angularjs – 无法获取从角度到节点服务器发送的表单数据

$scope.saveInfo = function(){
  var formData = new FormData;
  console.log('update function');
  for(key in $scope.seller){
    formData.append(key,$scope.seller[key]);
  }
  console.log(key,$scope.seller);
  var file = $('#file')[0].files[0];
  formData.append('image',filE);

  $http.put('/api/seller/businessInformation',formData,{
    transformrequest: angular.Identity,headers: {
      'Content-type': undefined
    }
  }).then(function(res){

  });
}

解决方法

console.log(req.files.file.Name);

var a = JSON.parse(req.body.Name);
console.log(a);
