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

Foursquare checking using API

I am trying to checkin to Foursquare using the API, I have obtained the oauth_token and am doing a POST request with the oauth_token. According to the documentation the endpoint I'm hitting is https://api.foursquare.com/v2/checkins/add. This however returns a 400 Bad Request message. This is my code in C#
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.foursquare.com/v2/checkins/add?oauth_token"+ oauth_token + "&venueId=" + venueId);
request.Method = "POST";
HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();
Stream responseStream = webResponse.GetResponseStream();
When I do the same in curl however, it posts a checkin and I get a json response back
curl --data "oauth_token=[oaut_token]&venueId=[venueId]" https://api.foursquare.com/v2/checkins/add

Ultimately what worked is the following:
using (WebClient wc = new WebClient())
{
System.Collections.Specialized.NameValueCollection reqparm = new System.Collections.Specialized.NameValueCollection();
reqparm.Add("oauth_token", oauth_token);
reqparm.Add("venueId", venueId);
byte[] responsebytes = wc.UploadValues(URI, "POST", reqparm);
string responsebody = Encoding.UTF8.GetString(responsebytes);
}
Thanks everyone for your help!

You should write your data to request input stream: HttpWebRequest.GetRequestStream()

C# HttpWebRequest POST => !! Unexpected error while processing request: invalid %-encoding

i am facing a problem where i try to communicate with a Ruby API from a C# application.
I need to POST some JSON data, with the parameter name "data" but the API return me: '!! Unexpected error while processing request: invalid %-encoding'.
I tried with Content-Type set to 'application/json' and 'application/x-www-form-urlencoded; charset=utf-8'.
My POST data look like this 'data=some_json_string'.
I figure i should escape the json string, so if it is my problem, how to do it with .NET without using a 3rd party library?
Code:
byte[] data = System.Text.ASCIIEncoding.UTF8.GetBytes(sdata);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url, UriKind.Absolute));
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded; charset=utf-8";
request.ContentLength = data.Length;
Stream reqStream = request.GetRequestStream();
// Send the data.
reqStream.Write(data, 0, data.Length);
reqStream.Close();
Thanks in advance!

Presuming the string sdata coming in is already in JSON format you could do:
using (WebClient wc = new WebClient())
{
string uri = "http://www.somewhere.com/somemethod";
string parameters = "data=" + Uri.EscapeDataString(sdata);
wc.Headers["Content-type"] = "application/x-www-form-urlencoded";
string result = wc.UploadString(uri, parameters);
}
Depending on the consuming service it may need the Content-type set to application/json?

Unable to retrieve message body on server-side from HTTP Post

I am sending an HTTP post request using HTTPWebRequest to an URL. I am sending the post data using multipart/form-data content type along with the content length of the body. However, on the server side, I am unable to retrieve the body. I can only see the headers sent. The content length of the body I sent also matches.
Why am I not able to retrieve the body.
The request method looks like this:
public void Reset(string originalFileData, string uploadLocation)
{
TcpClient client = new TcpClient();
IPEndPoint serverEndPoint = new IPEndPoint(IPAddress.Parse(Server), portNo);
client.Connect(serverEndPoint);
string responseContent;
string serverUrl = "http://" + Server + ":" + portNo + "/abc.aspx" + "?uplvar=" + uploadLocation;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serverUrl);
request.ContentType = "multipart/form-data";
request.Method = "POST";
request.ServicePoint.Expect100Continue = false;
string postData = originalFileData;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteArray.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
response.Close();
}
Edit: I forgot to mention, I am able to retrieve the body on the first time I send the request, but on any subsequent requests I send, I am not able to retrieve it. I am creating a new connection each time I send a request. So, something might be preventing the request body from being retrieved. I am not sure why.

Try replacing
request.ContentType = "multipart/form-data";
with
request.ContentType = "application/x-www-form-urlencoded";
or check this SO answer for code which works with multipart/formdata.

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.
