Opening PDF files in web browser

[José Eloy]

Hello!

I've developed an application that allows users to upload document files (doc, pdf, xls) and then download them. The problem is when the user wants download the files the web browser always opens a window to ask where to download them (or the file is downloaded in the download folder). In the case of doc and xls files is fine, but would it be possible that the pdf files will open directly in the web browser?. To upload/download the files I use the standard way of web2py. This problem occurs with Firefox, Safari, Chrome, IE 10. The version of web2py I use with the application is the 1.99.7.

I hope you can understand me, my english is not very good.

Thanks ins advanced.

Regards

You need to change your download for PDFs controller, this would work if you don't use uploadseparate (which I usually do) :

def download_pdf():

      filename=request.args[0]

      path=os.path.join(request.folder,'uploads', filename)

      response.headers['ContentType'] ="application/pdf"

      response.headers['Content-Disposition']="inline; " + filename

      return response.stream(open(filename), chunk_size=65536)

If you want to avoid the Acrobat plugin entirely and show pdf inline:
https://github.com/mozilla/pdf.js

It's already included in Firefox, but the other browsers can use it too

Sorry for my delay in answer. I've taken back the project.

The solution of Leonel works well if I want to show an pdf from
another website, but when I try to download a file loaded in my own
web site (Web2py's upload/download method) I get the message that the
file is not found.

I show you the table definition:

db.define_table('enlacesweb_documentos',
Field('categoria', db.categorias_documentos),
Field('nombre'),
Field('documento', 'upload',
uploadfolder=os.path.join(request.folder,'uploads/docs_y_normatividad')),
Field('fecha', 'date'),
Field('descripcion_documento', 'text'),
Field('muestra_en_portada','boolean'),
Field('imagen_portada', 'upload',
uploadfolder=os.path.join(request.folder,'uploads/docs_y_normatividad')),
Field('texto_imagen_portada', label="Texto de la
imagen en portada"),
format='%(categoria)s')


As you see I'm using an subfolder inside uploads folder.

The download function, serving swf, pdf and another type of files:

def download():
"""
allows downloading of uploaded files
http://..../[app]/default/download/[filename]
"""

import os

if (request.args(0) or '').endswith('swf'):

response.headers['Content-Disposition'] = ''
filename = os.path.join(request.folder, 'uploads', request.args(0))

return response.stream(open(filename,'rb'))

elif (request.args(0) or '').endswith('pdf'):

filename=os.path.join(request.folder, 'uploads', request.args(0))

response.headers['ContentType'] ="application/pdf"
response.headers['Content-Disposition']="inline; filename.pdf"

+ filename

return response.stream(open(filename), chunk_size=65536)

else:
return response.download(request,db)


The elif section works well with external pdf to show, but for those
uploaded with Web2py's upload method I get the error the pdf is not
found, if I omit the elif and use the else I can to download the pdf
file, but I want the web browser open it.

I hope you can understand me.

How to fix this?

Thanks in advanced.

Hello.

I've discovered if I use

    return response.download(request, db, attachment=False)

in the else statement of the download function of my code, I can do the web browser can open the pdf file, but I miss the original filename. How I can to recover it?

Regards.

Any Idea?

But, if I have a PDF stored in a blob field, how could I use PDF.js do display it?
