我有一个简单的收件箱页面,可打开用户消息。问题是,当用户在收件箱页面上单击收件箱中的邮件时,没有任何反应。 我知道为什么会出现这种情况,但对于推入却是如此,对于替换来说,这似乎是一个错误。

正尝试:

#import packages
import numpy as np
import pandas as pd
from bs4 import BeautifulSoup

#start of code
mainurl = "https://aviation-safety.net/database/"
def getAndParseURL(mainurl):
   result = requests.get(mainurl)
   soup = BeautifulSoup(result.content, 'html.parser')
   datatable = soup.find('a', href = True)


#try clause to go through the content and grab the URLs
try:
   for row in datatable:
      cols = row.find_all("|")
      if len(cols) > 1:
         links.append(x, cols = cols)
         except: pass


#place links into numpy array
links_array = np.asarray(links)
len(links_array)


#check if links are in dataframe
df = pd.DataFrame(links_array)

df.columns = ['url']
df.head(10)
