flaresolverr-session 0.1.2

A requests.Session that proxies through a FlareSolverr instance.

FlareSolverr Session

A requests.Session that transparently routes all HTTP requests through a FlareSolverr instance, allowing you to bypass Cloudflare protection with a familiar Python API.

This project is not responsible for solving challenges itself, it only forwards requests to FlareSolverr. If FlareSolverr fails to solve a challenge, it will raise an exception. Any issues related to challenge solving should be reported to the FlareSolverr project.

Installation

pip install flaresolverr-session

Prerequisites

You need a running FlareSolverr instance. The quickest way is via Docker:

docker run -d --name=flaresolverr -p 8191:8191 ghcr.io/flaresolverr/flaresolverr:latest

Usage

Basic Usage

from flaresolverr_session import Session

with Session("http://localhost:8191/v1") as session:
    response = session.get("https://example.com")
    print(response.status_code)
    print(response.text)

It is recommended to set a persistent session_id.

session = Session(
    "http://localhost:8191/v1",
    session_id="my-persistent-session",
)

Command-Line Interface

After installation, you can use the flaresolverr-session command:

flaresolverr-session https://example.com -f http://127.0.0.1:8191/v1 -o output.html

If the FlareSolverr URL is not provided, it will look for the FLARESOLVERR_URL environment variable.

You can also run the CLI without an output option to see the challenge-solving results in the console.

Response Object

A FlareSolverr object is attached to the response as response.flaresolverr. It contains metadata about the request and challenge solving process returned by FlareSolverr.

Attribute	Description
flaresolverr.status	"ok" on success
flaresolverr.message	Message from FlareSolverr (e.g. challenge status)
flaresolverr.user_agent	User-Agent used by FlareSolverr's browser
flaresolverr.start / flaresolverr.end	Request timestamps (ms)
flaresolverr.version	FlareSolverr server version

Exception Handling

Exception	Description
FlareSolverrError	Base exception. Inherits from requests.exceptions.RequestException.
FlareSolverrChallengeError	Challenge could not be solved.
FlareSolverrCaptchaError	CAPTCHA detected. Inherits from FlareSolverrChallengeError.
FlareSolverrTimeoutError	Request timed out.
FlareSolverrSessionError	Session creation/destruction failed.
FlareSolverrUnsupportedMethodError	Unsupported HTTP method or content type.

Limitations

• Only GET and application/x-www-form-urlencoded POST are supported. Otherwise, it will raise FlareSolverrUnsupportedMethodError.
• Headers returned by FlareSolverr may be empty for some sites, depending on the FlareSolverr version and configuration. Empty HTTP status will be regarded as 200. See FlareSolverr#1162.
