基于 Laravel 6、 Guzzle 6 下载远程文件至服务器磁盘的实现
1、现在正在尝试将远程的 ZIP 文件下载至服务器。 远程文件网址：https://www.shuijingwanwq.com/wp-content/uploads/2021/07/两位老人被两只狗给撞了.wmv
2、参考：https://guzzle-cn.readthedocs.io/zh_CN/latest/request-options.html#sink 。声明响应的主体部分将要保存的位置。如图1
图1
3、参考：https://www.shuijingwanwq.com/2020/11/26/4627/ 。传入 fopen() 返回的资源将响应写入 PHP 流
/**
* 下载 ZIP
* @param string $uri 文件的绝对 URI
* @param string $absolutePath 文件的绝对路径(下载至的目标路径)
* @return void
*/
public function downloadZip($uri, $absolutePath) {
// 实例化 HTTP 客户端
$client = new Client;
// 打开即将下载的本地文件，在该文件上打开一个流
$resource = fopen($absolutePath, 'w');
$client->get($uri, ['sink' => $resource]);
// file_put_contents(storage_path() . '/logs/ZipHandler-downloadZip-absolutePath-' . microtime(true) . '-' . mt_rand() . '.txt', print_r($response, true), FILE_APPEND | LOCK_EX);
// 关闭一个已打开的文件指针
fclose($resource);
}

5、需要先确保目录是存在的。判断目录是否存在，如果不存在，则递归创建。
// 文件的相对路径
$directory = '/theme_downloads/' . date('Y/m/d');
// 判断目录是否存在，如果不存在，则递归创建
if (!file_exists(storage_path('app') . $directory)) {
// file_put_contents(storage_path() . '/logs/ThemeInstallationJob-handle-directory-' . microtime(true) . '-' . mt_rand() . '.txt', print_r($directory, true), FILE_APPEND | LOCK_EX);
Storage::disk('local')->makeDirectory($directory);
}
$uri = 'https://www.shuijingwanwq.com/wp-content/uploads/2022/05/theme-1.zip';
$absolutePath = storage_path('app') . $directory . '/' . microtime(true) . '.' . mt_rand() . '.zip';
// file_put_contents(storage_path() . '/logs/ThemeInstallationJob-handle-absolutePath-' . microtime(true) . '-' . mt_rand() . '.txt', print_r($absolutePath, true), FILE_APPEND | LOCK_EX);
app(ZipHandler::class)->downloadZip($uri, $absolutePath);
6、下载成功。但是如果下载：.zip 的文件，提示：fclose(): supplied resource is not a valid stream resource

7、在尝试关闭资源之前检查资源是否仍然是资源：
// 检测变量是否为资源类型，如果是，则关闭
if (is_resource($resource)) {
fclose($resource);
}
8、最后自行在 Windows 10 中生成一个 zip 文件，再次测试下载，下载成功。如图2
