rfc822 curly brace / gmail in Dsync - gmail

I am now using Dsync, an ipaas.
I want to send a message with gmail from another source(JIRA).
Since Dsync supplies auto curly braces in body, I cannot follow the rfc822 format just like below.
From: example <fromex.gmail.com>
To: exampleto <toex.gmail.com>
subject: subject example
this is plain body. no need attachment function.
instead, Dsync supply them with curly braces like below.
{
From: example <fromex.gmail.com>
To: exampleto <toex.gmail.com>
subject: subject example
this is plain body. no need attachment function.
}
is there any way to send gmail or rfc822 with curly braces?
or with headers.
thanks.

nestjs substitutes symbols in request body

I'm trying to send a request to my Nestjs application, with just plain string in the request body, for example:
test23+Se5+345
Then in my application, I have a middleware, where I need to do something with this string.
The problem is when I access request body in middleware const requestBody = Object.keys(req.body)[0];, this string looks like this:
test23 Se5 345
All of the + symbols are substituted by
I don't have additional convertings before this, and I know that middleware runs first in the request lifecycle. I think maybe there is some issue with body-parser, but I don't know yet how to fix this.
This is because symbol + is treated as space, so before send it, you need to encode your + characters to %2b. More here: How to encode the plus (+) symbol in a URL

Adding message to gmail error "Payload parts count different from expected"

I am adding a message to a gmail folder using this (example) URL:
https://www.googleapis.com/gmail/v1/users/user#domain.com/messages/import?uploadType=multipart
The body of the request looks like this:
--test_abc123
Content-Type: application/json; charset=UTF-8
{
"labelIds": [ "Label_525" ],
"raw": "RnJvbTogIlNlY3RpZ28gQ2VydGlmaWNh..."
}
--test_abc123--
The raw data is a base64 encoded standard MIME message that looks normal to me. The result of this POST is http error 400 with the error response "Payload parts count different from expected 2. Request payload parts count: 1".
I can supply the original MIME text if that is helpful, but let me emphasize that I have been running this code for several years without problem. I've tried different messages to test this out, but it appears that Google has changed something to break my software.
Is Google objecting to my raw data, or something about the MIME encoding? Any ideas what the problem could be?
---- Addendum ----
I have gotten a few messages to work, they seem to all have image or data attachments. However I really don't see any problem with the messages that are failing - I can import them into Office 365 or Thunderbird or anything else and they render just fine. As a test, I tried importing the message below, which was taken from the MIME RFC. It fails with the same error. I think that Google has changed something to make their MIME parser very fussy, but I don't see how I can fix my input data.
From: Nathaniel Borenstein <nsb#bellcore.com>
To: Ned Freed <ned#innosoft.com>
Subject: Sample message
MIME-Version: 1.0
Content-type: multipart/mixed; boundary="simple boundary"
This is the preamble. It is to be ignored, though it
is a handy place for mail composers to include an
explanatory note to non-MIME compliant readers.
--simple boundary
This is implicitly typed plain ASCII text.
It does NOT end with a linebreak.
--simple boundary
Content-type: text/plain; charset=us-ascii
This is explicitly typed plain ASCII text.
It DOES end with a linebreak.
--simple boundary--
This is the epilogue. It is also to be ignored.
Addendum 2: I tried a simple upload (using content-type header message/rfc822) and it worked, except the message was unlabeled. How
would I specify what label I want applied to a message? I was originally trying to follow the documentation here
link
which tells me to create the json body that I gave above. This allows me to specify the label. But I cannot seem to use
this body in a simple upload. The content type is either invalid, or what Gmail imports is just literally the json body,
it does not parse out the raw data. If you could point me to a specific example showing the URI, message body, http headers
(not java code) that would be very useful to me.
OK never mind, I got it working by adding an empty message/rfc822 part to the body of the multipart upload. That satisfies Google, and the empty part is ignored in favor of the raw data.
You are doing a multipart upload,see here:
The body of the request is formatted as a multipart/related content
type [RFC2387] and contains exactly two parts. The parts are
identified by a boundary string, and the final boundary string is
followed by two hyphens.
This is why it works only for your messages with images or attachments, since your message
--test_abc123
is only one part.
In the past there was no check if this condition is fulfilled, so you might have gotten away with using multipart for 1-part-messages.
But now it's not possible anymore, so if have a single-part message, you should use Simple upload.
If you do not know in advance how many parts your message has, you can always try the multipart first, implementing a try...catch statement, and implement a simple upload request within catch in case of failure.

Azure Logic App: how to make a x-www-form-encoded?

