如果这是一个副本,请提前抱歉,但我尝试了很多线程,但似乎没有任何解决方案可以帮助我。因此,我发布它的原因。
我正在使用异步 HttpWebRequest.BeginGetResponse 并且在回调函数中我调用的是Response.Redirect,它会抛出以下异常 在此上下文中无法获得响应
我曾尝试使用JavaScript来进行重定向,但这种方法效果不佳。以下是我的代码。
private void GET_PersonalDetails()
{
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
RequestState myRequestState = new RequestState();
myRequestState.request = myHttpWebRequest;
myRequestState.setHeaders();
IAsyncResult result = (IAsyncResult)myHttpWebRequest.BeginGetResponse(
new AsyncCallback(RespCallback), myRequestState);
}
private void RespCallback(IAsyncResult asynchronousResult)
{
try
{
// State of request is asynchronous.
RequestState myRequestState = (RequestState)asynchronousResult.AsyncState;
HttpWebRequest myHttpWebRequest = myRequestState.request;
myRequestState.response =
(HttpWebResponse)myHttpWebRequest.EndGetResponse(asynchronousResult);
// Read the response into a Stream object.
string res = Utility.ReadResponse(myRequestState.response);
Response.Redirect("decision.aspx");
ClientScript.RegisterStartupScript(GetType(), "hwa", "alert('do something');", true);
Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "redirect();", true);
return;
}
catch(WebException e){}
}
