話不多說,直接上代碼吧:
string client_id = "分配的APP ID";
string appid = " 分配的 APP KEY";
string Return_url = "返回處理的url";
public string Authorize()
{
string state = new Random(100000).Next(99, 99999).ToString();//隨機數
HttpHelper http = new HttpHelper();
string url = string.Format("https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id={0}&redirect_uri={1}&state={2}", client_id, Return_url, state);
string str="<script> location.href='" + url + "'</script>";
return str;
}
點擊事件直接調用Authorize()就可以了,我是直接用跳轉鏈接處理的。
protected void Page_Load(object sender, EventArgs e)
{
QQ_Login q = new QQ_Login();
string url = q.Authorize();//這裡調用
Response.Write(url);
}
效果:

點擊圖像,接著在,回調的url裡面調用下面的方法,參數再往下看一點;
public User_info Back_User(string code)
{
string state = new Random(100000).Next(99, 99999).ToString();//隨機數
User_info ui = new User_info();
string url = string.Format("https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&client_id={0}&client_secret={1}&code={2}&redirect_uri={3}&state={4}", client_id, appid, code, Return_url, state);
string uu = HttpHelper.HtmlFromUrlGet(url);//處理http請求幫助類
string code1 = uu.Split('&')[0].Split('=')[1].ToString();//獲得access_token
//根基access_token獲取用戶唯一OpenID
string url_me = string.Format("https://graph.qq.com/oauth2.0/me?access_token={0}" , code1);
string callback = HttpHelper.HtmlFromUrlGet(url_me);//這裡獲取的
callback = callback.Substring(callback.IndexOf('(') + 1, (callback.IndexOf(')') - callback.IndexOf('(') - 1)).Trim();
// dynamic jsonP = JValue.FromObject(callback); //這裡我用的是一個序列化類庫 Newtonsoft.Json.dll 6.0.4版本無奈公司版本過低 只能用4.0的版本 建議使用6.0.4版本
a jsonP = JsonConvert.DeserializeObject<a>(callback);//Newtonsoft.Json.dll 4.0或4.5版本
string OpenID = jsonP.openid;//獲取用戶唯一的OpenID
//根據OpenID獲取用戶信息 可以顯示更多 用的就幾個 需要的可以自己在下面加
string getinfo = string.Format("https://graph.qq.com/user/get_user_info?access_token={0}&oauth_consumer_key={1}&openid={2}", code1, client_id, OpenID);
string user = HttpHelper.HtmlFromUrlGet(getinfo);
b info = JsonConvert.DeserializeObject<b>(user);
ui.Name = info.nickname;
ui.OpenID = OpenID;
ui.img_qq100 = info.figureurl_qq_1;
ui.img_qq50 = info.figureurl_qq_2;
ui.city = info.city;
ui.year = info.year;
ui.Type = 1;
return ui;
}
點擊圖像時跳轉到指定的回調地址,並在redirect_uri地址後帶上Authorization Code;
User_info ui = new User_info();
var verifier = Request.Params["code"]; //獲取Authorization Code
ui = q.Back_User(verifier); 掉用方法並返回數據
再把返回的類貼出來吧
public class User_info
{
public string OpenID { get; set; }//用戶唯一appid
public string Name { get; set; }
public string img_qq50 { get; set; } //QQ圖像40*40
public string img_qq100 { get; set; }
public string city { get; set; }
public int year { get; set; }
}
public class a {
public string client_id { get; set; }
public string openid { get; set; }
}
總結
基本就完了,代碼就這麼多了,感興趣的同學自己動手操作操作才能更加熟悉,希望本文對大家能有所幫助。
