How do you do a Remote HTTP Post (request) in C#?
推荐答案
这是从一个小的应用程序,我写一次发布形式值到URL代码。它应该是相当强劲的。
This is code from a small app I wrote once to post a form with values to a URL. It should be pretty robust.
_formValues是一个字典<字符串,字符串>包含张贴变量及其值
_formValues is a Dictionary<string,string> containing the variables to post and their values.
// encode form data
StringBuilder postString = new StringBuilder();
bool first=true;
foreach (KeyValuePair pair in _formValues)
{
if(first)
first=false;
else
postString.Append("&");
postString.AppendFormat("{0}={1}", pair.Key, System.Web.HttpUtility.UrlEncode(pair.Value));
}
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] postBytes = ascii.GetBytes(postString.ToString());
// set up request object
HttpWebRequest request;
try
{
request = WebRequest.Create(url) as HttpWebRequest;
}
catch (UriFormatException)
{
request = null;
}
if (request == null)
throw new ApplicationException("Invalid URL: " + url);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postBytes.Length;
// add post data to request
Stream postStream = request.GetRequestStream();
postStream.Write(postBytes, 0, postBytes.Length);
postStream.Close();
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
