如何在Event Handler中获取HttpContext [英] How to obtain the HttpContext in Event Handler

问题描述

我试图在 MOSS 的文档库中的事件处理程序中获取 HTTPContext，但我所拥有的只是 HTTPContext.Current 的空值，我对 List 执行相同的操作并返回 HTTPContext.有没有办法获取文档库中的 HTTPContext 来访问 HTTPContext.Request 方法?

I’m trying to obtain the HTTPContext within an Event Handler in a Document Library in MOSS, but all I have is a null value of the HTTPContext.Current, I do the same thing on a List and the HTTPContext is returned. There is a way to obtain the HTTPContext in Document Libraries to access the HTTPContext.Request method?

感谢您的帮助

代码如下:

public class TestContextListItemEventReceiver : SPItemEventReceiver
{
    HttpContext current;
    static object obj;

    /// <summary>
    /// Initializes a new instance of the Microsoft.SharePoint.SPItemEventReceiver class.
    /// </summary>
    public TestContextListItemEventReceiver()
    {
        current = HttpContext.Current;
    }

    public override void ItemAdding(SPItemEventProperties properties)
    {
        obj = current;  
    }
}

推荐答案

步骤 1声明:

    private HttpContext currentContext;
    static HttpContext _stCurrentContext;

第 2 步

currentContext = HttpContext.Current;      // in constructor

第三步

public override void ItemAdding(SPItemEventProperties properties)
                 _stCurrentContext = currentContext;

第四步

 public override void ItemAdded(SPItemEventProperties properties)
 if (_stCurrentContext.Request.Files[0].ContentLength > 0)
 HttpPostedFile uploadfile = _stCurrentContext.Request.Files[0];
