我正在尝试使用Axios + Cheerio从网页中提取数据。我得到了想要的数据,但是只能通过console.log(array)输出*在功能内*如何从外部访问数据?
const axios = require('axios');
const cheerio = require('cheerio');
const url = 'https://abcdefg.com/'
axios.defaults.withCredentials = true
const getip = (callback) => {
axios(url, {
headers: {
Cookie: "x=xx;"
}
})
.then(response => {
const html = response.data;
const $ = cheerio.load(html);
// Deals Page
const statsTable = $('tbody > tr');
const totaldeals = [];
// Loop Table for data in each row
statsTable.each(function () {
const nwline = "\n"
let date = $(this).find('td:nth-child(1)').text()
let bodydeals = $(this).find('td:nth-child(2)').text()
let newdeal = $(this).find('td:nth-child(3)').text()
let revdeal = $(this).find('td:nth-child(4)').text()
let monthlydealrev = $(this).find('td:nth-child(5)').text()
// Clear /n
if (date.includes(nwline)) {
date = date.toString().replace("\n", ""),
date = date.toString().replace("\n", "")
}
// Clear /n
if (bodydeals.includes(nwline)) {
bodydeals = bodydeals.toString().replace("\n", ""),
bodydeals = bodydeals.toString().replace("\n", ""),
bodydeals = bodydeals.toString().replace("\n", "")
}
// Clear /n
if (newdeal.includes(nwline)) {
newdeal = newdeal.toString().replace("\n", ""),
newdeal = newdeal.toString().replace("\n", ""),
newdeal = newdeal.toString().replace("\n", "")
}
// Clear /n
if (revdeal.includes(nwline)) {
revdeal = revdeal.toString().replace("\n", ""),
revdeal = revdeal.toString().replace("\n", ""),
revdeal = revdeal.toString().replace("\n", "")
}
// Clear /n (lookup jquery table functions)
if (monthlydealrev.includes(nwline)) {
monthlydealrev = monthlydealrev.toString().replace("\n", ""),
monthlydealrev = monthlydealrev.toString().replace("\n", ""),
monthlydealrev = monthlydealrev.toString().replace("\n", "")
}
totaldeals.push({
date,
bodydeals,
newdeal,
revdeal,
monthlydealrev
})
})
callback({
totaldeals
})
//console.log(totaldeals[1].date)
})
.catch(console.error);
}
//console.log(totaldeals)
getip()
我在代码中就结果添加了注释。我看到如果我在axios /中使用console.log(totaldeals [1] .date),那么...如何在该范围之外访问?
