Question

我正在尝试使用带有symfony2和twig的Twitter API 1.1。到目前为止，我已成功将所有推文作为数组传递给模板，但我无法获取最新的推文。

除了数字或帖子之外，一切正常，所以我发布了完整的代码来帮助其他人。

推特功能

public function buildBaseString($baseURI, $method, $params) {
    $r = array();
    ksort($params);
    foreach($params as $key=>$value){
        $r[] = "$key=" . rawurlencode($value);
    }
    return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));
}

public function buildAuthorizationHeader($oauth) {
    $r = 'Authorization: OAuth ';
    $values = array();
    foreach($oauth as $key=>$value)
        $values[] = "$key=\"" . rawurlencode($value) . "\"";
    $r .= implode(', ', $values);
    return $r;
}

public function twitter_latest(){
$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";

$oauth_access_token = "***";
$oauth_access_token_secret = "***";
$consumer_key = "***";
$consumer_secret = "***";

$oauth = array( 'oauth_consumer_key' => $consumer_key,
                'oauth_nonce' => time(),
                'oauth_signature_method' => 'HMAC-SHA1',
                'oauth_token' => $oauth_access_token,
                'oauth_timestamp' => time(),
                'oauth_version' => '1.0');

$base_info = $this->buildBaseString($url, 'GET', $oauth);
$composite_key = rawurlencode($consumer_secret) . '&' . rawurlencode($oauth_access_token_secret);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;

// Make Requests
$header = array($this->buildAuthorizationHeader($oauth), 'Expect:');
$options = array( CURLOPT_HTTPHEADER => $header,
                  //CURLOPT_POSTFIELDS => $postfields,
                  CURLOPT_HEADER => false,
                  CURLOPT_URL => $url,
                  CURLOPT_RETURNTRANSFER => true,
                  CURLOPT_SSL_VERIFYPEER => false);

$feed = curl_init();
curl_setopt_array($feed, $options);
$json = curl_exec($feed);
curl_close($feed);

$twitter_data = json_decode($json);

return $twitter_data;
}

控制器：

/**
  * Index page 
  *
  */
public function indexAction() 
{
   $twitters = $this->twitter_latest();
   return $this->render('mwwqTestBundle:Main:index.html.twig', array("twitters" => $twitters));

}

Twig模板：

<div id="mainTwitter">
   <ul id="twitter_update_list">
    {% for twitter in twitters %}  
        {{ twitter.text }}
    {% endfor %}
   </ul>
</div>

{{ twitter.text[0] }}, {{ twitter[0].text }}, {{ twitter.text.[0] }}无效

如果您只想显示一条推文，为什么需要将多条推文传递给视图？

你可以这样做：

{% if loop.first %}
    {{ twitter.text }}
{% endif %}

要更改控制器中的计数：

据推测，您只是想直接更改url变量。我认为你需要做类似以下的事情。当然，我已经在某个地方看到它，但找不到原作者：

public function twitter_latest($count = 1){
$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";

$oauth_access_token = "***";
$oauth_access_token_secret = "***";
$consumer_key = "***";
$consumer_secret = "***";

$oauth = array( 'count' => $count,
                'oauth_consumer_key' => $consumer_key,
                'oauth_nonce' => time(),
                'oauth_signature_method' => 'HMAC-SHA1',
                'oauth_token' => $oauth_access_token,
                'oauth_timestamp' => time(),
                'oauth_version' => '1.0');

$base_info = $this->buildBaseString($url, 'GET', $oauth);
$composite_key = rawurlencode($consumer_secret) . '&' . rawurlencode($oauth_access_token_secret);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;

// Make Requests
$header = array($this->buildAuthorizationHeader($oauth), 'Expect:');
$options = array( CURLOPT_HTTPHEADER => $header,
                  //CURLOPT_POSTFIELDS => $postfields,
                  CURLOPT_HEADER => false,
                  CURLOPT_URL => $url . '&count=' . $count,
                  CURLOPT_RETURNTRANSFER => true,
                  CURLOPT_SSL_VERIFYPEER => false);

$feed = curl_init();
curl_setopt_array($feed, $options);
$json = curl_exec($feed);
curl_close($feed);

$twitter_data = json_decode($json);

return $twitter_data;
}

Answer 2

{% for twi in tweet|slice(0, 2)%}
<li>
<div>{{twi.text}}</div>
<small><strong>{{twi.created_at|date("m/d/Y")}}</strong></small>
</li>
{% endfor %}
