三方登陆的整体思路是获取第三方中的openid,然后与用户关联(存到数据库),进行登陆。本文主要和大家分享网站接入qq,微信,微博第三方登陆详解,希望能帮助到大家。
现在需求是:两个(或多个)一级域名,如maxiye.cn
和yexima.com
,同时每个域名下有多个二级域名分布,如:app.maxiye.cn,new.maxiye.cn,old.maxiye.cn,app.yexima.com,new.yexima.com,old.yexima.com
...等,但是这些域名下使用了同一份代码(对,就是马甲),共享数据库和session。同时旗下每个域名均包含pc,ios,Android端,如何全部接入第三方登陆?
qq,微信,微博接入要点:
1.申请入口:QQ是QQ互联,微信是微信开放平台,微博是微博开放平台;
2.回调域设置:QQ可以设置一级域名且可以有多个,必须http://
开头,;
结束,如http://maxiye.cn;http://yexima.com;
;微信只能设置到二级域名且只能一个,格式为:app.maxiye.cn
;
微博也可以设置一级域名且是一个:maxiye.cn
;
3.unionid获取:多个app(同一开发者账号下
)共享数据库,故需要使用unionid确认身份。QQ获取uuid需要额外申请权限,具体参考相同开发者账号下的不同appid应用如何打通;微信已有unionid获取接口;微博则uid即unionid;
坑:
1.QQ接口返回的结果好多是jsonp格式,需要手动剥离callback()
;
2.微博获取获取access_token竟然必须使用post
,惊了;
3.微信不支持回调地址填写一级域名,所以需要使用统一域名(代理)作为回调地址,然后内部再重定向到发申请的域名;
下边是一个写好的工具类:

使用方法如下:
//第三方登录界面处理 public function actionLoginByOpenid(){ Yii::$app->response->format= Response::FORMAT_HTML; $params = Yii::$app->request->get(); $oauth = new OauthLogin($params); if(empty($params['code'])){ $url = $oauth->getOauthUrl(); return $this->redirect($url); }else{ //微信代理跳转处理 if(isset($params['redirect']) && $params['redirect'] != $oauth->server){ $proxy = $oauth->proxy; $server = $params['redirect']; return $this->redirect(str_replace($proxy, $server, Url::current(['redirect'=>null], 'http'))); } $openid = $oauth->getUuid(); if (!$openid) { //失败处理TODO } else { //成功处理TODO } } }
具体流程(qq为例)如下:
1.用户点击QQ登陆图标,访问链接http://app.maxiye.cn/site/login-by-openid?type=qq
;
2.服务器处理获取QQ的授权链接,重定向;
3.QQ在回调地址中添加code参数(Authorization Code),回调http://app.maxiye.cn/site/login-by-openid?type=qq&state=4a78***&code=1CA8DF***
;
4.服务器根据code参数,验证state,获取access_token,然后获取unionid(uid),处理结果。
