Hello, I am working on a project for a client and have a PHP script that downloads an attachment from Yahoo! Mail. I have the OAuth working correctly (resolved those issues on Sunday) and get a mid via ListMessages. The mid that is used has 2 attachment (the first is a PDF) and has a pid of 2. When I use a URL with the OAuth and no references to the message, folder, or part, I get a valid header response, see below:

http://mail.yahooapis.com/ya/download/?oau...th_signature=...

Array
(
[0] => HTTP/1.0 500 unable_to_get_message_info_or_part

[Content-Type] => text/html; charset=utf-8
[Cache-Control] => private

However, once I add a valid mid, folder, and type, then I get a 404 (Not Found) error:

http://mail.yahooapis.com/ya/download/?oau...=0&inline=0

If someone could point me in the right direction as to what I am doing wrong it would be appreciated.


Thank you.

Hi,

Can you please add the entire request and response headers of a valid oauth session? These are the list of error codes. The first url pasted below says " 500 unable_to_get_message_info_or_part" which I believe has something to do with the download params and its values. The rest of the 404s is not related to download but with auth stuff.

The req should be a GET and have &mid=1_6954_AMvJjkQAAJJjTQgZpgDJg1E/Jsk&fid=Inbox&pid=2&tnef=0&clean=0&inline=0.

Okay, I can't say that Yahoo! has been much help on resolving this issue nor is their documentation adequate to help developers who have issues or problems with downloading or uploading an attachment but I finally have gotten it work successfully. Below is an example of the code in PHP for others that have been struggling to get it work:

$request = new OAuthRequest('GET', "http://mail.yahooapis.com/ya/download/?mid=$mid&fid=Inbox&pid=2&clean=0&inline=0", array(
'oauth_consumer_key'=>$OAuthConsumerKey,
'oauth_nonce'=>mt_rand(),
'oauth_signature_method'=>'HMAC-SHA1',
'oauth_timestamp'=>time(),
'oauth_token'=>$oauth_token,
'oauth_version'=>'1.0',
'oauth_callback'=>'oob'));
$request->sign_request($signature, new OAuthConsumer('', $OAuthConsumerSecret), new OAuthToken('', $oauth_token_secret));
$oauthURL = $request->to_url();

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $oauthURL);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$header = curl_exec($ch);
curl_close($ch);

___________________

If you get the contents of $header, it will contain the downloaded attachment.

The OAuth library and above functions come from the phpsample code that can be downloaded after going to this URL: http://developer.yahoo.com/mail/docs/user_...ialTheUser.html

Hopefully the above can be useful to someone who has not gotten a response from Yahoo!, couldn't find anything online while doing a search, or in the forums.
