Question

在Laravel 5.5和php7上使用curl时，我遇到了一个非常奇怪的问题。当我仅使用单个连接时，此curl函数不会有任何问题：

    function getSslPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_URL, $url);    
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
    }

我试图同时访问带有信息的本地php文件。我在apache上使用VHOST：server.local，文件在该文件夹server.local / request.php中。因此，有了上面的curl函数，它就可以按我期望的那样工作。

问题是，当我必须在另一个函数中使用它来使用curl_multi同时获取多个请求时，这是代码：

    foreach($data as $key => $fetch) {  
        $info[$key]['name'] = $fetch->name;
        $info[$key]['url'] = 'http://server.local/request.php?url='.$fetch->url;
    }

$multi = curl_multi_init();
$channels = array();

foreach ($info as $url) {
    $ch = curl_init();
    //curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    //curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);
    curl_setopt($ch, CURLOPT_URL, $url['url']);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    //curl_setopt($ch, CURLOPT_HTTPGET, 1);
    //curl_setopt($ch, CURLOPT_DNS_USE_GLOBAL_CACHE, false );
    //curl_setopt($ch, CURLOPT_DNS_CACHE_TIMEOUT, 2 );
    //curl_setopt($ch, CURLOPT_PORT, 80);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    //curl_setopt($ch, CURLOPT_REFERER, $url['url']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 5); //timeout in seconds

    curl_multi_add_handle($multi, $ch);

    $channels[$url['url']] = $ch;
}

$active = null;
do {
    $mrc = curl_multi_exec($multi, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
    if (curl_multi_select($multi) == -1) {
        continue;
    }
    do {
        $mrc = curl_multi_exec($multi, $active);
    } while ($mrc == CURLM_CALL_MULTI_PERFORM);
}

$i = 0;
dd($channels);
foreach ($channels as $channel) {
    $info[$i]['data'] = curl_multi_getcontent($channel);
    curl_multi_remove_handle($multi, $channel);
    $i++;
}

curl_multi_close($multi);

因此，我尝试了curl_setopt中带有注释和未注释行的所有组合。没事！它工作的唯一方法是当我将request.php放在主Web目录中，并用127.0.0.1更改server.local时。我什至试图申请可运行的真实网站，但仍然一无所获。

我在dd（$ channels）中收到的代码；是这个吗？

array:1 [▼
  "http://server.local/request.php" => curl resource @276 ▼
    url: "http://server.local/request.php"

    primary_ip: ""
    certinfo: []
    primary_port: 0
    local_ip: ""
    local_port: 0
  }
]

仅出于协议目的，在request.php中，我只有一个Hello World ...该请求正在浏览器负载中甚至在终端curl请求中返回“ Hello World”。我不知道我做错了什么？请帮助：/
