Question

我正在尝试构建一些ASP.Net核心中间件。

需要查看当前路线是否标记为[授权]。

例如：

var SSID='SpreadsheetID';
var sheetName='Sheet Name';
function htmlSpreadsheet(mode)
{
  var mode=(typeof(mode)!='undefined')?mode:'dialog';
  var br='<br />';
  var s='';
  var hdrRows=1;
  var ss=SpreadsheetApp.openById(SSID);
  var sht=ss.getSheetByName(sheetName);
  var rng=sht.getDataRange();
  var rngA=rng.getValues();
  s+='<table>';
  for(var i=0;i<rngA.length;i++)
  {
    s+='<tr>';
    for(var j=0;j<rngA[i].length;j++)
    {
      if(i<hdrRows)
      {
        s+='<th id="cell' + i + j + '">' + '<input id="txt' + i + j + '" type="text" value="' + rngA[i][j] + '" size="10" onChange="updateSS(' + i + ',' + j + ');" />' + '</th>';
      } 
      else
      {
        s+='<td id="cell' + i + j + '">' + '<input id="txt' + i + j + '" type="text" value="' + rngA[i][j] + '" size="10" onChange="updateSS(' + i + ',' + j + ');" />' + '</th>';
      }
    }
    s+='</tr>';
  }
  s+='</table>';
  //s+='<div id="success"></div>';
  s+='</body></html>';
  switch (mode)
  {
    case 'dialog':
      var userInterface=HtmlService.createHtmlOutputFromFile('htmlss').setWidth(1000).setHeight(450);
      userInterface.append(s);
      SpreadsheetApp.getUi().showModelessDialog(userInterface, 'Spreadsheet Data for ' + ss.getName() + ' Sheet: ' + sht.getName());
      break;
    case 'web':
      var userInterface=HtmlService.createHtmlOutputFromFile('htmlss').setWidth(1000).setHeight(450);
      return userInterface.append(s).setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
   }
}

function updateSpreadsheet(i,j,value)
{
  var ss=SpreadsheetApp.openById(SSID);
  var sht=ss.getSheetByName(sheetName);
  var rng=sht.getDataRange();
  var rngA=rng.getValues();
  rngA[i][j]=value;
  rng.setValues(rngA);
  var data = {'message':'Cell[' + Number(i + 1) + '][' + Number(j + 1) + '] Has been updated', 'ridx': i, 'cidx': j};
  return data;
}

function doGet()
{
  var output=htmlSpreadsheet('web');
  return output;
}

有谁知道如何实现这一目标，或者甚至可能实现这一目标？

如果没有，那么什么是一个好的替代方法呢？

Answer 1

Without knowing exactly what you want to achieve, it's a bit tricky to answer, but I suggest you have a look at the controller filters : https://docs.microsoft.com/en-us/aspnet/core/mvc/controllers/filters

I put together an example:

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services
        .AddMvc()
        .AddMvcOptions(options => options.Filters.Insert(0, new CustomFilter()));
}

CustomFilter.cs

public class CustomFilter : IActionFilter
{
    public void OnActionExecuting(ActionExecutingContext context)
    {
        if(context.HttpContext.Request.Path.Value.StartsWith("/api"))
        {
            var controllerInfo = context.ActionDescriptor as ControllerActionDescriptor;
            var hasAuthorizeAttr = controllerInfo.ControllerTypeInfo.CustomAttributes.Any(_ => _.AttributeType == typeof(AuthorizeAttribute));
        }
    }

    public void OnActionExecuted(ActionExecutedContext context)
    {
        // NOP
    }
}

Answer 2

只是自我回答以解决问题。

似乎没有可能这样做，因为它太早了。

Answer 3

我相信可以通过以下方式在中间件类中实现：

var hasAuthorizeAttribute = context.Features.Get<IEndpointFeature>().Endpoint.Metadata
                .Any(m => m is AuthorizeAttribute);
