json - 我是否需要在 Jmeter 项目中导入任何 Jar 文件才能使用“import groovy.json.*”？？我该怎么做？

Question

我正在尝试通过以下代码验证我的 API 的 JSON，但它失败了。可能是什么原因 ？

import groovy.json.*

JSONObject obj1 = '''{"success":true,"error":null,"data":{"Months":[{"Id":0,"MDN":"January 2020","H":[{"MI":100,"MN":"API Automation Testing Lower the better Metric-Sum","GL":"B","DS":"%","RT":"s"},{"MI":101,"MN":"API Automation Testing Higher the better Metric-Sum","GL":"A","DS":"%","RT":"s"},{"MI":102,"MN":"API Automation Testing Higher the better Metric-AVG","GL":"A","DS":"s","RT":"a"},{"MI":103,"MN":"API Automation Testing Lower the better Metric-Number-AVG","GL":"B","DS":"s","RT":"a"}],"T":[{"MI":100,"VL":"20.00","NA":false,"PTG":0.0,"S":null},{"MI":101,"VL":"0.20","NA":false,"PTG":0.0,"S":null},{"MI":102,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":103,"VL":"0.20","NA":false,"PTG":0.0,"S":null}],"MR":[{"MI":100,"VL":"1,536.00","NA":false,"PTG":1.0,"S":"danger"},{"MI":101,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":102,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":103,"VL":"0.00","NA":true,"PTG":0.0,"S":null}],"WR":[{"WN":1,"DT":[{"MI":100,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":101,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":102,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":103,"VL":"0.00","NA":true,"PTG":0.0,"S":null}],"SD":"29/12/2019","ED":"04/01/2020"},{"WN":2,"DT":[{"MI":100,"VL":"1,536.00","NA":false,"PTG":1.0,"S":"danger"},{"MI":101,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":102,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":103,"VL":"0.00","NA":true,"PTG":0.0,"S":null}],"SD":"05/01/2020","ED":"11/01/2020"},{"WN":3,"DT":[{"MI":100,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":101,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":102,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":103,"VL":"0.00","NA":true,"PTG":0.0,"S":null}],"SD":"12/01/2020","ED":"18/01/2020"},{"WN":4,"DT":[{"MI":100,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":101,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":102,"VL":"0.00","NA":true,"PTG":0.0,"S":null},{"MI":103,"VL":"0.00","NA":true,"PTG":0.0,"S":null}],"SD":"19/01/2020","ED":"25/01/2020"}],"SD":"01/01/2020","ED":"31/01/2020"}],"MND":"2019-12-29T00:00:00Z","MXD":"2020-01-25T00:00:00Z"}}'''

查看ObjectMapper似乎您正在尝试使用Jackson，这意味着您需要在JMeter Classpath中具有最小依赖项集（jackson-core和jackson-annotations）的jackson-databind

您也不需要这些JSONObjectand JsonNode，您的代码可以修改为：

def obj1 = '''your json here'''
def obj2 = prev.getResponseDataAsString()

def mapper = new com.fasterxml.jackson.databind.ObjectMapper()

def expected = mapper.readTree(obj2)
def actual = mapper.readTree(obj2)

if (!expected.equals(actual)) {
    AssertionResult.setFailure(true)
}
