Open Url in ruby
To open a URL in Ruby, you can use the open-uri
library. Here's a step-by-step explanation of how to do it:
- First, you need to require the
open-uri
library. This library provides methods for opening URLs.
require 'open-uri'
- Next, you can use the
open
method fromopen-uri
to open a URL. It takes the URL as a parameter and returns anIO
object that you can read from.
url = 'https://www.example.com'
open(url)
- If you want to read the contents of the URL, you can use the
read
method on theIO
object returned byopen
.
url = 'https://www.example.com'
io_object = open(url)
content = io_object.read
- You can also specify additional options when opening a URL. For example, you can set the
User-Agent
header to specify the user agent of the request.
require 'open-uri'
url = 'https://www.example.com'
options = {
'User-Agent' => 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
}
open(url, options)
- Finally, don't forget to close the
IO
object when you're done with it to free up system resources.
require 'open-uri'
url = 'https://www.example.com'
io_object = open(url)
# Do something with the content...
io_object.close
That's it! These steps should help you open a URL in Ruby using the open-uri
library.
