高德地图滑动验证

高德地图滑动验证

• 用dispatch 模拟dom的mousedown, mousemove，还有mouseUp 事件
• 再用 setInterval 执行mouseMove事件即可
• 但这里有时候会滑动失败，所以要刷新验证码，然后重新滑动，
• 有时候又是滑动验证码验证成功后。 再一次弹出验证码
• 注意：滑动验证码请注意滑动的速度和滑动的距离，要是太慢、滑动距离太短的话，滑动验证多数会不通过。

检查验证码

// 检查验证码
function checkYzm() {
    const dom = document.querySelector(".sufei-dialog");

    if(dom && dom.style.display == "block") {
        return true;
    } 
    return false
}

滑动验证码

async function sliderYzm() {
    await sleep(1500);
    const iframe = document.getElementById("sufei-dialog-content");
    const btn = iframe.contentWindow.document.getElementById("nc_1_n1z");
    const mousedown = document.createEvent("MouseEvents");
    const rect = btn.getBoundingClientRect();
    var x = rect.x;
    var y = rect.y;
    mousedown.initMouseEvent("mousedown", true, true, window, 0, x, y, x, y, false, false, false, false, 0, null);
    btn.dispatchEvent(mousedown);

    let dx = 0;
    let dy = 0;
    const mousemove = document.createEvent("MouseEvents");
    return new Promise((resolve) => {
        const  interval = setInterval(async () => {
            const _x = x + dx;
            const _y = y + dy;
            mousemove.initMouseEvent("mousemove", true, true, window,0 ,_x, _y, _x, _y, false, false, false, false, 0, null);
            btn.dispatchEvent(mousemove);

            if(_x - x >= 300){
                clearInterval(interval);
                const mouseup = document.createEvent("MouseEvents");
                mouseup.initMouseEvent("mouseup", true, true, window, 0, _x, _y, _x, _y, false, false, false, false, 0, null);
                btn.dispatchEvent(mouseup);

                await sleep(2500);
                if(btn.className.indexOf('btn_ok') > -1){
                    console.log(btn.className);
                    sleep(1000)
                    resolve({status: 1});
                }  

                if(iframe.contentWindow.document.querySelector("#nocaptcha > .errloading")) {
                    console.log("error")
                    sleep(1000)
                    resolve({status: 0})
                }
            } else{
                dx += Math.ceil(Math.random() * 300);
            }
        }, 30);
    })

}

上面只是滑动验证

循环检查时候是否有验证码

/**
 * 循环检查是否有验证码
 * 1. 要是有验证码窗口，那么滑动验证， 但滑动验证有失败或者成功，失败返回0， 成功返回1
 * 2. 滑动成功后，防止验证码再一次出现，我们延迟1500毫秒，再查看一下验证码窗口是否存在，存在就再一次执行loopSlideYzm(), 不存在就直接结束函数了
 * 3. 滑动失败后，会有刷新标志，那这时候应该点击刷新后，再一次执行loopSlideYzm();
 */ 
async function loopSlideYzm() {
    await sleep(1200);
    const hasYzm = checkYzm();
    await sleep(1000);
    if(hasYzm) {
        const { status } = await sliderYzm();
        await sleep(1500);
        if(status) {
            console.log("再找一次是否有验证码")
            const hasYzmAgain = checkYzm();
            await sleep(1500);
            if(hasYzmAgain) {
                return await loopSlideYzm();
            } else  {
                return Promise.resolve()
            }
        } else {
            console.log("给我刷新验证码");
            freshYzm();
            await sleep(1500);
            return await loopSlideYzm();
        }
    } 
    return Promise.resolve()
}

刷新验证码

function freshYzm() {
    const iframe = document.getElementById("sufei-dialog-content");
    iframe.contentWindow.document.querySelector("#nocaptcha > .errloading > .nc-lang-cnt > a").click()
}

以上就是自动跳过高德地图的滑动验证码全过程
