我正在使用 JSON 提取器来获取 technicalSettings 的值。这些值分配给变量 pPublishTechSettings。

现在我想访问变量 ${pPublishTechSettings_ALL} 中的每个数据。这个 JSON.

有两个值

我使用 ${pPublishTechSettings_0}、${pPublishTechSettings_1} 等变量来访问数据。但是它只适用于 ${pPublishTechSettings_1} 并且它给了我两个 technicalSettings 数据。

如何在 BeanShell Sampler 中访问单个 technicalSettings 数据，如 ${pPublishTechSettings_0}、${pPublishTechSettings_1}...？

注：-

当我在在线工具 JSON 中使用此 http://www.jsonquerytool.com/ and querying it like $..data..technicalSettings[0], $..data..technicalSettings1 时，我得到了正确的值。

Answer 1

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：

Answer 2

请注意 since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language 用于编写脚本，因此我会给您 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())
}
