Question

我使用以下代码通过我的Facebook应用程序发布到我的页面墙上

$params = array(
    // this is the main access token (facebook profile)
   "access_token" => $access_token,
   "message" => "Here is a blog post about auto posting on Facebook without being signed in using PHP #php #facebook",
   "link" => $AD_Link,
   "picture" => "https://localhost/adwit1/uploaded_images/himanshu124/Lighthouse.jpg",
   "name" => $AD_Name,
   "caption" => $AD_Caption,
   "description" => $AD_Desc
);

try {
  $ret = $fb->api('/me/feed', 'POST', $params);
  echo 'Successfully posted to Facebook Personal Profile '.$ret['id'];
} catch(Exception $e) {
  echo $e->getMessage();
}

使用此代码，除了指定的图像外，所有内容都会发布在我的FB页面上。但是，如果我直接在浏览器中粘贴上面提到的图像链接，我就能够查看图像。另一方面，如果我在“picture”参数中使用以下链接http://i.imgur.com/lHkOsiH.png，则图像会在FB页面上发布。

我在stackoverflow.com上也发现了类似的问题，但没有提到令人满意的答案。

如果有人知道我遇到这样的问题，请帮助我。

Answer 1

您遇到此问题是因为Facebook无法读取本地主机服务器，唯一能够读取本地主机的人就是您，没有其他人。

您可以查看以下图片，因为它位于您的本地主机上。

https://localhost/adwit1/uploaded_images/himanshu124/Lighthouse.jpg

要解决此问题，请在任意图像商店网站上传图像然后获取其链接，在这种情况下，Facebook将能够读取图像。

        // post to Facebook
        // see: https://developers.facebook.com/docs/reference/php/facebook-api/
        try {
            $ret = $fb->api('/page id/feed', 'POST', $param);
            return "Successfully posted to Facebook";
            //$ret = $fb->api('/page id/feed', 'POST', $params);
            //echo 'Successfully posted to Facebook';
        } catch(Exception $e) {
            return $e;
            //echo $e->getMessage();
        }
    }

Locahost网址未被识别，因此请使用实时网站网址链接......例如www.example.com/images/profile.png

图片没有从localhost发布在facebook页面上
