微信公众号登陆、模板发送、access_token获取等PHP代码分享
我现在在项目中遇到要将公众号和小程序联系起来，我们知道，微信公众和小程序在微信开放平台下绑定就可以获得unionid，unionid是否相同就可以 确定用户是否是同一个人，微信小程序开发文档写的很清晰，要想了解详情就点这里（点击打开链接）；小程序模板消息我们知道，发送需要formid或者prepay_id,但是formid或者prepay_id是有时间限制，7天，为了弥补这个缺陷，我就想用微信公众号来发送模板消息，因此我就写了这些功能代码，我主要分享一下，公众号登陆，和模板消息TP3.2代码；
代码如下：
public function _initialize(){ if(!isset($_SESSION["user_id"])||empty($_SESSION["user_id"])){ //没有登录 // 去登录； $this->login(); } } //用户登录 public function login(){ $shop_id=18;//店铺id $roe=M('wx_gzh_config')->field('appid,appsecret')->where('shop_id='.$shop_id)->find(); $kf_appid=$roe['appid']; $kf_secret=$roe['appsecret']; //网页授权 $code=$_GET['code']?$_GET['code']:""; if(empty($code)){ $urlt="https://open.weixin.qq.com/connect/oauth2/authorize?appid=".$kf_appid."&redirect_uri=".urlEncode('http://gw.kxsp.net/Home/GZHao/login')."&response_type=code&scope=snsapi_userinfo&state=12345#wechat_redirect"; header("location:".$urlt);return; // break; }else{ $url="https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$kf_appid."&secret=".$kf_secret."&code=".$code."&grant_type=authorization_code"; $temXML=$this->CURLSend($url,"get"); $objd=json_decode($temXML); $access_token =$objd->access_token; //$access_refresh_token=$objd->refresh_token; $openid=$objd->openid; //$access_refresh_token_time=date("Y-m-d H:i:s",strtotime("+30 day")); $unionid=$objd->unionid; ///请先到 微信开放平台绑定公众号 后才可以获取 unionid ; //检验授权凭证（access_token）是否有效 $urlu="https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN"; $temtXML=$this->CURLSend($urlu,"get"); $objy=json_decode($temtXML); $infoList=M('user')->field('gzh_openid,id,unionid')->where(array('unionid'=>$unionid))->find(); if(!empty($infoList['id'])){ $timed=date("Y-m-d H:i:s"); if(!empty($infoList['gzh_openid'])){ M('user')->where(array('unionid'=>$unionid))->save(array('time'=>$timed)); }else{ M('user')->where(array('unionid'=>$unionid))->save(array('time'=>$timed,"gzh_openid"=>$openid)); } $user_id=$infoList['id']; }else{ $data['gzh_openid'] = $openid; $data['username'] = $objy->nickname; $data['sex'] = $objy->sex; $data['avater'] = $objy->headimgurl; $data['country'] = $objy->country; $data['province'] = $objy->province; $data['city'] = $objy->city; $data['unionid'] = $unionid; $data['shop_id'] = 18; $data['ctime'] = date("Y-m-d H:i:s"); $ids=M('user')->add($data); $user_id=$ids; } //echo json_encode($objy);exit; } $_SESSION["user_id"]=$user_id; if($_SESSION["user_id"]){ $this->redirect("Home/GZHao/index"); } } public function index() { if($_SESSION["user_id"]){ //unset($_SESSION["user_id"]); $info = M("user")->field('gzh_openid')->where('id='.$_SESSION["user_id"])->find(); $user_name = "舞步天行者"; $openid = $info["gzh_openid"]; $time = date("Y-m-d H:i:s"); $name = "温斯顿"; $phone = "13926560746"; if($info["gzh_openid"]){ //存在发送消息 $myjson=$this->wx_moban($openid,$user_name,$time,$name,$phone); $url_fstzv="https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=".$this->getAccessToken(); $this->CURLSend($url_fstzv,"post",$myjson); } } $this->display(); } public function CURLSend($url, $method = 'get', $data = ''){ $ch = curl_init();//初始化 $headers = array('Accept-Charset: utf-8'); //设置URL和相应的选项 curl_setopt($ch, CURLOPT_URL, $url);//指定请求的URL curl_setopt($ch, CURLOPT_CUSTOMREQUEST, strtoupper($method));//提交方式 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);//不验证SSL curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);//不验证SSL curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);//设置HTTP头字段的数组 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible;MSIE5.01;Windows NT 5.0)');//头的字符串 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_AUTOREFERER, 1);//自动设置header中的Referer:信息 curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//提交数值 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);//是否输出到屏幕上,true不直接输出 $temp = curl_exec($ch);//执行并获取结果 curl_close($ch); return $temp;//return 返回值 } //微信模板发送 public function wx_moban($openid,$user_name,$l_name,$url_name,$end_time){ $wx_mo='{"touser":"'.$openid.'","template_id": "****************","url":"https://zs.kxsp.net/paimai/Api/Shop/","data": {"first": {"value": "尊敬的'.$user_name.'先生，您好！","color":"#173177"},"keyword1": {"value":"'.$l_name.'","color": "#173177"},"keyword2": {"value": "'.$url_name.'","color": "#173177"},"keyword3": {"value": "'.$end_time.'","color": "#173177"},"remark": {"value": "您的预约单已提交成功，我们将于24小时内与您联络并确认预约件的相关内容，请您保持手机畅通，祝您本次消费愉快！。","color": "#173177"}}}'; return $wx_mo; } //获取access_token,微信调用接口凭据(使用接口需要用到) //access_token获取频次2000/天,2小时内有效 public function getAccessToken(){ $shop_id=18;//店铺id $re=M('wx_gzh_config')->where('shop_id='.$shop_id)->find(); $kf_appid=$re['appid']; $kf_secret=$re['appsecret']; if($re['expires_in']<time()){ $url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$kf_appid."&secret=".$kf_secret; $tmp=$this->CURLSend($url,'get'); $obj=json_decode($tmp); $dty=(time()+$obj->expires_in); $data['access_token']=$obj->access_token; $data['expires_in']=$dty; M('wx_gzh_config')->where('shop_id='.$shop_id)->save($data); return $obj->access_token; }else { return $re['access_token']; } }
店铺id是我自己的，查询数据库要按照自己的情况来改我的代码，不要直接复制，template_id是你公众号自己申请的，
有不好地方可以留言，谢谢
