我的情况快把我逼疯了,而且网上没有任何真正有帮助的信息。
我正在自动化一个手动上传文件的过程。实际上,我在3年前写了这段代码,它工作了一年没有任何故障,现在它断断续续地失败了。在查看Fiddler流量中我的请求和刚刚从浏览器发出的请求时,我看到的唯一不同之处在于,在fiddler中,我会在自动调用期间看到这个红色圆圈,其中有一条线穿过它两次。
我的研究表明,这个图标意味着客户端中止了会话--我没有这么做。我为每个请求传递相同的CookieContainer对象。我不知道为什么会发生这种情况,但如果我在Fiddler中查看记录的行的属性,它会为我的自动请求显示以下内容:
SESSION STATE: Aborted.
...
X-ABORTED-WHEN: SendingResponse
...

ClientDoneResponse: 16:25:59.268我在浏览器中得到的日志中的相同行如下所示:

ClientBeginResponse: 10:33:12.511
ClientDoneResponse: 10:33:12.514所以“完成”vs.“已中止”。我从来没有对请求调用过Abort,也没有得到任何异常。下面是我的代码,其中发生了中止:
using (WebResponse httpResponse = httpRequest.GetResponse())
{
if (!httpResponse.ResponseUri.AbsoluteUri.Equals(string.Format("{0}main.htm", url), StringComparison.CurrentCultureIgnoreCase))
{
throw new Exception("Log in failed. Check the Username and Password information in the Setting table.");
}
httpResponse.Close();
}我试着去掉了"using“(即使它是推荐的)和"Close”(也是推荐的),但它仍然被中止。
我很感激

我遇到了这个问题,我意识到如果响应流没有被读取(或访问),Fiddler中的请求将报告它已中止。对于我的用例,我不一定需要读取响应流,但我添加了一些代码来读取响应流(我没有缓冲或保存它),然后Fiddler报告请求已经完成。上面的代码没有读取响应流,所以我会尝试这样做。
using (WebResponse httpResponse = httpRequest.GetResponse())
{
if (!httpResponse.ResponseUri.AbsoluteUri.Equals(string.Format("{0}main.htm", url), StringComparison.CurrentCultureIgnoreCase))
{
throw new Exception("Log in failed. Check the Username and Password information in the Setting table.");
}
var responseStream = httpResponse.GetResponseStream();
if (null != responseStream)
{
var buffer = new byte[8192];
while (responseStream.Read(buffer, 0, buffer.Length) > 0)
{
// Do nothing here.
}
}
httpResponse.Close();
