How can I catch Zlib::BufError in my Ruby on Rails code?

问题

I have built an app with Rails. I have a large list of addresses which I am standardizing via the Bing/Google API using Geocoder. This is my current call to get the adddress info:

Geocoder.search(address)

This works perfectly fine and I can parse the response JSON. However when I leave the script running it sometimes falls over with the following error:

Zlib::BufError: buffer error

Instead of the script falling over I would like to catch this error and continue with the script. How could I do this with Ruby? I am not sure which exception to catch, if any.

回答1:

To ensure Zlib is available, you need to require 'zlib' in the file where you want to catch the error. It doesn't look like Geocoder has declared that as a dependency itself anywhere, so it may not be loaded when your rescue line is being evaluated.

require 'zlib'

begin
  Geocoder.search('110 William St, 28th Floor New York, NY 10038')
rescue Zlib::BufError => boom
  puts 'Stack Overflow appears to have moved.'
end
