HttpWebRequest virtual button click
10,831
I've tried this in LINQPad and it worked:
void Main()
{
var request = (HttpWebRequest)WebRequest.Create("http://128.75.49.209/response.php");
request.Method = WebRequestMethods.Http.Post;
request.ContentType = "application/x-www-form-urlencoded";
using (var stream = request.GetRequestStream())
{
var buffer = Encoding.UTF8.GetBytes("name=asd&pass=asd&country=82&btn=Submit+Query");
stream.Write(buffer,0,buffer.Length);
}
var response = (HttpWebResponse)request.GetResponse();
string result = String.Empty;
using (var reader = new StreamReader( response.GetResponseStream()))
{
result = reader.ReadToEnd();
}
Console.WriteLine(result);
}
The problem is that you used request.php
instead of response.php
in your code.

I have my html-php web page with form, inputs and sumbit button. With html request I\m trying to fill some fields and press a button, but I can't. Here is C# code:
public static string PostData(string data) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost/request.php"); //http://businesslist.com/search/clients/?m=userspace&d=addclassified request.Method = "POST"; request.AllowAutoRedirect = true; request.ContentType = "application/x-www-form-urlencoded"; byte[] EncodedPostParams = Encoding.UTF8.GetBytes(data); request.ContentLength = EncodedPostParams.Length; request.GetRequestStream().Write(EncodedPostParams, 0, EncodedPostParams.Length); request.GetRequestStream().Close(); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); string str = new StreamReader(response.GetResponseStream(), Encoding.UTF8).ReadToEnd(); return str; } static void Main(string[] args) { string data = PostData("name=" + HttpUtility.UrlEncode("lol") + "&btn=Clicked"); Console.WriteLine(data); Console.ReadLine(); }
and 2 php files: request.php
<html> <head> <title>HTTP Request</title> </head> <body> <form action ="http://localhost/response.php" method ="POST"> <input type="text" name="name"> <input type="password" name="pass"> <select name="country"> <option value="-1" selected="selected">Select State/Country</option> <option value="82">Select 1</option> <option value="83">Select 2</option> </select> <input type="submit" name="btn"> </form> </body> </html>
response.php
<?php $data = $_POST["name"]; echo $data; ?>
Here is link to my site
So, how I can press this button?
