Question

我的网络应用需要制作7个不同的soap wsdl api请求来完成一项任务（我需要用户等待所有请求的结果）。每个请求的平均响应时间为500毫秒到1.7秒。我需要并行运行所有这些请求以加快进程。最好的方法是什么：

pthreads或
齿轮工人
fork process
curl multi（我必须构建xml soap body）

Answer 1

首先要说的是，在直接响应Web请求时创建线程绝不是一个好主意，想一想实际扩展到多远。

如果为每个出现的人创建7个线程并且有100个人出现，那么你会要求你的硬件同时执行700个线程，这真的要求很多......

但是，可伸缩性不是我可以帮助你的东西，所以我只是回答这个问题。

<?php
/* the first service I could find that worked without authorization */
define("WSDL", "http://www.webservicex.net/uklocation.asmx?WSDL");

class CountyData {

    /* this works around simplexmlelements being unsafe (and shit) */
    public function __construct(SimpleXMLElement $element) {
        $this->town = (string)$element->Town;
        $this->code = (string)$element->PostCode;
    }

    public function run(){}

    protected $town;
    protected $code;
}

class GetCountyData extends Thread {

    public function __construct($county) {
        $this->county = $county;
    }

    public function run() {
        $soap = new SoapClient(WSDL);

        $result = $soap->getUkLocationByCounty(array(
            "County" => $this->county
        ));

        foreach (simplexml_load_string(
                    $result->GetUKLocationByCountyResult) as $element) {
            $this[] = new CountyData($element);
        }
    }

    protected $county;
}

$threads  = [];
$thread   = 0;
$threaded = true; # change to false to test without threading

$counties = [     # will create as many threads as there are counties
    "Buckinghamshire",
    "Berkshire",
    "Yorkshire",
    "London",
    "Kent",
    "Sussex",
    "Essex"
];

while ($thread < count($counties)) {
    $threads[$thread] = 
        new GetCountyData($counties[$thread]);
    if ($threaded) {
        $threads[$thread]->start();
    } else $threads[$thread]->run();

    $thread++;
}

if ($threaded)
    foreach ($threads as $thread)
        $thread->join();

foreach ($threads as $county => $data) {
    printf(
        "Data for %s %d\n", $counties[$county], count($data));
}
?>

请注意，SoapClient实例不是，也不能共享，这可能会让你失望，你可能想要启用wsdl的缓存......

最快或最强大的方法，可以并行制作7个soap api请求
