REST file upload with Jersey client

[driekhof]

I'm able to upload a file with curl from command prompt like this:

$ curl –form "filedata=@test.txt" –form siteid=mysite –form containerid=documentLibrary –form uploaddirectory=java http://localhost:8080/alfresco/service/api/upload?alf_ticket=MYTICKET

I'm also able to use my ticket to successfully do GETs in Jersey Java client.

But I can't get the file upload to work in my jersey client.  The response is showing a 500 status.  Here's my code:

private static void upload() {
   System.out.println("ticket=" + ticket);

   // i've tried putting ticket here and as request param
   String payload = "{" +
//            "\"alf_ticket\":"+ ticket + "," +
            "\"filedata\":\"@test2.txt\"," +
            "\"siteid\":\"mysite\"," +
            "\"containerid\":\"documentLibrary\"," +
            "\"uploaddirectory\":\"java\"" +
            "}";
System.out.println("payload=" + payload);
      
      
//      WebTarget target = client.target(getBaseURI(uriUpload));
      WebTarget target = client.target(getBaseURI(uriUpload)).queryParam("alf_ticket", ticket);

/// I've tried a few things here, nothing works      
//      Response response = target.request().accept(MediaType.TEXT_PLAIN).post(
//            Entity.entity(payload, MediaType.APPLICATION_JSON), Response.class);
      Response response = target.request().accept(MediaType.APPLICATION_JSON).post(
//      Response response = target.request().accept(MediaType.MULTIPART_FORM_DATA).post(
            Entity.entity(payload, MediaType.APPLICATION_JSON), Response.class);

System.out.println("response=" + response);
      

      String plainAnswer = target.request().accept(MediaType.TEXT_PLAIN).get(String.class);

      System.out.println("response=" + response.toString());
      System.out.println("plain=" + plainAnswer);
   }
}

and here's my log:

Any suggestions on what's wrong or how to debug the problem?

Finally found a solution, used multipart form instead of raw json:

   public static void upload2()
   {
      System.out.println("ticket=" + ticket);
      
      
       Client clientUpload = ClientBuilder.newBuilder().register(MultiPartFeature.class).build();
       FileDataBodyPart filePart = new FileDataBodyPart("filedata", new File("test2.txt"));
       FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
       
       FormDataMultiPart multipart = 
             (FormDataMultiPart)formDataMultiPart.field("siteid", "mysite")
                                                      .field("containerid", "documentLibrary")
                                                      .field("uploaddirectory", "java")
                                                      .bodyPart(filePart);

       WebTarget target = clientUpload.target(getBaseURI(uriUpload)).queryParam("alf_ticket", ticket);
       Response response = target.request().post(Entity.entity(multipart, multipart.getMediaType()));
        
       System.out.println("response=" + response);
       try {
      formDataMultiPart.close();
           multipart.close();
       } catch (IOException e) {
      e.printStackTrace();
       }
   }

I'm trying to set the title and description fields for the uploaded file.  I thought it would be as easy as this, but it's not working:

FormDataMultiPart multipart = (FormDataMultiPart) formDataMultiPart
            .field("siteid", site).field("containerid", "documentLibrary")
            .field("title", "THIS DOESNT WORK").field("description", "NEITHER DOES THIS")
            .field("uploaddirectory", uploadFolder).bodyPart(filePart);

Any ideas?
