1080/WebTours/welcome.pl?signOff=1",
        "TargetFrame=body",
        "Resource=0",
        "RecContentType=text/html",
        "Referer=http://127.0.0.1:1080/WebTours/nav.pl?page=menu&in=home",
        "Snapshot=t10.inf",
        "Mode=HTML",
        LAST);
return 0;
}

找到usersession是从哪个页面返回的。

技术分享

右键value的值添加关联。

关联后代码变化：

Action()
{
    web_reg_save_param_ex(
        "ParamName=CorrelationParameter_1",
        "LB=userSession value=",
        "RB=>\n<table border",
        SEARCH_FILTERS,
        "Scope=All",
        "IgnoreRedirections=Yes",
        "RequestUrl=*/nav.pl*",
        LAST);

    web_url("WebTours",
        "URL=http://127.0.0.1:1080/WebTours/",
        "TargetFrame=",
        "Resource=0",
        "RecContentType=text/html",
        "Referer=",
        "Snapshot=t8.inf",
        "Mode=HTML",
        EXTRARES,
        "URL=http://www.bing.com/favicon.ico", ENDITEM,
        LAST);

    web_submit_data("login.pl",
        "Action=http://127.0.0.1:1080/WebTours/login.pl",
        "Method=POST",
        "TargetFrame=body",
        "RecContentType=text/html",
        "Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
        "Snapshot=t9.inf",
        "Mode=HTML",
        ITEMDATA,
        "Name=userSession", "Value={CorrelationParameter_1}", ENDITEM,
        "Name=username", "Value=jojo", ENDITEM,
        "Name=password", "Value=bean", ENDITEM,
        "Name=JSFormSubmit", "Value=off", ENDITEM,
        "Name=login.x", "Value=54", ENDITEM,
        "Name=login.y", "Value=16", ENDITEM,
        LAST);

    web_url("SignOff Button",
        "URL=http://127.0.0.1:1080/WebTours/welcome.pl?signOff=1",

return 0;
