QUESTION
Reproduction of the error here. Please remove the comments before the exception throwing to see the problem. Path is: http://localhost:8080/api/download
Original Question: I am allowing users to download reports using JasperReports in an Angular7 App, but the problem is only connected to Spring Boot. The report generation works, but I can't get the file download to behave as I expected.
Currently:
The download link is used with an href
, link with target="_blank"
. The user clicks on it and the browser opens a new tab (in the background) and pops-up the File Save As
window. If everything is okay, the file is saved without a problem. However if there is an exception during the PDF generation somewhere, the browser still pops-up the File Save As
window and allows the user to save the file, it will complete, but the file will be 0 bytes
.
Should be: When there is an exception, the browser should open a new tab with an error message of some sort, but If If there were no errors, it should display the File Save As window.

QUESTION
I've been trying to scrape the table from here but it seems to me that BeautifulSoup doesn't find any table.

Answered 2017-Feb-18 at 02:59While this won't find the table that's not in r.text
, you are asking BeautifulSoup
to use the xml
parser instead of html.parser
so I would recommend changing that line to:
soup=BeautifulSoup(data,'html.parser')
One of the issues you will run into with web scraping is what are called "client-rendered" websites versus server-rendered. Basically, this means that the page you would get from a basic html request through the requests
module or through curl
for example is not the same content that would be rendered in a web browser. Some of the common frameworks for this are React and Angular. If you examine the source of the page you are wanting to scrape, they have data-react-id
s on several of their html elements. A common tell for Angular pages are similar element attributes with the prefix ng
, e.g. ng-if
or ng-bind
. You can see the page's source in Chrome or Firefox through their respective dev tools, which can be launched with the keyboard shortcut Ctrl+Shift+I
in either browser. It's worth noting that not all React & Angular pages are only client-rendered.
In order to get this sort of content, you would need to use a headless browser tool like Selenium. There are many resources on web scraping with Selenium and Python.
