WordPress 使用微博登录功能的实现

把以下代码添加到你的function.php文件里。

<?php
define(‘WB_APPID’,’你的appkey’);//appkey
define(‘WB_APPSECRET’,’你的appsecret’);//appsecret
function wb_ouath_redirect(){
$url = home_url();
wp_redirect( $url );
exit;
}
function wb_get_access_token($code){
$url = “https://api.weibo.com/oauth2/access_token”;
$data = array(‘client_id’ => WB_APPID,
‘client_secret’ => WB_APPSECRET,
‘grant_type’ => ‘authorization_code’,
‘redirect_uri’ => home_url(),
‘code’ => $code);
$response = wp_remote_post( $url, array(
‘method’ => ‘POST’,
‘body’ => $data,
)
);
$output = json_decode($response[‘body’],true);
return $output;
}
function weibo_oauth(){
if(!isset($_GET[‘code’])) wp_die(‘code empty.’);
$code = $_GET[‘code’];
$output = wb_get_access_token($code);
$sina_access_token = $output[‘access_token’];

wp_die(‘服务器响应错误。’);
}
$get_user_info_url = “https://api.weibo.com/2/users/show.json?uid=”.$sina_uid.”&access_token=”.$sina_access_token;
$usersina = wp_remote_get( $get_user_info_url );
$userinfo = json_decode($usersina[‘body’] , true);
$username = $userinfo[‘screen_name’];
$avatar = $userinfo[‘profile_image_url’];
if(is_user_logged_in()){
$this_user = wp_get_current_user();
update_user_meta($this_user->ID ,”sina_uid”,$sina_uid);
update_user_meta($this_user->ID ,”sina_access_token”,$sina_access_token);
update_user_meta($this_user->ID ,”sina_avatar”,$avatar);
wb_ouath_redirect();
}else{
$user_weibo = get_users(array(“meta_key “=>”sina_uid”,”meta_value”=>$sina_uid));
if(is_wp_error($user_weibo) || !count($user_weibo)){
$login_name = wp_create_nonce($sina_uid);
$random_password = wp_generate_password( $length=12, $include_standard_special_chars=false );
$userdata=array(

$user_id = wp_insert_user( $userdata );
wp_signon(array(“user_login”=>$login_name,”user_password”=>$random_password),false);
update_user_meta($user_id ,”sina_uid”,$sina_uid);
update_user_meta($user_id ,”sina_access_token”,$sina_access_token);
update_user_meta($user_id ,”sina_avatar”,$avatar);
wb_ouath_redirect();
}else{
update_user_meta($user_weibo[0]->ID ,”sina_access_token”,$sina_access_token);
update_user_meta($user_weibo[0]->ID ,”sina_avatar”,$avatar);
wp_set_auth_cookie($user_weibo[0]->ID);
wb_ouath_redirect();
}
}
}
function social_oauth_weibo(){
if (isset($_GET[‘code’])){
weibo_oauth();
}
}
add_action(‘init’,’social_oauth_weibo’);

function weibo_oauth_url(){
$url = ‘https://api.weibo.com/oauth2/authorize?client_id=’ . WB_APPID . ‘&response_type=code&redirect_uri=’ . urlencode (home_url());
return $url;
}
