scala - 在 Scala/Gatling 中提取 json 响应的第 n 个元素

问题描述

我在 json 中有一个响应正文，我想在其中提取值：ID_ADFA0741-6A46-4A90-8AAE-BC7DB18B27E1

在下面的 json 结构中。

.check(jsonPath("$..key").saveAs("key")))

给我价值 M01A

我如何使用检查来获取元素编号 2 的值“key”（下面的“key”的第二次出现？

解决方案

好的，有两种方法。

第一个 - 您可以“直接”定义需要提取的元素：

.check(jsonPath("$.[1].key").saveAs("key")))

第二种方式 - 您可以保存所有元素，然后通过 Gatling EL 使用所需的元素：

.check(jsonPath("$..key").findAll.saveAs("keys")))

"${keys(1)}"
