python-cronet is a library to use Chromium's network stack from Python.
The library is currently in alpha stage.
Cronet is the networking stack of Chromium put into a library for use on Android. It offers an easy-to-use, high performance, standards-compliant, and secure way to perform HTTP requests.
The Chromium team also provides a native version of the library(not officially supported) which allows you to use it in desktop/server operating systems like Linux, macOS and Windows.
The main benefits of using cronet as an HTTP client are:
- You get to use the same high quality code that runs on Chromium.
- Support for the latest protocols like QUIC and compression formats.
- Concurrency support by performing asynchronous requests.
- Has the same TLS fingerprint as Chrome, meaning that Cloudflare and other bot detection systems can't block your requests based on it.
- It's much more lightweight on system resources compared to headless Chrome(although it doesn't support executing javascript).
For the time being the only supported platform is linux-x86-64. The plan is to also support windows and macOS.
pip install python-cronet
The library provides an asynchronous API:
import asyncio
import cronet
async def main():
with cronet.Cronet() as cr:
# GET request
response = await cr.get("https://httpbin.org/get")
print(f"GET request: {response.url}, {response.status_code}")
print(f"Response JSON: {response.json()}")
# GET request with query parameters
params = {"param1": "value1", "param2": "value2"}
response = await cr.get("https://httpbin.org/get", params=params)
print(f"GET request with params: {response.url}, {response.status_code}")
print(f"Response JSON: {response.json()}")
# POST request with form data
data = {"key1": "value1", "key2": "value2"}
response = await cr.post("https://httpbin.org/post", data=data)
print(f"POST request: {response.url}, {response.status_code}")
print(f"Response JSON: {response.json()}")
# PUT request with JSON data
json_data = {"key1": "value1", "key2": "value2"}
response = await cr.put("https://httpbin.org/put", json=json_data)
print(f"PUT request: {response.url}, {response.status_code}")
print(f"Response JSON: {response.json()}")
# PATCH request with custom headers
headers = {"X-Custom-Header": "MyValue"}
response = await cr.patch("https://httpbin.org/patch", headers=headers)
print(f"PATCH request: {response.url}, {response.status_code}")
print(f"Response JSON: {response.json()}")
# DELETE request
response = await cr.delete("https://httpbin.org/delete")
print(f"DELETE request: {response.url}, {response.status_code}")
print(f"Response JSON: {response.json()}")
asyncio.run(main())
