我正在尝试使用这种方法将照片发布到 Facebook 墙上。
/// <param name="method">Http Method</param>
/// <param name="url">Full url to the web resource</param>
/// <param name="postData">Data to post in querystring format</param>
/// <returns>The web server response.</returns>
public string WebRequest(Method method, string url, string postData)
{
HttpWebRequest webRequest = null;
StreamWriter requestWriter = null;
string responseData = "";
webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
webRequest.Method = method.ToString();
webRequest.ServicePoint.Expect100Continue = false;
webRequest.UserAgent = "[]";
webRequest.Timeout = 20000;
if (method == Method.POST)
{
webRequest.ContentType = "application/x-www-form-urlencoded";
requestWriter = new StreamWriter(webRequest.GetRequestStream());
try
{
requestWriter.Write(postData);
}
catch
{
throw;
}
finally
{
requestWriter.Close();
requestWriter = null;
}
}
responseData = WebResponseGet(webRequest);
webRequest = null;
return responseData;
}
我遇到的问题是postData。我无法让它工作,我不确定那个字符串会是什么样子?谁能举个例子?
