优化性能：许多CURL请求

我正在为客户端开发基于Web的RESTful API。除了一个请求之外，一切都很好，我需要为每一行请求Foursquare API。优化性能：许多CURL请求

此请求的URL是：3210。

目前到该URL的请求的响应是：

{ 
"response": { 
    "user": { 
     ... some user info ... 
     "times": [ 
      { 
       "id": "8", 
       "venue_fq_id": "4b81eb25f964a52000c430e3", 
       "user_id": "1", 
       "wait_length": "4468", 
       "created_at": "2012-06-09 21:45:43" 
      }, 
      { 
       "id": "9", 
       "venue_fq_id": "4aad285af964a520c05e20e3", 
       "user_id": "1", 
       "wait_length": "8512", 
       "created_at": "2012-06-09 21:45:43" 
      }, 
      { 
       "id": "10", 
       "venue_fq_id": "42377700f964a52024201fe3", 
       "user_id": "1", 
       "wait_length": "29155", 
       "created_at": "2012-06-09 21:45:44" 
      }, 
      { 
       "id": "11", 
       "venue_fq_id": "45c88764f964a5206e421fe3", 
       "user_id": "1", 
       "wait_length": "33841", 
       "created_at": "2012-06-09 21:45:44" 
      }, 
      { 
       "id": "12", 
       "venue_fq_id": "430d0a00f964a5203e271fe3", 
       "user_id": "1", 
       "wait_length": "81739", 
       "created_at": "2012-06-09 21:45:44" 
      } 
     ] 
    } 
}, 
"stat": "ok" 
}

然而，venue_fq_idresponse.user.times所述阵列中被返回相对于所述四方API的场所。我试着对每行的Foursquare API运行curl请求，但是性能非常慢。请您举例说明我可以如何加快性能，同时检索我每次访问时都要求的F/Q API的相同信息？

这里是我的代码：

$query = $this->db->query("SELECT * FROM `wait_times` WHERE `user_id` = ?", array($email_address)); 

$wait_times = $query->result(); 

foreach ($wait_times as $wait_time) { 

    $wait_time->venue = $this->venue_info($wait_time->venue_fq_id); 

} 

function venue_info($fq_id) { 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, "https://api.foursquare.com/v2/venues/4b522afaf964a5200b6d27e3"); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

    $response = json_decode(curl_exec($ch)); 
    curl_close($ch); 

    return $response['response']['venue']; 

}

你在浪费时间的可怕量实例/拆除卷曲的对象。这可以防止您利用HTTP保持活动，强制curl为您发出的每个请求启动一个新的tcp连接。

卷曲手柄CAN被重复使用。例如

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 


function venue_info($fq_id) { 
    global $ch; 
    curl_setopt($ch, CURLOPT_URL, "https://api.foursquare.com/v2/venues/4b522afaf964a5200b6d27e3"); 
    $resp = curl_exec($ch) or die(curl_error($ch)); 
    $json = json_decode($resp); 
    return($json); 
}

Foursquare的API提供了multi端点，让您最多合并到五个查询到一个单一的请求。

这需要在不登录的情况下完成。 – 2012-08-12 19:36:28
