php - PHP 中的异步curl 请求

Question

我正在 PHP 中执行两个curl post 请求。它们的外观如下:

//Onfleet API credentials 
$username = 'xxxxx'; 
$api_onfleet = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';    
$url_onfleet = "https://onfleet.com/api/v2/tasks";

curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
    $request =  $url.'api/mail.send.json';

    // Generate curl request
    $session = curl_init($request);
    // Tell curl to use HTTP POST
    curl_setopt ($session, CURLOPT_POST, true);
    // Tell curl that this is the body of the POST
    curl_setopt ($session, CURLOPT_POSTFIELDS, $params);
    // Tell curl not to return headers, but do return the response
    curl_setopt($session, CURLOPT_HEADER, false);
    curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

    // obtain response
    $response = curl_exec($session);
    curl_close($session);


     // Post the Pickup task to Onfleet
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url_onfleet);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_USERPWD, $api_onfleet);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_ENCODING, "");  
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, '{"destination":{"address":{"unparsed":"'.$pickup_address.'"},"notes":"'.$comments.'"},"recipients":[{"name":"'.$name.'","phone":"+61'.$phone.'","notes":"Number of riders: '.$riders.'"}],"completeBefore":'.$timestamp.',"pickupTask":"yes","autoAssign":{"mode":"distance"}}');

    $result_pickup = curl_exec($ch);
    curl_close($ch);

    // Post the Dropoff task to Onfleet
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url_onfleet);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_USERPWD, $api_onfleet);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_ENCODING, "");  
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, '{"destination":{"address":{"unparsed":"'.$dropoff_address.'"},"notes":"'.$comments.'"},"recipients":[{"name":"'.$name.'","phone":"+61'.$phone.'","notes":"Number of riders: '.$riders.'"}],"autoAssign":{"mode":"distance"}}');

    $result_dropoff = curl_exec($curl);
    curl_close($curl);

它们正在工作，但有时，第二个curl post请求未执行。

我想同时执行这两个请求。

我怎样才能做到这一点？请注意，他们在帖子字段中采用不同的选项。

感谢您的帮助!

Answer 1

所以您想要做的是异步执行 cUrl 请求。

所以你需要一个 php 的异步/并行处理库。

<小时/>

异步 cURL

另一种方法是使用内置的 asynchronous cURL functions .

所以，当使用curl_multi_*时，您的代码将类似于:

$username = 'xxxxx'; 
$api_onfleet = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';    
$url_onfleet = "https://onfleet.com/api/v2/tasks";

curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
    $request =  $url.'api/mail.send.json';

    // Generate curl request
    $session = curl_init($request);
    // Tell curl to use HTTP POST
    curl_setopt ($session, CURLOPT_POST, true);
    // Tell curl that this is the body of the POST
    curl_setopt ($session, CURLOPT_POSTFIELDS, $params);
    // Tell curl not to return headers, but do return the response
    curl_setopt($session, CURLOPT_HEADER, false);
    curl_setopt($session, CURLOPT_RETURNTRANSFER, true);


     // Post the Pickup task to Onfleet
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url_onfleet);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_USERPWD, $api_onfleet);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_ENCODING, "");  
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, '{"destination":{"address":{"unparsed":"'.$pickup_address.'"},"notes":"'.$comments.'"},"recipients":[{"name":"'.$name.'","phone":"+61'.$phone.'","notes":"Number of riders: '.$riders.'"}],"completeBefore":'.$timestamp.',"pickupTask":"yes","autoAssign":{"mode":"distance"}}');
$mh = curl_multi_init();
curl_multi_add_handle($mh,$session);
curl_multi_add_handle($mh,$ch);

$active = null;
//execute the handles
do {
    $mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
    if (curl_multi_select($mh) != -1) {
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);
    }
}
//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);

建议阅读:

1. curl_multi_init()
2. curl_multi_exec()
3. curl_multi_add_handle()
4. curl_multi_remove_handle()

pThreads

PHP 的著名线程库之一是 pthreads

您需要首先获取 dll/so 文件并将其保存在 php/ext 中dir，并在 php.ini 中启用该扩展.

之后，这段代码就可以完成你的工作:

class Request1 extends Thread {
    $username = 'xxxxx'; 
    $api_onfleet = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';    
    $url_onfleet = "https://onfleet.com/api/v2/tasks";
    public function run() {
        curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
        $request =  $this->url.'api/mail.send.json';
    
        // Generate curl request
        $session = curl_init($request);
        // Tell curl to use HTTP POST
        curl_setopt ($session, CURLOPT_POST, true);
       // Tell curl that this is the body of the POST
       curl_setopt ($session, CURLOPT_POSTFIELDS, $params);
       // Tell curl not to return headers, but do return the response
       curl_setopt($session, CURLOPT_HEADER, false);
       curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

        // obtain response
        $response = curl_exec($session);
        curl_close($session);
    }
}


class Request2 extends Thread {
    $username = 'xxxxx'; 
    $api_onfleet = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';    
    $url_onfleet = "https://onfleet.com/api/v2/tasks";
    public function run() {
      $ch = curl_init();
      curl_setopt($ch, CURLOPT_URL, $url_onfleet);
      curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($ch, CURLOPT_USERPWD, $this->api_onfleet);
      curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
      curl_setopt($ch, CURLOPT_ENCODING, "");  
      curl_setopt($ch, CURLOPT_POST, true);
      curl_setopt($ch, CURLOPT_POSTFIELDS, '{"destination":{"address":{"unparsed":"'.$pickup_address.'"},"notes":"'.$comments.'"},"recipients":[{"name":"'.$name.'","phone":"+61'.$phone.'","notes":"Number of riders: '.$riders.'"}],"completeBefore":'.$timestamp.',"pickupTask":"yes","autoAssign":{"mode":"distance"}}');

      $result_pickup = curl_exec($ch);
      curl_close($ch);

      // Post the Dropoff task to Onfleet
      $curl = curl_init();
      curl_setopt($curl, CURLOPT_URL, $this->url_onfleet);
      curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
      curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($curl, CURLOPT_USERPWD, $this->api_onfleet);
      curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
      curl_setopt($curl, CURLOPT_ENCODING, "");  
      curl_setopt($curl, CURLOPT_POST, true);
      curl_setopt($curl, CURLOPT_POSTFIELDS, '{"destination":{"address":{"unparsed":"'.$dropoff_address.'"},"notes":"'.$comments.'"},"recipients":[{"name":"'.$name.'","phone":"+61'.$phone.'","notes":"Number of riders: '.$riders.'"}],"autoAssign":{"mode":"distance"}}');

      $result_dropoff = curl_exec($curl);
      curl_close($curl);
    }
}

$req1 = new Request1();
$req1->start();
$req2 = new Request2();
$req2->start();

所以，基本上您需要创建一个扩展 Thread 的类类以及您想要异步(而不是并行)运行的所有内容都将放入函数 run() 中类(class)的。

当你想启动线程时，只需在变量中实例化该类，然后调用该对象的start方法，例如$threadsObject->start()以及 run() 中的所有内容将在另一个线程上执行。

引用:

1. class::Thread
2. Thread::start

就是这样。
