Post a text request in Casablanca (C++ REST SDK) - visual-c++

I am writing a client side code in Visual C++ 2012 using C++ Rest SDK (codename "Casablanca").
I have a client created and wish to POST a text string to the server. However, when I send the following code, it is compiling but not sending sending the request.
When I remove everything after "methods::POST" and send a blank post request, then it is sent and received by the server.
Can you please guide me where the problem is. The documentation related to this function is available on Casablanca Documentation.
pplx::task<http_response>resp = client.request(methods::POST,L"",L"This is the random text that I wish to send", L"text/plain");

I think the usage you give here looks correct.
Is your Casablanca the latest version ? Please check that out from here : http://casablanca.codeplex.com/
If you are sure your measurement is accurate, you may want to create a minimal repro and file a bug here : http://casablanca.codeplex.com/workitem/list/basic

I was having a similar problem, all my POSTs was arriving in blank on server , after a few hours work above it, i found a possible solution.
I changed the default content type to application/x-www-form-urlencoded and I started to pass the values like this Example data=text1&data2=text2
client.request(methods::POST,L"",L"data=text1&data2=text2", L"application/x-www-form-urlencoded");

The body parameter must be a json::value.

I cannot comment yet so I have to put my thoughts in an answer. I solved this problem like this: There is an overload of the request method that takes as a parameter the content type so that you do not have to change the code.
m_client->request(methods::POST, L"/statuses/update.json?" + url_encode(data),L"",L"application/x-www-form-urlencoded");
Obviously you would have to implement the url_encode method but that is not difficult. There is a pretty good implementation in "Cassablanca". A search on this site will alos turn up some good examples.

discord webhook can not send empty message

I have written this small PoC for discord webhooks and i am getting error that Can not send empty string. I tried to google but couldn't find a documentation or an answer
here is my code
import requests
discord_webhook_url = 'https://discordapp.com/api/webhooks/xxxxxxxxxxxxxxxxxx/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
data = {'status': 'success'}
headers = {'Content-Type': 'application/json'}
res = requests.post(discord_webhook_url, data=data, headers=headers)
print(res.content)
I'm late, but I came across this issue recently, and seeing as it has not been answered yet, I thought I document my solution to the problem.
For the most part, it is largely due to the structure of the payload being wrong.
https://birdie0.github.io/discord-webhooks-guide/discord_webhook.html provides an example of a working structure. https://discordapp.com/developers/docs/resources/channel#create-message is the official documentation.
I was also able to get a minimum test case working using: {"content": "Test"}.
If it still fails after that with the same error, the likely causes are:
If using curl, check to make sure there are no accidental escape / backslashes \
If using embeds with fields, ensure there are no empty values
When in doubt, ensure all values are populated, and not "". Through trial-and-error / the process of cancellation, you can figure out exactly what key-value pair is causing an issue, so I suggest playing with the webhook via curl before turning it into a full program.

Gmail IMAP via php ouath2 Zend_Mail_Protocol_Imap - getting the X-GM-THRID

I'm accessing GMail via IMAP using OAuth2 authentication and Zend_Mail_Protocol_Imap.
It all works great.
What I need to do is present emails in thread form just like the GMail interface. Google make this really easy because they have an X-GM-THRID header that links a conversation with a 64-bit unsigned integer.
My problem is: when presented with a single email, how do I find out what X-GM-THRID it belongs to?
First off Google says that there is a server extension X-GM-EXT-1 which is active. You can check it is there using the CAPABILITY command (and I have).
All the information suggests that if this is active then the X-GM-THRID will simply be returned as a header, but it isn't.
Perhaps I need to ask Google to return it via the fetch command. Google does describe a simple fetch process here:
https://developers.google.com/google-apps/gmail/imap_extensions
My code is sending TAG5 FETCH 3673 (FLAGS RFC822.HEADER X-GM-THRID) but the headers do not include an entry for X-GM-THRID.
I've even simplified it to TAG6 FETCH 3673 (X-GM-THRID) to be exactly as described in the google example. In this case no headers are returned.
I'm not massively familiar with IMAP commands and I'm not sure if Zend_Mail_Protocol_Imap is abstracting some handling which means this header is being removed.
But I do know that this is driving me mad.
Am I missing something? Is it not a header?
Okay, so it looks like it is not a header. It is an attribute in the IMAP command and response.
The standard fetch command sent by Zend_Mail_Protocol_Imap is "TAG5 FETCH 3673 (FLAGS RFC822.HEADER)"
The code that handles the response only expects to be dealing with 'FLAGS' and 'RFC822.HEADER'. It passes this information to a Zend_Mail_Message object which extends Zend_Mail_Part.
Zend_Mail_Part parses information about flag. It also parses the header.
The additional 'X-GM-THRID' attribute that I added does actually get a response. but since it is not passed back to Zend_Mail_Message there is no way for me to use it. It gets lost in the ether (at around line 171 of Zend_Mail_Storage_Imap in my Zend Library to be exact).
So I've hacked the core... Zend_Mail_Storage_Imap::getMessage now expects $data['X-GM-THRID'] and passes it to the constructor Zend_Mail_Part. And I now have a method Zend_Mail_Part::getXGmThrid which solves all my problems. I'll obviously refactor them into my own classes extending Zend_Mail_Storage_Imap and Zend_Mail_Part in the not too distant... but for now I know this works.

how to get request body in varnish

I am currently working on a project based on varnish..
we write vcl and vmod. But the project needs to check the request body.
How can I get the post request body in VCL or vmod with a C function?
You can do almost everything you want with VCL/VMOD.
You should try to call a VMOD subroutine in vcl_recv, and then in C code, write something like below :
Use VRT_GetHdr(rec->s, HDR_REQ, "\017Content-Length:"); to read the body length
Use HTC_Read(rec->s->htc, body, bodylen);
And enjoy !
You should take a look at existing vmods https://www.varnish-cache.org/vmods, and be free to look into the varnish API sources.
I'm not sure you can.
Varnish generally only deals with Req/Resp headers.
The bodies are passed along without (much) modification.
I you do find a solution please let me know as I'm interested in this as well.

Quicklfix related question(FIX::Application)

I am trying to use FIX::Application along with SessionSettings.
The Fix server I am trying to connect to does not see any incoming connection. From my side I see a Logon Message being formulated in toAdmin() callback(which I print out and add certain fields to.
The Question is
1. Do I need to call some form of sendTarget in toAdmin?(I tried that but get a Session not found error)
2. Is there anyway I can increase logging(start logging whats going on under the hood).
Thanks
Firstly the sendTOTarget need not be called in the toAdmin.
As far as logging goes, what i hear is passing th in FIX::LogFactory should be enough.
