1.get方法调用接口获取json文件内容

public void GetFunction()
{
    string serviceAddress = "http://222.111.999.444:8687/tttr/usercrd/12/b7e50cb45a?userid=9999";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress);
    request.Method = "GET";
    request.ContentType = "text/html;charset=UTF-8";
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    Stream myResponseStream = response.GetResponseStream();
    StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
    string retString = myStreamReader.ReadToEnd();
    myStreamReader.Close();
    myResponseStream.Close();
    Response.Write(retString);
}

2.post方法调用接口获取json文件内容

public void PostFunction()
{
    string serviceAddress = "http://222.111.999.444:8687/tttr/usercrd/uuu/12/dfd7e4";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress);
    request.Method = "POST";
    request.ContentType = "application/json";
    string strContent = @"{ ""mmmm"": ""89e"",""nnnnnn"": ""0101943"",""kkkkkkk"": ""e8sodijf9""}";
    using (StreamWriter dataStream = new StreamWriter(request.GetRequestStream()))
    {
        dataStream.Write(strContent);
        dataStream.Close();
    }
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    string encoding = response.ContentEncoding;
    if (encoding == null || encoding.Length < 1)
    {
        encoding = "UTF-8"; //默认编码  
    }
    StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
    string retString = reader.ReadToEnd();
    //解析josn
    JObject jo = JObject.Parse(retString);
    Response.Write(jo["message"]["mmmm"].ToString());
}
