這篇文章將為大家詳細(xì)講解有關(guān)怎么在php項(xiàng)目中實(shí)現(xiàn)一個(gè)微信掃碼登陸功能,文章內(nèi)容質(zhì)量較高,因此小編分享給大家做個(gè)參考,希望大家閱讀完這篇文章后對(duì)相關(guān)知識(shí)有一定的了解。
一、首先把微信鏈接帶個(gè)標(biāo)識(shí)生成二維碼
比如鏈接為 https://open.weixin.qq.com/connect/oauth3/authorize?appid='.$appid.'&redirect_uri='.$url.'&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect' 我們可以在state上做文章,因?yàn)閟tate你傳入什么微信那邊返回什么
可以作為服務(wù)器與微信段的一個(gè)標(biāo)識(shí):
public function creatqrAction(){ if($_GET['app']){ $wtoken=$_COOKIE['wtoken']; $postdata=$_SESSION['w_state']; if($wtoken){ $postdata=$wtoken; } include CONFIG_PATH . 'phpqrcode/'.'phpqrcode.php' $sh=$this->shar1(); $value="https://open.weixin.qq.com/connect/oauth3/authorize?appid=wx138697ef383a9167&redirect_uri=http://www.xxx.net/login/wcallback&response_type=code&scope=snsapi_userinfo&state=".$postdata."&connect_redirect=1#wechat_redirect"; $errorCorrectionLevel = "L"; $matrixPointSize = "5"; QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize); } }
此時(shí)生成了二維碼 state是標(biāo)識(shí),phpqrcode可以在文章末尾下載,這樣我們?cè)O(shè)置了回調(diào)地址http://www.xxx.net/login/wcallback
就可以在wcallback方法里面處理數(shù)據(jù) 插入用戶 生成session,跳轉(zhuǎn)登陸,pc端可以設(shè)置幾秒鐘ajax請(qǐng)求服務(wù)器,一旦獲取到了state,即實(shí)現(xiàn)調(diào)整,微信瀏覽器里處理完后可以關(guān)閉窗口,微信js可實(shí)現(xiàn):
document.addEventListener('WeixinJSBridgeReady', function onBridgeReady() { WeixinJSBridge.call('closeWindow');}, false);
也可以授權(quán)登陸成功后跳轉(zhuǎn)到微信服務(wù)號(hào)關(guān)注頁面:
header("Location: weixin://profile/gh_a5e1959f9a4e"); wcallback方法做處理登陸 $code = $_GET['code']; $state = $_GET['state']; $setting = include CONFIG_PATH . 'setting.php' $appid=$setting['weixin']['appid']; $appsecret=$setting['weixin']['appsecret']; if (emptyempty($code)) $this->showMessage('授權(quán)失敗'); try{ $token_url = 'https://api.weixin.qq.com/sns/oauth3/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code' $token = json_decode($this->https_request($token_url)); }catch(Exception $e) { print_r($e); } if (isset($token->errcode)) { echo '錯(cuò)誤:'.$token->errcode; echo '錯(cuò)誤信息:'.$token->errmsg; exit; } $access_token_url = 'https://api.weixin.qq.com/sns/oauth3/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token; //轉(zhuǎn)成對(duì)象 $access_token = json_decode($this->https_request($access_token_url)); if (isset($access_token->errcode)) { echo '錯(cuò)誤:'.$access_token->errcode; echo '錯(cuò)誤信息:'.$access_token->errmsg; exit; } $user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token->access_token.'&openid='.$access_token->openid.'&lang=zh_CN' //轉(zhuǎn)成對(duì)象 $user_info = json_decode($this->https_request($user_info_url)); if (isset($user_info->errcode)) { echo '錯(cuò)誤:'.$user_info->errcode; echo '錯(cuò)誤信息:'.$user_info->errmsg; exit; } //打印用戶信息 // echo '' // print_r($user_info); // echo ''
phpqrcode類庫下載在此不提供各位可以百度搜索下載
magento微信掃碼網(wǎng)站自動(dòng)登錄的例子
https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&lang=zh_CN
查看授權(quán)后接口調(diào)用(UnionID),不難發(fā)現(xiàn)填寫回調(diào)地址,用戶確認(rèn)登陸pc端即可跳轉(zhuǎn)
獲取UnionID方法
public function wcallbackAction(){ $code = $_GET['code']; $state = $_GET['state']; $setting = include CONFIG_PATH . 'setting.php'; $appid=$setting['weixin']['appid']; $appsecret=$setting['weixin']['appsecret']; if (emptyempty($code)) $this->showMessage('授權(quán)失敗'); try{ $token_url = 'https://api.weixin.qq.com/sns/oauth3/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code'; $token = json_decode($this->https_request($token_url)); }catch(Exception $e) { print_r($e); } if (isset($token->errcode)) { echo '<h2>錯(cuò)誤:</h2>'.$token->errcode; echo '<br/><h3>錯(cuò)誤信息:</h3>'.$token->errmsg; exit; } $access_token_url = 'https://api.weixin.qq.com/sns/oauth3/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token; //轉(zhuǎn)成對(duì)象 $access_token = json_decode($this->https_request($access_token_url)); if (isset($access_token->errcode)) { echo '<h2>錯(cuò)誤:</h2>'.$access_token->errcode; echo '<br/><h3>錯(cuò)誤信息:</h3>'.$access_token->errmsg; exit; } $user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token->access_token.'&openid='.$access_token->openid.'&lang=zh_CN'; //轉(zhuǎn)成對(duì)象 $user_info = json_decode($this->https_request($user_info_url)); if (isset($user_info->errcode)) { echo '<h2>錯(cuò)誤:</h2>'.$user_info->errcode; echo '<br/><h3>錯(cuò)誤信息:</h3>'.$user_info->errmsg; exit; } //打印用戶信息 // echo '<pre>'; // print_r($user_info); // echo '</pre>'; //獲取unionid $uid=$user_info->unionid; } //用戶操作處理 分為再次登錄和第一次登陸 $sql="select h_user_id from dtb_user_binded as t1 left join dtb_user_weixin as t2 on t1.u_id=t2.id where t1.u_type='". User::$arrUtype['weixin_num_t']."' and t2.openid='$user_info->unionid'"; $h_user_id = Core_Db::getOne($sql); if(!emptyempty($h_user_id)){//該weixin號(hào)再次登錄 }{//該weixin號(hào)第一次登錄 }
