关于APP开发第三方登录access_token与openid后台处理

1.流程：

App端调用第三方进行登录

->

第三方返回openid(微博叫uid)与access_token

->

App端发送openid与access_token到后台

->

后台调用第三方提供的校验API进行校验

->

校验成功返回本应用的访问令牌token

2.后台数据库只需要在用户表保存openid即可

3.具体校验过程：

后台采用Java开发   使用Jfinal框架 HttpKit和StrKit都是jfinal框架的内容   StrKit.isBlank方法是字符串的非空验证 

微博：

url(post)	https://api.weibo.com/oauth2/get_token_info
参数	access_token
返回值	{     "uid": 6021880,     "appkey": "9187121",     "scope": "follow_app_official_microblog",     "create_at": 15231756,     "expire_in": 5667 }
做法：	比对返回的uid与open_id是否一致

具体代码如下：

public static boolean checkWeibo(String token, String openId) {
		String url = "https://api.weibo.com/oauth2/get_token_info";
		Map<String, String> paras = new HashMap<String, String>();
		paras.put("access_token", token);
		String responseString = HttpKit.post(url, paras, null);
		if (JFinal.me().getConstants().getDevMode()) {
			System.out.println(responseString);
		}
		if (StrKit.isBlank(responseString)) {
			return false;
		}
		JSONObject object = JSON.parseObject(responseString);
		if (object == null) {
			return false;
		}
		String uid = object.getString("uid");
		if (StrKit.isBlank(uid) || !uid.equals(openId)) {
			return false;
		}
		return true;
	}
           

微信：

url(get)	https://api.weixin.qq.com/sns/auth
参数	access_token,openid
返回值	{"errcode":0,"errmsg":"ok"}
做法	errcode=0代表成功

具体代码如下：

public static boolean checkWechat(String token, String openId) {
		String url = "https://api.weixin.qq.com/sns/auth";
		Map<String, String> paras = new HashMap<String, String>();
		paras.put("access_token", token);
		paras.put("openid", openId);
		String responseString = HttpKit.get(url, paras);
		if (JFinal.me().getConstants().getDevMode()) {
			System.out.println(responseString);
		}
		if (StrKit.isBlank(responseString)) {
			return false;
		}
		JSONObject object = JSON.parseObject(responseString);
		if (object == null) {
			return false;
		}
		int errcode = object.getIntValue("errcode");
		if (errcode != 0) {
			return false;
		}
		return true;
	}
           

QQ：

url(get)	https://graph.qq.com/user/get_user_info
参数	oauth_consumer_key,access_token,openid
返回值	{     "ret": 0,     "msg": "",     "is_lost":0,     "nickname": "123",     "gender": "男",     "province": "陕西",     "city": "西安",     "year": "",     "is_yellow_vip": "0",     "vip": "0",     "yellow_vip_level": "0",     "level": "0",     "is_yellow_year_vip": "0" }
做法	只需要比对ret是否为0

具体代码：

public static boolean checkQQ(String token, String openId) {
		String url = "https://graph.qq.com/user/get_user_info";
		Map<String, String> paras = new HashMap<String, String>();
		paras.put("oauth_consumer_key", "1106812746");//App在腾讯开放平台注册的 appid
		paras.put("access_token", token);
		paras.put("openid", openId);
		String responseString = HttpKit.get(url, paras);
		if (JFinal.me().getConstants().getDevMode()) {
			System.out.println(responseString);
		}
		if (StrKit.isBlank(responseString)) {
			return false;
		}
		JSONObject object = JSON.parseObject(responseString);
		if (object == null) {
			return false;
		}
		int ret = object.getIntValue("ret");
		if (ret != 0) {
			return false;
		}
		return true;
	}
           

第一次做，各路大神轻喷。
