.NET通过调用接口来获取数据的方法

调用方式： string strCount = HttpAnalyzeFunctions.httpGetStr(url);

注：url组成有时需要传入参数，即url+ “参数”。

方法：

    /// <summary>
    /// 发起一个HTTP请求（以GET方式）
    /// </summary>
    /// <param name="url"></param>
    /// <returns></returns>
    public static string httpGetStr(string url)
    {
        WebRequest myWebRequest = WebRequest.Create(url);
        WebResponse myWebResponse = myWebRequest.GetResponse();
        Stream ReceiveStream = myWebResponse.GetResponseStream();
        string responseStr = "";
        if (ReceiveStream != null) {
            StreamReader reader = new StreamReader(ReceiveStream, Encoding.UTF8);
            responseStr = reader.ReadToEnd();
            reader.Close();
        }
        myWebResponse.Close();
        return responseStr;
    }
