  • jmeter添加自定义扩展函数之MD5加密

    1,打开eclipse,新建maven工程,在pom中引用jmeter核心jar包,具体请看---https://www.cnblogs.com/guanyf/p/10863033.html---,这里就不再赘述

    2,代码如下:

    package com.mytest.functions;
    
    
    
    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 org.apache.jorphan.util.JOrphanUtils;
    
    
    
    import java.security.MessageDigest;
    
    import java.security.NoSuchAlgorithmException;
    
    import java.util.Collection;
    
    import java.util.LinkedList;
    
    import java.util.List;
    
    
    
    public class MD5 extends AbstractFunction {
    
    
    
        private static final List<String> desc = new LinkedList<String>();
    
        private static final String KEY = "__MD5";
    
    
    
        static {
    
            desc.add("String to calculate MD5 hash");
    
            desc.add("Name of variable in which to store the result (optional),作者:管永飞");
    
        }
    
    
        private Object[] values;
        public MD5() {
    
        }
    
        @Override
    
        public synchronized String execute(SampleResult previousResult, Sampler currentSampler)
    
                throws InvalidVariableException {
    
            JMeterVariables vars = getVariables();
    
            String str = ((CompoundVariable) values[0]).execute();
    
            MessageDigest digest;
    
            try {
    
                digest = MessageDigest.getInstance("md5");
    
            } catch (NoSuchAlgorithmException ex) {
    
                return "Error creating digest: " + ex;
    
            }
    
            String res = JOrphanUtils.baToHexString(digest.digest(str.getBytes()));
            if (vars != null && values.length > 1) {
    
                String varName = ((CompoundVariable) values[1]).execute().trim();
    
                vars.put(varName, res);
            }
            return res;
    
        }
        @Override
    
        public synchronized void setParameters(Collection<CompoundVariable> parameters) throws InvalidVariableException {
    
            checkMinParameterCount(parameters, 1);
    
            values = parameters.toArray();
    
        }
        
        @Override
    
        public String getReferenceKey() {
    
            return KEY;
    
        }
    
        @Override
    
        public List<String> getArgumentDesc() {
    
            return desc;
    
        }
    
    }
