我想在页面加载不正确或遇到问题时重新加载页面。我试过了,page.reload()但没有用。
for(const sect of sections ){
// Now collect all the URLs
const appUrls = await page.$$eval('div.main > ul.app-list > li > div.app-info a.app-info-icon', links => links.map(link => link.href));
// Visit each URL one by one and collect the data
for (let appUrl of appUrls) {
var count = i++;
try{
await page.goto(appUrl);
const appName = await page.$eval('div.det-name-int', div => div.innerText.trim());
console.log('\n' + count);
console.log(appName);
} catch(e){
console.log('\n' + count);
console.log('ERROR', e);
await page.reload();
}
}
}

它给了我这个错误: …
我想知道如何比较列表中的日期。我想提取“最早”的日期。(我做了一个 for 循环,因为我必须用“-”替换一些字符)
comment_list = comment_container.findAll("div", {"class" : "comment-date"})
D =[]
for commentDate in comment_list:
year, month, day = map(int, commentDate.split('-'))
date_object = datetime(year, month, day)
date_object = datetime.strptime(commentDate, '%Y-%m-%d').strftime('%Y-%m-%d')
D.append(date_object)
print(D)
