我正在使用HTTP Web請求，響應從jenkins服務器獲取url響應。讀取響應並使用Filestream將其存儲在本地驅動器中。當響應是連續的，我可以成功下載並安裝exe文件。文件大小下載大於400MB如何避免/跳過HTTP響應中的異常，在c＃中的文件下載期間添加爲字節
問題場景：雖然讀取有時會發生超時，但會引發異常。響應閱讀器也讀取該異常並存儲在文件中。
例外：

如何避免讀取例外字節，這樣我可以對剩餘的字節再繼續下載。
這裏是我的邏輯：
try
{
long iFileSize = 0;
int iBufferSize = 1024;
iBufferSize *= 1000;
long iExistLen = 0;
if (System.IO.File.Exists(path))
{
System.IO.FileInfo fINfo =
new System.IO.FileInfo(path);
iExistLen = fINfo.Length;
}
if (iExistLen > 0)
saveFileStream = new System.IO.FileStream(path,
System.IO.FileMode.Append, System.IO.FileAccess.Write,
System.IO.FileShare.None);
else
saveFileStream = new System.IO.FileStream(path,
System.IO.FileMode.Create, System.IO.FileAccess.Write,
System.IO.FileShare.None);
HttpWebRequest hwRq1 =(HttpWebRequest)System.Net.HttpWebRequest.Create(urlAddress);
hwRq1.AddRange((int)iExistLen);
using (HttpWebResponse hwRes=(System.Net.HttpWebResponse)hwRq1.GetResponse())
{
using (System.IO.Stream smRespStream = hwRes.GetResponseStream())
{
smRespStream.ReadTimeout = 60000;
iFileSize = hwRes.ContentLength;
int iByteSize;
byte[] downBuffer = new byte[iBufferSize];
while ((iByteSize = smRespStream.Read(downBuffer, 0, downBuffer.Length)) > 0)
{
saveFileStream.Write(downBuffer, 0, iByteSize);
Console.WriteLine(iExistLen.ToString());
}
saveFileStream.Close();
smRespStream.Close();
if (iByteSize == 0 && !FileSizeCheck(path, softwareWithSize.Value))
return new Tuple<string, bool>("Zero byte received", false);
}
}
感謝您的回覆，我使用原始文件和錯誤文件之間的二進制比較器來獲取異常 – guru
我沒有編程方式來檢測發生錯誤，您需要檢查每個文件的末尾下載以查找ascii錯誤文本並將其刪除 –
