C # uses GET, POST requests to get results

Transferred from: http://blog.csdn.net/pan_junbiao/article/details/9155497

C # uses GET, POST requests to get results, and here is an example of a simple user login.

1. Get results using GET request

1.1 Creating a Loginhandler.aspx Processing page

protected voidPage_Load (Objectsender, EventArgs e) {    stringresult =""; stringUserName = request.querystring["UserName"]; stringPassword = request.querystring["Password"]; if(UserName = ="Admin"&& Password = ="123") {result="Landing Success"; }    Else{result="Login Failed"; } response.write (Result);}

1.2 Write GET request and get result method

/// <summary>///GET request and get result/// </summary> Public Static stringHttpGet (stringUrlstringpostdatastr) {HttpWebRequest Request= (HttpWebRequest) webrequest.create (Url + (Postdatastr = =""?"":"?") +postdatastr); Request. Method="GET"; Request. ContentType="Text/html;charset=utf-8"; HttpWebResponse Response=(HttpWebResponse) request.    GetResponse (); Stream Myresponsestream=Response.    GetResponseStream (); StreamReader Mystreamreader=NewStreamReader (Myresponsestream, Encoding.UTF8); stringRetString =Mystreamreader.readtoend ();    Mystreamreader.close ();    Myresponsestream.close (); returnretstring;}

1.3 Calling Test

Static void Main (string[] args) {    stringhttp://www.mystudy.cn/LoginHandler.aspx ";     string " username=admin&password=123 " ;     string result = httpget (URL, data);    Console.WriteLine (result);    Console.ReadLine ();}

2. Get results using POST request

2.1 Creating a loginhandler.aspx Processing page

protected voidPage_Load (Objectsender, EventArgs e) {    stringresult =""; stringUserName = request.form["UserName"]; stringPassword = request.form["Password"]; if(UserName = ="Admin"&& Password = ="123") {result="Landing Success"; }    Else{result="Login Failed"; } response.write (Result);}

2.2 Writing Post requests and getting results methods

/// <summary>///POST request and get results/// </summary> Public Static stringHttpPost (stringUrlstringpostdatastr) {HttpWebRequest Request=(HttpWebRequest) webrequest.create (URL); Request. Method="POST"; Request. ContentType="application/x-www-form-urlencoded"; Request. ContentLength=postdatastr.length; StreamWriter writer=NewStreamWriter (Request.    GetRequestStream (), encoding.ascii); Writer.    Write (POSTDATASTR); Writer.    Flush (); HttpWebResponse Response=(HttpWebResponse) request.    GetResponse (); stringencoding =Response.    ContentEncoding; if(Encoding = =NULL|| Encoding. Length <1) {Encoding="UTF-8";//default Encoding} StreamReader Reader=NewStreamReader (response.    GetResponseStream (), encoding.getencoding (Encoding)); stringRetString =Reader.    ReadToEnd (); returnretstring;}

2.3 Calling Test

Static void Main (string[] args) {    stringhttp://www.mystudy.cn/LoginHandler.aspx ";     string " username=admin&password=123 " ;     string result = httppost (URL, data);    Console.WriteLine (result);    Console.ReadLine ();}
