C# za pridobitev izvorne kode spletne strani

Admin · Objavljeno na 15. 02. 2015 14:35:51

C# je mogoče pridobiti na tri načine: WebClient, WebRequest in HttpWebRequest.

Seveda lahko uporabite tudi webBrowse! Ne bom gledal, kako pride webBrowse sem.

WebClient

zasebni niz GetWebClient(string url)
{
string strHTML = "";
WebClient myWebClient = novi WebClient();
Stream myStream = myWebClient.OpenRead(url);
StreamReader sr = nov StreamReader(myStream, System.Text.Encoding.GetEncoding("utf-8"));
strHTML = sr. ReadToEnd();
myStream.Close();
vrni strHTML;
}
WebRequest

private string GetWebRequest (string url)
{
Uri uri = nov Uri(url);
WebRequest myReq = WebRequest.Create(uri);
WebResponse result = myReq.GetResponse();
Stream receviceStream = rezultat. GetResponseStream();
StreamReaderOfStream = novi StreamReader(receviceStream, System.Text.Encoding.GetEncoding("utf-8"));
string strHTML = readerOfStream.ReadToEnd();
readerOfStream.Close();
receviceStream.Close();
rezultat. Close();
vrni strHTML;
}
HttpWebRequest

private string GetHttpWebRequest (string url)
{
Uri uri = nov Uri(url);
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(uri);
myReq.UserAgent = "User-Agent:Mozilla/4.0 (združljiv; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705";
myReq.Accept = "*/*";
myReq.KeepAlive = resnično;
myReq.Headers.Add("Accept-Language", "zh-cn,en-us; q=0,5");
HttpWebResponse rezultat = (HttpWebResponse)myReq.GetResponse();
Stream receviceStream = rezultat. GetResponseStream();
StreamReaderOfStream = novi StreamReader(receviceStream, System.Text.Encoding.GetEncoding("utf-8"));
string strHTML = readerOfStream.ReadToEnd();
readerOfStream.Close();
receviceStream.Close();
rezultat. Close();
vrni strHTML;
}
Upoštevajte, da naj "UTF-8" ustreza kodiranju določene spletne strani.

Povzetek

Lahko vidite, da je metoda HttpWebRequest najbolj zapletena, vendar ponuja več izbire.
