使用 HttpURLConnection URL 发送请求，解决字符编码问题

从HttpURLConnection实例将获取服务器返回的输入流写到BufferedReader时，转成utf-8格式。

只需要在设置编码即可 reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"UTF-8"));

代码如下:

public boolean methodName(String userId, String request) {
        try {
            SysConfig sysConfig = sysConfig.getConfigByKey("ID"); //根据ID获取配置数据
            String industryId = sysConfig.getFdStr3();
            Map<String, Object> requestMap = JsonUtil.json2map(request);
            String deptCode = (String) requestMap.get("deptCode");
            SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            JSONObject jsonObj = new JSONObject();
            jsonObj.put("shareRange", 0);// 分享范围: 0不允许分享,1只分享到美信 ，2不限
            jsonObj.put("createTime", formatter.format(new Date()));
            jsonObj.put("openType", 3);// 打开方式：openType=0 pc 移动端都不能打开，openType=1 只支持PC 、 openType=2 只支持移动 、openType=3 既支持PC也支持移动 //必传
            Calendar cale = Calendar.getInstance();
            int month = cale.get(Calendar.MONTH) + 1;
            String coverImgUrl = HrMailUtil.formatUrl("/upload/"+ month + "_month.jpg");
            String jumpUrl = "https://www.baidu.com/";
            jsonObj.put("coverImgUrl", coverImgUrl);// 封面图片
            jsonObj.put("jumpUrl", jumpUrl);// 封面图片
            HrOrgDept hrOrgDept = hrOrgDeptMapper.selectAllDeptLeader(deptCode);
            Map<String, Object> map = null;
            List<HrEmpPersonChangeLog> personLst = new ArrayList<HrEmpPersonChangeLog>();
            HrEmpPersonChangeLog psnLog = null;

            SysConfig config = sysConfigMapper.getConfigByKey("NAME");
            String host = config.getFdStr1();
            String appKey = config.getFdStr2();
            String ACCESS_TOKEN = config.getFdStr3();
            if (null != orgDept && orgDept.size() > 0) {
                deptCode = StringBuQi.buQi(hrOrgDept.getFdCode());
                map = PersonnelChangesGenerator.getInstance().getPersonnelChanges(deptCode);
                String title = this.getMessage("PERSON_CHANGE_INFO");
                title = title.replace("{totalEntry}",(String) map.get("totalEntry")).replace("{totalLeave}", (String) map.get("totalLeave"));
                jsonObj.put("title", title);
                psnLog = new HrEmpPersonChangeLog();
                psnLog.setFdId(IDGenerator.generateID());
                psnLog.setFdContent(jsonObj.toString());
