Httpful is a simple Http Client library for PHP 7.2+. There is an emphasis of readability, simplicity, and flexibility – basically provide the features and flexibility to get the job done and make those features really easy to use.
Features
- Readable HTTP Method Support (GET, PUT, POST, DELETE, HEAD, PATCH and OPTIONS)
- Custom Headers
- Automatic "Smart" Parsing
- Automatic Payload Serialization
- Basic Auth
- Client Side Certificate Auth
- Request "Templates"
aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. It provides a simple API for making HTTP requests and handling both client and server functionality. Like the requests package, aiohttp is designed to be easy to use and handle many of the low-level details of working with HTTP.
The main benefit of aiohttp over requests is that it is built on top of the asyncio library, which means that it can handle many requests at the same time without blocking the execution of your program. This can lead to significant performance improvements when making many small requests, or when dealing with slow or unreliable network connections.
aiohttp provides both client and server side functionality, so you can use it to create web servers and handle client requests in a non-blocking manner. It also supports WebSocket protocol, so it can be used for building real-time application like chat, game, etc.
aiohttp also provide several features for handling connection errors, managing timeouts, and client sessions. It also provide similar features like requests package like redirect handling, cookies, and support for several authentication modules.
You can install aiohttp via pip package manager:
pip install aiohttp
In terms of API design, aiohttp is similar to requests and thus should be familiar to anyone who has used the requests library, but it provides an async with block to manage the context of the connection and used await statement to wait for the result.
It''s worth noting that aiohttp is built on top of asyncio and is designed to be used in Python 3.5 and above. It provides the same functionality as httpx but it is specifically built for the asyncio framework.
Highlights
Example Use
require 'vendor/autoload.php';
use Httpful\Request;
// make GET request
$response = \Httpful\Request::get("http://httpbin.org/get")
->send();
echo $response->body;
// make POST request
$data = array('name' => 'Bob', 'age' => 35);
$response = \Httpful\Request::post("http://httpbin.org/post")
->sendsJson()
->body(json_encode($data))
->send();
echo $response->body;
// add headers or cookies
$response = \Httpful\Request::get("http://httpbin.org/headers")
->addHeader("API-KEY", "mykey")
->addHeader("Cookie", "foo=bar")
->send();
echo $response->body;
import asyncio
from aiohttp import ClientSession, WSMsgType
# aiohttp only provides async client so we must use a coroutine:
async def run():
async with ClientSession(headers={"User-Agent": "webscraping.fyi"}) as session:
# we can use the session to make requests:
response = await session.get("http://httpbin.org/headers")
print(response.status)
# note: to read the response body we must use await:
print(await response.text())
# aiohttp also comes with convenience methods for common requests:
# POST json
resp = await session.post("http://httpbin.org/post", json={"key": "value"})
# POST form data
resp = await session.post("http://httpbin.org/post", data={"key": "value"})
# decode response as json
resp = await session.get("http://httpbin.org/json")
data = await resp.json()
print(data)
# aiohttp also supports websocket connections
# which can be used to scrape websites that use websockets:
async with session.ws_connect("http://example.org/ws") as ws:
async for msg in ws:
if msg.type == WSMsgType.TEXT:
if msg.data == "close cmd":
await ws.close()
break
else:
await ws.send_str(msg.data + "/answer")
elif msg.type == WSMsgType.ERROR:
break
asyncio.run(run())
