php单卷发工作,但多卷曲不起作用？

Question

所以我正在使用放大器,然后切换到z-wamp认为它会解决问题,但事实并非如此.

我在我的localhost(localhost/site1和localhost/site2)中有单独的"站点",我正在尝试发送多个curl请求,但由于某些奇怪的原因,它没有做任何事情!它只适用于我对一个站点进行一次卷曲.这有效:

$ch = curl_init('http://localhost/site1/');
curl_setopt_array($ch, array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HEADER => false,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => array('data' => $data)
));
$res = curl_exec($ch);
//yay!

另一方面,这不起作用:

...
//add a bunch of curl sessions
//to $this->sessions
...
$window = 15;
if (count($this->sessions) < $window)
    $window = count($this->sessions);

$mh = curl_multi_init();

$site_map = array();

for ($i = 0; $i < $window; ++$i) {
    curl_multi_add_handle($mh, $this->sessions[$i]);
    $site_map[(string) $this->sessions[$i]] = $i;
}

$data_results = array();
$running = null;

do {
    $execrun = curl_multi_exec($mh, $running);
} while ($execrun === CURLM_CALL_MULTI_PERFORM);

while ($running && $execrun === CURLM_OK) {

    //the loop just keeps going forever from here

    if (curl_multi_select($mh) !== -1) {
        do {
            $execrun = curl_multi_exec($mh, $running);
        } while ($execrun === CURLM_CALL_MULTI_PERFORM);
    }

    if ($execrun !== CURLM_OK)
        break;

    //to here and never enters the loop below

    while ($done = curl_multi_info_read($mh)) {

        $output = curl_multi_getcontent($done['handle']);

        if ($output)
            $data_results[$site_map[(string) $done['handle']]] = $output;
        else
            $data_results[$site_map[(string) $done['handle']]] = null;

        if (isset($this->sessions[$i]) && $i < count($this->sessions)) {
            curl_multi_add_handle($mh, $this->sessions[$i]);
            $site_map[(string) $this->sessions[$i]] = $i;
            ++$i;
        }

        unset($site_map[(string) $done['handle']]);
        curl_multi_remove_handle($mh, $done['handle']);
        curl_close($done['handle']);
    }
}
curl_multi_close($mh);
return $data_results;

所以在上面的多卷曲代码中,它开始运行,将句柄添加到$ mh,一旦执行,它将保持循环并且永远不会进入$ done = curl_multi_info_read($ mh)while循环.与此同时它仍然运行良好,并且$ run一直等于2.此外,curl_multi_info_read将返回false.所以它只是永远循环.

我的curl扩展已启用(显然,如果单个curl工作),以下是来自PHP Info的详细信息:

SSL Version OpenSSL/1.0.0g
ZLib Version    1.2.5
libSSH Version  libssh2/1.3.0

这个东西世界上到底发生了什么？它可能是我的PHP配置的东西？Apache配置？再一次,我正在使用z-wamp.

PHP版本5.3.10 Apache版本2.4.1 Win 7 64位将PHP目录添加到PATH

编辑 事实证明,它一定是某种Apache/PHP配置类型问题,我根本无法发现,因为我放弃了z-wamp并安装了wampserver,这次工作正常.

Answer 1

我刚刚回答了另一个关于多次 curl 调用的问题。

这就是我为运行请求所做的一切。

do {
    $status = curl_multi_exec($mh, $running);
} while ($status === CURLM_CALL_MULTI_PERFORM || $running);

然后我通过遍历我的 curl 处理程序数组来获取我需要的信息。

$returned = array();
foreach ($requests as $identifier => $request) {
    $returned[$identifier] = curl_multi_getcontent($request);
    curl_multi_remove_handle($mh, $request);
    curl_close($request);
}

上述方法对我有用，但是您似乎只想向 curl 多处理程序添加一定数量的会话。我们可能可以将上面的 do-while 循环更改为以下内容：

do {
    $status = curl_multi_exec($mh, $running);
    if ($running < $window) {
        for ($x = 0; $x < $window - $running; $x++) {
            $index = count($site_map) + $x -1;
            curl_multi_add_handle($mh, $this->sessions[$index]);
            $site_map[(string) $this->sessions[$index]] = $index;
        }
    }
} while ($status === CURLM_CALL_MULTI_PERFORM || $running);

之后，我们可以修改数据获取并用while ($running && $execrun === CURLM_OK){}以下内容替换整个部分，因为它只会在处理完所有 curl 调用后运行：

$returned = array();
foreach ($this->sessions as $identifier => $request) {
    $returned[$identifier] = curl_multi_getcontent($request);
    curl_multi_remove_handle($mh, $request);
    curl_close($request);
}
