Gatling：從JSON中獲取特定值的條件

我是加特林的新手，在這方面有點掙扎。

我有一個來自 HTML 的 JSON 物件：

<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，呈現這個：

{
  "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
    }
  ]
}

為了從那個 div 中獲取這個 JSON 陣列并將它保存到 Gatling 的會話變數中，我寫了這個“檢查”：

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

然后在執行腳本后在控制臺中列印結果，我寫了這個：

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

這將在控制臺中列印出您在上面看到的完整的美化 JSON 陣列。

現在在 JSON Array 中，我們可以看到當“isInProgress”為 false時有幾個 id 。

那么我的問題是，當“isInProgress”為假時，如何獲取住宿的第一個 id ？

所以：如果“IsInProgress”為假 => 獲取該陣列中的第一個住宿 ID。

以下代碼使用 Javascript，但應該很容易轉換為 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]);

根據我之前的回答，您需要check一個帶有條件的 json-path：

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

解釋：

@.isInProgress==false- 它是 array 中每個物件的條件accommodations。可以在此處找到有關 json-path 的更多詳細資訊

Gatling 的方法find回傳第一次出現。也存在findAll回傳所有值的方法......
