HttpClientRequest encoding setting

Hello,

 

We are doing a JS where a HttpClientRequest is used for pushing a request to another 3rd party REST API. In this request we are setting the header Content-type to application/json with charset=utf-8. However, the 3rd party that is receiving the request is not receiving it with UTF-8 encoding but in another encoding (windows-1252). Question: is there another setting other than the HttpClientRequest header that might change the encoding of a request done from ACC to another API?

The way you can use HttpClientRequest is in a JS activity in a workflow and it looks like:

var request = new HttpClientRequest(url);
request.connect();
request.method = "POST";
request.body = data;
request.header["Content-Type"] = "application/json;charset=UTF-8";
request.execute();

In this request the connect() and execute() methods have some optional parameters for when the endpoint has a proxy or if you want to have a call async. Documentation here: https://docs.adobe.com/content/help/en/campaign-classic/technicalresources/api/c-HttpClientRequest.h... 

However, it seems like the way the connect and execute methods are setup up is interfering with the Content-Type header meaning that in some configuration the Content-Type set up like in the above code is ignored.
This seems to be related to the proxy setting on the ACC environment we are working in. We managed to find a working code by not setting up any optional parameters but only using connect() and execute() as they are.

Hi,

 

I've never been able to get HTTPClientRequest to set content-type header.

What I've done to solve is make a drop-in replacement for HTTPClientRequest class, wrapping execCommand('curl').

HTTPClientRequest is libcurl anyway.

 

Thanks,

Hi @samy_doe, @jonathon_wodnicki ,

 

I need your help here.

We are also writing the POST method for Rest API call via javascript in the Campaign Classic version to get the access token from the server.

We are having 4 parameters which are "Grant_Type", "Client_id", "Client_secret", and "Scope" needs to be send in the body of the request and using the Content_Type as "application/x-www-form-urlencoded".

Can you please help me with how to send the 4 parameters in the body? I am trying all the ways but getting the errors like "invalid_client" and "unsupported_grant_type".

Can you please help?

 

Thanks,

Raviteja Gundu.

Hi Team,

 

The issue is resolved now. We need to send the grant type, client_id, client_secret in body as a query string. We were able to get the access token now.

http.body="grant_type=<value>&client_id=<value>&client_secret=<value>&scope=<value>";

 

Hope it will help someone.

 

Thanks,

Raviteja Gundu.
