Download file from SAPUI5 application.

[Former Member]

Hi all,

my purpose is to dowload a file from a SAPUI5 application.

I found some discussion about this topic, but always using the sap gateway, but in my case this is not possible because I do not have the gateway.

In my scenario the user click on a file name in a list and through an ajax call I extract the file content in xstring format.

this is the code in the controller of my view

	var oParameters = {
		title: oObject.phio_fname,   //filename
		type:  oObject.phio_ext,     //file type
		id: selectedDetail.id           //purchase order number

    };

    //Ajax to back-end

    $.ajax({

	url : "/zui5/index.html?application=POA&area=DOWNLOAD_ATTACH",
	contentType : "application/json",
	dataType : 'json',
	data : oParameters
	});    //Ajax call completed

in my http handler

  CALL FUNCTION 'SCMS_BINARY_TO_XSTRING'

    EXPORTING

      input_length       = lv_bin_size

    IMPORTING

      BUFFER             = lv_xstring

    tables

      binary_tab         = lt_phio_content

*   EXCEPTIONS

*     FAILED             = 1

*     OTHERS             = 2        .

  ls_file-file_name     = lv_title.

  ls_file-file_type     = lv_type.

  ls_file-file_content  = lv_xstring.

	server->response->set_data( data = ls_file-file_content ).
	server->response->set_content_type( content_type = ls_file-file_type ).

Everything work correctly until the server response, but I am not getting any result in my page.

Is it possible to achieve this result without the gateway?

If not what I am missing?

Thanks in advance.

you dont need ajax..

Download File Using Javascript/jQuery - Stack Overflow

var $idown;  // Keep it outside of the function, so it's initialized once.
downloadURL : function(url) {
  if ($idown) {
  $idown.attr('src',url);
  } else {
  $idown = $('<iframe>', { id:'idown', src:url }).hide().appendTo('body');
  }
},
//... How to use it:
downloadURL('/zui5/index.html?application=POA&area=DOWNLOAD_ATTACH' + jQuery.param( oParameters ) );

Hi everybody,

you can use sap.m.URLHelper in SAPUI5, which has some positive effects. Here is a blog-article, that discusses the disadvantage of other methods like using an iframe:
