Question

我一直面临这个问题，我有4个api来处理并输出到最终的网页。当我这样做时，我的网页加载时间超过一分钟。经过长时间的思考，我发现我正在同时打电话。我需要异步调用以避免延迟。然后我最终得到了这里没有返回网页上任何数据的代码。帮帮我！。我从http://php.net/manual/en/function.curl-multi-exec.php获得了此代码

    // set URL and other appropriate options
    curl_setopt($ch1, CURLOPT_URL, "http://example1.com");
    curl_setopt($ch1, CURLOPT_POST, 1);
    curl_setopt($ch1, CURLOPT_POSTFIELDS,"x=a&y=b");
    curl_setopt($ch1, CURLOPT_HEADER, 0);
    curl_setopt($ch2, CURLOPT_URL, "http://www.example2.com"."m=c&n=d");
    curl_setopt($ch2, CURLOPT_HEADER, 0);
    curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);

    //create the multiple cURL handle
    $mh = curl_multi_init();

    //add the two handles
    curl_multi_add_handle($mh,$ch1);
    curl_multi_add_handle($mh,$ch2);

    $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);

        echo $mrc;


    ?>

我有4个api，其中2个是POST请求，2个是GET。提前致谢

如何使用curl multi asynchonously调用api
