木偶组织对PuppeteerSharp的作用

Question

我是新来的木偶夏普和木偶技师一般。我正在尝试将木偶师中使用的函数转换为puppeteerSharp，并且我想知道如何做到这一点。下面是木偶师的功能(这个函数向下滚动到页面的末尾)：

async function autoScroll(page){
await page.evaluate(async () => {
    await new Promise((resolve, reject) => {
        var totalHeight = 0;
        var distance = 100;
        var timer = setInterval(() => {
            var scrollHeight = document.body.scrollHeight;
            window.scrollBy(0, distance);
            totalHeight += distance;

            if(totalHeight >= scrollHeight){
                clearInterval(timer);
                resolve();
            }
        }, 100);
    });
});

任何人都可以告诉我，我怎样才能让它与puppeteerSharp一起工作呢？亲切的问候

您可以调用EvaluateFunctionAsync并将该函数传递为string。

await page.EvaluateFunctionAsync(@"async () => {
    await new Promise((resolve, reject) => {
        var totalHeight = 0;
        var distance = 100;
        var timer = setInterval(() => {
            var scrollHeight = document.body.scrollHeight;
            window.scrollBy(0, distance);
            totalHeight += distance;

            if(totalHeight >= scrollHeight){
                clearInterval(timer);
                resolve();
            }
        }, 100);
    });
}");
