php – 在没有在线/登录的情况下发布到用户的墙 – 使用Graph AP

> Facebook绝不会与您分享用户密码！
>如果您只需要给用户分享链接的可能性,那么只需使用like plugin.您还可以在您的网站上找到更有趣的social plugins.
>如果您使用类似的插件,它将不会打开任何弹出窗口,它会将链接直接发布到用户的墙上.
>您可以随时使用Feed Dialog
>开始阅读Facebook Documentation

现在要在用户的墙上(代表他)发布而不登录,您需要以下内容：

> app access_token
> publish_stream权限,不需要长期访问令牌：

Enables your app to post content,comments,and likes to a user’s
stream and to the streams of the user’s friends. This is a superset
publishing permission which also includes publish_actions. However,
please note that Facebook recommends a user-initiated sharing model.
Please read the Platform Policies to ensure you understand how to
properly use this permission. Note,you do not need to request the
publish_stream permission in order to use the Feed Dialog,the
Requests Dialog or the Send Dialog.

需要许可：
这可以通过多种方式完成：
使用Login Plugin：

<div class="fb-login-button" data-show-faces="true" data-width="200" data-scope="publish_stream" data-max-rows="1"></div>

Server-side login(重定向到OAuth对话框)：

https://www.facebook.com/dialog/oauth?
     client_id=YOUR_APP_ID
     &redirect_uri=YOUR_URL
     &scope=publish_stream
     &state=SOME_ARBITRARY_BUT_UNIQUE_STRING

PHP-SDK：

$loginUrl = $facebook->getLoginUrl(array("scope"=>"publish_stream"));

JS-SDK通过FB.login方法：

FB.login(function(response) {
   if (response.authResponse) {
     console.log('Welcome!  Fetching your information.... ');
     FB.api('/me',function(response) {
       console.log('Good to see you,' + response.name + '.');
       FB.logout(function(response) {
         console.log('Logged out.');
       });
     });
   } else {
     console.log('User cancelled login or did not fully authorize.');
   }
 },{scope: 'publish_stream'});

出版：

$USER_ID = "XXXXXXXX"; // Connected once to your APP and not necessary logged-in at the moment
$args = array(
    'message'   => 'Hello from app','link'      => 'http://www.masteringapi.com/','caption'   => 'Visit MasteringAPI.com For Facebook API Tutorials!'
);
$post_id = $facebook->api("/$USER_ID/feed",$args);

注意：虽然可以在没有用户存在的情况下发布,但始终记得Facebook推荐用户启动的共享模型
