facebook php sdk不工作为什么？ [英] facebook php sdk does not work. why?

问题描述

我创建Facebook应用程序

I create facebook app

  require_once("facebook.php");

  $config = array();
  $config[‘appId’] = 'myid';
  $config[‘secret’] = 'mysecret';
  $config[‘fileUpload’] = false; // optional

  $facebook = new Facebook($config);

  $uid = $facebook->getUser();
  echo $uid;

但它不起作用。我的应用页面上看不到任何内容！为什么？

but it does not work. I see nothing on my app page! Why?

推荐答案

您可能会看不到任何原因。可能是$ uid不是字符串，但是一个对象和PHP正在抛出一个错误。您可以打开错误报告并找到错误。
也可能值得在uid上执行var_dump或print_r，uid可能不是您期望的

you may see nothing for a number of reason. One might be that $uid is not a string, but an object and php is throwing an error. You could turn error reporting on and find the error. also it might be worthwhile doing a var_dump or print_r on uid, uid might not be what you expect
