//***方法一
获取code
https://open.weixin.qq.com/connect/oauth2/authorize?appid=这里是你的公众号的APPID&redirect_uri=http://www.xx.com/getcode&response_type=code&scope=snsapi_userinfo&state=123#wechat_redirect
用户点击确认登录,自动跳转下面地址得到code
http://www.xx.com/getcode 这个是你自己的跳转地址
http://www.xx.com/getcode?code=0064f7afef7af7b395147bfe8b51f7bf&state=123
后面的这个 ?code=……123 是微信自动跳转添加的,不是你自己加的
下面是PHP语言,写在getcode这个页面里
$code = $_GET['code'];//获取code
$weixin = file_get_contents("https://api.weixin.qq.com/sns/oauth2/access_token?appid=这里是你的APPID&secret=这里是你的SECRET&code=".$code."&grant_type=authorization_code");//通过code换取网页授权access_token
$jsondecode = json_decode($weixin); //对JSON格式的字符串进行编码
$array = get_object_vars($jsondecode);//转换成数组
$openid = $array['openid'];//输出openid
//***方法二
$appid = "公众号在微信的appid";
$secret = "公众号在微信的app secret";
$code = $_GET["code"];
$get_token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$secret.'&code='.$code.'&grant_type=authorization_code';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$get_token_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
$res = curl_exec($ch);
curl_close($ch);
$json_obj = json_decode($res,true);
//根据openid和access_token查询用户信息
$access_token = $json_obj['access_token'];
$openid = $json_obj['openid'];
$get_user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$get_user_info_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
$res = curl_exec($ch);
curl_close($ch);
//解析json
$user_obj = json_decode($res,true);
$_SESSION['user'] = $user_obj;
print_r($user_obj);
