所以这个应用程序在 Visual Studio 中无缝运行，但是我为遇到错误的程序创建了一个安装程序。我想我已经确定了问题所在。当收到一个 POST 时，它会被处理，这会启动一个单独的解耦过程，该过程最终会从网页处理/关闭中中止。
程序流程是这样的
- 收到 POST
context.Request.HttpMethod == "POST", - 提取并写入磁盘的相关 xml 信息，
csfireEyeHandler.DonJobOnLastIp(),- 在后台运行的监视器会接收文件创建事件“void OnChanged”并开始运行基于 XML 文档的服务
FileAdded-->readerRef.ReadInServices(e.FullPath, false)。
问题是在处理 POST 后，它会导致服务因 ThreadAbortException 而中止。如果handler.ProcessRequest(context)在服务完成后延迟，我想是因为页面仍然打开。我无法弄清楚如何正确处理这种情况，调试起来非常困难，因为我无法在 VS 中发生错误。

var stream = context.Request.InputStream;
var buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
var xml = Encoding.UTF8.GetString(buffer);
FileManage.WriteToFile(xml, @"C:\ECC_output\fireEye.xml");
var csfireEyeHandler = new FireEyeService { config = extension + ".config" };
csfireEyeHandler.Load();
csfireEyeHandler.DonJobOnLastIp();
context.Response.StatusCode = 202;
}
