asp.net 后台 get，post請求

//Post請求
public static string Post(string url,string obj=null)
{
string param = (obj);//參數
byte[] bs = Encoding.Default.GetBytes(param);

//創建一個新的HttpWebRequest對象。
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(url);

// 將方法屬性設置為“POST”以將數據發布到URI。
req.Method = "POST";

//設置contentType屬性。
req.ContentType = "application/json";

req.ContentLength = bs.Length;
using (Stream reqStream = req.GetRequestStream())
{
reqStream.Write(bs, 0, bs.Length);

reqStream.Close();
HttpWebResponse response2 = (HttpWebResponse)req.GetResponse();
StreamReader sr2=new StreamReader(response2.GetResponseStream(), Encoding.UTF8);
string text2 = sr2.ReadToEnd();
return text2;
}

}

//Get請求
public static string Get(string func, string strParam = null)
{
string result = "";
StringBuilder realUrl = new StringBuilder();
realUrl.Append(func).Append("?");

if (strParam != null)
