将图片张贴到Facebook墙上 [英] Post a picture to a facebook wall

问题描述

我有一个功能来发布一个链接到Facebook的墙壁。这样做应该是，只有我尝试附加的图像才会显示在页面上。

我必须做一些特殊的事情来发布图像？

  public function shareAction（）
 {
 include_once（'/ application / modules / social / services /facebook/facebook.php'）; 
 
 $ request = $ this-> getRequest（）; 
 $ this-> _helper-> getHelper（'viewRenderer'） - > setNoRender（）; 
 $ this-> _helper-> getHelper（'layout'） - > disableLayout（）; 
 
 $ return ='ERROR'; 
 
 if（$ request-> isPost（））{
 $ file = TOMATO_APP_DIR。 DS。 '模块'。 DS。 社会。 DS。 'config'。 DS。 的config.ini; 
 $ config = new Zend_Config_Ini（$ file）; 
 $ config = $ config-> toArray（）; 
 
 //创建我们的应用程序实例（将其替换为您的appId和密码）。 
 $ facebook = new Facebook（array（
'appId'=> $ config ['facebook'] ['appId']，
'secret'=> $ config ['facebook '] ['secret']，
'cookie'=> true，
））; 
 
 $ options = Array（
'access_token'=> $ config ['facebook'] ['pageAccessToken']，
'link'=> $ request-> ; getPost（'link'），
'picture'=>'@'$ request-> getPost（'picture'），
'name'=> $ request-> getPost （'name'），
'caption'=> $ request-> getPost（'caption'），
'description'=> $ request-> getPost（'description' 
）; 
 // Zend_Debug :: dump（$ options）;死（）; 
 $ wallPost = $ facebook-> api（'/ me / feed'，'post'，$ options）; 
 
 $ return ='SUCCESS'; 
} 
 
 echo $ return; 
} 
  

除图像外，一切都按预期方式运行。任何想法为什么？

解决方案

作为Brent和akond提到，图片链接不应以'@'为前缀，应该是一个简单的URL（大概是缩略图大小的）图像。例如，这个卷曲命令的作用如下：

  set + H＃首先关闭历史记录扩展
 curl -F \\ \\ 
picture = http：//tycho.usno.navy.mil/gif/moons/m146.gif\ 
 -Fmessage =你今晚看起来很棒！ \ 
 -Fname =当前月相\ 
 -Flink = http：//www.calculatorcat.com/moon_phases/phasenow.php-F caption =如何月亮今天晚上出现\ 
 -Faccess_token = 111111111111111 | 2222222222222222222222222 | 33333333333333333333456n\

更新：在@mlunoe指出感叹号由Bash历史扩展器插值之后，我不知道上述如何没有使用 set + H 。我用单引号测试，没有解决问题，所以在设置解决方案/cant-use-exclamation-mark-in-bash\"> https://unix.stackexchange.com/questions/33339/cant-use-exclamation-mark-in-bash

I have t function to post a link to a Facebook-wall. This works like it should, only the image I try to attach to it doesn't show up on the page.

Do I have to do something special to post an image?

public function shareAction()
{
    include_once('/application/modules/social/services/facebook/facebook.php');

    $request = $this->getRequest();
    $this->_helper->getHelper('viewRenderer')->setNoRender();
    $this->_helper->getHelper('layout')->disableLayout();

    $return = 'ERROR';

    if($request->isPost()) {
        $file   = TOMATO_APP_DIR . DS . 'modules' . DS . 'social' . DS . 'config' . DS . 'config.ini';
  $config = new Zend_Config_Ini($file);
  $config = $config->toArray();

        // Create our Application instance (replace this with your appId and secret).
        $facebook = new Facebook(array(
          'appId'  => $config['facebook']['appId'],
          'secret' => $config['facebook']['secret'],
          'cookie' => true,
        ));

        $options = Array(
            'access_token' => $config['facebook']['pageAccessToken'],
            'link' => $request->getPost('link'),
            'picture' => '@' . $request->getPost('picture'),
            'name' => $request->getPost('name'),
            'caption' => $request->getPost('caption'),
            'description' => $request->getPost('description'),
        );
        //Zend_Debug::dump($options); die();
        $wallPost = $facebook->api('/me/feed', 'post', $options);

        $return = 'SUCCESS';
    }

    echo $return;
}

Everything works as expected except the image. Any idea why please?

解决方案

as Brent and akond mentioned, the picture link should not be prefixed by '@', it should be a simple URL to a (presumably thumbnail-sized) image. This curl command, for example, works:

set +H  # first turn off history expansion
curl -F \
     "picture=http://tycho.usno.navy.mil/gif/moons/m146.gif" \
     -F "message=you're looking great tonight!" \
     -F "name=Current Moon Phase" \
     -F "link=http://www.calculatorcat.com/moon_phases/phasenow.php" -F caption="How the moon appears tonight" \
     -F "access_token=111111111111111|2222222222222222222222222|33333333333333333333456n" \
     "https://graph.facebook.com/215958041750734/feed"

you can see the result at https://www.facebook.com/home.php#!/pages/The-Moon/215958041750734

update: I don't know how the above worked without the set +H, after @mlunoe pointed out that the exclamation point is interpolated by the Bash history expander. I tested with single quotes and didn't solve the problem, so found the set solution at https://unix.stackexchange.com/questions/33339/cant-use-exclamation-mark-in-bash
