Vimeo uploading. Cannot get complete_uri field in response

I've been fiddling quite a bit with my uploading to vimeo.
I've made a ticket request.
I've uploaded the file.
I've checked the file if its uploaded.
I need to run the method DELETE with the complete_uri response i should get from my ticket.
However, im not receiving any complete_URI from the ticket response.
Here is my code:
public static dynamic GenerateTicket()
{
const string apiUrl = "https://api.vimeo.com/me/videos?type=streaming";
var req = (HttpWebRequest)WebRequest.Create(apiUrl);
req.Accept = "application/vnd.vimeo.*+json;version=3.0";
req.Headers.Add(HttpRequestHeader.Authorization, "bearer " + AccessToken);
req.Method = "POST";
var res = (HttpWebResponse)req.GetResponse();
var dataStream = res.GetResponseStream();
var reader = new StreamReader(dataStream);
var result = Json.Decode(reader.ReadToEnd());
return result;
}
This response gives me:
form
ticket_id
upload_link
upload_link_secure
uri
user
In order to finish my upload i need to run step 4 in this guide: https://developer.vimeo.com/api/upload
Sending parameter type=streaming as body:
ASCIIEncoding encoding = new ASCIIEncoding();
string stringData = "type=streaming"; //place body here
byte[] data = encoding.GetBytes(stringData);
req.Method = "PUT";
req.ContentLength = data.Length;
Stream newStream = req.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();

At the moment, type=streaming must be sent in the body of the request, not as a url parameter.
This will probably change to allow either option.

the important point is :
"The first thing you need to do is request upload access for your application. You can do so from your My Apps page."
If you get all values without complete_uri, it means: you dont have an upload access token. So go to your apps and make an upload request

Http Request not sent from android C#

Iam developing a cross platform android app in Xamarin. I want to send a request to register my device. Iam sending my DeviceId, DeviceName and EncodedAccountName i.e my email id.
But I dont get any response. I have tested the request on Postman and get a proper response.
Here is my code:
StringBuilder registerContent = new StringBuilder();
registerContent.Append("DeviceId=").Append(deviceId).Append("&");
registerContent.Append("Name=").Append(deviceName).Append("&");
registerContent.Append("EncodedAccountName‏=").Append(username);
WebRequest request = WebRequest.Create(EndPoints.RegisterDeviceEndPoint);
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = registerContent.ToString();
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();// Dont get any response here
// Display the status.
System.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.
System.Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
return response.ToString();
Any ideas on what might me going wrong?
Thanks

This is how I notify my Web API and wait for a string response:
string myParameters = "?firstParam=" + someParam1 + "&secondParam=" + someParam2;
string url = someHTTPAddress + myParameters;
stringResponseFromWebAPI = (new WebClient()).DownloadString(url);

google api oauth access token retrieval - 400 bad request

I'm trying to retrieve the oauth access token to make calls to some google apis in asp.net mvc, and I wrote the following code for an action:
public ActionResult GetOAuthToken()
{
String url = "https://accounts.google.com/o/oauth2/token";
// Create a request using a URL that can receive a post.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
// Set the Method property of the request to POST.
request.Method = "POST";
request.Host = "accounts.google.com";
// Create POST data and convert it to a byte array.
string postData = String.Format("code={0}&client_id={1}&client_secret={2}&redirect_uri={3}&grant_type=authorization_code", Request.QueryString["code"].ToString(), OAuthConfig.client_id, OAuthConfig.client_secret, OAuthConfig.token_redirect_uri);
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] byteArray = encoding.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();
// SOME CODE TO PROCESS THE RESPONSE
Response.Redirect("/Home");
return View();
}
OAuthConfig is just a class that contains the client id, client secret etc.
I keep getting 'The remote server returned an error: (400) Bad Request.' at the request.GetResponse() line. Where am I going wrong?

Google does provide a higher level library to work with its services, this handles the formatting of the urls and I find it makes it a lot easier to work with their apis. See http://code.google.com/p/google-api-dotnet-client/

HttpWebRequest (post) and redirection

I'm trying to log onto the following website using HttpWebRequest: http://mostanmeldung.moessinger.at/login.php
Texts are in German, but they don't really matter. If you look at the source code (which by the way was not written by me, so don't blame me for its bad style :P), you will see a form tag that contains two input tags. The name of the first one is "BN" (username), and the name of the second one is "PW" (password). I am trying to send data containing values for these two inputs to the webserver using the HttpWebRequest class. However, posting the values redirects the request to another page called "einloggen.php". On that site I am told whether my login was successful.
My problem is that I am able to send the data without any problems, however, all I receive is the content of "login.php", the site you have to enter your username and password on.
This is what my code looks like:
string post = String.Format(PostPattern, Username, Password);
byte[] postBytes = Encoding.ASCII.GetBytes(post);
CookieContainer cookies = new CookieContainer();
// "Address": http://mostanmeldung.moessinger.at/login.php
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Address);
req.CookieContainer = cookies;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = postBytes.Length;
req.AllowAutoRedirect = true;
MessageBox.Show(post); // shows me "BN=boop;PW=hi"
Stream reqStream = req.GetRequestStream();
reqStream.Write(postBytes, 0, postBytes.Length);
reqStream.Close();
WebResponse res;
if (/*req.HaveResponse &&*/ (res = req.GetResponse()) != null)
{
StreamReader reader = new StreamReader(res.GetResponseStream());
MessageBox.Show(reader.ReadToEnd());
return AuthResult.Success;
}
return AuthResult.NoResponse;
The message box at line 22 (5 lines before the end) shows me the content of "login.php" instead of "einloggen.php" which I am redirected to. Why is that?

The ACTION on that form points to einloggen.php, not login.php, so you need to send your POST data to einloggen.php instead.

HTTP POST in .NET doesn't work

I've got a problem with creating an HTTP post request in .NET. When I do this request in ruby it does work.
When doing the request in .NET I get following error:
<h1>FOXISAPI call failed</h1><p><b>Progid is:</b> carejobs.carejobs
<p><b>Method is:</b> importvacature/
<p><b>Parameters are:</b>
<p><b> parameters are:</b> vacature.deelnemernr=478
</b><p><b>GetIDsOfNames failed with err code 80020006: Unknown name.
</b>
Does anyone knows how to fix this?
Ruby:
require 'net/http'
url = URI.parse('http://www.carejobs.be/scripts/foxisapi.dll/carejobs.carejobs.importvacature')
post_args = {
'vacature.deelnemernr' => '478',
}
resp, data = Net::HTTP.post_form(url, post_args)
print resp
print data
C#:
Uri address = new Uri(url);
// Create the web request
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
// Set type to POST
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
// Create the data we want to send
StringBuilder data = new StringBuilder();
data.Append("vacature.deelnemernr=" + HttpUtility.UrlEncode("478"));
// Create a byte array of the data we want to send
byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());
// Set the content length in the request headers
request.ContentLength = byteData.Length;
// Write data
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
// Get the response stream
StreamReader reader = new StreamReader(response.GetResponseStream());
// Console application output
result = reader.ReadToEnd();
}
return result;

Don't you need the ? after the URL in order to do a post with parameters? I think that Ruby hides this behind the scenes.

I found the problem! The url variable in the C# code was "http://www.carejobs.be/scripts/foxisapi.dll/carejobs.carejobs.importvacature/"
It had to be "http://www.carejobs.be/scripts/foxisapi.dll/carejobs.carejobs.importvacature" without the backslash.
