微信網站應用掃碼登陸
1、js二維碼code
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>微信掃碼登陸</title> <script type="text/javascript" src="/app/static/wxLogin.js"></script> </head> <body> <div id="login_container"> </div> <script type="text/javascript"> var obj = new WxLogin({ self_redirect:true, id:"login_container", appid: "", scope: "snsapi_login", redirect_uri: "{$redirect_uri}", state: "", style: "black", href: "LmltcG93ZXJCb3ggLnFyY29kZSB7d2lkdGg6IDIwMHB4O30KLmltcG93ZXJCb3ggLnRpdGxlIHtkaXNwbGF5OiBub25lO30KLmltcG93ZXJCb3ggLmluZm8ge3dpZHRoOiAyMDBweDt9Ci5zdGF0dXNfaWNvbiB7ZGlzcGxheTogbm9uZX0KLmltcG93ZXJCb3ggLnN0YXR1cyB7dGV4dC1hbGlnbjogY2VudGVyO30g" }); </script> </body> </html>
2、接受code，生成openid
//獲取微信二維碼掃碼登陸 $tokens="https://api.weixin.qq.com/sns/oauth2/access_token?appid=&secret=&code={$code}&grant_type=authorization_code"; $this->oLogAct->add("微信掃碼登陸獲取二維碼token地址" . json_encode($tokens)); $tokens=$this->setGet($tokens); $this->oLogAct->add("微信掃碼登陸獲取二維碼token資訊" . json_encode($tokens)); if (empty($tokens)) { return self::setMsg(500, '登入失敗!'); } $openid=base64_encode($this->encryptData($tokens['openid']));
