我正在使用Node.js和Express开发一个应用程序。我的一个路由文件中包含以下内容：
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
SITE_URL = 'https://www.facebook.com/pg/mnagaazdorp/posts/'
POSTS_XPATH = "//*[contains(@class, '_4-u2') and contains(@class, '_4-u8')]"
POST_TEXT_CLASS = "userContent"
TIMEOUT = 1
CHROME_DRIVER_PATH = "C:\\Users\\tonda\\Documents\\chromedriver.exe"
browser = webdriver.Chrome(executable_path=CHROME_DRIVER_PATH)
browser.get(SITE_URL)
wait = WebDriverWait(browser, TIMEOUT)
posts = browser.find_elements_by_xpath(POSTS_XPATH)
for post in posts:
post_text_element = post.find_element_by_class_name(POST_TEXT_CLASS)
print(post_text_element.text)
browser.quit()
该router.get('/', (req, res) => {
Manufacturer.find({}, (err, manufacturers) => {
if(err) {
console.log(err)
req.flash('error', 'No manufacturers were found')
res.redirect('/')
}
let allAircrafts = {"manufacturers": {}}
for(let key in manufacturers) {
let currentManufacturerAircrafts = []
let manufacturerName = manufacturers[key].name
Aircraft.find({manufacturer_name: manufacturerName}, (err, aircrafts) => {
if(err) {
console.log(err)
req.flash('error', 'No aircrafts were found')
res.redirect('/')
}
for(let akey in aircrafts) {
currentManufacturerAircrafts.push(aircrafts[akey])
}
// let manufacturerObj = {name: manufacturerName, aircrafts: currentManufacturerAircrafts}
allAircrafts["manufacturers"][manufacturerName] = currentManufacturerAircrafts
// console.log(allAircrafts) #1
})
}
// console.log(allAircrafts) #2
res.render('aircrafts', { expressFlash: req.flash(), sessionFlash: res.locals.sessionFlash, allAircrafts})
})
})
对象应该存储所有制造商的所有飞机，当我在下面的＃1中allAircrafts它确实起作用时，我得到了期望值。
当我在＃2中console.log时，我只会得到这个：
console.log我不知道为什么要向我显示此内容，但是我怀疑它没有正确保存它。
