C#使用GET、POST请求获取结果
C#使用GET、POST请求获取结果，这里以一个简单的用户登陆为例。
1、使用GET请求获取结果
1.1创建LoginHandler.aspx处理页面
protectedvoidPage_Load(objectsender,EventArgse)
{
stringresult="";
stringuserName=Request.QueryString["UserName"];
stringpassword=Request.QueryString["Password"];
if(userName=="admin"&&password=="123")
{
result="登陆成功";
}
else
{
result="登陆失败";
}
Response.Write(result);
}
1.2编写GET请求与获取结果方法
///<summary>
///GET请求与获取结果
///</summary>
publicstaticstringHttpGet(stringUrl,stringpostDataStr)
{
HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(Url+(postDataStr==""?"":"?")+postDataStr);
request.Method="GET";
request.ContentType="text/html;charset=UTF-8";
HttpWebResponseresponse=(HttpWebResponse)request.GetResponse();
StreammyResponseStream=response.GetResponseStream();
StreamReadermyStreamReader=newStreamReader(myResponseStream,Encoding.UTF8);
stringretString=myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
returnretString;
}
1.3调用测试
staticvoidMain(string[]args)
{
stringurl="http://www.mystudy.cn/LoginHandler.aspx";
stringdata="UserName=admin&Password=123";
stringresult=HttpGet(url,data);
Console.WriteLine(result);
Console.ReadLine();
}
2、使用POST请求获取结果
2.1创建LoginHandler.aspx处理页面
protectedvoidPage_Load(objectsender,EventArgse)
{
stringresult="";
stringuserName=Request.Form["UserName"];
stringpassword=Request.Form["Password"];
if(userName=="admin"&&password=="123")
{
result="登陆成功";
}
else
{
result="登陆失败";
}
Response.Write(result);
}
2.2编写POST请求与获取结果方法
///<summary>
///POST请求与获取结果
///</summary>
publicstaticstringHttpPost(stringUrl,stringpostDataStr)
{
HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(Url);
request.Method="POST";
request.ContentType="application/x-www-form-urlencoded";
request.ContentLength=postDataStr.Length;
StreamWriterwriter=newStreamWriter(request.GetRequestStream(),Encoding.ASCII);
writer.Write(postDataStr);
writer.Flush();
HttpWebResponseresponse=(HttpWebResponse)request.GetResponse();
stringencoding=response.ContentEncoding;
if(encoding==null||encoding.Length<1){
encoding="UTF-8";//默认编码
}
StreamReaderreader=newStreamReader(response.GetResponseStream(),Encoding.GetEncoding(encoding));
stringretString=reader.ReadToEnd();
returnretString;
}
2.3调用测试
staticvoidMain(string[]args)
{
stringurl="http://www.mystudy.cn/LoginHandler.aspx";
stringdata="UserName=admin&Password=123";
stringresult=HttpPost(url,data);
Console.WriteLine(result);
Console.ReadLine();
}
