我是否需要在 Jmeter 項目中導入任何 Jar 文件才能使用“import groovy.json.*”？？ 我該怎么做？

Question

我試圖通過以下代碼驗證我的 API 的 JSON，但它失敗了。 可能是什么原因 ？

import groovy.json.*

6 錯誤

Answer 1

JSONObject不是一個 groovy 對象——它可能來自某個庫（比如簡單的 json），如果你想使用這個類應該很重要。

但是，提供的常規代碼是錯誤的： obj1是一個 GString，因此這里不可能進行轉換。 因此，您真的應該閱讀有關您選擇的 json 處理庫的教程，以獲得正確的語法。

總而言之，作為一般說明，如果您已經在使用 Groovy，請考慮使用內置JSONSlurper ：

import groovy.json.*

def obj1 =...
def slurper = new JsonSlurper()
def json1Obj = slurper.parseText(obj1)
...

Answer 2

查看ObjectMapper似乎您正在嘗試使用Jackson ，這意味着您需要jackson-databind與JMeter Classpath 中的最小依賴集（ jackson-core和jackson-annotations ）

您也不需要這些JSONObject和JsonNode ，您的代碼可以修改為：

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)
}
