带有 HTTP 错误 400：错误请求的 Python 脚本

Question

This code is to get some images from the URL stored in the excel file. The code is also to save them but when I ran the code, I got this error "HTTPError: HTTP Error 400: Bad Request". What can I do to solve the problem?

import pandas as pd
import urllib.request

def url_to_jpg(i, url, file_Path):

    filename = 'image_{}.jpg'.format(i)
    full_path = '{}{}'.format(file_Path, filename)
    urllib.request.urlretrieve(url, full_path)

    print('{} saved.'.format(filename))
    return None

File_Name = 'Cooler_URL_2.xlsx'
File_Path = 'images/'

#reading the file as pandas dataframe
urls = pd.read_excel(File_Name)

#save file as directory
for i, url in enumerate(url_values):
    url_to_jpg(i, url[0], File_Path)

Answer 1

As mentioned, the most common cause of a 400 Bad Request Error is simply inputting an incorrect URL. Domain names (eg abc.com) are case-insensitive, meaning that this mixed case link to ABC.COM works just as well as the normal, lowercase version of abc.com.

Answer 2

下面这行for i, url in enumerate(url_values): url_to_jpg(i, url[0], File_Path)被替换为for i, url in enumerate(url_values): url_to_jpg(i, url, File_Path)
