Curl-impersonate is a special build of libcurl and cURL HTTP client that impersonates the four major browsers: - Google Chrome - Microsoft Edge - Safari - Firefox Curl-impersonate achieves this by patching TLS and HTTP fingerprints to be identical to that of one of these real browsers.

Unlike other HTTP clients curl-impersonate can bypass TSL and HTTP fingerprinting and detection techniques though it does not implement anything for Javascript fingerprint or bypass.

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.

Example Use


curl-impersonate installs itself under `curl_` terminal commands like `curl_chrome116`: ```shell $ curl_chrome116 https://www.wikipedia.org ``` To use it in HTTP client libraries that use `libcurl` replace curl path with one of these. To use it in python directly see curl-cffi Python package
```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())) ``` ```
