SAP PO-HTTP_AAE RECEIVER - FORM DATA WITH XML ATTACHMENT

[former_member600697]

Hi All,

My scenario is Proxy to HTTP_AAE FormData, which is the service I need to send data to.

While sending the API formdata, I am experiencing the 400-Bad Request issue.

We are able to post the data via Postman, and the following are the API logs for Postman

In the receiver HTTP communication channel, the following configuration is used.

The next java mapping sends this information. The import mode of the .xml file is "NORMAL" which sends it through the form data service.

package com.test.sap.pi.file;

public class CreateForm implements StreamTransformation {

     private String boundary;
     private String boundary2;

     private static final String LINE_FEED = "\r\n";

     private HttpURLConnection httpConn;

     private String charset;

     private String body;

     private OutputStream outputStream;

     private PrintWriter writer;

     public void execute(InputStream arg0, OutputStream arg1)

  throws StreamTransformationException {

  // TODO Auto-generated method stub

         // creates a unique boundary based on time stamp

        // boundary = �===� + System.currentTimeMillis() + �===�;

         boundary = "--ejjeeffe1";
         boundary2 = "--ejjeeffe1--";

         //body = "Content-Type: multipart/form-data; boundary=";

        // body =  boundary + LINE_FEED ;

//        body.concat(boundary);

         addFormField("import_mode","NORMAL" );

        // addFormField("Filename","PriceFeed.xml" );

  

         body =body + boundary;

  

         body = body + LINE_FEED + "Content-Disposition: form-data; name=\"" + "file" +

         "\"" + "; " + "filename=\"" + "PriceFeed.xml" + "\"" +

          LINE_FEED + "Content-Type: text/xml"  + LINE_FEED + LINE_FEED;

 

         byte[] buffer = new byte[4096];

         byte[] message = body.getBytes();

     //    int bytesRead = -1;

         try {

  int len = -1;

  while ((len = arg0.read(buffer)) != -1) {

  arg1.write(buffer, 0, len);

  }

  } catch (IOException e) {

  e.printStackTrace();

  }

  

        String endchar = LINE_FEED + boundary2;

  try {

  arg1.write(endchar.getBytes());

  } catch (Exception e) {

  e.printStackTrace();

  }

  }

  public void setParameter1(Map arg0) {

  // TODO Auto-generated method stub

  }

    /**

     * Addsa form field to the request

    public void addFormField(String name, String value) {

    	  body =  boundary + LINE_FEED + "Content-Disposition: form-data; name=\"" + name + "\""

    			    + value + LINE_FEED;

    }

	public void setParameter(Map param) {
		// TODO Auto-generated method stub

}<br>

I receive the following response after submitting

The SWC was removed from the ICO.

Could you please suggest a solution to this scenario?

Your comments would be greatly appreciated,

I think that in the end there should be two new lines:

String endchar = LINE_FEED + LINE_FEED + boundary2;

I have the same case. But my interface not working. Can you help me?, please.

My java mapping code

Any suggestions?.
