php 微信掃碼 pc端自動登陸註冊 用的介面scope 是snsapi_userinfo,微信登陸一個是網頁授權登陸,另一個是微信聯合登陸
網頁授權登陸:http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html
微信聯合登陸:https://open.weixin.qq.com/cgi-bin/frame?t=home/web_tmpl&lang=zh_CN
一:首先把微信連結帶個標識產生二維碼
比如連結為 https://open.weixin.qq.com/connect/oauth2/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,因為state你傳入什麼微信那邊返回什麼
可以作為伺服器與微信段的一個標識
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();
$value="https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx138697ef383a9167&redirect_uri=http://www.xxx.net/login/wcallback&response_type=code&scope=snsapi_userinfo&state=".$postdata."&connect_redirect=1#wechat_redirect";
$errorCorrectionLevel = "L";
$matrixPointSize = "5";
QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize);
}
}
此時產生了二維碼 state是標識,phpqrcode可以在文章末尾下載,這樣我們設定了回調地址http://www.xxx.net/login/wcallback
就可以在wcallback方法裡面處理資料 插入使用者 產生session,跳轉登陸,pc端可以設定幾秒鐘ajax請求伺服器,一旦擷取到了
state,即實現調整,微信瀏覽器裡處理完後可以關閉視窗,微信js可實現
document.addEventListener('WeixinJSBridgeReady', function onBridgeReady() {
WeixinJSBridge.call('closeWindow');
}, false);
也可以授權登陸成功後跳轉到微信服務號關注頁面
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 (empty($code)) $this->showMessage('授權失敗');
try{
$token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$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($token->errcode)) {
echo '
錯誤:
'.$token->errcode;
echo '
錯誤資訊:
'.$token->errmsg;
exit;
}
$access_token_url = 'https://api.weixin.qq.com/sns/oauth2/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token;
//轉成對象
$access_token = json_decode($this->https_request($access_token_url));
if (isset($access_token->errcode)) {
echo '
錯誤:
'.$access_token->errcode;
echo '
錯誤資訊:
'.$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'
//轉成對象
$user_info = json_decode($this->https_request($user_info_url));
if (isset($user_info->errcode)) {
echo '
錯誤:
'.$user_info->errcode;
echo '
錯誤資訊:
'.$user_info->errmsg;
exit;
}
//列印使用者資訊
// echo '
'// print_r($user_info);// echo '
'
phpqrcode類庫下載在此不提供各位可以百度搜尋下載
magento微信掃碼網站自動登入的例子
https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&lang=zh_CN
查看授權後介面調用(UnionID),不難發現填寫回調地址,使用者確認登陸pc端即可跳轉
擷取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 (empty($code)) $this->showMessage('授權失敗');
try{
$token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$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($token->errcode)) {
echo '<h1>錯誤:</h1>'.$token->errcode;
echo '<br/><h2>錯誤資訊:</h2>'.$token->errmsg;
exit;
}
$access_token_url = 'https://api.weixin.qq.com/sns/oauth2/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$token->refresh_token;
//轉成對象
$access_token = json_decode($this->https_request($access_token_url));
if (isset($access_token->errcode)) {
echo '<h1>錯誤:</h1>'.$access_token->errcode;
echo '<br/><h2>錯誤資訊:</h2>'.$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';
//轉成對象
$user_info = json_decode($this->https_request($user_info_url));
if (isset($user_info->errcode)) {
echo '<h1>錯誤:</h1>'.$user_info->errcode;
echo '<br/><h2>錯誤資訊:</h2>'.$user_info->errmsg;
exit;
}
//列印使用者資訊
// echo '<pre>';
// print_r($user_info);
// echo '</pre>';
//擷取unionid
$uid=$user_info->unionid;
}
//使用者操作處理 分為再次登入和第一次登陸
$sql="select h_user_id from dtb_user_binded as t1 left join dtb_user_weixin as t2 on t1.u_id=t2.id where t1.u_type='".
User::$arrUtype['weixin_num_t']."' and t2.openid='$user_info->unionid'";
$h_user_id = Core_Db::getOne($sql);
if(!empty($h_user_id)){//該weixin號再次登入
}{//該weixin號第一次登入
}
