来自 JSON 文件的 Jmeter trim 空格

Question

我有以下Json:

{
      "tipopersona": "M",
      "regimen": "36",
      "periodicidad": "Y",
      "ejercicio": "2020",
      "periodo": "035",
      "periodoDesc": "Del Ejercicio",
      "tipoDeclaracion": "001",
      "tipoDeclaracionDesc": "Normal",
      "tipoComplementaria": "",
      "tipoComplementariaDesc": "",
      "cmbISSIF": "1",
      "obligaciones": [ "0101", "0192" ],
      "preguntasPerfil": { "178": "1" },
      "rfc": "AAC920317CM8",
      "rechazopropuesta": false,
      "fechaVencimiento": "2021-03-31T00:00:00",
      "errores": true,
      "xmldeclaracion": ""
    }

我需要从 Json 中删除空格和换行符，就像 JSR223 或 Beanshell 中的以下示例：

{"tipopersona":"M","regimen":"36","periodicidad":"Y","ejercicio":"2020","periodo":"035","periodoDesc":"DelEjercicio","tipoDeclaracion":"001","tipoDeclaracionDesc":"Normal","tipoComplementaria":"","tipoComplementariaDesc":"","cmbISSIF":"1","obligaciones":["0101","0192"],"preguntasPerfil":{"178":"1"},"rfc":"AAC920317CM8","rechazopropuesta":false,"fechaVencimiento":"2021-03-31T00:00:00","errores":true,"xmldeclaracion":""}

我正在使用以下代码：

String data = vars.get("json");
data = data.replaceAll(" ", "");
data = data.replaceAll(System.getProperty("line.separator"),"");
vars.put("data", data);

但在 Debug Sampler 中它仍然显示空格：

Answer 1

最简单的方法是在 json 变量上使用 JSON 提取器作为 sampler.Your 代码的子级可能会替换 json 键和值中的所有空格.

Answer 2

Since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language 用于编写脚本
Groovy has built-in JSON support

假设以上几点，您可以使用以下单行代码实现您的目标：

vars.put('data', (new groovy.json.JsonBuilder(new groovy.json.JsonSlurper().parseText(vars.get('json'))).toString()))
