从 Loadrunner 中的多个下拉列表中捕获响应值

Question

我必须分别捕获 <select name="fromPort"> 和 <select name="toPort"> 中的选项值，以便使用 loadrunner 进行关联。

我把正则表达式写成

<select name="fromPort" class="form-inline">(.+?)</select>

从第一个开始捕获，但它显示没有匹配。

<form action="reserve.php" method="post">
        <select name="fromPort" class="form-inline">
            <option value="Paris">Paris</option>
            <option value="Philadelphia">Philadelphia</option>
            <option value="Boston">Boston</option>
            <option value="Portland">Portland</option>
            <option value="San Diego">San Diego</option>
            <option value="Mexico City">Mexico City</option>
            <option value="São Paolo">São Paolo</option>
        </select>
        <p>
        <h2>Choose your destination city:</h2>
        <select name="toPort" class="form-inline">
            <option value="Buenos Aires">Buenos Aires</option>
            <option value="Rome">Rome</option>
            <option value="London">London</option>
            <option value="Berlin">Berlin</option>
            <option value="New York">New York</option>
            <option value="Dublin">Dublin</option>
            <option value="Cairo">Cairo</option>
        </select>
        <p></p>
        <div class="container">
            <input type="submit" class="btn btn-primary" value="Find Flights"/>
        </div>
    </form>

当我尝试使用 notepad++ 时，当需要捕获多行响应时，有一个复选框可供选择。当我检查它时，相同的正则表达式正在工作。enter code here

Answer 1

考虑到您在房子的从/到侧涉及多个类似的标签，我的回答不太优雅。我将建议备份，使用 \"fromPort" class=\"form-inline\"\n" 或 \"toPort" class=\"form-inline\"\n" 的 LB 条件捕获到“\n”的结束标记

您将得到两个字符串变量，例如“Correlated_from”和“Correlated_to”，其中包含选项值。接下来是转换为数组结构。

可能有十几种方法可以将字符串分开，但我会推荐一个函数，它会在换行符处中断，跳转子字符串中的第一个“\t\t”字符，并保存它之间的值和下一个“

通过遵循标准的 LoadRunner 伪数组结构，可以使用标准的 LoadRunner 函数从伪数组中分配变量 - lr_paramarr_* 函数集。

Answer 2

你可以试试这个

好吧，我所做的是。

• 使用这个从选择匹配的选择标签中提取所有选项

  (?:<select name="(fromPort|toPort)" class="form-inline">\s+)([\w\W]+?)(?=\s+<\/select>)

• 比将每个选项作为单个元素拆分为一个数组。

• 比使用此正则表达式从每个选项中提取的值。

  (?<=\s*?<option value=")(.*?)(?=">.*?<\/option>)

let str =`<form action="reserve.php" method="post">
        <select name="fromPort" class="form-inline">
            <option value="Paris">Paris</option>
            <option value="Philadelphia">Philadelphia</option>
            <option value="Boston">Boston</option>
            <option value="Portland">Portland</option>
            <option value="San Diego">San Diego</option>
            <option value="Mexico City">Mexico City</option>
            <option value="São Paolo">São Paolo</option>
        </select>
        <p>
        <h2>Choose your destination city:</h2>
        <select name="toPort" class="form-inline">
            <option value="Buenos Aires">Buenos Aires</option>
            <option value="Rome">Rome</option>
            <option value="London">London</option>
            <option value="Berlin">Berlin</option>
            <option value="New York">New York</option>
            <option value="Dublin">Dublin</option>
            <option value="Cairo">Cairo</option>
        </select>
        <p></p>
        <div class="container">
            <input type="submit" class="btn btn-primary" value="Find Flights"/>
        </div>
    </form>`
    
let selectAllOption = str.match(/(?<=<select name="(fromPort|toPort)" class="form-inline">\s+)[\w\W]+?(?=\s+<\/select>)/g);

let splitedOptions = selectAllOption.map(e=>e.split('\n'))
let finalValues = splitedOptions.map(e=>{
  return e.map(ele=>{
    return ele.match(/(?<=\s*?<option value=")(.*?)(?=">.*?<\/option>)/g)
  })
})
console.log(finalValues);

Answer 3

我使用 LB="select id="xxxx"" 和 RB=""

提取选择

然后使用类似以下的内容来获取所有选项（如果我想随机提交哪个脚本，或者我选择已经选择的一个，如果我想提交默认选择是什么。每当我需要使用复杂的正则表达式 我通常将测试用例硬编码到一个临时的测试动作中，以便在实际应用之前测试出逻辑。
