直接从 URL 下载文件到本地文件夹或远程服务器中的文件夹

Question

我已经从 link 下载了一个文件并且必须保存在我的本地系统文件夹或远程服务器文件夹中。场景是：我有一个 mailgun 域，当我向它发送邮件时，Mailgun 存储功能 (store()) 将它与所有附件一起存储并通知我。来自 mailgun 的响应在 catch_email_attachment() 中被捕获，我能够获取响应并获得附件的 link。当我直接在浏览器中运行 link 时，它会给我附件，没问题。但我需要下载 catch_email_attachment() 中的文件并将其保存在文件夹中。

可下载文件为：“https://API:<API-KEY>@api.mailgun.net/v2/domains/sandboxa6e6ebce3f68475aa3xxxxxxxd60.mailgun.org/messages/eyJwIjogZmFsc2UsICJrIjogImQ0MmZjxxxxxxxxxxxxxxDQwNy1iYzhlLTA2OWMxY2U3MDg2NCIsIxxxxxxxxxxxxxx1Y2UiLCAiYyI6ICJpYWR0cmFpbGVycyJ9/attachments/0”

我的代码如下：

public function catch_email_attachment()
{
    $data = $this->input->post(null, true);
    if (!empty($data)) {
        if (isset($data['attachments'])) {
            /*
            Output of $data['attachments'] is below:
            [{"url": "https://api.mailgun.net/v2/domains/sandboxa6e6ebce3f68475aa3xxxxxxxd60.mailgun.org/messages/eyJwIjogZmFsc2UsICJrIjogImQ0MmZjxxxxxxxxxxxxxxDQwNy1iYzhlLTA2OWMxY2U3MDg2NCIsIxxxxxxxxxxxxxx1Y2UiLCAiYyI6ICJpYWR0cmFpbGVycyJ9/attachments/0", "content-type": "image/jpeg", "name": "xxxxxxx.jpeg", "size": 9498}]
            */

            copy('https://API:key-e5ae9afab1fa9xxxxxxxxxxxxxxa95a@api.mailgun.net/v2/domains/sandboxa6e6ebce3f68475axxxxxxxxxxxxxxxxxxxxxxxxxxxx.mailgun.org/messages/eyJwIjogZmFsc2UxxxxxxxxxxxxxxxxxxxxxxxxxxxxmUtNDQwNy1iYzhlLTA2OWMxY2U3MDg2NCIxxxxxxxxxxxxxxxxxxxxxxxxxxxx1Y2UiLCAiYyI6ICJpYWR0cmFpbGVycyJ9/attachments/0', '/var/www/download_loc/');
        }
    }
}

我已经提到：

你能帮我解决这个问题吗...在此先感谢。

看起来 $data['attachments'] 是一个 json 数组，所以您需要这样的东西：

    $attachments = json_decode($data['attachments']);
        $api_key = 'APIKEY';
        if ($attachments) {
            foreach ($attachments as $attachment) {

                $context = stream_context_create(array(
                    'http' => array(
                        'header'  => "Authorization: Basic " . base64_encode("API:$api_key")
                    )
                ));

                file_put_contents('/var/www/download_loc/' . $attachment->name, file_get_contents($attachment->url, false, $context));

            }
        }

以上回答对我很有帮助url。我所做的和得到的是：

Mailgun 将响应我们在 maingun 域中设置的钩子函数。捕获来自 Mailgun 的响应：

$data = $this->input->post(null, true);
$attachments = json_decode($data['attachments']);
$apikey = 'API:<API_KEY>@';
foreach ($attachments as $attachment) {
    $st = strpos($attachment->url, 'https://');
    if ($st !== false) {
        $attachment->url = str_replace('https://', 'https://'.$apikey, $attachment->url);
        $temp_name = $attachment->name;
        $file_path = '<PATH_TO_DOWNLOAD>'.$temp_name;
        copy($attachment->url, $file_path); // Downloading file to our path
    }
}

您必须检查来自 Mailgun 响应的端点。并且，必须设置各自的输入或代码。此外，我们必须设置 API KEY & PATH TO DOWNLOAD.

Mailgun 的存储 link 将超过 "api.mailgun.net" "xx.api.mailgun.net"。它将像 "si.api.mailgun.net"、"so.api.mailgun.net"、"se.api.mailgun.net"、"sw.api.mailgun.net" 等。获取附件数据的 URL 将是

例如：https://API:key-60mvxxxxxxxxxxxxxxxx@sw.api.mailgun.net/v3/domains/YOUR_MAILGUN_DOMAIN/messages/xxxxxxxxxxxxxxxxxxxxxxxxxxx=/attachments/0

从 API 编辑的数据 return 将 return URL 获取存储的消息: (项目 > 附件 > url)
