节点肥皂结果是深层嵌套对象，而不是普通结果

Question

我使用node-soap请求SOAP-API。但是结果却不是我所期望的。 如果我使用PHP请求相同的请求，它将按预期工作（所有api示例都在php中）。 但是我的应用程序/服务是用JavaScript（ExpressJS）编写的。

我的请求代码非常简单：

         public async Task<IActionResult> Edit(int id, 
         [Bind("RouteStopId,BusRouteCode,BusStopNumber,OffsetMinutes")] 
         RouteStop 
         routeStop)
       {
        if (id != routeStop.RouteStopId)
        {
            return NotFound();
        }

        if (ModelState.IsValid)
        {
            try
            {
                _context.Update(routeStop);
                await _context.SaveChangesAsync();
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!RouteStopExists(routeStop.RouteStopId))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }
            return RedirectToAction(nameof(Index));
        }
        ViewData["BusRouteCode"] = new SelectList(_context.BusRoute, 
        "BusRouteCode", "BusRouteCode", routeStop.BusRouteCode);
        ViewData["BusStopNumber"] = new SelectList(_context.BusStop, 
        "BusStopNumber", "BusStopNumber", routeStop.BusStopNumber);
        return View(routeStop);

       CLubs (Edit):-
         if (id != club.ClubId)
        {
            return NotFound();
        }

        if (ModelState.IsValid)
        {
            try
            {
                _context.Update(club);
                await _context.SaveChangesAsync();
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!ClubExists(club.ClubId))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }
            return RedirectToAction(nameof(Index));
        }
        ViewData["StyleCode"] = new SelectList(_context.Style, 
         "StyleCode", 
         "StyleCode", club.StyleCode);
        return View(club); 
        } 

结果如下：

var url = '...wsdl';
var args = {
    Params: JSON.stringify({
      User: '...',
      AuthType: 'session',
      AuthData: '...',
      RequestType: 'get_mailaccounts',
      RequestParams: []
    })
};
soap.createClient(url, function(err, client) {
    client.Api(args, function(err, result, rawResponse, soapHeader, rawRequest) {
      console.log(util.inspect(result, {showHidden: false, depth: null}));
    });
});

该对象包含的信息可以，并且可以预期。但是为什么嵌套这么奇怪呢？我从上述PHP代码获得的结果对象如下所示：

      "xsi:type": "ns2:Map"

                          "xsi:type": "xsd:string"
                        }
                      }
                    },
                  ]
                }
              }
            }
          ]
        }
      }
    ]
  }
}

这就是我想要的。
