He estado tratando de encontrar información sobre cómo recuperar archivos adjuntos desde una cuenta de Gmail en python o PHP, espero que alguien aquí pueda ser de alguna ayuda, gracias.Obteniendo archivos adjuntos de gmail a través de python o php

Usted tendrá que habilitar el acceso IMAP en su cuenta de Gmail (Configuración → Reenvío y correo POP/IMAP) y, a continuación, utilizar imaplib.IMAP4_SSL para acceder a ella.
Utilice el texto sin formato de cada mensaje como argumento en email.message_from_string para procesar cualquier archivo adjunto.
Los documentos PHP para imap_open explican la conexión a Gmail en los comentarios (por ejemplo, 31-Oct-2007 07:50):
$mbox = imap_open("{imap.gmail.com:993/imap/ssl}INBOX", "[email protected]", "password") or die("can't connect: " . imap_last_error());
Cuando, obviamente, tiene que rellenar el nombre de usuario actual y contraseña según sea apropiado, y luego para identificar los archivos adjuntos en las partes del correo electrónico se siguen las instrucciones de: http://www.electrictoolbox.com/extract-attachments-email-php-imap/
lo que, resumiendo, dice que utilice:
// in a for($i=1;$i<$nummsgs;$i++) loop over all the messages in the inbox $structure = imap_fetchstructure($mbox, $i);
para identificar los archivos adjuntos en la estructura. Sin embargo, ese es un proceso bastante elaborado de deconstrucción de mensajes MIME (que tienen mucha variabilidad opcional que debe tenerse en cuenta), por lo que los fundamentos/esquema de una función están en esa página de electrictoolbox.
¡Encontré un código que funciona! esto descargará los archivos adjuntos a una carpeta seleccionada
<?php
$gmail_username = '[email protected]';
$gmail_password = 'mypassword';
$imap = imap_open ("{imap.gmail.com:993/imap/ssl}INBOX", $gmail_username, $gmail_password) or die("can't connect: " . imap_last_error());
$savefilepath = 'path/to/images_folder/'; //absolute path to images directory
$imagefilepath = 'images/'; //relative path to images directory
$headers = imap_headers($imap);
foreach ($headers as $mail) {
$flags = substr($mail, 0, 4);
//Check for unread msgs, get their UID, and queue them up
if (strpos($flags, "U")) {
preg_match('/[0-9]+/',$mail,$match);
$new_msg[] = implode('',$match);
}
}
if ($new_msg) {
foreach ($new_msg as $result) {
$structure = imap_fetchstructure($imap,$result);
$parts = $structure->parts;
foreach ($parts as $part) {
if ($part->parameters[0]->attribute == "NAME") {
//Generate a filename with format DATE_RANDOM#_ATTACHMENTNAME.EXT
$savefilename = date("m-d-Y") . '_' . mt_rand(rand(), 6) . '_' . $part->parameters[0]->value;
save_attachment(imap_fetchbody($imap,$result,2),$savefilename,$savefilepath,$savethumbpath);
imap_fetchbody($imap,$result,2); //This marks message as read
}
}
}
}
imap_close($imap);
function save_attachment($content , $filename , $localfilepath, $thumbfilepath) {
if (imap_base64($content) != FALSE) {
$file = fopen($localfilepath.$filename, 'w');
fwrite($file, imap_base64($content));
fclose($file);
}
}
?>
Tomé el código anterior y lo arreglé y lo probé. Funciona con PHP5.
<?php
$gmail_username = '[email protected]';
$gmail_password = 'password';
$imap = imap_open ("{imap.gmail.com:993/imap/ssl}INBOX", $gmail_username, $gmail_password) or die("can't connect: " . imap_last_error());
$savefilepath = '//Server/share/Local/Pathname/'; //absolute path to images directory
$imagefilepath = '/Local/Pathname/'; //relative path to images directory
$savethumbpath = '/Local/Pathname/'; //relative path to images directory
$headers = imap_headers($imap);
foreach ($headers as $mail) {
$flags = substr($mail, 0, 4);
//Check for unread msgs, get their UID, and queue them up
if (strpos($flags, "U")) {
preg_match('/[0-9]+/',$mail,$match);
$new_msg[] = implode('',$match);
}
}
if ($new_msg) {
foreach ($new_msg as $result) {
$structure = imap_fetchstructure($imap,$result);
$parts = $structure->parts;

if ($part->parameters[0]->attribute == "NAME") {
//Generate a filename with format DATE_RANDOM#_ATTACHMENTNAME.EXT
$savefilename = date("m-d-Y") . '_' . rand() . '_' . $part->parameters[0]->value;
save_attachment(imap_fetchbody($imap,$result,2),$savefilename,$savefilepath,$savethumbpath);
imap_fetchbody($imap,$result,2); //This marks message as read
}
}
}
}

I recently worked on this topic and here is the code which works well. It also saves the details of the attachments in a word document with the following details:
-> Date
-> Time
-> From
-> Email ID
-> Subject
