我是C#中的新成员,并且需要从C#中检索URL。大多数情况下它工作正常,但在一种情况下,它会抛出一个错误。 URL是如下 http://whois.afrinic.net/cgi-bin/whois?searchtext=41.132.178.138HttpWebRequest错误403
错误是:禁止(403):
异常在对URL的HTTP请求:http://whois.afrinic.net/cgi-bin/whois?searchtext=41.132.178.138远程服务器返回一个错误。
我的代码
void MyFUnction(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.UserAgent = ".NET Framework Test Client";
request.ContentType = "application/x-www-form-urlencoded";
Logger.WriteMyLog("application/x-www-form-urlencoded");
// execute the request
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
// we will read data via the response stream
Stream resStream = response.GetResponseStream();
string tempString = null;
int count = 0;
do
{
// fill the buffer with data
count = resStream.Read(buf, 0, buf.Length);
// make sure we read some data
if (count != 0)
{
// translate from bytes to ASCII text
tempString = Encoding.ASCII.GetString(buf, 0, count);
if (httpData == null)
httpData = tempString;
else
httpData += tempString;
}
}
while (count > 0); // any more data to read?
}
格式化你的代码,在编辑器中选择它,按下Control-K。 – 2010-07-12 19:42:09
