HTTPX is an HTTP client library for the Ruby programming language.
Among its features, it supports:
- HTTP/2 and HTTP/1.x protocol versions
- Concurrent requests by default
- Simple and chainable API
- Proxy Support (HTTP(S), Socks4/4a/5)
- Simple Timeout System
- Lightweight by default (require what you need)
And also:
- Compression (gzip, deflate, brotli)
- Streaming Requests
- Authentication (Basic Auth, Digest Auth)
- Expect 100-continue
- Multipart Requests
- Cookies
- HTTP/2 Server Push
- H2C Upgrade
- Automatic follow redirects
- International Domain Names
Here are some simple examples:
HTTPX.get("https://nghttp2.org").to_s #=> "<!DOCT...."
And that's the simplest one there is.
If you want to do some more things with the response, you can get an HTTPX::Response
:
response = HTTPX.get("https://nghttp2.org")
puts response.status #=> 200
body = response.body
puts body #=> #<HTTPX::Response ...
You can also send as many requests as you want simultaneously:
page1, page2, page3 = HTTPX.get("https://news.ycombinator.com/news", "https://news.ycombinator.com/news?p=2", "https://news.ycombinator.com/news?p=3")
Add this line to your Gemfile:
gem "httpx"
or install it in your system:
> gem install httpx
and then just require it in your program:
require "httpx"
In Ruby, HTTP client implementations are a known cheap commodity. Why this one?
This library supports HTTP/2 seamlessly (which means, if the request is secure, and the server support ALPN negotiation AND HTTP/2, the request will be made through HTTP/2). If you pass multiple URIs, and they can utilize the same connection, they will run concurrently in it.
However if the server supports HTTP/1.1, it will try to use HTTP pipelining, falling back to 1 request at a time if the server doesn't support it (if the server support Keep-Alive connections, it will reuse the same connection).
httpx
builds all functions around the HTTPX
module, so that all calls can compose of each other. Here are a few examples:
response = HTTPX.get("https://www.google.com")
response = HTTPX.post("https://www.nghttp2.org/httpbin/post", params: {name: "John", age: "22"})
response = HTTPX.plugin(:basic_authentication)
.basic_authentication("user", "pass")
.get("https://www.google.com")
It ships with a plugin system similar to the ones used by sequel, roda or shrine.
It means that it loads the bare minimum to perform requests, and the user has to explicitly load the plugins, in order to get the features he/she needs.
It also means that it ships with the minimum amount of dependencies.
HTTPX
ships with custom DNS resolver implementations, including a DNS-over-HTTPS resolver.
The test suite runs against httpbin proxied over nghttp2, so there are no mocking/stubbing false positives. The test suite uses minitest, but its matchers usage is (almost) limited to #assert
(assert
is all you need).
All Rubies greater or equal to 2.1, and always latest JRuby and Truffleruby.
Note: This gem is tested against all latest patch versions, i.e. if you're using 2.2.0 and you experience some issue, please test it against 2.2.10 (latest patch version of 2.2) before creating an issue.
HTTPS
TLS backend is ruby's own openssl
gem.
If your requirement is to run requests over HTTP/2 and TLS, make sure you run a version of the gem which compiles OpenSSL 1.0.2 (Ruby 2.3 and higher are guaranteed to).
In order to use HTTP/2 under JRuby, check this link to know what to do.
- Doesn't work with ruby 2.4.0 for Windows (see #36).
- Using
total_timeout
along with the:persistent
plugin does not work as you might expect.
- Discuss your contribution in an issue
- Fork it
- Make your changes, add some tests
- Ensure all tests pass (
bundle exec rake test
) - Open a Merge Request (that's Pull Request in Github-ish)
- Wait for feedback
