Display PDF files REST API

I am using RESTful API with python and flask to list all PDF files of a folder. The PDF filenames are displayed with their complete path. For example, http://127.0.0.1:5000/getPDFs shows the following

test1.pdf /home/PATH/test1.pdf
test2.pdf /home/PATH/test2.pdf

Now, I would like to add a link to all the paths and when the path is clicked, the PDF files should be displayed on the browser. If I click the /home/PATH/test1.pdf it should go to http://127.0.0.1:5000/getPDFs/test1.pdf and display the pdf file.

Any help would be appreciated.

Solution

  • You need to implement a route that points to the pdf you are looking for, in your case:

    @app.route('/getPDFs/<path:filename>')
def download_file(filename):
    return send_from_directory(app.config['PATH'],
                               filename, as_attachment=True)

    Your file should be visible by your flask app. You can find the documentation for send_from_directory here:
