我需要从 PHP 脚本调用网络服务。 Web 服务很慢,我对其响应不感兴趣,我只想向它发送数据。
我正在尝试使用 curl_multi_exec(下面是一个示例:http://www.jaisenmathai.com/articles/php-curl-asynchronous.html),它的第二个参数($still_running)让您知道它何时完成发送和接收。但是,同样,我只想知道我的脚本何时发送完毕。当然,如果我在脚本发送完数据之前退出脚本,Web 服务就不会注册接收请求。
另一种查看方式是检测 PHP 何时空闲,等待服务器响应。
我想实现的是这个对话:
- PHP:您好,请保存此数据
- WS:好的,呵呵,让我们考虑一下。
- PHP:是啊! (去做更重要的事情)
- WS:好的,我处理完了,这是您的回复……PHP?你去哪儿?我觉得习惯了:(
最佳答案
你可以试试
$url = "http://localhost/server.php";
$nodes = array();
$nodes["A"] = array("data" => mt_rand()); <-------- Random Data
$nodes["B"] = array("data" => mt_rand());
$nodes["C"] = array("data" => mt_rand());
$nodes["D"] = array("data" => mt_rand());
echo "<pre>";
$mh = curl_multi_init();
$curl_array = array();
foreach ( $nodes as $i => $data ) {
$curl_array[$i] = curl_init($url);
curl_setopt($curl_array[$i], CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_array[$i], CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)');
curl_setopt($curl_array[$i], CURLOPT_POST, true);
curl_setopt($curl_array[$i], CURLOPT_POSTFIELDS, $data);
curl_setopt($curl_array[$i], CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($curl_array[$i], CURLOPT_TIMEOUT, 15);
curl_multi_add_handle($mh, $curl_array[$i]);
echo "Please save this data No : $i ", $data['data'], PHP_EOL;
}
echo PHP_EOL ,PHP_EOL;
$running = NULL;
do {
usleep(10000);
curl_multi_exec($mh, $running);
} while ( $running > 0 );
$res = array();
foreach ( $nodes as $i => $url ) {
$curlErrorCode = curl_errno($curl_array[$i]);
if ($curlErrorCode === 0) {
$info = curl_getinfo($curl_array[$i]);
if ($info['http_code'] == 200) { <------- Connection OK
echo "Cya! (off to do something more important No : $i Done", PHP_EOL;
echo curl_multi_getcontent($curl_array[$i]) , PHP_EOL ;
}
}
curl_multi_remove_handle($mh, $curl_array[$i]);
curl_close($curl_array[$i]);
}
curl_multi_close($mh);
输出
Please save this data No : A 1130087324
Please save this data No : B 1780371600
Please save this data No : C 764866719
Please save this data No : D 2042666801

Ok, Im done processing, here is your response...
{"data":"1130087324"} PHP? Where did you go?
I feel used :(

简单测试服务器 server.php
echo printf("Ok, Im done processing, here is your response... \n\t%s PHP? Where did you go? \n\tI feel used :(\n", json_encode($_REQUEST));
