假设有两个公众号A和B, 怎样在B公众号的项目里面判断用户时候关注了A公众号,
1.需要将两个公众号绑定在同一个微信开放平台下面, 同一个开放平台会给用户统一的unionid, 而不同的公众号openid不同,
这时unionid就是连接两个不同公众号相同粉丝的唯一纽带
2.登录B项目的时候授权A的微信
Controller部分/*** B调用A部分*///微信浏览器，用户自动登录,并重新定向 附带code参数// back_url 经过urlencode的回跳地址public function get_user_code(){$back_url = I("redirect_uri","","urldecode");$password = I("password","","trim");$WxUsersModel = D('WxUsers');$result = $WxUsersModel->getCode($back_url,$password);if(isset($result['code']) && isset($result['lexer'])){$url = $result['lexer'];$url_replace=preg_replace('/(.*)(?|&)code=[^&]+?(&)(.*)/i','$1$2$4',$url.'&');$url_substr=substr($url_replace,0,-1);if(strpos($url_substr,'?') === false){$redirect_url = $url_substr.'?code='.$result['code'];} else {$redirect_url = $url_substr.'&code='.$result['code'];}redirect($redirect_url);}}
Model部分//餐饮圈用户登录public function getCode($state = 'STATE',$password = '') {if ($_REQUEST['code']) {$code = $_REQUEST['code'];$lexer = $_REQUEST['state'];$user_info_json = https_request("https://api./sns/oauth2/access_token?appid=".C('WX_APPID')."&secret=".C('WX_APPSECRET')."&code=".$code."&grant_type=authorization_code");$user_info = json_decode($user_info_json,true);$user_info_json11 = https_request("https://api./sns/userinfo?access_token=".$user_info['access_token']."&openid=".$user_info['openid']."&lang=zh_CN ");$data = json_decode($user_info_json11,true);//是否已经关注$is_subscribe = $this->checkSubscribe($data['openid']);$wx_data['is_subscribe'] = $is_subscribe==1?$is_subscribe:0;//查询wx_users是否有记录,记录在用户表中$exist = $this->getByUnionID($data['unionid']);S($code,$data,3000);if(empty($exist)){$wx_data['sex'] = $data['sex'];$wx_data['city'] = $data['city'];$wx_data['province'] = $data['province'];$wx_data['country'] = $data['country'];$wx_data['unionid'] = $data['unionid'];$wx_data['openid'] = $data['openid'];$wx_data['nickname'] = $data['nickname'];$wx_data['headimgurl'] = $data['headimgurl'];//添加用户信息$this->addWeixin($wx_data);} else {//用户存在，修改用户$wx_data['id'] = $exist['id'];if(!empty($exist['nickname']) && !empty($exist['headimgurl']) ) {if(strpos($exist['headimgurl'], 'http://') !== 0 || strpos($exist['headimgurl'], 'https://') !== 0){unset($data['nickname']);unset($data['headimgurl']);}}//更新用户信息$this->upObj($wx_data);}$return['code'] = $code;$return['lexer'] = base_decodes($lexer);return $return;} else {if($password != C('WX_PWD')){exit("Password error");}$back_url = "/phone/Api/get_user_code";header("Location: https://open./connect/oauth2/authorize?appid=".C('WX_APPID')."&redirect_uri=". urlencode($back_url)."&response_type=code&scope=snsapi_userinfo&state=".base_encodes($state)."#wechat_redirect" );exit;}}
通过这样的操作, 登录B公众号项目的时候先使用A授权, 因为推广的是A公众号,所以需要给用户发送额模版消息应该使用A公众号的openid等信息, 而其他的业务操作需要在B公众号进行, 因此在项目中需要B公众号信息的地方再用B公众号授权一次, 这种做法实属无奈之举, 但是业务就这样没办法...
