export default {
  encrypt,

headerParams封装在baseUrl.js文件中

export const baseUrl = 'http://10.29.32.19:8088/bmp/payment/';

export const headerParams = (name, data) => {
  if (!data) {
    data = {};
  };
  let headerParams = {
    charset: 'utf-8',
    method: 'com.taiping.cashier.' + name,
    signature: '',
    timestamp: new Date().getTime(),
    transId: '',
    version: '2.0',
    requestData: data
  };
  return headerParams;
};
