java - 如何在 Jmeter 中从 json 文件准备多行

Question

我是 Jmeter 的新手，我正在 json 文件中生成随机数据(例如 n 个请求)。

这些是 json 文件中的请求 {"firstName":"Colton","lastName":"Alvarez","password":"K42mC7UQ","email":"Robert2@test.COM","orgName":"Alist","locationName ":"史迪威大道","address1":"史迪威大道","address2":"11史迪威大道","city":"旧金山","state":"南达科他州","country":"美国","zipCode":"12901","orgEmail":"Gavin@test.COM"}

{"firstName":"Stella","lastName":"Barrera","password":"BUiVwvAw","email":"Alex3@test.COM","orgName":"快速咨询","locationName":"科夫巷","address1":"科夫巷","address2":"8科夫巷","city":"迈阿密","state":"北卡罗来纳州","country": "美国","zipCode":"26257","orgEmail":"Anthony@test.COM"}

{"firstName":"Violet","lastName":"Trujillo","password":"O5belqdN","email":"London1@test.COM","orgName":"Buapel Limited ","locationName":"福特街","address1":"福特街","address2":"21福特街","city":"迈阿密","state":"加利福尼亚州","country":"美国","zipCode":"72159","orgEmail":"Thomas@test.COM"}

{"firstName":"Aubrey","lastName":"Tyler","password":"Qj32XyDE","email":"Julian4@test.COM","orgName":"Yrsa Associates ","locationName":"夏日广场","address1":"夏日广场","address2":"9夏日​​广场","city":"纽约","state":"马里兰州","country": "美国","zipCode":"19250","orgEmail":"Cooper@test.COM"}

{"firstName":"Emily","lastName":"Gilliam","password":"TNKqqqfX","email":"London5@test.COM","orgName":"Alist","locationName":"华盛顿步行街","address1":"华盛顿步行街","address2":"19华盛顿步行街","city":"纽约","state":"马萨诸塞州","country":"美国","zipCode":"90694","orgEmail":"Tristan@test.COM"}

现在我希望 jmeter 将此数据作为请求正文来命中 n 个线程

问题是，当我将单个请求的数据放入 json 文件时，它会读取它并让我成功。但是当多行数据放入 json 中时，它会尝试在请求中获取整个数据。 但是我希望 jmeter 对于每个不一样的请求从 json 中一一挑选数据。

很可能是因为__FileToString() function将整个文件读取到请求正文中，如果文件中的新行上有单独的 JSON 正文负载，您可能需要使用 __StringFromFile() function相反，每次调用时都会从给定文件中读取下一行。

此外，如果数据确实是“随机”的，您甚至可以继续使用单个测试数据“占位符”，例如将其更改为如下所示:

{
  "firstName": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(6),)}",
  "lastName": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(10),)}",
  "password": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphanumeric(8),)}",
  "email": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(6),)}@test.COM",
  "orgName": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(6),)}",
  "locationName": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(20),)}",
  "address1": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(20),)}",
  "address2": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(20),)}",
  "city": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(10),)}",
  "state": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(10),)}",
  "country": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(8),)}",
  "zipCode": "${__groovy(orgorg.apache.commons.lang3.RandomStringUtils.randomNumeric(5),)}",
  "orgEmail": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(6),)}@test.COM"
}

和wrap your __FileToString() function into __eval() function像:

${__eval(${__FileToString(test.json,,)})}

这样您就可以在每个请求上获得随机值
