1、方法一:usingSystem.Text;usingSystem.Net;privatestringgetHtml(stringurl){WebClientmyWebClient=newWebClient();byte[]myDataBuffer=myWebClient.DownloadData(url);returnEncoding.Default.GetString(myDataBuffer);}方法二:publicstringgetHttp(stringHttpUrl,stringReferer
2、Url){stringhtml="";try{MSXML2.XMLHTTPHttp=newMSXML2.XMLHTTPClass();xmlhttp.open("GET",Url,false,null,null);Http.open("GET",HttpUrl,false,null,null);Http.setRequestHeader("Referer",RefererUrl);//Http.setRequestHeader("Referer",RefererUrl);Http.setRequest
3、Header("Content-Type","text/html;charset=gb2312");Http.send("");html=Encoding.Default.GetString((byte[])Http.responseBody);Http=null;}catch{}returnhtml;}publicboolgetweb(stringstrURL,outstringbuf) { buf=""; try { //Uriurl=newUri(strURL,false); Ht
4、tpWebRequestrequest; request=(HttpWebRequest)WebRequest.Create(strURL); request.Method="POST";//Post请求方式 request.ContentType="text/html;charset=gb2312";//内容类型 stringparaUrlCoded=System.Web.HttpUtility.UrlEncode("");//参数经过URL编码 byte[]payload;
5、 payload=System.Text.Encoding.GetEncoding("GB2312").GetBytes(paraUrlCoded);//将URL编码后的字符串转化为字节 request.ContentLength=payload.Length;//设置请求的ContentLength Streamwriter=request.GetRequestStream();//获得请求流 writer.Write(payload,0,payload.Length);//将请求参数写
6、入流 writer.Close();//关闭请求流 HttpWebResponseresponse; response=(HttpWebResponse)request.GetResponse();//获得响应流 Streams; s=response.GetResponseStream(); StreamReaderobjReader=newStreamReader(s,System.Text.Encoding.GetEncoding("GB2312")); string
7、HTML=""; stringsLine=""; inti=0; while(sLine!=null) { i++; sLine=objReader.ReadLine(); if(sLine!=null) HTML+=sLine; } //HTML=HTML.Replace("<","<"); //HTML=HTML.Replace(">",">"); buf=HTML; returntrue; } catch(Except
8、ionx) { buf=x.Message.ToString(); returnfalse; } } 带Cookie：CookieContainercc=newCookieContainer();publicboolgetweb(stringstrURL,outstringbuf) { buf=""; try { HttpWebRequestrequest; request=(HttpWebRequest)WebReq
