treq is a Python library for making HTTP requests that provides a simple, convenient API for interacting with web services. It is inspired byt the popular requests library, but powered by Twisted asynchronous engine which allows promise based concurrency.

treq provides a simple, high-level API for making HTTP requests, including methods for GET, POST, PUT, DELETE, etc. It also allows for easy handling of JSON data, automatic decompression of gzipped responses, and connection pooling.

treq is a lightweight library and it's easy to use, it's a good choice for small to medium-sized projects where ease of use is more important than performance.

In web scraping treq isn't commonly used as it doesn't support HTTP2 but it's the only Twisted based HTTP client. treq is also based on callback/errback promises (like Scrapy) which can be easier to understand and maintain compared to asyncio's corountines.

http is an HTTP library for Ruby, it's a fork of the Ruby standard library Net::HTTP. It is designed to provide a more modern and consistent API for making HTTP requests and handling responses.

One of the main goals of http is to simplify the process of making HTTP requests and handling responses. It provides a consistent API for making requests and handling responses across different versions of Ruby and different HTTP libraries, making it easier to write cross-compatible code.

http supports all the standard HTTP methods such as GET, POST, PUT, DELETE, and PATCH, and allows you to set headers, query parameters, and request bodies.

Example Use


from twisted.internet import reactor
from twisted.internet.task import react
from twisted.internet.defer import ensureDeferred
import treq

# treq can be used with twisted's reactor with callbacks
response_deferred = treq.get(
    "http://httpbin.org/get"
)
# or POST
response_deferred = treq.post(
    "http://httpbin.org/post",
    json={"key": "value"},  # JSON
    data={"key": "value"},  # Form Data
)

# add callback or errback
def handle_response(response):
    print(response.code)
    response.text().addCallback(lambda body: print(body))
def handle_error(failure):
    print(failure)
# this callback will be called when request completes:
response_deferred.addCallback(handle_response)
# this errback will be called if request fails
response_deferred.addErrback(handle_error)
# this will be called if request completes or fails:
response_deferred.addBoth(lambda _: reactor.stop())  # close twisted once finished

if __name__ == '__main__':
    reactor.run()

#Note that treq can also be used with async/await:
async def main():
    # content reads response data and get sends a get request:
    print(await treq.content(await treq.get("https://example.com/")))

if __name__ == '__main__':
    react(lambda reactor: ensureDeferred(main()))
</div>
<div class="lib-example" markdown>

```ruby
require 'http'

# GET request
response = HTTP.get("http://httpbin.org/get")
puts response.body
puts response.status
puts response.headers

# POST request
response = HTTP.post("http://httpbin.org/post", json: { title: 'foo', body: 'bar', userId: 1 })
puts response.body
