Httpcontext在await函数中变为null

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;
    }
