I have a web service in my QA box that accepts and process an XML string, send an email and then returns another XML string. To test it, I want to overload it by making a console app to call it by sending it an XML, making make a loop in the console app so it sends it 1,000 times in one shoot. I seen a lot of sample in the internet but I can't get them to work.
This is what I have:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Xml.Linq;
namespace WSStressTest
{
class Program
{
static void Main()
{
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "<?xml version='1.0'?><ROOT><SOMETHING></SOMETHING></ROOT>";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://url:1111/WebService.asmx/ProcessWebService");
request.Method = "POST";
byte[] data = encoding.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(data, 0, data.Length);
dataStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
reader.Close();
dataStream.Close();
response.Close();
//Console.ReadLine();
}
}
}
I always get an 500 error in HttpWebResponse. Now, looking at the code the only thing I can think that is missing is the name of the parameter for POST. What I mean, if I make a form
<form method="post" action="http://url:1111/WebService.asmx/ProcessWebService">
<input type="text" name="sXML" /> <input type="submit" value="submit" />
</form>
placing the xml in the input and submit will work. But I'm naming the data post to the web service sXML. How do I name the xml post in the console app sXML? Is that what I'm missing or is there another error in my code?
Additional question: What would be the best way to get this to run 1,000 times. I was thinking of putting the call inside a while <1000. Is there a better way for it?
Thanks!

I want to send some binary data from my WinForms c# application.
The server expects the data will be sent using POST request. I need to send several files and parameters, something like this:
file1=<binary data>
file2=<binary data>
desc1=<string>
desc2=<string>
I've searched that in Internet and MSDN and the code bellow is the most popular:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://example.com");
webRequest.Method = "POST";
webRequest.ContentType = "multipart/form-data";
webRequest.ContentLength = data.Length;
using (Stream postStream = webRequest.GetRequestStream())
{
postStream.Write(data, 0, data.Length);
postStream.Close();
}
But I don't understand how to use this code to send several parameters? How can I set name for each of them?
Using GET I whould do &file=...&file2=...&desc1=...&desc2=... but using POST I have no clue what to do.
I am looking for a sample code to send request to a web service( SOAP) using C# .net
Get the response back and then validate the response automatically
Ex:http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit
Send celcius data to this web service and get some response back and then validate this response with expected values.
I am looking to do this programmatically using C# nunit framework
Does anyone have idea how to achieve this?
There should be no logic worth testing in the web service itself.
You cannot easily test the web service call, and nor should you. This is the responsibility of the Framework.
Your web service should be a wrapper around the class that does the real work. You would then unit test the class with the logic in, not the web service.
In your example, you should have a class who's responsibility it is to convert Fahrenheit to Celsius. The public method that does this would be covered by your unit tests.
The end point you call to actually perform the conversion (for example, the methods in your .asmx file) would simply call the code above.
using System;
using System.IO;
using System.Net;
using System.Text;
using System.Xml;
using NUnit.Framework;
namespace Examples.System.Net
{
public class WebRequestPostExample
{
public static void Main()
{
String b = "OK";
// Create a request using a URL that can receive a post.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("your end point here");
request.Headers.Add ("SOAPAction", "some soap action here");
request.ContentType = "text/xml;charset=\"utf-8\"";
request.Accept = "text/xml";
request.Method = "POST";
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = #"<s:Envelope xmlns:s="Som request that you want to send";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteArray.Length;
Stream stream = request.GetRequestStream();
stream.Write(byteArray, 0, byteArray.Length);
int a = 0;
stream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Assert.AreEqual(response.StatusCode, b, "Pass");
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
Please assist with the code below.
When I use it on a Pc that doesn't require a proxy and the proxy settings are commented out it works fine but now I have to run the program on a proxy enabled network but it continuously gives me the error:
An unhandled exception of type 'System.Net.WebException' occurred in
System.dll Additional information: The remote server returned an
error: (407) Proxy Authentication Required.
Please note if you try to run the program it wont be able to fetch the data as it needs to be run from a PC whose IP is on the white lists.

Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.

Make sure your proxy details are correct and provide the credentials to the WebProxy object
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlDemo);
request.Credentials = new NetworkCredential("matt.luck", "Mambo88e","JOC");
WebProxy aProxy = new WebProxy();
aProxy.Address = new Uri("Http://182.155.1.205:8080",true)
aProxy.Credentials = new NetworkCredential("matt.luck", "Mambo88e","JOC");
I'm developing the client-side of a third party webservice. The purpose is that I send xml-file to the server.
How should I attach the xml-file to the httpwebrequest? What contentType is needed? More suggestions?
I cannot use mtom or dime.ie because I am using httpwebrequest. I am unable to use WCF either.
Here is a very basic method of sending XML structured data using HttpWebRequest (by the way you need to use request.ContentType = "application/xml";) :
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(myUrl));
request.Method = "POST";
request.ContentType = "application/xml";
request.Accept = "application/xml";
XElement redmineRequestXML =
new XElement("issue",
new XElement("project_id", 17)
);
byte[] bytes = Encoding.UTF8.GetBytes(redmineRequestXML.ToString());
request.ContentLength = bytes.Length;
using (Stream putStream = request.GetRequestStream())
{
putStream.Write(bytes, 0, bytes.Length);
}
// Log the response from Redmine RESTful service
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
Logger.Info("Response from Redmine Issue Tracker: " + reader.ReadToEnd());
}
I use this at one of my projects (NBug) to submit an issue report to my Redmine issue tracker which accepts XML structured data over web requests (via POST). If you need further examples, you can get a couple of fully featured examples here: http://nbug.codeplex.com/SourceControl/list/changesets (click 'Browse' under 'Latest Verion' label on the right then navigate to "NBug\Submit\Tracker\Redmine.cs")
I'd like to download some data from a forum. The page containing the data is visible only to registered users. Here's an example webpage containing user data;
http://www.bikeforums.net/member.php/227664-StackOverflow
I'd like to get the data using wget or C#. I tried logging in via Firefox, then passing the cookies file (hopefully containing the login information) to wget. That was more of a makeshift hack and not a real solution, but it still failed. How do I do this properly?
I set up an account for testing if that's helpful.

Using firebug you can easily get the POST data for the login page and use it to create a WebRequest and Login to the Forum.
The Server create the cookies for authentication and we can use this cookies in the next request on the forum page so the server can authenticate the request and return all the data.
Here I've tested a simple console application that achieves this mechanism.
