下面的代碼塊是js調(diào)用一般處理程序的代理來實(shí)現(xiàn)js跨域的。如果js需要多次跨域，推薦下面的方法。

代碼如下:
public string GetInfo(HttpContext context)
{
string post = "a=XX&b=XX";
return CreateHttpRequest("https://www.XXXX.com", post, "POST");
}

#region 構(gòu)造請求
/// <summary>
/// 構(gòu)造請求
/// </summary>
/// <param name="requestUrl">請求地址</param>
/// <param name="requestParam">請求參數(shù)</param>
/// <param name="requestMethod">請求方式</param>
/// <returns></returns>
public string CreateHttpRequest(string requestUrl, string requestParam, string requestMethod)
{
try
{
System.Net.HttpWebRequest request = System.Net.HttpWebRequest.Create(requestUrl) as System.Net.HttpWebRequest;
request.Method = requestMethod;
string post = requestParam;

byte[] bytes = System.Text.Encoding.UTF8.GetBytes(post);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes.Length;
System.IO.Stream stream = request.GetRequestStream();
stream.Write(bytes, 0, bytes.Length);
System.Net.HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse;
System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream(), System.Text.Encoding.UTF8);
return sr.ReadToEnd();
}
catch (Exception)
{
return "";
}

}
#endregion
