How to solve Tencent captcha on hjd2048.com

Introduction

This guide is for developers who are integrating Tencent captcha bypass (QCloud Captcha, Turing Captcha) via the 2Captcha API. We will cover the request structure, required parameters, and provide working JSON examples for the site hjd2048.com.

What you will need:

• API key from 2Captcha
• appId value from the target site
• Full URL of the page with the captcha
• If needed, a link to the captcha script captchaScript

1. About Tencent Captcha

1.1. Technology Overview

Tencent Captcha is a tokenized protection system that uses interactive tasks: slider puzzle, point selection, or simple verification. After successful solving, the server returns a token (ticket + randstr) that must be passed to the form or request to the target site.

1.2. Task Types

1.3. Required and Optional Parameters

2. Data Preparation

2.1. Getting the appId

1. Open the target page in your browser
2. Press F12, go to the Elements tab
3. Find the element with attribute data-aid or appId:

<div id="tcaptcha-widget" data-aid="189997505"></div>

The value 189997505 is your appId.

2.2. Finding captchaScript (if needed)

If the standard request returns ERROR_CAPTCHA_UNSOLVABLE, add the captchaScript parameter:

1. In DevTools, open the Network tab
2. Refresh the page, apply the captcha filter
3. Find the request to cap_union_prehandle or loading of a .js file
4. Copy the full script URL, for example:

https://global.captcha.gtimg.com/TCaptcha-global.js

3. Building the Request

3.1. API Endpoints

3.2. Example Request for hjd2048.com (TencentTaskProxyless)

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "TencentTaskProxyless",
    "appId": "189997505",
    "websiteURL": "https://hjd2048.com/2048/",
    "captchaScript": "https://global.captcha.gtimg.com/TCaptcha-global.js"
  }
}

3.3. Example Request with Proxy (TencentTask)

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "TencentTask",
    "appId": "189997505",
    "websiteURL": "https://hjd2048.com/2048/",
    "captchaScript": "https://global.captcha.gtimg.com/TCaptcha-global.js",
    "proxyType": "http",
    "proxyAddress": "1.2.3.4",
    "proxyPort": 8080,
    "proxyLogin": "user23",
    "proxyPassword": "p4$w0rd"
  }
}

4. Getting and Using the Result

4.1. Requesting the Result

Send a POST request to https://api.2captcha.com/getTaskResult:

{
  "clientKey": "YOUR_API_KEY",
  "taskId": 74455221488
}

4.2. Example Successful Response

{
  "errorId": 0,
  "status": "ready",
  "solution": {
    "appid": "189997505",
    "ret": 0,
    "ticket": "tr0344YjJASGmJGtohyWS_y6tJKiqVPIdFgl87vWlVaQoueR8D6DH28go-i-VjeassM31SXO7D0*",
    "randstr": "@KVN"
  },
  "cost": "0.00299",
  "createTime": 1692863536,
  "endTime": 1692863556,
  "solveCount": 1
}

4.3. Applying the Token on the Target Site

The received ticket and randstr must be passed to the callback function defined during captcha initialization:

// Example initialization on the target site
const myCallbackFunction = (token) => {
    // Token verification on the site backend
}
var captcha = new TencentCaptcha('189997505', myCallbackFunction, {});
captcha.show();

// After receiving the solution from 2Captcha:
let res = JSON.parse(apiResponse);
myCallbackFunction(res.solution);

If the site expects the token in a form, add hidden fields:

<input type="hidden" name="ticket" value="tr0344...">
<input type="hidden" name="randstr" value="@KVN">

5. Alternative Methods

5.1. Coordinates Method for Point Selection Captchas

If the standard method does not work, use a task of type Coordinates:

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "Coordinates",
    "imageUrl": "https://ca.turing.captcha.qcloud.com/captcha-image.png",
    "question": "Click on the same animals"
  }
}

The response contains a string with coordinates:

{
  "solution": {
    "coordinates": "150,200;300,150;450,300"
  }
}

5.2. Handling ERROR_CAPTCHA_UNSOLVABLE Error

6. Common Errors

6.1. Error Reporting

If the solution fails validation on the target site, send a report:

Incorrect solution:

GET https://api.2captcha.com/reportbad?key=YOUR_API_KEY&id=TASK_ID

Correct solution (must be sent together with reportbad):

GET https://api.2captcha.com/reportgood?key=YOUR_API_KEY&id=TASK_ID

7. Additional Resources

• Sandbox: enable mode - test requests without code
• API Documentation: Tencent Captcha - full method description
• Examples on GitHub: 2captcha/2captcha-node
• Error Reporting: reportgood/reportbad
• Support: create a ticket

8. Checklist

• API key obtained and verified from 2Captcha account dashboard
• Correct appId extracted from the target page source code
• Full websiteURL of the captcha page specified
• For non-standard implementations, added captchaScript parameter
• Suitable task type selected: TencentTaskProxyless or TencentTask
• Request tested via sandbox or with a small budget
• Logic for applying token (ticket + randstr) on target site implemented
• Sending reportgood/reportbad configured for quality control

Conclusion

Tencent captcha requires accurate transmission of appId and websiteURL parameters. For non-standard implementations, it is critical to specify the captchaScript parameter, its absence often leads to the ERROR_CAPTCHA_UNSOLVABLE error.

Use task type TencentTaskProxyless for standard cases and TencentTask with proxy if the site uses geo-blocking. Pass the received token (ticket + randstr) to the callback function or to the target site form according to its documentation.

If problems occur, check the captcha script link for freshness and send reports via reportbad/reportgood if needed, this helps improve solution quality and get refunds for incorrect answers.
