signData static method

dynamic signData(Object params, dynamic tokenStr)

Implementation

static signData(Object params, tokenStr) async {
  var time = new DateTime.now().millisecondsSinceEpoch;
  String token = tokenStr;
  Map<String, dynamic> reqData = new Map();
  Map<String, dynamic>? paramsObj = new Map();
  paramsObj = params as Map<String, dynamic>?;
  var arr = [];
  //将字典转成数组
  paramsObj?.forEach((key, value) => arr.add(key));
  //进行签名校验
  Map cr = new Map();
  cr['token'] = token;
  cr['time'] = time.toString();
  cr['reqData'] = json.encode(paramsObj);
  var array = [];
  cr.forEach((key, value) => array.add(key));
  array.sort();
  var str = '';
  for (var i = 0; i < array.length; i++) {
    var key = array[i];
    var value = cr[key];
    str += key + value;
  }

  reqData["time"] = time;
  reqData["token"] = token;
  reqData['reqData'] = params;
  reqData['sign'] = generateMd5(str);

  return reqData;
