php - 如何使用 cURL 在 PHP 中将我的代码转换为同步 http 请求

Question

我想使用 PHP 和 cURL 将以下代码转换为同步 http 请求

   $select_ids = $db->query("SELECT job_id, tids FROM sent_items");    
    if ($select_ids->num_rows) {
        while($row = $select_ids->fetch_object()) {
            $records[] = $row;            
        }
        $select_ids->free();
    }

    print_r($records);

    if(!count($records)) {
        echo 'No records';
    } else {
        foreach ($records as $r) {      
            $chandle = curl_init();    
            $url = "http://api.mvaayoo.com/apidlvr/APIDlvReport?user=USER ID:PASSWORD&tid=$r->tids&jobid=$r->job_id";    
            curl_setopt($chandle, CURLOPT_URL, $url);    
            curl_setopt($chandle, CURLOPT_RETURNTRANSFER, 1);    
            $curl_result[] = curl_exec($chandle);
        }    
    }

print_r($records); returns jobid and tid

参见 Here

我将作业 ID 和 tid 提供给 api url

$url = "http://api.mvaayoo.com/apidlvr/APIDlvReport?user=USER ID:PASSWORD&tid=$r->tids&jobid=$r->job_id";

tid=$r->tids&jobid=$r->job_id

$curl_result[] returns

参见 Here

我的问题是如何将上面的代码转换为同步的 http 请求？？？？

Simultaneuos HTTP requests in PHP with cURL

Answer 1

创建要与 CURL 一起使用的 URL 数组，并将它们发送到 multiRequest 函数。请参阅文章中的 GET 示例。

因此它最终会为这些 URL 中的每一个创建 CURL 并发出请求。请求后，它会将结果作为 array 返回到 $multi_curl_result 中。然后你可以使用返回的数据。

<?php

// Add multiRequest function here from article

$select_ids = $db->query("SELECT job_id, tids FROM sent_items");
if ($select_ids->num_rows) {
    while($row = $select_ids->fetch_object()) {
        $records[] = $row;
    }
    $select_ids->free();
}

if(!count($records)) {
    echo 'No records';
} else {
    $curls = array();
    foreach ($records as $r) {
        $curls[] = "http://api.mvaayoo.com/apidlvr/APIDlvReport?user=USER ID:PASSWORD&tid=$r->tids&jobid=$r->job_id";
    }

    $multi_curl_result = multiRequest($curls);
}

您可以将 ID 添加到 CURL 作业。然后你可以通过 ID 从结果数组中获取数据。

$curls[$r->job_id] = "http://api.mvaayoo.com/apidlvr/APIDlvReport?user=USER ID:PASSWORD&tid=$r->tids&jobid=$r->job_id";

现在您知道哪些数据属于哪个作业了。例如，如果 job_id 为 10，则此作业的数据位于 $multi_curl_result[10] 中。

关于 multiRequest 函数如何工作的一些评论

multiRequest 函数(source)。

function multiRequest($data, $options = array()) {

  // array of curl handles
  $curly = array();
  // data to be returned
  $result = array();

  // multi handle
  // Allows the processing of multiple cURL handles asynchronously.
  $mh = curl_multi_init();

  // loop through $data and create curl handles
  // then add them to the multi-handle
  foreach ($data as $id => $d) {
    // Create new CURL handle and add it to array
    // $id makes it possible to detect which result belongs to which request
    $curly[$id] = curl_init();

    // If $data item is array, get URL from array, otherwise item should be URL (for GET requests)
    $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;

    // Set regular CURL options
    curl_setopt($curly[$id], CURLOPT_URL,            $url);
    curl_setopt($curly[$id], CURLOPT_HEADER,         0);
    curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);

    // If $data item is array, then we could have POST data
    if (is_array($d)) {
      // If item has POST data
      if (!empty($d['post'])) {
        // Set POST data
        curl_setopt($curly[$id], CURLOPT_POST,       1);
        curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
      }
    }

    // Set extra CURL options from array
    if (!empty($options)) {
      curl_setopt_array($curly[$id], $options);
    }

    // Add normal CURL handle to a CURL multi handle
    curl_multi_add_handle($mh, $curly[$id]);
  }

  // execute the handles
  // $running will have value, if CURL is still running
  // Every execute will change it, until all requests has been done
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);

  // Add request responses to array
  // Recognizable by $id
  foreach($curly as $id => $c) {
    // Return the content
    $result[$id] = curl_multi_getcontent($c);

    // Removes CURL handle ($c) from multi handle ($mh)
    curl_multi_remove_handle($mh, $c);
  }

  // All done
  curl_multi_close($mh);

  return $result;
}
