本文介绍了一种处理签名参数的方法，特别是如何处理数组类型的参数，并将其转换为字符串进行MD5加密。提供了具体的Java代码实现，展示了如何组织参数、排序及生成最终的签名。

签名传入的参数中包含数组类型的参数，String[] xy = new String[]{”116.288418”, “39.832535”}; 加密过程中需要转换为字符串Arrays.toString(xy)

 public static Map<String, Object> addCommonParams(Map<String, Object> reqMap,Object object){
        if(object instanceof PXOrderInfoDTO){
            PXOrderInfoDTO vo = (PXOrderInfoDTO)object;
            reqMap.put("imei", vo.getImei());
            reqMap.put("version", vo.getVersion());
            reqMap.put("platform", vo.getPlatform());
            reqMap.put("ch", vo.getCh());
            reqMap.put("app_id", vo.getApp_id());
            reqMap.put("client_id", vo.getClient_id());
            reqMap.put("timestamp", vo.getTimestamp());
            reqMap.put("token", vo.getToken1());
        }else if(object instanceof PXRequestVO){
            PXRequestVO vo = (PXRequestVO)object;
            reqMap.put("imei", vo.getImei());
            reqMap.put("version", vo.getVersion());
            reqMap.put("platform", vo.getPlatform());
            reqMap.put("ch", vo.getCh());
            reqMap.put("app_id", vo.getApp_id());
            reqMap.put("client_id", vo.getClient_id());
            reqMap.put("timestamp", vo.getTimestamp());
            reqMap.put("token", vo.getToken1());
        }
        return reqMap;
    }
