Gatling ：从 JSON 中获取特定值的条件

Question

我是 Gatling 新手，在这方面有点挣扎。

我有这个来自 HTML 的 JSON 对象：

<div id="DATA--DECL-DATA">{"isCompany":false,"accommodations":[{"id":"00000000031000000067","isChecked":false,"name":"5 JULI 2017","addressLine1":"STRAAT 10 ","addressLine2":"1000 New York","nightsDeclared":0,"schoolNightsDeclared":0,"schoolNightsAttached":0,"taxableNights":0.0,"totalPayment":0.0,"isInProgress":false,"isLate":false,"isPayed":"false","deadline":"2021-12-31","initialAmount":0.0,"remainingAmount":0.0},{"id":"00000000031000006362","isChecked":false,"name":"BELLEVIE","addressLine1":"STRAAT 10 ","addressLine2":"1000 New York","isInProgress":false},{"id":"00000000031000006380","isChecked":false,"name":"BELLEVIE","addressLine1":"STRAAT 10 ","addressLine2":"1000 New York","isInProgress":true},{"id":"00000000031000006390","isChecked":false,"name":"BELLEVIE","addressLine1":"STRAAT 10 ","addressLine2":"1000 New York","isInProgress":true}]}</div>

如果美化了，渲染这个：

{
  "isCompany": false,
  "accommodations": [
    {
      "id": "00000000031000000067",
      "isChecked": false,
      "name": "5 JULI 2017",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": false
    },
    {
      "id": "00000000031000006362",
      "isChecked": false,
      "name": "BELLEVIE",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York"
      "isInProgress": false
    },
    {
      "id": "00000000031000006380",
      "isChecked": false,
      "name": "BELLEVIE",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": true
    },
    {
      "id": "00000000031000006390",
      "isChecked": false,
      "name": "BELLEVIE",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": true
    }
  ]
}

为了从那个 div 中获取这个 JSON 数组并将其保存到 Gatling 中的会话变量中，我写了这个“检查”：

.check(css("div#DATA--DECL-DATA").saveAs("myJsonObj"))

然后在脚本执行后在控制台中打印结果，我写了这个：

.exec { session => println("json = " + session("myJsonObj").as[String]); session }.exitHereIfFailed

这将在控制台中打印出您在上面看到的完整的美化 JSON 数组。

现在，在那个住宿 JSON 数组中，我们可以看到当 "isInProgress" 为 false 时有多个 id。

那么我的问题是，当 "isInProgress" 为假时，如何获取住宿的第一个 id？

所以：如果 "IsInProgress" 为 false => 获取该数组中的第一个住宿 id。

Answer 1

以下代码是用 Javascript 编写的，但应该很容易转换为 scala。

var json = {
  "isCompany": false,
  "accommodations": [
    {
      "id": "00000000031000000067",
      "isChecked": false,
      "name": "5 JULI 2017",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": false
    },
    {
      "id": "00000000031000006362",
      "isChecked": false,
      "name": "BELLEVIE",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": false
    },
    {
      "id": "00000000031000006380",
      "isChecked": false,
      "name": "BELLEVIE",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": true
    },
    {
      "id": "00000000031000006390",
      "isChecked": false,
      "name": "BELLEVIE",
      "addressLine1": "STRAAT 10 ",
      "addressLine2": "1000 New York",
      "isInProgress": true
    }
  ]
}

var FilteredJson = json.accommodations.filter((value) => {if (value.isInProgress === false) {return value}});

//just take the first value of FilteredJson

console.log(FilteredJson[0]);

根据我之前的answer，您需要check 带有条件的json-path：

.check(jsonPath("$.accommodations[?(@.isInProgress==false)].id").find.saveAs("id"))

解释：

@.isInProgress==false - 这是数组accommodations 中每个对象的条件。 更多关于 json-path 的细节可以查看here

Gatling 的方法find 返回第一个匹配项。还存在返回所有值的方法findAll...
