话不多说,直接上代码吧:
string client_id = "分配的APP ID"; string appid = " 分配的 APP KEY"; string Return_url = "返回处理的url"; public string Authorize() { string state = new Random(100000).Next(99, 99999).ToString();//随机数 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; }
点击事件直接调用Authorize()
就可以了,我是直接用跳转链接处理的。
protected void Page_Load(object sender, EventArgs e) { QQ_Login q = new QQ_Login(); string url = q.Authorize();//这里调用 Response.Write(url); }
效果:
点击图像,接着在,回调的url
里面调用下面的方法,参数再往下看一点;
public User_info Back_User(string code) { string state = new Random(100000).Next(99, 99999).ToString();//随机数 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);//处理http请求帮助类 string code1 = uu.Split('&')[0].Split('=')[1].ToString();//获得access_token //根基access_token获取用户唯一OpenID string url_me = string.Format("https://graph.qq.com/oauth2.0/me?access_token={0}" , code1); string callback = HttpHelper.HtmlFromUrlGet(url_me);//这里获取的 callback = callback.Substring(callback.IndexOf('(') + 1, (callback.IndexOf(')') - callback.IndexOf('(') - 1)).Trim(); // dynamic jsonP = JValue.FromObject(callback); //这里我用的是一个序列化类库 Newtonsoft.Json.dll 6.0.4版本无奈公司版本过低 只能用4.0的版本 建议使用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;//获取用户唯一的OpenID //根据OpenID获取用户信息 可以显示更多 用的就几个 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; }
点击图像时跳转到指定的回调地址,并在redirect_uri
地址后带上Authorization Code
;
User_info ui = new User_info(); var verifier = Request.Params["code"]; //获取Authorization Code ui = q.Back_User(verifier); 掉用方法并返回数据
再把返回的类贴出来吧
public class User_info { public string OpenID { get; set; }//用户唯一appid public string Name { get; set; } public string img_qq50 { get; set; } //QQ图像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; } }
总结
基本就完了,代码就这么多了,感兴趣的同学自己动手操作操作才能更加熟悉,希望本文对大家能有所帮助。
