url傳遞json串參數及后台處理【我】

 

用url請求向后台傳參時，如果參數是一個對象序列成的json傳，直接傳遞會報錯，可以用 encodeURIComponent 進行轉碼【將json中的{}等特殊符號轉碼】后再傳遞，java后台基本不用特殊處理。

js頁面跳轉：

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

 

java后台處理解析：

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\":\"華夏銀行股份有限公司\",\"partyNumber\":\"BJ2018122110041065\",\"identityType\":\"2\",\"custTree\":{\"custTreeTopNodeCode\":\"100207\",\"controlArea\":\"\",\"controlAreaTop\":\"\",\"custTreeTopName\":\"華夏銀行股份有限公司\",\"custTreeNodeCode\":\"100207\",\"controlDepTop\":\"13007005\",\"controlTypeTop\":\"13013001\",\"controlType\":\"13013001\",\"custTreeName\":\"華夏銀行股份有限公司\",\"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\":\"北京市東城區建國門內大街22號\"}";
        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);
        }
    }
}