A项目的用户表记录微信信息后, 通过业务上的相关操作,将用户信息存入B项目的用户表中,此时必须要存用户的unionid, 这是不同工种号关联用户的唯一纽带
/*** 用户登录* User/login_option* @param user_name 手机号* @param password 密码* @param code 验证码* .01.17* BY HF*/public function login_option(){config('default_return_type','json');$param=$this->request->param();$result = $this->validate($param,'User.login');if(true !== $result){// 验证失败 输出错误信息return ['code'=>400,'message'=>$result];}$code_info=Db::name('code_info')->where(['mobile'=>$param['user_name']])->order('code_info_id desc')->find();if($code_info){if(time() - $code_info['time'] > 60 * 20){Db::name('code_info')->delete($code_info['code_info_id']);return ['code'=>400,'message'=>'验证码已失效，请重新发送'];}else {if ($code_info['code'] != $param['code']) {return ['code' => 400, 'message' => '验证码输入错误'];}}}else{return ['code'=>400,'message'=>'未发送验证码'];}unset($param['code']);$info=Db::name('users')->where(['user_name'=>$param['user_name']])->find();if($info){ //用户存在，登录$token = authcode($info['user_id'],"ENCODE", config('api.api_key'));$data=['token'=>$token,'user_id'=>$info['user_id'],'nickname'=>$info['nickname'],'user_name'=>$info['user_name']];$userModel = new Users();$userModel->where(['user_name'=>$param['user_name']])->data(['last_time'=>date('Y-m-d H:i:s'),'last_ip'=>request()->ip()])->update();$return=array_merge(['code'=>200,'message'=>'登录成功'],$data);return $return;}else{//param参数应该包含unionid$userModel = new Users();$param['credit_line'] = 5;$param['reg_step'] = 2;//是客户经理推荐的填写客户经理的信息if(isset($param['referrer_id']) && !empty($param['referrer_id'])&& $param['referrer_id']!='null'){//客户经理信息$salesman = $userModel->getSalesman($param['referrer_id']);$param['referrer_name'] = $salesman['name'];} else {$param['referrer_name'] = 0;$param['referrer_id'] = 0;}Log::log('login:date:'.date('Y-m-d H:i:s',time()).'&login_data='.var_export($param, true));//使用集采平台授权授权注册,不记录集采平台的openidunset($param['openid']);$userModel->data($param)->save();$id = $userModel->user_id;//记录积分Db::name('credit')->insert(['user_id'=>$id,'item'=>'user_name','value'=>5,'create_time'=>date('Y-m-d H:i:s')]);$token = authcode($id,"ENCODE", config('api.api_key'));$data=['token'=>$token,'user_id'=>$id,];$return = array_merge(['code'=>200,'message'=>'登录成功'],$data);return $return;}}
以上是我项目中给B项目技术数据的方式
3. 项目操作中需要B公众号授权的
Controller//微信浏览器，用户自动登录,并重新定向 附带code参数// back_url 经过urlencode的回跳地址public function get_user_code(){$back_url = input("redirect_uri","","urldecode");$password = input("password","","trim");$WxUsersModel = model('Wechat');$result = $WxUsersModel->getUserInfo($back_url,$password);if(isset($result['code']) && isset($result['lexer'])){$url = $result['lexer'];$url_replace=preg_replace('/(.*)(?|&)code=[^&]+?(&)(.*)/i','$1$2$4',$url.'&');$url_substr=substr($url_replace,0,-1);if(strpos($url_substr,'?') === false){$redirect_url = $url_substr.'?code='.$result['code'];} else {$redirect_url = $url_substr.'&code='.$result['code'];}return redirect($redirect_url);}}
Model//获取用户详细信息//$lexer 原样返回的数据public function getUserInfo($lexer = 'STATE',$password = "") {if (isset($_REQUEST['code'])) {$code = input('code','','trim');$state = input('state','','trim');$user_access_token_json = https_request("https://api./sns/oauth2/access_token?appid=".$this->appid."&secret=".$this->appsecret."&code=".$code."&grant_type=authorization_code");$user_access_token = json_decode($user_access_token_json,true);$user_info_json = https_request("https://api./sns/userinfo?access_token=".$user_access_token['access_token']."&openid=".$user_access_token['openid']."&lang=zh_CN ");$resuult = json_decode($user_info_json,true);cache($code,$resuult,300);//更新B公众号项目用户表的openidmodel('Users')->save(['openid' => $resuult['openid']], ['unionid' => $resuult['unionid']]);$return['lexer'] = $state == 'STATE' ? "" : base_decodes($state);$return['code'] = $code;return $return;} else {if($password != $this->password){exit("请求密码错误");}$back_url = get_url();header("Location: https://open./connect/oauth2/authorize?appid=".$this->appid."&redirect_uri=". urlencode($back_url)."&response_type=code&scope=snsapi_userinfo&state=".base_encodes($lexer)."#wechat_redirect" );// header("Location: https://open./connect/oauth2/authorize?appid=".$this->appid."&redirect_uri="//. urlencode($back_url)."&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect" );exit;}}
将两边的公众号openid和unionid都记录到数据库,以后就好操作了, 为了避免用户每次操作的时候都感觉不停地微信授权,降低体验感, 应该做一定的判断, B公众号的额openid获取到一次之后就不用在授权了
