连接到 Wikipedia API 的 WebRequest

这可能是一个可悲的简单问题，但我似乎无法格式化帖子网络请求/响应以从维基百科API http://en.wikipedia.org/wiki/Wikipedia:API。如果有人可以帮助我查看我的问题，我已在下面发布了我的代码。

    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();
    }

您可能想首先尝试 GET 请求，因为它更简单一些（您只需要 POST 即可登录维基百科）。例如，尝试模拟这个请求：

这是代码：

HttpWebRequest myRequest =
  (HttpWebRequest)WebRequest.Create("http://en.wikipedia.org/w/api.php?action=query&prop=images&titles=Main%20Page");
using (HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse())
{
    string ResponseText;
    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
    {
        ResponseText = reader.ReadToEnd();
    }
}

Edit:他在 POST 请求中遇到的另一个问题是，The exception is : The remote server returned an error: (417) Expectation failed.可以通过设置来解决：

System.Net.ServicePointManager.Expect100Continue = false;

（这是来自：HTTP POST 返回错误：417“预期失败。” https://stackoverflow.com/questions/566437/http-post-returns-the-error-417-expectation-failed-c-resolved)
