我正在使用 JSON 提取器来获取技术设置的值。这些值被分配给变量 pPublishTechSettings。

现在我想访问变量 ${pPublishTechSettings_ALL} 中的每个数据。此 JSON 中有两个值。

我使用 ${pPublishTechSettings_0}、${pPublishTechSettings_1} 之类的变量来访问数据。但它仅适用于 ${pPublishTechSettings_1}，它为我提供了两个 TechnicalSettings 数据。

如何在 BeanShell 采样器中访问单个技术设置数据，例如 ${pPublishTechSettings_0}、${pPublishTechSettings_1}...？

注意：-

当我在在线工具http://www.jsonquerytool.com/ 中使用此 JSON 并像 $..data..technicalSettings[0]、$..data..technicalSettings1 一样查询它时，我得到了正确的值。

【解决方案1】：

请注意 since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language 用于编写脚本，因此我将为您提供 Groovy 选项，类似于：

def technicalSettings = new groovy.json.JsonSlurper().parseText(vars.get('pPublishTechSettings_ALL'))

technicalSettings.eachWithIndex { setting, index ->
    log.info('Setting ' + index + ': ' + new groovy.json.JsonBuilder(setting).toString())
}

【解决方案2】：

使用ForEach Controller。

使用路径表达式为：.data.technicalSettings[*]

您的 JSON 路径提取器设置如下：

每个控制器的设置如下：

为每个控制器添加请求并在请求中使用${myvar}。你会得到这样的东西：
