Httpcontext在await函数中变为null [英] Httpcontext is getting null inside await function

问题描述

以下是使用异步等待的示例。

当我们执行任何代码时，等待httpcontext变为空



我尝试过：

Below is the sample of using async await.
when ever we execute any code inside await httpcontext is getting null

What I have tried:

//Here is the sample of Async Function in which i cant get Httpcontext
    public async Task<string> Get(int id)
    {
		  var x = HttpContext.Current;

		  if (x == null)
		  {
			  // not thrown
			  throw new ArgumentException("HttpContext.Current is null");
		  }

		  await Task.Run(() => { GetRealId(); });

		return "value";
     }

    //HttpContext Getting null here..
    public void GetRealId()
    {
		  var r = HttpContext.Current;
    }

推荐答案

简单的艺术：ASP.NET Web API：HttpContext.Current在任务内部为null [ ^ ]（5秒google搜索结果）

The art of simplicity: ASP.NET Web API: HttpContext.Current is null inside Task[^] (result of 5 seconds of googling)

您需要将httpcontext存储在函数范围之外，如类成员或静态。



我想它可能会超时。设置更高的超时。

You need to store the httpcontext outside the scope of your function like a class member or as static.

I guess it may timed out. Set the timeouts higher.
