function getRequest(url, params) {
  return new Promise((resolve, reject) => {
    Vue.$http.get(
      url,
      {
        params: params
      },
      {emulateJSON: true}
    )
    .then((res) => {   //成功的回撥
      resolve(res);
    })
    .catch((res) => {  //失敗的回撥
      reject(res);
    });
  });
}
 

vue的get請求傳遞引數的時候要用{params:{id:'1'}},這樣來傳遞引數，否則就無法傳遞引數；
