url传递json串参数及后台处理【我】

用url请求向后台传参时，如果参数是一个对象序列成的json传，直接传递会报错，可以用 encodeURIComponent 进行转码【将json中的{}等特殊符号转码】后再传递，java后台基本不用特殊处理。

js页面跳转：

window.location.href = ctxPath + '/order/custOperate!toAddCust.action?custJson=' + encodeURIComponent(JSON2.stringify(custObj))

java后台处理解析：

package com.test;

import java.util.List;
import java.util.Map;

import com.alibaba.fastjson.JSONObject;

public class Json1 {

    public static void main(String[] args) {

//        String reqJson = _request.getParameter("reqJson");
        String reqJson = "{\"idExpDate\":\"2099-12-31\",\"partyName\":\"华夏银行股份有限公司\",\"partyNumber\":\"BJ2018122110041065\",\"identityType\":\"2\",\"custTree\":{\"custTreeTopNodeCode\":\"100207\",\"controlArea\":\"\",\"controlAreaTop\":\"\",\"custTreeTopName\":\"华夏银行股份有限公司\",\"custTreeNodeCode\":\"100207\",\"controlDepTop\":\"13007005\",\"controlTypeTop\":\"13013001\",\"controlType\":\"13013001\",\"custTreeName\":\"华夏银行股份有限公司\",\"controlDep\":\"13007005\"},\"orgUscc\":\"9111000010112001XW\",\"partyCert\":[{\"certNum\":\"qazwsxed3\",\"certType\":\"\",\"partyCertId\":\"259941363\"},{\"certNum\":\"9111000010112001XW\",\"certType\":\"49\",\"partyCertId\":\"820108430\"}],\"industryCd\":\"DD0302\",\"isAvailable\":\"1\",\"idEffDate\":\"1992-10-14\",\"industryTypeId\":\"177\",\"orgStatusCd\":\"4\",\"partyId\":\"259941363\",\"registerAddr\":\"北京市东城区建国门内大街22号\"}";
        JSONObject jsonData = JSONObject.parseObject(reqJson);
        String partyName = String.valueOf(jsonData.get("partyName"));
        List<Map<String, String>> partyCertList = (List<Map<String, String>>) jsonData.get("partyCert");
        for (int i = 0; i < partyCertList.size(); i++) {
            Map partyCertMap = partyCertList.get(i);
            System.out.println(partyCertMap);
        }
    }
}
