一般初学者可以百度“聚合数据”，上面都有大量的接口和实例可供参考。。

以下是用来调用接口的俩类：

/// <summary>

/// 加载Http请求

/// </summary>

/// <param name="Url"></param>

/// <returns></returns>

public static string HttpGet(string Url)

{

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);

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.GetEncoding("utf-8"));

string retString = myStreamReader.ReadToEnd();

myStreamReader.Close();

myResponseStream.Close();

return retString;

}

/// <summary>

/// 接口调用方法

/// </summary>

/// <param name="Url"></param>

/// <param name="postDataStr"></param>

/// <returns></returns>

public static string HttpGet(string Url, string postDataStr)

{

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr);

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.GetEncoding("utf-8"));

string retString = myStreamReader.ReadToEnd();

myStreamReader.Close();

myResponseStream.Close();

return retString;

}

 

 

下面是接口调用的具体例子，大家可以借鉴一下：

string url = "http://v.juhe.cn/weather/index?cityname=1066&dtype=json&format=1&key=7be8407858533644414e40a2029baccd";

string Json=IService.HttpGet(url);  

object jsons = JsonConvert.SerializeObject(Json);

Console.WriteLine(jsons);

Console.WriteLine("--------------------------------------");

object jsonObj= (JObject)JsonConvert.DeserializeObject(Json);
