Question

我正在使用Asp.net MVC，我正在尝试通过将发布数据写入日志文件来调试我的方法。

我接受了这篇文章C# .net equivilent of HTTP_RAW_POST_DATA?并尝试使用它。

这是我的ActionResult：

   public ActionResult Receipt(string id)
    {
      try
      {
        using (var sw = new StreamWriter(@"C:\LOGS\RECEIPTLOG.TXT", true))
        {
          sw.WriteLine("-------------------------------------------");
          sw.WriteLine("Start Receipt: " + DateTime.Now);
          sw.WriteLine("Browser: " + Request.Browser.Id);
          sw.WriteLine("Browser Version: {0}.{1}", Request.Browser.MajorVersion, Request.Browser.MinorVersion);
          sw.WriteLine("Request.UserHostAddress: " + Request.UserHostAddress);
          if (Request.UrlReferrer != null)
          {
            sw.WriteLine("Request.UrlReferrer: " + Request.UrlReferrer);
          }

          foreach (var headerKey in Request.Headers.Keys)
          {
            var headerValues = Response.Headers.GetValues(headerKey.ToString());
            if (headerValues != null)
            {
              sw.WriteLine("Response Header: {0}, Value: {1}", headerKey, String.Join(";", headerValues));
            }
          }
        }
      }
      catch (Exception ex)
      {
        Console.WriteLine("error:" + ex.Message);
      }

      var control = Logging.StartLog();
      control.Source = SourceEnum.WebPortal;

      try
      {
        Logging.WriteLog("Start Receipt");

        var count = 0;
        var postVals = new Dictionary<string, string>();
        foreach (var key in Request.Form.AllKeys)
        {
          Logging.WriteLog("count: " + count);
          Logging.WriteLog(string.Format("key:   {0}    Value:   {1}", key, Request.Form[key]));
          postVals.Add(key, Request.Form[key]);
          Logging.WriteLog("finished count: " + count);
          count++;
        }
        Logging.WriteLog("finished processing ALLKeys");
        var paymentReq = createPaymentRequest(postVals);
        Logging.WriteLog("finished processing 'var paymentReq = createPaymentRequest(postVals)' ");

        Logging.WriteLog("_client.RecordPaymentWithRequest start");
        var receipt = _client.RecordPaymentWithRequest(paymentReq);
        Logging.WriteLog("Running _client.RecordPaymentWithRequest complete");
        var retval = PartialView(receipt.Duplicate ? "Duplicate Receipt" : "Receipt", receipt);
        Logging.WriteLog(string.Format("retval: {0}", retval));
        return retval;
      }
      catch (Exception ex)
      {
        Logging.WriteException(ex);
        throw;
      }
      finally
      {
        Logging.WriteLog(control, "End RegisterNewAccountEmail");

        try
        {
          using (var sw = new StreamWriter(@"C:\LOGS\RECEIPTLOG.TXT", true))
          {
            sw.WriteLine("Stop Receipt: " + DateTime.Now);
          }
        }
        catch (Exception ex)
        {
          Console.WriteLine("error:" + ex.Message);
        }

      }
    }

这就是我的日志中的内容：

-------------------------------------------
Start Receipt: 1/14/2014 7:17:07 AM
Browser: internetexplorer
Browser Version: 11.0
Request.UserHostAddress: xxx.xxx.xxx.xxx
Request.UrlReferrer: website url here
Stop Receipt: 1/14/2014 7:17:07 AM

正如您所看到的，没有写入标题信息。

我是否将此错误转移到日志文件中？如果没有，为什么我的标题信息没有写入日志？

**更新**

我在第一次尝试/捕获时将其添加到我的日志中：

sw.WriteLine("Request.Headers.Keys.Count: " + Request.Headers.Keys.Count);

这就是结果：

Request.Headers.Keys.Count: 11

Answer 1

使用Request.Headers.AllKeys而不是Keys。

AllKeys返回一个你想要的字符串数组 Keys会返回NameObjectCollectionBase.KeysCollection Class

从请求获取发布数据将返回null
