We Keep Coding

Why am I not recieving a response from the webrequest?

So i'm trying to learn how WebRequest & WebResponse works.
So far it seems a bit like when you create a TcpClient and listener and make them connect and then send a buffer inbetween them.
However this seems to be a bit different.
So what im doing here is that im making a request to a website, in this case Spotify (Thought I would try to login to spotify as my first project).
Using the POST method to post data to the website.
converting my string to a byteArray
changing the contenttype (Not really sure if im doing it right here, not 100% sure what the values can be)
and the length of the content is the length of the byteArray
I create a stream of data in which I will get the stream from the request.
and then I proceed to write the byteArray starting from the offset of 0 and then the length of the thing that im going to write.
then I close the dataStream.
Now I create a WebResponse (which will get the response to tell me if everything is okay or not (im assuming))
Then I print out the the statusdescription (It doesnt print out anything here not sure why)
Then I create a stream that contains the content from the server
and then I create a streamreader which will read the content..
The rest is pretty straight forward.
Issue
So the issue is that its not printing out anything to the console and I am not sure why. How do I make it print out?
ERROR
So I caught the exception and this is what img etting
"The remote server returned an error: <405> Method not allowed."
CODE
class Program
{
static void Main(string[] args)
{
Console.Title = "Login Test";
Console.ForegroundColor = ConsoleColor.Green;
tester();
Console.ReadLine();
}
private static void tester()
{
try
{
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create("https://accounts.spotify.com/en-SK/login");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "This is a test that posts this string to a Web server.";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
}
catch { }
}
}

How to retrieve the posted data (in byte[] format)?

I have a C# .net web application. I am trying to post a binary data from one application to another using this code
string url = "path to send the data";
string result=null;
string postData = "This is a test that posts this string to a Web server.";
byte[] fileData = Encoding.UTF8.GetBytes (postData);
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create (url);
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
// Set the ContentType property of the WebRequest.
request.ContentType = "multipart/form-data";
// Set the ContentLength property of the WebRequest.
request.ContentLength = fileData.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (fileData, 0, fileData.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
result = ((HttpWebResponse)response).StatusDescription;
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
result = result + responseFromServer;
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close();
By the above code, I am sending byte[] to a second application. How can I retrieve the posted data (in byte[] format) in the second application?

Note: I assume that you are asking about how to retrieve the posted data in second application and also you have access to the code of second application.
Then if it is a webform application then simply on page_load event you can get file name and file itself as:
string strFileName = Request.Files[0].FileName;
HttpPostedFileBase filesToSave = Request.Files[0];
If this is not the requirement, then edit your question and add more details.

EDIT: Updated answer to include both Request and Server side. Server side converts Base64 string to a byte[].
If you're going to post binary data that was read into a byte[], you'll have to convert it to a Base64 string on request side to post it.
Client/Request Side:
byte[] byteData = ReadSomeData();
string postData = Convert.ToBase64String(byteData);
Then on the server side, use the HttpContext to get the InputStream from the Request property. You can then use a StreamReader and its ReadToEnd() method to read in the data. You then convert the posted Base64 string to a byte[].
Something like this:
string postData = string.Empty;
using (StreamReader reader = new StreamReader(context.Request.InputStream))
{
postData = inputStreamReader.ReadToEnd();
}
byte[] data = Convert.FromBase64String(postData);

How to get a response page after submit on csharp?

There is a page in remote web-site, where one can enter input values in forms, click a button and get a result in output form.
I want to send a request to the page with filling necessary input forms, submit it and get a result page with output form filled.
All threads with similar topics give the code samples like this:
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create("http://www.site.com");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = string.Format("inputParam=value");
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
response.Close();
It returns a page with filled input forms, but output field is still blank, like it doesn't do a commit button click.
How can I do a commit from my C# code and receive an html document with output data?

Change the webresponse section to the following;
WebResponse response = request.GetResponse ();
dataStream = response.GetResponseStream ();
StreamReader reader = new StreamReader (dataStream);
string responseFromServer = reader.ReadToEnd ();

How to login to the android market using C#?

I would like to login to the webpage Android Market using C#. I spent the whole day reading about HTTP requests and POST data, but nothing seems to work. What I can do is read the webpage that holds the google login form. But reading the page AFTER the login seems impossible...
Can anyone give me a hint on how to do this?
BTW: The code I've tried is shown below:
string mail = "XXXXXXXXXX#gmail.com";
string pw = "XXXXXXXXXX";
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create (#"https://market.android.com/publish");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = String.Format ("Email={0}&Passwd={1}&signIn=Sign+in", mail, pw);
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();

What I usually do: get live http headers for firefox and you can record the request your browser sends. Then simply repeat that in code.
for example, the android marketplace does it pretty different from your code.
it actually posts to: https://accounts.google.com/ServiceLoginAuth
And posts the data continue=https%3A%2F%2Fmarket.android.com%2Fpublish%2FHome&followup=https%3A%2F%2Fmarket.android.com%2Fpublish%2FHome&service=androiddeveloper&nui=1&dsh=&GALX=&pstMsg=1&dnConn=&timeStmp=&secTok=&Email=Passwd=&signIn=

You need to create a CookieContainer instance and assign it to the CookieContainer property in each request.
This will store the login cookie so that the site knows that you're still logged in.

Making http request from code behind

I am trying to implement Message API
I am not sure how I will be calling this from code-behind and in their snippet it says:
https://platform.3cinteractive.com/api/send_message.php
POST
username=aRDSe3vcaMzh06YrMcxcQw==&password=1BSvQc6lpNlnp4ufWgRLPHNJ7RMrL8CcaWCzL1Vtw+Y=&phone_number=+11234567890&trigger_id=1105&message=howdy

Use the WebRequest class below or use a library like RestSharp for more control or your HTTP request:
// Create a request for the URL.
WebRequest request = WebRequest.Create ("http://www.contoso.com/default.html");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
// Display the status.
Console.WriteLine (response.StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Cleanup the streams and the response.
reader.Close ();
dataStream.Close ();
response.Close ();

You need to use a WebRequest and do an HTTP POST. See this article entitled How to: Send Data Using the WebRequest Class.
