AngularJs如何从ASP.MVC5下载文件传递参数

app.controller('DownloadController', function($scope, $http) {
  $scope.downloadFile = function() {
    var parameter = 'your_parameter_value'; // 替换为实际的参数值
    var url = '/Download/File?parameter=' + parameter; // 替换为实际的后端路由地址

    $http.get(url, { responseType: 'arraybuffer' })
      .then(function(response) {
        var data = new Blob([response.data], { type: 'application/octet-stream' });
        var downloadLink = document.createElement('a');
        downloadLink.href = URL.createObjectURL(data);
        downloadLink.download = 'file_name.extension'; // 替换为实际的文件名和扩展名
        downloadLink.click();
      })
      .catch(function(error) {
        console.log('Error downloading file:', error);
      });
  };
});

<button ng-click="downloadFile()">下载文件</button>
