C#版

提供者：成都谊诚，王小蓉

using System.Net;

/// <summary>

/// 这个是用POST方法发送HTTP请求的C#代码，一种通用方法，你要用这个函数把你的数据发出去

/// </summary>

/// <param name="url">即Post Url</param>

/// <param name="postString">即Post数据</param>

/// <returns>即返回</returns>

public static string PostData(string url, string postString) {

    byte[] postData = Encoding.UTF8.GetBytes(postString);
    WebClient webClient = new WebClient();
    webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
    byte[] resoponseData = webClient.UploadData(url, "POST", postData);
    return Encoding.UTF8.GetString(resoponseData);

}

VB版

需引用Microsoft XML,v3.0

Public Function PostData(ByVal sUrl As String, ByVal sData As String) As String

    Dim oxh As New MSXML2.XMLHTTP

    oxh.Open "post", sUrl, False    'False-同步；True-异步

    oxh.setRequestHeader "CONTENT-TYPE", "application/x-www-form-urlencoded;charset=UTF-8"

    oxh.send sData

    If oxh.readyState = 4 Then

        If oxh.Status = 200 Then PostData = oxh.responseText

    End If

    Set oxh = Nothing

End Function
