需要从Json文件发送一个属性作为http请求的输入

Question

我已经使用beanshell脚本解码了一个响应并将其保存在一个XML文件中。

BeanShell的后置处理程序脚本

import org.apache.commons.io.FileUtils; 
import org.apache.commons.codec.binary.Base64; 

String response= vars.get("data"); 
vars.put("response",new String(Base64.decodeBase64(response))); 

Output = vars.get("response"); 

f = new FileOutputStream("E:/JMeter/apache-jmeter-3.1/bin/response.xml"); 
p = new PrintStream(f); 
this.interpreter.setOut(p); 
print(Output); 
f.close(); 

响应

现在我需要只发送_org价值，这是强调，作为输入到另一个HTTP请求。有什么建议么？

Answer 1

我建议切换到JSR223 PostProcessor和Groovy语言：

• Groovy中内置了Base64 encoding/decoding support
• Groovy中内置了JSON support
• Groovy是更多的Java兼容
• 的Groovy性能比Beanshell好得多

所以，你可以得到你的_org值那样简单：

def response = vars.get("data") 

def decodedResponse = new String(response.decodeBase64()) 

def json = new groovy.json.JsonSlurper().parseText(decodedResponse) 

log.info(json._org)
