如何用 Python 解决 从图中获取坐标

#pip3 install anticaptchaofficial

from anticaptchaofficial.imagetocoordinates import *

solver = imagetocoordinates()
solver.set_verbose(1)
solver.set_key("YOUR_KEY")
solver.set_mode("points")
solver.set_comment("Select objects in specified order")

coordinates = solver.solve_and_return_solution("coordinates.png")
if coordinates != 0:
    print("coordinates: ", coordinates)
else:
    print("task finished with error "+solver.error_code)

如何用 Node.js 解决 从图中获取坐标

//npm install @antiadmin/anticaptchaofficial
//https://github.com/anti-captcha/anticaptcha-npm

const ac = require("@antiadmin/anticaptchaofficial");
const fs = require('fs');

const captcha = fs.readFileSync('captcha.png', { encoding: 'base64' });

ac.setAPIKey('YOUR_API_KEY_HERE');

//Specify softId to earn 10% commission with your app.
//Get your softId here: https://anti-captcha.com/clients/tools/devcenter
ac.setSoftId(0);

ac.solveImageToCoordinates(captcha, "Select all objects in specified order", "points")
    .then(coordinates => console.log('image coordinates:', coordinates))
    .catch(error => console.log('test received error '+error));

如何用 Go 解决 从图中获取坐标

// Install with:
// go get github.com/anti-captcha/anticaptcha-go

package main

import (
    "encoding/base64"
    "fmt"
    "github.com/anti-captcha/anticaptcha-go"
    "log"
)

func main() {
    // Create API client and set the API Key
    ac := anticaptcha.NewClient("API_KEY_HERE")

    // set to 'false' to turn off debug output
    ac.IsVerbose = true

    // Specify softId to earn 10% commission with your app.
    // Get your softId here: https://anti-captcha.com/clients/tools/devcenter
    //ac.SoftId = 1187

    // Make sure the API key funds balance is positive
    balance, err := ac.GetBalance()
    if err != nil {
        log.Fatal(err)
        // Exit program to make sure you don't DDoS API with requests, while having empty balance
        return
    }
    fmt.Println("Balance:", balance)

    // Solve image-to-coordinates captcha
    imageData, err := ac.ReadImageFile("coordinates.jpg")
    if err != nil {
        log.Fatal(err)
    }
    solution, err := ac.SolveImageToCoordinates(base64.StdEncoding.EncodeToString(imageData), anticaptcha.ImageToCoordinates{
        Comment: "Select object in the specified order",
        Mode:    "points",
    })
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println("Objects X,Y coordinates:", solution)
}

如何用 PHP 解决 从图中获取坐标

//git clone https://github.com/anti-captcha/anticaptcha-php.git

include("../anticaptcha.php");
include("../imagetocoordinates.php");

$api = new ImageToCoordinates();
$api->setVerboseMode(true);

//your anti-captcha.com account key
$api->setKey(readline("You API key: "));

//setting file
$api->setFile("captcha.jpg");
$api->setComment("Select all elephants");
$api->setMode("rectangles");

//Specify softId to earn 10% commission with your app.
//Get your softId here: https://anti-captcha.com/clients/tools/devcenter
$api->setSoftId(0);

if (!$api->createTask()) {
    $api->debout("API v2 send failed - ".$api->getErrorMessage(), "red");
    return false;
}

$taskId = $api->getTaskId();


if (!$api->waitForResult()) {
    $api->debout("could not solve captcha", "red");
    $api->debout($api->getErrorMessage());
} else {
    $coordinates    =   $api->getTaskSolution();
    echo "\nresult:\n";
    print_r($coordinates);
    //check result, then if results is wrong:
    $api->reportIncorrectImageCaptcha();
}

如何用 bash 解决 从图中获取坐标

curl -i -H "Accept: application/json" \
-H "Content-Type: application/json" \
-X POST -d '{
    "clientKey":"YOUR_API_KEY_HERE",
    "task":
        {
            "type":"ImageToCoordinatesTask",
            "body":"BASE64_BODY_HERE__NO_NEWLINES__NO_EXTRA_TAGS__ONLY_CLEAN_BASE64",
            "comment":"Select all elephants",
            "mode":"rectangles"
        },
    "softId": 0
}' https://api.anti-captcha.com/createTask

任务对象

属性 类型 必须使用 用途
type 字符串 ImageToCoordinatesTask
指定任务类型。
body 字符串 文件主体以 base64 格式编码。一定要在没有换行符的情况下发送文件主体。不要包括“data:image/png”或类似的标记,仅使用纯净的 base64 格式!
comment 字符串 仅用英文字符对任务添加的备注。示例:“Select objects in specified order”或“select all cars”。
mode 字符串 任务模式,可以是“points”或“rectangles”。默认设置是“points”。
websiteURL 字符串 自愿使用的参数,用于在支出统计数据中区分图片人机验证谜题来源。

任务处理结果对象

属性 类型 用途
coordinates 字符串 一些坐标的数组。对于“点”模式,数组为 (x,y) 集。对于“矩形”模式,数组为 (x1,y1,x2,y2),从左上角到右下角。坐标从左上角开始。
