WCF城客戶端代理離開溝道開

Question

我使用WCF城堡設施使用以下配置來初始化客戶端代理：

<component 
id="ComponentID" 
type="SomeType, SomeType" 
wcfEndpointConfiguration="WCFConfig" 
lifestyle="PerWebRequest" > 
</component> 

我遇到的問題是，在現場，我結束了一個大內存泄漏。使用內存分析器分析了這一點後，我似乎在內存中留下了大量的WCF通道。我期望Castle WCF Facility在Web請求結束時清理它嗎？

如果你使用生活方式perwebrequest，你需要確保HttpContext不會在整個請求中重新創建。如果是，那麼你需要傳遞HttpContext.Items，因爲Castle http模塊使用它來跟蹤組件。

例如

改變了這個：

public CapturedViewResult Capture(ControllerContext controllerContext, Func<ActionResult> action) 
    { 
     CapturedViewResult capturedViewResult = new CapturedViewResult(); 

     HttpContext currentContext = HttpContext.Current; 

     using (StringWriter stringWriter = new StringWriter(CultureInfo.InvariantCulture)) 
     { 
      HttpResponse response = new HttpResponse(stringWriter); 
      HttpContext context = new HttpContext(currentContext.Request, response) { User = currentContext.User }; 
      context.Items["LocalizationContext"] = currentContext.Items["LocalizationContext"]; 

      HttpContext.Current = context; 

      ViewResult result = action.Invoke() as ViewResult; 

      if (result != null) 
      { 
       capturedViewResult.ViewName = result.ViewName; 
       result.ExecuteResult(controllerContext); 
      } 
      else 
      { 
       throw new ArgumentException("Supplied controller action method did not return a ViewResult", "action"); 
      } 

      HttpContext.Current = currentContext; 

      capturedViewResult.CapturedHtml = stringWriter.ToString(); 
     } 

     return capturedViewResult; 
    } 

要這樣：

public CapturedViewResult Capture(ControllerContext controllerContext, Func<ActionResult> action) 
    { 
     var capturedViewResult = new CapturedViewResult(); 

     var currentContext = HttpContext.Current; 

     using (var stringWriter = new StringWriter(CultureInfo.InvariantCulture)) 
     { 
      var response = new HttpResponse(stringWriter); 
      var context = new HttpContext(currentContext.Request, response) { User = currentContext.User }; 

      foreach (var key in currentContext.Items.Keys) 
      { 
       context.Items.Add(key, currentContext.Items[key]); 
      } 

      HttpContext.Current = context; 

      var result = action.Invoke() as ViewResult; 

      if (result != null) 
      { 
       capturedViewResult.ViewName = result.ViewName; 
       result.ExecuteResult(controllerContext); 
      } 
      else 
      { 
       throw new ArgumentException("Supplied controller action method did not return a ViewResult", "action"); 
      } 

      foreach (var key in context.Items.Keys) 
      { 
       currentContext.Items[key] = context.Items[key]; 
      } 

      HttpContext.Current = currentContext; 

      capturedViewResult.CapturedHtml = stringWriter.ToString(); 
     } 

     return capturedViewResult; 
    }