I'm trying to make a request with Content-Type x-www-form-urlencoded that works perfectly in postman but does not work in Azure Logic App I receive a Bad Request response for missing parameters, like I'd not send enything.
I'm using the Http action.
The body value is param1=value1&param2=value2, but I tried other formats.
HTTP Method: POST
URI : https://xxx/oauth2/token
In Headers section, add the below content-type:
Content-Type: application/x-www-form-urlencoded
And in the Body, add:
grant_type=xxx&client_id=xxx&resource=xxx&client_secret=xxx
Try out the below solution . Its working for me .
concat(
'grant_type=',encodeUriComponent('authorization_code'),
'&client_id=',encodeUriComponent('xxx'),
'&client_secret=',encodeUriComponent('xxx'),
'&redirect_uri=',encodeUriComponent('xxx'),
'&scope=',encodeUriComponent('xxx'),
'&code=',encodeUriComponent(triggerOutputs()['relativePathParameters']['code'])).
Here code is dynamic parameter coming from the previous flow's query parameter.
NOTE : **Do not forget to specify in header as Content-Type ->>>> application/x-www-form-urlencoded**
Answering this one, as I needed to make a call like this myself, today.
As Assaf mentions above, the request indeed has to be urlEncoded and a lot of times you want to compose the actual message payload.
Also, make sure to add the Content-Type header in the HTTP action with value application/x-www-form-urlencoded
therefore, you can use the following code to combine variables that get urlEncoded:
concat('token=', **encodeUriComponent**(body('ApplicationToken')?['value']),'&user=', **encodeUriComponent**(body('UserToken')?['value']),'&title=Stock+Order+Status+Changed&message=to+do')
When using the concat function (in composing), the curly braces are not needed.
First of all the body needs to be:
{ param1=value1&param2=value2 }
(i.e. surround with {})
That said, value1 and value2 should be url encoded. If they are a simple string (e..g a_b) then this would be find as is but if it is for exmaple https://a.b it should be converted to https%3A%2F%2Fa.b
The easiest way I found to do this is to use https://www.urlencoder.org/ to convert it. convert each param separately and put the converted value instead of the original one.
Here is the screenshot from the solution that works for me, I hope it will be helpful. This is example with Microsoft Graph API but will work with any other scenario:

Example using poor-smime-sign

I am trying to send SMIME signed email and fail.
I use Python 3, so I chose the poor-smime-sign library.
Using Thunderbird to recieve, I either get an empty email with "undisclosed recipients" and no subject, which is signed or I get the whole thing in plain-text, printing a huge blob of base64 with the message-body - no sign of signing (pun unintended, noticed and left intact).
I have compared the source of a working email (created by Thunderbird from my sent folder) with my franken-mails, but I don't quite see the difference.
Here's the code:
from poor_smime_sign import smime_sign
def signEmail(self, message :str) -> str:
"""Sign the message-body.
The message is encoded in UTF-8, signed and then returned as Unicode.
Check this document on how to generate untrusted example-keys:
https://tools.ietf.org/doc/python-m2crypto/howto.smime.html
Check the settings ('invmail'->'keydir') where to put the keys.
The privateKey is called 'signer_key.pem' and publicKey 'signer.pem'.
"""
import os
privateKey = os.path.join(settings.SF.mail['keydir'], 'signer_key.pem')
publicKey = os.path.join(settings.SF.mail['keydir'], 'signer.pem')
try:
signed = smime_sign(publicKey, privateKey, message.encode('UTF-8'))
except Exception as e:
raise(Exception("Problem during signing: "+str(e)))
return signed.decode('UTF-8')
poor_smime_sign btw is pretty humble about their module, which I quite like. I looked at their code and all they do is call openssl, which is what I would have done, too, as the next step. If you're troubleshooting you can go into the mod and log the command that gets executed and fiddle with that in a shell until you understand why it fails. I e.g. had pub and priv cert the wrong way and got a really stupid error message.
This is what puts the message together in the end. I had copied it from some example somewhere.
body = self.signEmail(body)
emailAr = [
"From: %s" % emailFrom,
"To: %s" % emailTo,
"Subject: %s" % subject,
"", # <- that one
body,
]
message = "\r\n".join(emailAr)
#...
server.sendmail(emailFrom, [emailTo], message.encode('UTF-8'))
TL;DR:
Get the headers right: Signing already creates a header. Just add to that. No empty new lines.
Well, turns out I had no idea how email works. I was indeed wondering about why I use the TO-address twice (once constructing the message and once in sendmail()) but it took a while until I figured it out. I knew, that I needed some sort of header but I did not know where and why.
The solution was twofold:
The text that gets signed needs a header so the email client knows what to do with it. I took one from a working email I had lying around.
Looks like this.
cannedHeader = "\r\n".join([
"Content-Type: text/plain; charset=utf-8; format=flowed",
"Content-Language: de-DE",
"Content-Transfer-Encoding: quoted-printable",
"","" # emtpy new line concludes header
])
body = cannedHeader+bodyInput
body = self.signEmail(body)
The signed message-body already comes with a partial header attached to it. Printing out the result of signing, you see it starts with
MIME-Version: 1.0 Content-Type: multipart/signed;
protocol=3Dpplication/x-pkcs7-signature"; m= icalg=3Dha-256";
boundary=3D---DF20A931579CC3CE98F68AEF4D387131"
This is an S/MIME signed message
------DF20A931579CC3CE98F68AEF4D387131
And I ran that through the initial version of the code, generating two headers in the process. One with recipients and subject suffixed by an empty new line, and then added the signed message-body, which had another header, containing SMIME information, also suffixed by an empty new line. That could not work. So removing the empty line (in the question marked with "that line") fixed this.
As I have not found any example on stackexchange, I thought I'd write this down, so I can find it when I need it the next time.

How do I encode angle brackets in servicestack json response

I have a customer who wants to ensure that responses from our JSON web service do not contain HTML. So instead of returning a string containing angle brackets they want encoded angle brackets.
Two questions:
if I return content type application/json do I need to do this?
how can I do this globally in ServiceStack?
if I return content type application/json do I need to do this?
You should always return a JSON Mime Type like application/json for JSON Responses (ServiceStack automatically does this for you).
how can I do this globally in ServiceStack?
Support for Escaping HTML Chars was just added in this commit which will let you globally escape HTML chars into unicode notation with:
JsConfig.EscapeHtmlChars = true;
This change is available from v4.5.7+ that's now available on MyGet.
