騰訊滑塊驗證碼識別和加速度模擬(1)

騰訊滑塊驗證碼識別

騰訊滑塊驗證碼識別,識別凹槽的x軸位置，mock滑塊的加速度

安裝python環境

參考：https://janikarhunen.fi/how-t...

sudo yum install https://centos7.iuscommunity.org/ius-release.rpm
sudo yum install python36u
python3.6 -V
sudo yum install python36u-pip
sudo yum install python36u-devel

創建環境 Creating a virtualenv

python3.6 -m venv venv
. venv/bin/activate
pip install [package_name]
pip install -r requirements.txt

daemonize 運行

# 參考 https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uswgi-and-nginx-on-ubuntu-18-04
# Install the latest stable release:
pip install uwsgi
# ... or if you want to install the latest LTS (long term support) release,
pip install https://projects.unbit.it/downloads/uwsgi-lts.tar.gz

# 創建ln 
cp captcha.service /etc/systemd/system/captcha.service
systemctl enable captcha.service
systemctl start captcha.service

uwsgi --ini /usr/local/nginx/html/myblog/uwsgiconfig.ini

#後臺運行
uwsgi --ini /usr/local/nginx/html/myblog/uwsgiconfig.ini --daemonize /usr/local/nginx/html/myblog/myblog.out

是用nginx做代理

在nginx部分做一個代理

        location /tx/ {
            add_header Access-Control-Allow-Origin *;
            include        uwsgi_params;
            uwsgi_pass     127.0.0.1:8008;
        }

訪問api

請求圖片識別和加速度模擬

http://127.0.0.1:5000/tx/image

POST /tx/image HTTP/1.1
Host:host
Content-Type: application/json
Accept: */*
Cache-Control: no-cache
Accept-Encoding: gzip, deflate

{
    "url": "圖片的地址"
}

返回數據

{
    "data": {
        "list": [],//模擬的點
        "url": "",//圖片地址
        "x": 515,// x軸的偏移量
    },
    "message": "解析成功"
}

模擬瀏覽器移動

            const slider = {width: 680, point: 0, move: 0, steps: 0, posX: 0};//原本的高度
            //開始計算移動的距離
            slider.point = bgSize.width / slider.width * x;
            slider.move = handle.x + slider.point - 5;
            slider.steps = Math.random() * 100 / 30 + 100;
            slider.posX = handle.x + handle.width / 2;

            logger.info(`開始識別和移動滑塊`, slider);

            //滑塊的位置
            await page.mouse.move(slider.posX, handle.y + handle.height / 3, {steps: slider.steps});
            await page.mouse.down();
            let val = handle.x;
            for (let i = 0; i < traces.length; i++) {
                val += bgSize.width / slider.width * (traces[i]);//縮放距離
                slider.move = val;
                if (val <= slider.posX) continue;
                await page.mouse.move(slider.move, handle.y + handle.height / 2 + 5);
            }
            await page.waitFor(100);
            await page.mouse.up();

驗證碼識別成功後悔返回驗證識別結果的Ticket
