使用 cURL twitter 获取空白页面

Question

我正在尝试使用带有 Codeigniter 框架的 PHP 添加一个 Twitter 帐户。
我得到一个空白页，即使在我的日志中也没有错误。不记名令牌是可以的，我直接在代码中添加了它进行测试。

我做错了什么？任何帮助表示赞赏。谢谢

控制器：manage.php

   if($_POST['platform'] == 'twitter'):

  $request = curl_init();
    $bearer = "AAAAAAAAAAAAAAAAAAAAAJ%xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; 
    curl_setopt($request, CURLOPT_SSLVERSION, 3);
    curl_setopt($request, CURLOPT_URL, 'https://api.twitter.com/1.1/application/rate_limit_status.json');
    curl_setopt($request, CURLOPT_HTTPHEADER, array('Authorization: Bearer '.$bearer));
    curl_setopt($request, CURLOPT_RETURNTRANSFER, true);
    $result = json_decode($content = curl_exec($request));
    curl_close($request);
    return($result);

    if($request == 0):
       $error = 'Sorry, rate limited';
    else:

        $account_data = @file_get_contents('http://api.twitter.com/1.1/users/show.json?screen_name='.$_POST['account_id'].'&include_entities=true');
        $account_data = json_decode($account_data);

    endif;

    if($account_data != false):
        $new_account = array(
            'id' => $account_data->screen_name,
            'username' => $account_data->screen_name,
            'name' => $account_data->name,
            'link' => 'https://twitter.com/'.$account_data->screen_name,
            'picture' => $account_data->profile_image_url,
            'platform' => 'twitter'
        );
    else:
        $error = "Account Not Found";
    endif;

视图：add.php

   <?php

   if(isset($error)) echo "<p>".$error."</p>";

echo '<form action="/manage/add" method="post" accept-charset="utf-8" style="margin-left:-15px; margin-top:-15px;">';

echo form_error('account_id');
echo '<strong>'.form_label('Account ID', 'account_id');
echo form_input('account_id', set_value('account_id', ''),'style="width: 288px;"');

    echo form_label('Platform', 'platform');
    echo form_dropdown('platform', $platforms, set_value('platform', $this->input->post('platform')));

$data = array('name' => 'submit', 'value' => 'Add Account', 'class' => 'submit');
echo form_submit($data);
  ?>

   <?php echo form_close(); ?>

当我将它设置为 CURLOPT_RETURNTRANSFER 时，我得到了 false。

Answer 1

您的 Authorization 标头看起来有误。要执行此类请求，您需要生成签名。更多信息请关注Twitter development site

我编写了一个 CodeIgniter 库，用于向 Twitter 发出 cURL 请求。您可能想要使用它，或者只是从中获取一些代码。仓库是here

Answer 2

我已经解决了这个问题。

  $request = curl_init();
    $bearer = "AAAAAAAAAAAAAAAAAAAAAJ%2xxxxxxxxxxxxxxx0x0x0x0x0x0x0x0x0x0xxxxxx"; 
    curl_setopt($request, CURLOPT_SSLVERSION, 3);
    curl_setopt($request, CURLOPT_URL, 'https://api.twitter.com/1.1/users/show.json?screen_name='.$account_id.'&include_entities=true');
    curl_setopt($request, CURLOPT_HTTPHEADER, array('Authorization: Bearer '.$bearer));
    curl_setopt($request, CURLOPT_RETURNTRANSFER, true);
    $account_data = json_decode($file_get_contents = curl_exec($request)); 
    curl_close($request);
