Swoole 4.4：支持 CURL 协程化

栏目: PHP · 发布时间: 6年前

内容简介：在经过验证使用

在 4.4 之前的版本中， Swoole 一直不支持 CURL 协程化，在代码中无法使用 curl 。由于 curl 使用了 libcurl 库实现，无法直接 hook 它的 socket ， 4.4 版本使用 Swoole\Coroutine\Http\Client 模拟实现了 curl 的 API ，并在底层替换了 curl_init 等函数的 C Handler 。

提示

  • CURL Hook 的特性尚处于试验阶段，请勿在生产环境中直接使用
  • 暂不支持文件上传、 CURL Multi
  • 仍然需要依赖 curl ，请务必安装 curl 扩展

支持的特性列表

  • GET/POST
  • Header
  • Cookie
  • Https

经过验证 Guzzle CURL 完全可以使用

开启

使用 Runtime::enableCoroutine 来开启 CURL Hook 。

默认不开启 CURL Hook 

Swoole\Runtime::enableCoroutine(SWOOLE_HOOK_ALL);
Swoole\Runtime::enableCoroutine(SWOOLE_HOOK_CURL);

使用

$n = 10;
while($n--) {
    go(function () {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "http://www.xinhuanet.com/");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        $output = curl_exec($ch);
        if ($output === FALSE) {
            echo "CURL Error:" . curl_error($ch);
        }
        curl_close($ch);
        echo strlen($output) . " bytes\n";
    });
}

要将上面两段代码合并到一个文件中执行

运行结果

可以看到整个程序是并行的，进程没有任何阻塞。

strace 跟踪

使用 strace 跟踪发现，所有系统调用均变成 epoll + socket 的异步非阻塞调用了。
