1.必须配置回调函数(在微信开发者管理中)
2.用户授权并获取code
在域名（前面配置的回调域名）根目录下，新建一个文件，命名为oauth.php(名字随便你取，下面的redirect_uri做相应修改即可）
url: https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx3baef8c48cce7fb3&redirect_uri=http%3a%2f%2fh5.tybxkj.cc%2foauth.php&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect
3.使用code换取access_token
利用get请求函数访问url
https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx3baef8c48cce7fb3&secret=4ca91b29cf3370b2ad311565344b598a&code=$coded&grant_type=authorization_code
4.通过access_token、openid获取用户信息
url: https://api.weixin.qq.com/sns/userinfo?access_token=$acctke&openid=$appid
5.通过单击菜单带参数(state)判断用户跳转链接
查询数据库中有无注册记录
$pdcz = $db->get_one("select * from destoon_member where destoon_member.oppid=‘$appid‘");
有则直接登陆
$names = $pdcz[‘username‘];
$pasmd = $pdcz[‘password‘].$pdcz[‘passsalt‘];
$do = new member;
$user = $do->login($names,$pasmd,86300*30,true); //调用框架内部登陆
// 重定向
if($user){
header("Location: http://h5.tybxkj.cc/mobile/news/");
}
无则注册并登陆
$do = new member;
$data[‘regid‘] = ‘5‘;
$data[‘company‘] = null;
$data[‘username‘] = $nameu;
$data[‘password‘] = $pass;
$data[‘cpassword‘] = $pass;
$data[‘passport‘] = $nameu;
$data[‘truename‘] = $truenme;
$data[‘groupid‘] = ‘5‘;
$data[‘catids‘] = ‘111‘;
$data[‘catid‘] = ‘2‘;
$data[‘banner‘] = ‘11‘;
$data[‘thumb‘] =‘111‘ ;
$data[‘introduce‘] = ‘22‘;
$data[‘content‘] = ‘333‘;
$data[‘edittime‘] = 0;
$data[‘inviter‘] = ‘1111‘;
$data[‘oppid‘] = $appid;
$data[‘wxhead‘] = $imgtx;
$user = $do->add($data); //注册方法
if($user){
$goa = $do->login($data[‘username‘],$data[‘password‘],86300*30,true);
if($goa){
header("Location: http://h5.tybxkj.cc/mobile/news/"); //重定向
}
}
6.参考函数
//get请求
function curl_get_https($url){
$curl = curl_init(); // 启动一个CURL会话
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); // 从证书中检查SSL加密算法是否存在
$tmpInfo = curl_exec($curl); //返回api的json对象
//关闭URL请求
curl_close($curl);
return $tmpInfo; //返回json对象
}
