I need some help formulating an IMAP fetch command to only fetch a certain mime attachment without fetching the whole body or other attachment. Given the following bodystructure
(BODYSTRUCTURE (("text" "html" ("charset" "utf-8") NIL NIL "base64" 568 8 NIL NIL NIL) "mixed" ("boundary" "===============0621936444==") NIL NIL))
how would a fetch command for fetching the text/html part look like?
I have read Section 6.4.5 of RFC3501 several times but I still don't get it. Any pointers to further examples of fetch requests for mime attachments would also be appreciated.
Off the top of my head it would be something like:
FETCH 88 BODY.PEEK[1]
where 88 is the 88th message, and 1 is the body part.
Try this one:
FETCH uid BODY.PEEK[1.2]
UID FETCH uid_of_the_mail BODY[1.2] is the first inline attachment. Well, for gmail, 1 for TEXT, 2-N for attachment. 1.1 for TEXT， 1.2 should for the first inline attachment, 1.N-1 should for the Nth inline attachment.
First of all you need to parse bodystructure response and then find each part section string, Once you have acheived each part section string then You can fetch required part mime.
Assume that You need to fetch first part mime then command should be like this
. FETCH msgno (BODY[1.MIME])

I use graph api to create a message with attachment(s).
All runs fine but the server send back the complete message in response, including the attachments.
Is there a way to only get the message id in the response ?
I try with :
string webApiUrl = $"{_apiUrl}v1.0/users/{senderId}/messages?$select=id"
but I still get the whole message with 98ko of attachment.
You can do it using the prefer:return=minimal header in the request which will mean you will just get a 204 response. However the id of the item that was created will be returned in the location header (the response should really have the OData-EntityId if they are following the oData spec to the letter, also I'm not sure why it return the Outlook v2 location rather then the graph but the message Id is the same between them)
I have a url I want to get using google scripts' UrlFetchApp.fetch( ) command. Unfortunately this url has a | (gets partially encoded into %7c) in it and every time i try to fetch it I get an error saying 'invalid argument'. Any idea how to get around this issue and successfully fetch the url?
It seems to work if the url passed to UrlFetchApp.fetch is already encoded.
Let's say you want to fetch www.google.com/aaa|bbb (which doesn't really exist). The following script fails with "invalid argument":
UrlFetchApp.fetch("www.google.com/aaa|bbb");
But this one correctly returns a 404 as the request is valid but the page is not found:
UrlFetchApp.fetch("www.google.com/aaa%7Cbbb");
If that doesn't help, it would help if you could paste your url.
We have a function in our Rails code that accepts a JSON POST body:
contacts = ActiveSupport::JSON.decode(request.raw_post.gsub("+", ""))
(I'm aware that I can get this from params["_json"] as well, but we have extremely large (MBs) POST bodies that do not get put into params["_json"] for some reason (and + throws errors too).
Since the JSON is usually sent from a mobile client, it's important to us to optimize the upload size. We want to switch to having the POST body gzipped.
However, no matter what we do, we get the same error with no line number:
MultiJson::DecodeError (743: unexpected token at ''):
We have tried:
gzipped_contacts = Zlib::GzipReader.new(StringIO.new(request.raw_post)).read
contacts = ActiveSupport::JSON.decode(gzipped_contacts.gsub("+", ""))
This:
gzipped_contacts = ActiveSupport::Gzip.decompress(request.raw_post)
contacts = ActiveSupport::JSON.decode(gzipped_contacts.gsub("+", ""))
And the solution found here: Rails: how to unzip a compressed xml request body?
I'm pretty sure this is not occurring at the controller level because I can't log anything there, so it needs to be done in the middleware or at the server (but I can't find anything for Nginx that lets us deflate). Please assist!
Ok, turns out the iPhone client was sending the wrong headers. So the solution for anyone encountering this is to see the advice here:

And verify that you are sending Content-Type: gzip/json.
I am working on a mail client using IMAP and I am looking for the command for receiving the attachments of a message.
All message info is retrieved using the FETCH command. You have two options on how to use it, however.
First, you can retrieve the entire email message, verbatim. In that case, you're going to need to include a MIME parser in your client to figure out the structure of the message. (Each platform has at least one or two popular MIME parsers; since you haven't told us what you're coding in, I can't recommend one for you.) Once you get the message structure from your MIME parser, you'll need some client logic to determine which parts are attachments. It's worth looking at RFC 2183 to get you started. In general, parts with a Content-Disposition starting with "attachment" are going to be attachments, but all mail client authors go through a phase of trial and error getting it right. In order to download the entire email message, you'd issue the IMAP command
$ UID FETCH <uid> BODY.PEEK[]
Second, you can have the IMAP server parse the message structure for you by issuing a FETCH BODYSTRUCTURE (note: no square brackets). You'll have to parse the returned BODYSTRUCTURE data yourself; the IMAP RFC explains the format and gives a few examples.
# message, no attachments:
("TEXT" "PLAIN" ("CHARSET" "ISO-8859-1" "FORMAT" "flowed") NIL NIL "7BIT" 1469 50 NIL NIL NIL NIL)
# message, one attachment
(("TEXT" "PLAIN" ("CHARSET" "US-ASCII") NIL NIL "QUOTED-PRINTABLE" 56 1 NIL NIL NIL NIL)("AUDIO" "X-WAV" ("NAME" "voicemail.wav") NIL NIL "BASE64" 152364 NIL ("attachment" ("FILENAME" "voicemail.wav")) NIL NIL) "MIXED" ("BOUNDARY" "----_=_NextPart_001_01C4ACB3.5AA7B8E2") NIL NIL NIL)
Once you've determined which parts you're interested in, you can issue a FETCH for the displayable message body. Your client can then just list the message attachments (parsed out of the BODY response) and can then go back and FETCH them if the user clicks on them. So the IMAP commands you'd be issuing would be along the lines of:
$ UID FETCH <uid> (BODY ENVELOPE) # get structure and header info
$ UID FETCH <uid> (BODY[1]) # retrieving displayable body
$ UID FETCH <uid> (BODY[2]) # retrieving attachment on demand
I believe what you are looking for is the IMAP v4 FETCH command.
You could use Context.IO's files resource to quickly and easily fetch attachments.

i'm working with a server which response using the JSON format.
when the request contain valid data they respond with a string like this
{"data":{"results":[{"Branch":"ACCT590006"}]}}
but if the parameters of the request are incorrect the response goes like this
{"error":{"errors":[{"domain":"global","reason":"invalid","message":"Invalid
Params"}],"code":98865,"message":"Invalid
param value"}}
So the questions are how i can determine when the response of the server contains a error string using the TJSONObject object and additionally parse the JSON string to show the messages and error codes like this.
Failed reason : invalid
Message : Invalid params
Code: 98865
message : invalid param value.
I've worked a little with JSON, an every time I've parsed from code(delphi 7). But i've searched a little bit, and here you may find the answer of your question:
http://edn.embarcadero.com/print/40882
and with a little adaption this should work.
Best regards,
