Equivalent of cURL for Ruby?
RubyCurlRuby Problem Overview
Is there a cURL library for Ruby?
Ruby Solutions
Solution 1 - Ruby
Curb and Curl::Multi provide cURL bindings for Ruby.
Solution 2 - Ruby
If you like it less low-level, there is also Typhoeus, which is built on top of Curl::Multi.
Solution 3 - Ruby
Use OpenURI and
open("http://...", :http_basic_authentication=>[user, password])
accessing sites/pages/resources that require HTTP authentication.
Solution 4 - Ruby
Curb-fu is a wrapper around Curb which in turn uses libcurl. What does Curb-fu offer over Curb? Just a lot of syntactic sugar - but that can be often what you need.
Solution 5 - Ruby
HTTP clients is a good page to help you make decisions about the various clients.
Solution 6 - Ruby
You might also have a look at Rest-Client
Solution 7 - Ruby
the eat gem is a "replacement" for OpenURI, so you need to install the gem eat in the first place
$ gem install eat
Now you can use it
require 'eat'
eat('http://yahoo.com') #=> String
eat('/home/seamus/foo.txt') #=> String
eat('file:///home/seamus/foo.txt') #=> String
It uses HTTPClient under the hood. It also has some options:
eat('http://yahoo.com', :timeout => 10) # timeout after 10 seconds
eat('http://yahoo.com', :limit => 1024) # only read the first 1024 chars
eat('https://yahoo.com', :openssl_verify_mode => 'none') # don't bother verifying SSL certificate
Solution 8 - Ruby
If you know how to write your request as a curl command, there is an online tool that can turn it into ruby (2.0+) code: curl-to-ruby
Currently, it knows the following options: -d/--data, -H/--header, -I/--head, -u/--user, --url, and -X/--request. It is open to contributions.
Solution 9 - Ruby
There's also Mechanize, which is a very high-level web scraping client that uses Nokogiri for HTML parsing.
Solution 10 - Ruby
Here's a little program I wrote to get some files with.
base = "http://media.pragprog.com/titles/ruby3/code/samples/tutthreads_"
for i in 1..50
url = "#{ base }#{ i }.rb"
file = "tutthreads_#{i}.rb"
File.open(file, 'w') do |f|
system "curl -o #{f.path} #{url}"
end
end
I know it could be a little more eloquent but it serves it purpose. Check it out. I just cobbled it together today because I got tired of going to each URL to get the code for the book that was not included in the source download.
Solution 11 - Ruby
Adding a more recent answer, HTTPClient is another Ruby library that uses libcurl, supports parallel threads and lots of the curl goodies. I use HTTPClient and Typhoeus for any non-trivial apps.
Solution 12 - Ruby
To state the maybe-too-obvious, tick marks execute shell code in Ruby as well. Provided your Ruby code is running in a shell that has curl:
puts `curl http://www.google.com?q=hello`
or
result = `
curl -X POST https://www.myurl.com/users \
-d "name=pat" \
-d "age=21"
`
puts result
