标签: php facebook flash oauth facebook-php-sdk

我正在尝试在Facebook上获取我的团队的Flash项目,但我无法使用任何PHP-SDK示例。我已经关注了几个例子,例如github上的这个新例子(here)。但是,我不断收到解析错误:

  

解析错误:语法错误,意外'{'in   /home/content/r/a/s/rashomon/html/projects/facebook/test/hellomyflash/index.php   在第36行

我下载了最新的PHP-SDK。这是我的文件结构:

.../hellomyflash/

   index.php

   src/base_facebook.php

   src/facebook.php

   src/fb_ca_chain_bundle.crt

我在index.php中更改的只有两行是appId和secret。

index.php:

require '../src/facebook.php';

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

// Get User ID
$user = $facebook->getUser();

// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}

// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');

在关注this示例时,我遇到了“意外”{“”错误。

我做错了什么???

2 个答案:

答案 0 :(得分:5)

您的服务器很可能运行PHP4,提供的代码适用于PHP5。

PHP4没有try / catch块。

答案 1 :(得分:0)

如果你进入“facebook.php”和“base_facebook.php”,那么php的关闭标签将丢失,页面底部会显示“?&gt;”。我听说这给某些人带来了问题,当他们添加了关闭标签时它就得到了解决。你可以尝试;)

但是看到老兄对我的回答后,这可能是正确的答案! :P
