wulu-geetest-bypass

English | 简体中文

A lightweight, pure Python library to automatically solve Geetest Behavioral CAPTCHA v4 without Node.js or headless browsers. Features dynamic mouse trajectory simulation, 7 built-in risk type solvers, accessible voice bypass, and an extensible custom solver registry.

✨ Features

• 🚀 Pure Python 3.11+ — Zero Node.js, headless browsers, or external runtime dependencies required.
• 🛡️ Multi-Risk Type Support — Out-of-the-box solvers for 7 risk types (see full table).
• 🎯 Human-like Track Simulation — Dynamically generated mouse trajectories for every run (no fixed replays).
• 🔁 Smart Auto-Retry — One-call resolve() automatically retries up to 3 times on transient failures.
• 🕹️ Granular Step-by-Step Flow — Separate load() and verify() steps for intercepting payloads and tokens.
• ♿ Accessible Voice Bypass — Seamlessly switch to offline speech recognition when the voice channel is enabled.
• 🔌 Extensible Solver Registry — Easily plug in custom OCR / Vision models, or override built-in solvers.
• 🌐 Advanced Networking — Native support for proxy chains, browser TLS fingerprint emulation, and custom headers.

🧩 Supported Risk Types

The Dependency column refers to the dependency groups below. Types marked ❌ have no built-in solver — register your own via custom solvers.

📦 Installation

uv is recommended (faster, more modern Python package manager):

uv add "wulu-geetest-bypass[all]"

You can also use pip:

pip install "wulu-geetest-bypass[all]"

Dependency groups (install only what you need):

# voice verification
uv add "wulu-geetest-bypass[voice]"

# slide puzzle (requires opencv)
uv add "wulu-geetest-bypass[slide]"

# SVG icon & seed selection
uv add "wulu-geetest-bypass[svg]"

# Install everything
uv add "wulu-geetest-bypass[all]"

🚀 Quick Start

import asyncio
from wulu_geetest_bypass import Geetest


async def main():
    g = Geetest(captcha_id='your_captcha_id', risk_type='slide')
    result = await g.resolve()
    print(result)
    # {
    #     "captcha_id": "xxx",
    #     "lot_number": "xxx",
    #     "pass_token": "xxx",
    #     "gen_time": "xxx",
    #     "captcha_output": "xxx"
    # }


asyncio.run(main())

That is all you need for the common case. See Advanced Usage for retry control, the step-by-step flow, voice mode, custom solvers, and HTTP configuration.

💡 Advanced Usage

Automatic retry and one-call resolve()

resolve() is load() + verify() in one call, with automatic retry on failure:

g = Geetest(captcha_id='your_captcha_id', risk_type='slide')
result = await g.resolve()  # default: up to 3 attempts
result = await g.resolve(retry=5)  # override the attempt count

On the final failure it raises VerifyError instead of returning a partial result.

Step-by-step flow: load() → verify()

When you need to intervene between the two stages (log, inspect the payload, run your own recognition), call them separately:

g = Geetest(captcha_id='your_captcha_id', risk_type='slide')
data = (
    await g.load()
)  # init data: captcha_type, lot_number, payload, process_token, pow_detail, ...
response = await g.verify(data)  # full response: status + data

load() returns a dict whose fields can be passed directly into verify(). The return types are listed under Data Models.

Accessible (voice) mode

Some Geetest v4 sites enable the voice channel (accessible mode) server-side. When a site supports it, regardless of the original risk type, you can force voice verification via voice=True, bypassing the original slider / click behavioral checks:

# Originally a slide verification, but the site supports accessible mode
g = Geetest(captcha_id='your_captcha_id', risk_type='slide', voice=True)
result = await g.resolve()

The flow becomes: load voice captcha → download audio → recognize digits offline → submit verification. No browser environment or image recognition needed.

Note: Not all sites enable the accessible channel. If unsupported, the show_voice field in load() returns false, and setting voice=True has no effect — the original risk_type is still used.

Register custom solvers

For risk types without built-in support, inject a custom solver via register_solver:

from wulu_geetest_bypass import Geetest


def solve_icon(imgs: bytes, ques: list[bytes]) -> list[tuple[float, float]]: ...


Geetest.register_solver('icon', solve_icon)

Once registered, generate_w() calls it automatically with the corresponding payload fields. Click/draw solvers return normalized coordinates in [0, 1] relative to the verification image — the library takes care of scaling them to the window/payload formats (e.g. userresponse uses image-based percent × 10000) and of generating the click tracks (including the final submit-button click for icon/word/phrase):

Built-in solvers can also be overridden, either by passing the solver directly or as a decorator:

Geetest.register_solver('slide', my_custom_slide_solver)

@Geetest.register_solver('slide')
def my_custom_slide_solver(bg, slice, ypos): ...

Proxy and HTTP client configuration

Geetest forwards all HTTP concerns to wreq, so proxies, custom headers, and client emulation are configured once at construction time. Pass a ClientConfig via client_options, or an already-constructed client via client (which takes priority):

from wreq import Client, ClientConfig

config = ClientConfig(...)  # proxy chains, headers, emulation, timeouts, ...

g = Geetest(captcha_id='your_captcha_id', risk_type='slide', client_options=config)
# equivalent, when you need to build the client yourself first:
g = Geetest(captcha_id='your_captcha_id', risk_type='slide', client=Client(config))

📖 API Reference

Configuration — Geetest(**options)

Data models

load() -> dict returns init data containing captcha_type, lot_number, payload, process_token, pow_detail and other fields, passable directly into verify().

verify(data) -> VerifyResponse:

class VerifyResponse:
    status: str  # "success" / "error"
    data: VerifyData  # VerifyDataSuccess | VerifyDataFail, discriminated by `result`


class VerifyDataSuccess:  # result == "success"
    lot_number: str
    result: str
    fail_count: int
    seccode: Seccode  # success only
    score: str
    payload: str
    process_token: str
    payload_protocol: int


class VerifyDataFail:  # result == "fail" / "forbidden" / "continue" — no seccode
    lot_number: str
    result: str
    fail_count: int
    score: str
    payload: str
    process_token: str
    payload_protocol: int

resolve(retry=3) -> Seccode:

class Seccode:
    captcha_id: str
    lot_number: str
    pass_token: str
    gen_time: str
    captcha_output: str

Exceptions

VerifyError.result is the raw server value: fail (scored and rejected — wrong answer, bad headers or low risk score; retryable), forbidden (rejected before scoring — an IP-level rate limit, not an answer problem; back off or change the exit IP) or continue (another round of the same challenge is wanted, match only).
