### POST方式调用接口 ###

/* * 需要引入3个命名空间： * 1、using System.Text * 2、using System.IO * 3、using System.Net */
     // post请求，参数必须
    public static string RestfulLogin(string jsonParam)
    { 
        string url = "http://192.168.xx.xx/auth-web/access/login";
        
        //创建restful的请求
        HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
        request.Method = "post";
        request.ContentType = "application/json";
    
        //创建参数
        string data = jsonParam;
        byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());
        request.ContentLength = byteData.Length;
    
        //以流的形式附加参数
        using (Stream postStream = request.GetRequestStream())
        { 
            postStream.Write(byteData, 0, byteData.Length);
        }
    
        //接收来自restful的回复
        string json = string.Empty;  //返回的类型是json格式字符串，声明一个来接收
        using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
        { 
            //以流的形式读取，返回的就是字符串的json格式
            StreamReader reader = new StreamReader(response.GetResponseStream());
            json = reader.ReadToEnd();
        }
        return json;
    }

### GET方式调用 ###

// Get请求，返回json格式字符串
    // <param name="userCode">用户的账号，手机号</param>
    public static string RestfulLogout(string userCode)
    { 
        string url = "http://192.168.xx.xx/auth-web/access/logout";
        //组合url的get请求
        url += "/" + userCode;
            
        //创建restful的请求
        HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
        request.Method = "get";
        request.ContentType = "application/json";
    
        //接收来自restful的回复
        string json = string.Empty;  //返回的类型是json格式字符串，声明一个来接收
        using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
        { 
            //以流的形式读取，返回的就是字符串的json格式
            StreamReader reader = new StreamReader(response.GetResponseStream());
            json = reader.ReadToEnd();
        }
        return json;
    }
