这篇文章主要介绍的内容是关于PHP实现微信网页授权登陆，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下
公司要求有微信授权，自己研究了下，框架是tp3.2.
官方开发文档地址
1.识别浏览器，普通浏览器跳到登陆页面；微信打开的话，发起微信网页授权登陆，微信用户允许授权第三方应用后，微信会拉起应用或重定向到第三方网站，并且带上授权临时票据code参数；
2.通过code参数加上AppID和AppSecret等，通过API换取access_token；
3.通过access_token进行接口调用，获取用户基本数据资源或帮助用户实现基本操作。
<?phpnamespace Home\Controller;use Think\Controller;class CommonController extends Controller { /* * 自动执行 */ public function _initialize(){ //判断是否在微信打开 $ua = $_SERVER['HTTP_USER_AGENT']; //MicroMessenger 是android/iphone版微信所带的 //Windows Phone 是winphone版微信带的 (这个标识会误伤winphone普通浏览器的访问) if(strpos($ua, 'MicroMessenger') == false && strpos($ua, 'Windows Phone') == false){ //普通浏览器 if(!$_SESSION['username']) { header('Location:xxx'); } }else{ //微信浏览器 $users = M('User'); $appid = 'xxx'; $secret = 'xxx'; if(!$_SESSION['username']) { //微信网页授权 $redirect_uri = urlencode ('http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); $url ="https://open.weixin.qq.com/connect/oauth2/authorize?appid=$appid&redirect_uri=$redirect_uri&response_type=code&scope=snsapi_userinfo&state=1&connect_redirect=1#wechat_redirect"; header("Location:".$url); $code = $_GET["code"]; //第一步:取得openid $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code"; $oauth2 = $this->getJson($oauth2Url); //第二步:根据全局access_token和openid查询用户信息 $access_token = $oauth2["access_token"]; $openid = $oauth2['openid']; $get_user_info_url = "https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN"; $userinfo = $this->getJson($get_user_info_url); //save用户信息 if($userinfo['openid']){ $username = $userinfo['openid']; $nickname = $userinfo['nickname']; $headimg = $userinfo['headimgurl']; $province = $userinfo['province']; $city = $userinfo['city']; $sex = $userinfo['sex']; $user = $users->where(array('username' => $username))->find(); if ($user) { $users->where(array('username' => $username))->save(array('nickname' => $nickname, 'avatar' => $headimg, 'lasttime' => time())); }else{ $users->add(array('username' => $username, 'nickname' => $nickname, 'avatar' => $headimg, 'province' => $province, 'city' => $city, 'gender' => $sex, 'regtime' => time(), 'lasttime' => time())); // $data = array('username' => $username, 'nickname' => $nickname, 'avatar' => $headimg, 'province' => $province, 'city' => $city, 'gender' => $sex, 'regtime' => time(), 'lasttime' => time()); } $_SESSION['username'] = $username; if($user['tel'] == NULL){ //如果用户手机号为空的话跳转到绑定手机号页面 header('Location:xxx'); <i>*本5文来源gaodai$ma#com搞$$代**码)网@</i><img>搞代码gaodaima</img> } } }else{ $user = D('User')->getUserInfo(); //getUserInfo()是model根据session('username')获取用户数据的方法 if($user['tel'] == NULL){ header('Location:xxx'); } } //获取接口调用凭证access_token $accessurl = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$secret; $access_token = S('access_token'); if(!$access_token){ $access = $this->getJson($accessurl); if(!empty($access['access_token'])){ S('access_token',$access['access_token'],$access['expires_in']); } } //分享 /*$share = new WechatShare($appid, $_SESSION['username']); $this->shareScript = $share->getSgin($access_token); $this->assign('shareScript', $this->shareScript); $this->assign('sharewechaid', $_SESSION['username']); if($_GET['sharewechaid']){ $this->assign('getsharewechaid', $_GET['sharewechaid']); }*/ } } public function getJson($url){ $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); curl_close($ch); return json_decode($output, true); }}
