我需要在我的路由器中讀取一個位置,但我得到以下異常 - ServerProtocolViolation「服務器提交了違反協議的情況,Section = ResponseHeader Detail = CR後面必須跟LF」C#:處理WebClient「違反協議」
這發生在我使用.DownloadString(url)函數時。有沒有辦法讓WebClient忽略協議違規?谷歌搜索告訴我,我應該在某處設置useUnsafeHeaderParsing選項。我可以通過程序來完成嗎?如果我使用它,有什麼收穫?
編輯:附加代碼 -
public Readlog() {
WebClient wc = new WebClient();
string url = @"http://192.168.0.1/setup.cgi?next_file=log.htm&todo=cfg_init";
Console.WriteLine(url);
try {
//wc.Headers.Add("User-Agent", "Mozilla/5.0(Windows; U; Windows NT 5.2; rv:1.9.2) Gecko/20100101 Firefox/3.6");
wc.Credentials = new NetworkCredential("admin", "admin");
//Next line causes exception System.Net.WebException
//Message - "The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF"
//May be I need to use useUnsafeHeaderParsing somehow to avoid that
string result = wc.DownloadString(url);
Console.WriteLine(result);
} catch (WebException we) {
System.Diagnostics.Trace.WriteLine(we.ToString());
}
}
您可能希望將代碼粘貼到您的問題中。 – 2010-06-29 15:55:05
