Hi guys,
I would be very grateful if someone could give me an indication of how to build
up the request to the API. Just for a simple page query. I have some code that
uses Web request/response which works with other API's but it does not work
with the mediawiki api. I would be verya grateful if anyone could help me out.
I one of the methods I have tried below:
I consistenly get a "The remote server returned an error: (417) Expectation
failed." Error.
string pgTitle = txtPageTitle.Text;
Uri address = new Uri("http://en.wikipedia.org/w/api.php";);
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
string action = "query";
string query = pgTitle;
StringBuilder data = new StringBuilder();
data.Append("action=" + HttpUtility.UrlEncode(action));
data.Append("&query=" + HttpUtility.UrlEncode(query));
byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());
request.ContentLength = byteData.Length;
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}
using (HttpWebResponse response = request.GetResponse() as
HttpWebResponse)
{
// Get the response stream
StreamReader reader = new
StreamReader(response.GetResponseStream());
divWikiData.InnerText = reader.ReadToEnd();
}
