我正在尝试在wordpress上自动下载一个文件(在这种情况下是PDF发票)。
我首先尝试使用wp_remote_get下载它，这似乎很简单，但没有成功(没有文件下载):
function download_pdf_invoice__on_order_completed( $order_id, $order ) {
wp_remote_get( "http://www.africau.edu/images/default/sample.pdf" );
}
add_action( 'woocommerce_order_status_completed', 'download_pdf_invoice__on_order_completed', 20, 2 );
到目前为止，我已经设法使它的工作和下载任何文件cURL只要扩展是在URL，但我不能让它与我的动态下载URL工作，这是这个测试/演示URL:https://www.moloni.com/downloads/index.php?action=getDownload& h = b75b2d99c08c56480da0c5dff4900b4a& d = 189279574, e = teste@moloni.com& i = 1, t = n
function action_woocommerce_admin_order_get_invoice_pdf($url){
//The resource that we want to download.
$fileUrl = 'https://www.moloni.com/downloads/index.php?action=getDownload&h=b75b2d99c08c56480da0c5dff4900b4a&d=189279574&e=teste@moloni.com&i=1&t=n';
//The path & filename to save to.
$saveTo = '/myserver/public_html/wp-content/plugins/my-custom-functionality-master/logo.jpg';
//Open file handler.
$fp = fopen($saveTo, 'w+');
//If $fp is FALSE, something went wrong.
if($fp === false){
throw new Exception('Could not open: ' . $saveTo);
}
//Create a cURL handle.
$ch = curl_init($fileUrl);
//Pass our file handle to cURL.
curl_setopt($ch, CURLOPT_FILE, $fp);
//Timeout if the file doesn't download after 20 seconds.
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
//Execute the request.
curl_exec($ch);
//Get the HTTP status code.
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
//Close the cURL handler.
curl_close($ch);
}
add_action( 'woocommerce_order_status_completed', 'action_woocommerce_admin_order_get_invoice_pdf', 20, 2 );
但是，如果我将$fileUrl替换为这个示例PDF http://www.africau.edu/images/default/sample.pdf，那么它将工作
我考虑过实现某种错误/日志，以便能够看到代码可能引起的错误，但我还没有弄清楚如何在这些情况下将下载链接到woocommerce订单完成的操作
使用file_get_contents从URL下载文件
$fileUrl = 'https://www.moloni.com';
$saveTo = ABSPATH . '/wp-content/plugins/my-custom-functionality-master/logo.jpg'
file_put_contents(
$saveTo,
file_get_contents($fileUrl)
);
