在WinForm中发送HTTP请求的实现方法
如何在WinForm中请求发送HTTP
手工发送HTTP请求主要是调用System.Net的HttpWebResponse方法
手工发送HTTP的GET请求：
stringstrURL="http://localhost/Play/CH1/Service1.asmx/doSearch?keyword=";
strURL+=this.textBox1.Text;
System.Net.HttpWebRequestrequest;
//创建一个HTTP请求
request=(System.Net.HttpWebRequest)WebRequest.Create(strURL);
//request.Method="get";
System.Net.HttpWebResponseresponse;
response=(System.Net.HttpWebResponse)request.GetResponse();
System.IO.Streams;
s=response.GetResponseStream();
XmlTextReaderReader=newXmlTextReader(s);
Reader.MoveToContent();
stringstrValue=Reader.ReadInnerXml();
strValue=strValue.Replace("<","<");
strValue=strValue.Replace(">",">");
MessageBox.Show(strValue);
Reader.Close();
手工发送HTTP的POST请求
stringstrURL="http://localhost/Play/CH1/Service1.asmx/doSearch";
System.Net.HttpWebRequestrequest;
request=(System.Net.HttpWebRequest)WebRequest.Create(strURL);
//Post请求方式
request.Method="POST";
//内容类型
request.ContentType="application/x-www-form-urlencoded";
//参数经过URL编码
stringparaUrlCoded=System.Web.HttpUtility.UrlEncode("keyword");
paraUrlCoded+="="+System.Web.HttpUtility.UrlEncode(this.textBox1.Text);
byte[]payload;
//将URL编码后的字符串转化为字节
payload=System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);
//设置请求的ContentLength
request.ContentLength=payload.Length;
//获得请求流
Streamwriter=request.GetRequestStream();
//将请求参数写入流
writer.Write(payload,0,payload.Length);
//关闭请求流
writer.Close();
System.Net.HttpWebResponseresponse;
//获得响应流
response=(System.Net.HttpWebResponse)request.GetResponse();
System.IO.Streams;
s=response.GetResponseStream();
XmlTextReaderReader=newXmlTextReader(s);
Reader.MoveToContent();
stringstrValue=Reader.ReadInnerXml();
strValue=strValue.Replace("<","<");
strValue=strValue.Replace(">",">");
MessageBox.Show(strValue);
Reader.Close();
