编辑后的问题：
我试图在我的 WordPress 网站上使用 Facebook 登录插件this sdk https://stackoverflow.com/questions/6034813/facebook-uncaught-oauthexception-an-active-access-token-must-be-used-to-query-i?answertab=active#tab-top
当我点击 facebook 按钮登录或注册时，它会通过 facebook 打开一个小窗口，显示“继续”，但之后它不会在 wordpress 数据库中创建用户并破坏 wordpress 页脚，所以它显示An active access token must be used to query information about the current user.页面刷新后登录表单下的消息。
我完整的 facebook 登录 php 代码是这样的：
<?php
include 'facebook/facebook.php';
function gazi_fb_loginForm(){
gazi_fb_error_message();
gazi_fb_LoadScript();
if(is_user_logged_in()==false){
?>
<div class="facebook_wrapper">
<img src="<?php echo plugin_dir_url(__FILE__).'images/facebook_or.png';?>" style="border:none; box-shadow:none;">
<br>
<a href="javascript:void(0)" onClick="FBLogin();">
<img src="<?php echo plugin_dir_url(__FILE__).'images/facebook_button.png';?>" alt="Fb Connect" title="Login with facebook" /></a></div>
<?php
}
}
function gazi_fb_LoadScript(){
global $wpdb;
$gazi_option=$wpdb->prefix."gazi_option";
$path = plugin_dir_url(__FILE__); // define path to link and scripts
$pageURL = get_permalink();
$sign = strpos($pageURL,'?')?'&':'?';
//facebook app secret
$qry1="SELECT value FROM $gazi_option WHERE fieldname='gazi_facebook_app_secret'";
$facebook_app_secret = $wpdb->get_var($qry1);
$qry2="SELECT value FROM $gazi_option WHERE fieldname='gazi_facebook_app_id'";
$facebook_app_id = $wpdb->get_var($qry2);
$facebook = new Facebook(array(
'appId' => $facebook_app_id,
'secret' => $facebook_app_secret,
));
?>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({
appId : '<?php echo $facebook_app_id; ?>',
xfbml : true,
status : true,
cookie : true,
version : 'v2.1'
});
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log('Logged in.');
}
else {
console.log('initiate FB login...');
FB.login();
}
});
FB.api('/me/feed',function(response){
var idDiv=document.getElementById('result');
idDiv.textContent=JSON.stringify(response);
});
};
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function FBLogin(){
FB.login(function(response){
if(response.authResponse){
window.location.href = "<?php echo $pageURL.$sign;?>option=fblogin";
}
}, {scope: 'email'});
}
</script>
<?php
}
function gazi_fb_error_message(){
if(isset($_SESSION['msg'])){
echo '<div class="'.$_SESSION['msg_class'].'">'.$_SESSION['msg'].'</div>';
unset($_SESSION['msg']);
unset($_SESSION['msg_class']);
}
}
function gazi_fb_login_validate(){
$path = plugin_dir_url(__FILE__); // define path to link and scripts
$pageURL = get_permalink();
$sign = strpos($pageURL,'?')?'&':'?';
if(isset($_REQUEST['option']) && $_REQUEST['option'] == "fblogin"){
global $wpdb;
$gazi_option=$wpdb->prefix."gazi_option";
//facebook app secret
$qry1="SELECT value FROM $gazi_option WHERE fieldname='gazi_facebook_app_secret'";
$facebook_app_secret = $wpdb->get_var($qry1);
$qry2="SELECT value FROM $gazi_option WHERE fieldname='gazi_facebook_app_id'";
$facebook_app_id = $wpdb->get_var($qry2);
$facebook = new Facebook(array(
'appId' => $facebook_app_id,
'secret' => $facebook_app_secret,
'cookie' => TRUE,
));
$fbuser = $facebook->getUser();
if ($fbuser) {
try {
$user_profile = $facebook->api('/me');
}
catch (Exception $e) {
echo $e->getMessage();
exit();
}
if (!isset($user_profile['email'])) $user_profile['email'] = $user_profile['id'] . '@facebook.com';
$user_fbid = $fbuser;
$user_email = $user_profile["email"];
$user_fnmae = $user_profile["first_name"];
if( email_exists( $user_email )) { // user is a member
$user = get_user_by('login', $user_email );
$user_id = $user->ID;
wp_set_auth_cookie( $user_id, true );
} else { // this user is a guest
$random_password = wp_generate_password( 10, false );
$user_id = wp_create_user( $user_email, $random_password, $user_email );
update_user_meta($user_id, 'avtar_image', 'https://graph.facebook.com/' . $user_profile['id'] . '/picture?type=large');
wp_update_user(array(
'ID' => $user_id,
'display_name' => $user_profile['name'],
'first_name' => $user_profile['first_name'],
'last_name' => $user_profile['last_name']
));
wp_set_auth_cookie( $user_id, true );
}
wp_redirect( $pageURL.$sign.'login4=1');
exit;
}
}
}
?>
这是上面代码中的 javascript。
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({
appId : '<?php echo $facebook_app_id; ?>',
xfbml : true,
status : true,
cookie : true,
version : 'v2.1'
});
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log('Logged in.');
}
else {
console.log('initiate FB login...');
FB.login();
}
});
FB.api('/me/feed',function(response){
var idDiv=document.getElementById('result');
idDiv.textContent=JSON.stringify(response);
});
};
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function FBLogin(){
FB.login(function(response){
if(response.authResponse){
window.location.href = "<?php echo $pageURL.$sign;?>option=fblogin";
}
}, {scope: 'email'});
}
</script>
有谁知道如何让它发挥作用？我做错了什么？非常感谢任何帮助。
谢谢。
UPDATE:
我使用这个答案更改了文件中的一些行here https://stackoverflow.com/questions/6034813/facebook-uncaught-oauthexception-an-active-access-token-must-be-used-to-query-i?answertab=active#tab-top
改变了这一点：
$fbuser = $facebook->getUser();
if ($fbuser) {
try {
$user_profile = $facebook->api('/me');
}
catch (Exception $e) {
echo $e->getMessage();
exit();
}
对于这个：
$fbuser = $facebook->getUser();
$photo_details = array('message' => 'my place');
$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);
if ($fbuser) {
try {
// We have a valid FB session, so we can use 'me'
$upload_photo = $facebook->api('/me/photos', 'post', $photo_details);
} catch (FacebookApiException $e) {
error_log($e);
}
我现在已经注册了，但是很奇怪
WordPress 的用户名和昵称始终是@facebook :D
所以我认为它没有在这里获取变量：
if (!isset($user_profile['email'])) $user_profile['email'] = $user_profile['id'] . '@facebook.com'; and just keeping @facebook instead without the `$user_profile['id']`
