# Example for solving of GeeTest Captcha in JavaScript using Puppeteer library



# Description

This example clearly shows how you can automate the GeeTest captcha solution. In the example, the captcha is bypassed on the [demo page](https://2captcha.com/demo/geetest), but the principle of bypassing the captcha is similar everywhere.



## How to start

### Cloning:

`git clone https://github.com/dzmitry-duboyski/GeeTest-demo.git`



### Installing dependencies:

`npm install`



### Set your apikey in `.env` file



### Start:

`npm run start`

>[GeeTest](https://www.geetest.com/) security platform is used on many popular sites. In this manual, it is described how to successfully undergo a [GeeTest](https://www.geetest.com/) security check using service [2Captcha.com](https://2captcha.com/?from=16653706) and [Puppeteer](https://pptr.dev/). For a successful check of the [GeeTest](https://www.geetest.com/) captcha, you must have an account in the [2Captcha.com](https://2captcha.com/?from=16653706) service.



This example describes how to solve captcha GeeTest on the demo page [https://2captcha.com/demo/geetest](https://2captcha.com/demo/geetest?from=16653706).



## Description of the GeeTest solution algorithm:

1. Find captcha parameters `gt`, `challenge`, `api_server`:



    1.1. You can find the value of `gt` in the page code.

    Screenshot:

    ![the gt value in the page code](./screenshot/gt_value.png)



    1.2 Finding the meaning of `challenge` is a bit more difficult. 

    To do this, you need to find the request that the captcha makes on this page, this request must contain the value `challenge`.



    The response to the request will be in the following format:

    `{"success":1,"challenge":"21aaa1c62221631516179b492b9e80cc","gt":"81388ea1fc187e0c335c0a8907ff2625"}`. From this answer, you need to take the value `challenge`. 



    >If we consider the example with a captcha on the page [https://2captcha.com/demo/geetest](https://2captcha.com/demo/geetest?from=16653706), then in this case it will be a request to https://2captcha.com/api/v1/captcha-demo/gee-test/. The response to this request contains the required `challenge'.

    >Response: `{"success":1,"challenge":"21aaa1c62221631516179b492b9e80cc","gt":"81388ea1fc187e0c335c0a8907ff2625"}`.

    You can read more about the `challenge` on the [page](https://2captcha.com/p/geetest?from=16653706).



2. Sending captcha to API.



To solve the captcha, you need to send the found captcha parameters to the API:

```json

"key":"your_api_key",

"method":"geetest"

"pageurl":"https://2captcha.com/demo/geetest"

"gt": "81388ea1fc187e0c335c0a8907ff2625",

"challenge": "21aaa1c62221631516179b492b9e80cc"

```



3. Getting a answer for Captcha.



After successfully solving the captcha, the API will return a response with the solution. Example of a response with a solution from the API:

```json

{

   "status": 1,

   "request": {

       "geetest_challenge": "fd4847c8a368356a0e3a6636392c2854k9",

       "geetest_validate": "4606cdf89c8c2e5a43c5a14fe475fc40",

       "geetest_seccode": "4606cdf89c8c2e5a43c5a14fe475fc40|jordan"

   }

}

```



4. Using the solution.

The resulting values must be inserted into the corresponding html elements of the GeeTest captcha on the page.



Example:

```html



  

  

  



```



Screenshot:

Done. After that, you can proceed to perform actions on the page. In this example, after that, the "Check" button is clicked.
