问题描述
我正在用PHP执行两个curl请求.它们是这样的:
I'm executing two curl post requests in PHP. Here's how they look like:
//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，但是有时，第二个curl post请求未执行.
They are working, but sometimes, the second curl post request is not executed.
我想同时执行这两个请求.
I'd like to execute this two requests at the same time.
我该怎么做?请注意，他们在邮场中采用了不同的选择.
How can I do that? Please note that they take different options in the postfields.
感谢您的帮助！
推荐答案
因此，您要做的是异步执行cUrl请求.
So what you want to do is asynchronous execution of the cUrl Requests.
因此，您将需要一个用于php的异步/并行处理库.
So you would need a asynchronous/parallel processing library for php.
您需要首先获取dll/so文件并将其保存在php/ext目录中，然后在php.ini中启用该扩展名.
You would need to first get the dll/so file and save it in the php/ext dir, and enable that extension in php.ini.
之后，此代码将完成您的工作:
After That, this code would do your job:
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();
$req2->start();
因此，基本上，您需要创建一个扩展Thread类的类，并且要异步运行(而是并行运行)的所有内容都将放入该类的函数run()中.
So, basically you need to create a class which extends the Thread class and everything you want to run asynchronously (rather parallely), would be put in the function run() of the class.
当您要启动线程时，只需在变量中实例化类，然后调用对象的start方法，例如$threadsObject->start()，并且run()中的所有内容都将在另一个线程上执行.
When you want to start the thread just instantiate the class in a variable, and call the start method of the object, like $threadsObject->start() and everything in the run() would be executed on another thread.
参考:
就是这样.
另一种方法是使用内置的异步cURL函数.
The other way is to use the built in asynchronous cURL functions.
因此，当使用curl_multi_*时，您的代码应类似于:
So, when using curl_multi_*, your code would look something like:
$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);
