Re: POST multipart/form-data with Invokehttp

[Etienne Jouvin]

Hello.

I did it with a processor ExecuteGroovyScript.

The script body is something like :

import org.apache.http.entity.mime.MultipartEntityBuilder
import org.apache.http.entity.ContentType

flowFileList = session.get(100)
if(!flowFileList.isEmpty()) {
  flowFileList.each { flowFile ->
    def multipart
    String text = flowFile.read().getText("UTF-8")

    flowFile.write{streamIn, streamOut->
      multipart = MultipartEntityBuilder.create()
        //specify multipart entries here
        .addTextBody("object", text, ContentType.APPLICATION_JSON)
        .addBinaryBody("content", new
File(flowFile.'document.content.path'),
ContentType.create(flowFile.'document.mime.type'), flowFile.'document.name')
        .build()
      multipart.writeTo(streamOut)
    }
    //set the `documentum.action.rest.content.type` attribute to be used as
`Content-Type` in InvokeHTTP
    flowFile.'document.content.type' = multipart.getContentType().getValue()
    session.transfer(flowFile, REL_SUCCESS)
  }
}


Attributes are :

   - document.content.path : content path
   - document.mime.type : content mime type
   - document.name : binaire content name


Output update attribute
document.content.type : multipart content type.

You need some extra librairies :

   - httpcore-4.4.12.jar
   - httpmime-4.5.10.jar


This will build a multipart as the flowfile content and you can use it for
the call after.
