AngularJS基于http请求实现下载php生成的excel文件功

// 创建a标签模拟下载
function exportExcel(params, filename) {
  return $http({
    url: '/api/exportExcel',
    method: "POST",
    headers: {
      'Content-type': 'application/json'
    },
    params: params,
    responseType: 'arraybuffer'
  }).suess(function (data) {
    var blob = new Blob([data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"});
    var objectUrl = URL.createObjectURL(blob);
    var a = document.createElement('a');
    document.body.appendChild(a);
    a.setAttribute('style', 'display:none');
    a.setAttribute('href', objectUrl);
    a.setAttribute('download', filename);
    a.click();
    URL.revokeObjectURL(objectUrl);
  });
}

// 生成下载url
$scope.data.down_url = "../c_potential/get_excel?end_time="+$scope.end_date+"&liable="+liable+"&nickname="+$scope.data.nickname+"&province="+$scope.data.province_cur+"&start_time="+$scope.start_date;
