..我们想要一个正确的[格式化]（https://www.stackoverflow.com/help/how-to-ask）问题。 – Jer

当你说你想从响应中删除它们，你的意思是你创建了这个Json，并且只想发送非'null'值，或者你收到了这个值，并且想要清理Json？无论哪种情况，您使用的是哪种语言，以及您尝试了什么？尝试包括您的问题的[最小，完整，可验证示例]（http://stackoverflow.com/help/mcve）。 –

这个JSON响应是我们为一个请求获得的，我们需要将非空值传递给下一个请求。我们在Jmeter工具（beanshell）中使用它。请建议。 –

添加JSR223 PostProcessor作为返回该JSON响应

将下面的代码为 “脚本” 区域的请求的小孩：

def json = new groovy.json.JsonSlurper().parse(prev.getResponseData()) 

for (Iterator<Map.Entry> it = json.entrySet().iterator(); it.hasNext();) { 
    Map.Entry entry = it.next(); 
    if (entry.getValue() == null) { 
     it.remove() 
    } 
} 

vars.put("data", new groovy.json.JsonBuilder(json).toPrettyString())

JSON数据，而 “空”元素将作为${data} JMeter变量提供。

非常感谢Dmitri。但是它捕获了$ {data}中的整个响应。我们只想要捕获JSON响应的非空值。 –
