最近在弄一些第三方的平台，经常调用第三方的接口实现某些特定的功能,那么怎样实现呢？广州网站制作告诉你！

在实现的同时基本上都需要本地的数据经过服务器在Request到第三方的服务器中处理，再返回相应的数据结构体：json/xml

以下是我总结的一个小方法，请农友们笑纳：

public static string PostWebReq(string PostUrl, string ParamData, Encoding DataEncode)
{
string ret = string.Empty;
try
{
byte byteArray = DataEncode.GetBytes(ParamData);
HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(new Uri(PostUrl));
webReq.Method = "POST";
webReq.ContentType = "application/x-www-form-urlencoded";
webReq.ContentLength = byteArray.Length;

Stream newStream = webReq.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);
newStream.Close();

HttpWebResponse response = (HttpWebResponse)webReq.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream(), DataEncode);
ret = sr.ReadToEnd();

sr.Close();
response.Close();
newStream.Close();
}
catch (WebException ex)
{
Log.WriteLog(LogFile.Error, ex.Message);
}
finally
{
Log.WriteLog(LogFile.Info, ret);
}
return ret;
}
