em-http-requestvshrequests
em-http-request is a Ruby gem for making asynchronous HTTP requests using EventMachine. It allows you to perform multiple requests simultaneously and handle the responses as they come in, rather than waiting for each request to complete before making the next one.
In short it supports: - Asynchronous HTTP API for single & parallel request execution - Keep-Alive and HTTP pipelining support - Auto-follow 3xx redirects with max depth - Automatic gzip & deflate decoding - Streaming response processing - Streaming file uploads - HTTP proxy and SOCKS5 support - Basic Auth & OAuth - Connection-level & global middleware support - HTTP parser via http_parser.rb - Works wherever EventMachine runs: Rubinius, JRuby, MRI
hrequests is a feature rich modern replacement for a famous requests library for Python. It provides a feature rich HTTP client capable of resisting popular scraper identification techniques: - Seamless transition between headless browser and http client based requests - Integrated HTML parser - Mimicking of real browser TLS fingerprints - Javascript rendering - HTTP2 support - Realistic browser headers
Highlights
Example Use
EventMachine.run {
http = EventMachine::HttpRequest.new('http://google.com/').get :query => {'keyname' => 'value'}
# add callback for errors:
http.errback { p 'Uh oh'; EM.stop }
# add callback for successful requests
http.callback {
p http.response_header.status
p http.response_header
p http.response
EventMachine.stop
}
}
import hrequests
# perform HTTP client requests
resp = hrequests.get('https://httpbin.org/html')
print(resp.status_code)
# 200
# use headless browsers and sessions:
session = hrequests.Session('chrome', version=122, os="mac")
# supports asyncio and easy concurrency
requests = [
hrequests.async_get('https://www.google.com/', browser='firefox'),
hrequests.async_get('https://www.duckduckgo.com/'),
hrequests.async_get('https://www.yahoo.com/'),
hrequests.async_get('https://www.httpbin.org/'),
]
responses = hrequests.map(requests, size=3) # max 3 conccurency
