Question

I have a module in a lib/assets file as follows:

require 'net/http'
require 'cgi'
require 'json'

 module FetchRec
  rate.sample(5).each do |result|
    begin
      url = URI.parse("http://www.url.com/dprc=Y&item_id=#{result["item"]}")
     rescue
        next 
      end
     r = JSON.parse(Net::HTTP.get_response(url).body)
  end

When I start my server I get an exception: Syntax Error — “Invalid next”

How can I handle exceptions in this module, so that if a url is not valid, the json parse script will skip to the next url, and parse that?

Answer 1

try removing the begin rescue block and replace with

url = URI.parse("http://www.url.com/dprc=Y&item_id=#{result["item"]}") rescue nil
next if url.nil?
