Imgur is a image uploading website who offers an API to upload
My code looks exactly like the PHP code they provide as an example. however, in their php code they are http_build_query($pvars);
It seems like they are URLEncoding their query before posting it. edit: Note that I have changed to full .NET 3.5 rather then the client profile. This gave me access to system.web
so I used httputliity.urlencode()
. This made the api return a "fail" with a "no image was sent". If I don't encode then the API returns an "okay" with a link to the picture, however no picture is uploaded (like a blank file).
How can I fix my code to work properly against their API?
Image image = Image.FromFile("C:\Users\Affan\Pictures\1509310.jpg");
MemoryStream ms = new MemoryStream();
// Convert Image to byte[]
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] imageBytes = ms.ToArray();
WebRequest wb = WebRequest.Create(new Uri("http://imgur.com/api/upload.xml"));
wb.ContentType = "application/x-www-form-urlencoded";
wb.Method = "POST";
wb.Timeout = 10000;
Console.WriteLine(imageBytes.Length);
string parameters = "key=433a1bf4743dd8d7845629b95b5ca1b4&image=" + Convert.ToBase64String(imageBytes);
Console.WriteLine("parameters: " + parameters.Length);
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
byte[] bytes = encoding.GetBytes(parameters);
// byte[] bytes = Convert.FromBase64String(parameters);
System.IO.Stream os = null;
try { // send the Post
wb.ContentLength = bytes.Length; //Count bytes to send
os = wb.GetRequestStream();
os.Write(bytes, 0, bytes.Length); //Send it
} catch (WebException ex) {
MessageBox.Show(ex.Message, "HttpPost: Request error");
Console.WriteLine(ex.Message);
} finally {
if (os != null) {
// os.Close();
}
}
try { // get the response
WebResponse webResponse = wb.GetResponse();
StreamReader sr = new StreamReader(webResponse.GetResponseStream());
//MessageBox.Show(sr.ReadToEnd().Trim());
Console.WriteLine(sr.ReadToEnd().Trim());
} catch (WebException ex) {
MessageBox.Show(ex.Message, "HttpPost: Response error");
}
