jmeter接口测试之使用rsa算法加密解密的代码
作者：大虫测试
这篇文章主要介绍了jmeter接口测试-使用rsa加密解密算法,部分接口采用了rsa加密算法，我们的jmeter 也是可以直接拿来调用的，不需要开发配合去掉加密代码，需要的朋友可以参考下
本篇介绍jmeter 使用rsa算法进行加密参数
如果测试过程中，部分接口采用了rsa加密算法，我们的jmeter 也是可以直接拿来调用的，不需要开发配合去掉加密代码！
直接上代码

System.out.println(result);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
print(result);
vars.put("sign",result);
return result;看运行效果
上述代码，直接把加密结果放入变量sign中，在其他地方，如果需要调用加密结果，只需要 使用代码：${sign}即可
import org.apache.commons.codec.binary.Base64;
引入了jmeter包中的类，如果本代码在jmeter环境运行，不需要加载第三方jar包
如果在eclipse 或者其他环境中运行，需要其他base64的类替换，请注意！
