Jmeter 对Json字符串进行URLEncoder的两种处理

方法一：把json字符串拼接好后，直接在beanshell中调用URLEncoder.encode方法，beanshell如下：

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;

String userInfo="{\"sessionId\":\"${sessionId}\",\"userId\":null,\"token\":\"${token}\"}";
try {      encode = URLEncoder.encode(userInfo, "utf-8");
            vars.put("userInfo",encode);
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
      }

方法二：自定义函数处理，这种方式把函数定义好了之后直接调用就行了，比较方便，不需要太多设置，自定义函数如下

package com.zhongan.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 java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

public class GetEncodeJson extends AbstractFunction {
    private Object[] values;
    private CompoundVariable json;//接受json字符串


    public String execute(SampleResult sampleResult, Sampler sampler) throws InvalidVariableException {
        json = (CompoundVariable) values[0];
        String encodeStr = null;
        try {
            encodeStr = URLEncoder.encode(json.execute().trim(), "UTF-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return encodeStr;
    }

    public void setParameters(Collection<CompoundVariable> collection) throws InvalidVariableException {
        checkParameterCount(collection, 1);
        values = collection.toArray();
    }

    public String getReferenceKey() {
        return "_JsonEncode";
    }

    public List<String> getArgumentDesc() {
        List desc = new ArrayList();
        desc.add("Json String");
        return desc;
    }
}

自定义函数设置好之后，就可以在jmeter中使用了
