调用微信接口取数据

添加引用：

using System.Web.Script.Serialization;
using System.Collections.Generic;
using Jayrock.Json;

public void GetInfos() {

var code = Request.QueryString["code"];

string json = string.Empty;

string url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=" + appid + "&secret=" + secret + "&code=" + code + "&grant_type=authorization_code";

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

request.Method = "POST";

using (WebResponse response2 = request.GetResponse())

{

using (StreamReader reader = new StreamReader(response2.GetResponseStream(), Encoding.UTF8))

{

//得到url返回的数据

json = reader.ReadToEnd();

}

} //下面可以解析了

if (!string.IsNullOrEmpty(json))

{

//需要添加引用System.Web.Extensions

//然后还要添加using System.Web.Script.Serialization;

JavaScriptSerializer jss = new JavaScriptSerializer();

Dictionary<string, string> dic = jss.Deserialize<Dictionary<string, string>>(json);

string[] js = json.Replace("{", "").Replace("}", "").Split(',');

token = js[0].ToString().Split(':')[1].ToString().Substring(1, js[0].ToString().Split(':')[1].ToString().Length-2);

openid = js[3].ToString().Split(':')[1].ToString().Substring(1, js[3].ToString().Split(':')[1].ToString().Length-2);

}

}
