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.

Buzz is a lightweight PHP library for issuing HTTP requests. It is built on top of the PHP curl extension and is designed to be easy to use and flexible.

While buzz isn't as feature rich as other clients it still supports http2 and is relatively easy to use.

Example Use

```python 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())) ``` ```

```php use Buzz\Client\Curl; use Buzz\Message\Request; use Buzz\Message\Response; $client = new Curl(); // GET request $request = new Request('GET', 'http://httpbin.org/get'); $response = new Response(); $client->send($request, $response); echo $response->getContent(); //POST request $request = new Request('POST', '/api/resource', 'http://example.com'); $request->setContent(json_encode(['name' => 'John Doe'])); // we can also add headers or cookies: $request->addHeader('Content-Type: application/json'); $request->addHeader('Cookie: name=foobar'); $response = new Response(); $client->send($request, $response); echo $response->getContent(); // Buzz also supports http2 (see the 2.0 parameter) $response = $client->sendRequest( new Request('GET', 'https://http2.golang.org/serverpush', [], null, '2.0') ); ```
