方法一:
使用Beanshell 后置处理器实现,现已Base64加密为例,脚本如下:
import sun.misc.BASE64Decoder;
String res =newsun.misc.BASE64Encoder().encode("${token}".getBytes());
vars.put("BASEtoken",res);
ps:${session}:要加密的字符串参数,BASEtoken:加密后的字符串保存在${BASEtoken}参数中
方法二:
步骤:
1、使用rar工具解压JMeterPlugins.jar
2、在相应目录Jmeter\functions下新建java文件Base64.java
3、在classpath中添加Base64.java引用的jar包
;%JAVA_HOME%/lib/ApacheJMeter_core.jar;%JAVA_HOME%/lib/ApacheJMeter_java.jar;%JAVA_HOME%/lib/sun.misc.BASE64Decoder.jar
4、使用javac编译java文件,生成Base64.class文件
javac Base64.java
5、命令行使用jar打包
jar JMeterPlugins.jar kg
将kg包含的内容打包,包名JMeterPlugins.jar
6、将JmeterPlugins.jar复制到jmeter\lib\ext文件夹下,打开jmeter,函数助手中可以看到新增的_Base64函数
${__Base64(${session},)}即为${session}的Base64加密字符串
将Base64做成Jmeter的可以直接调用的函数,这需要用到Jmeter插件开发,为了简化开发,将Base64添加到已开发的JMeterPlugins.jar中
Base64.java文件代码如下:
package kg.apc.jmeter.functions;import java.util.Collection;import java.util.LinkedList;import java.util.List;import org.apache.jmeter.engine.util.CompoundVariable;import org.apache.jmeter.functions.AbstractFunction;import org.apache.jmeter.functions.InvalidVariableException;import org.apache.jmeter.samplers.SampleResult;import org.apache.jmeter.samplers.Sampler;import org.apache.jmeter.threads.JMeterVariables;import sun.misc.BASE64Encoder;publicclassBase64extends AbstractFunction
{
privatestaticfinalList desc =new LinkedList();
privatestaticfinalString KEY = "__Base64";
private Object[] values;
publicsynchronized String execute(SampleResult paramSampleResult, Sampler paramSampler)
throws InvalidVariableException
{
JMeterVariables localJMeterVariables = getVariables();
String str1 = ((CompoundVariable)this.values[0]).execute();
String str2 =new BASE64Encoder().encode(str1.getBytes());
if((localJMeterVariables !=null) && (this.values.length > 1)) {
String str3 = ((CompoundVariable)this.values[1]).execute().trim();
localJMeterVariables.put(str3, str2);
}
return str2;
}
publicsynchronizedvoidsetParameters(Collection paramCollection)
throws InvalidVariableException
{
checkMinParameterCount(paramCollection, 1);
this.values = paramCollection.toArray();
}
public String getReferenceKey()
{
return"__Base64";
}
publicList getArgumentDesc()
{
return desc;
}
static {
desc.add("String to calculate Base64 hash");
desc.add("Name of variable in which to store the result (optional)");
}
}
