帮我找一下这段代码的错误，并改正import urllib.parse import urllib.request def create_request(page): base_url = 'https://movie.douban.com/j/chart/top_list?type=5&interval_id=100%3A90&action=&' data = { 'start':(page - 1) * 20, 'limit':20 } data = urllib.parse.urlencode(data) url = base_url + data # print(url) headers = { # 'User - Agent': 'Mozilla / 5.0(Windows NT 10.0;WOW64) AppleWebKit / 537.36(KHTML, likeGecko) Chrome / 108.0.5359.95Safari / 537.36' 'User - Agent': 'Mozilla / 5.0(Windows NT 10.0;WOW64) AppleWebKit / 537.36(KHTML, likeGecko) Chrome / 108.0.5359.95Safari / 537.36' } request = urllib.request.Request(url=url,headers=headers) return request def get_content(request): response = urllib.request.urlopen(request) content = response.read().decode('utf-8') return content def down_load(page,content): with open ('douban_' + str(page) + '.json','w',encoding='utf-8') as fp: fp.write(content) if __name__ == '__main__': start_page = int (input('请输入开始的页码')) end_page = int (input('请输入结束的页码')) for page in range(start_page,end_page+1): # 每一页都有请求对象的定制 request = create_request(page) content = get_content(request) down_load(page,content)

该代码存在两个错误：

1. headers中的键名有空格，需要去掉空格。

2. down_load函数名错误，应为download。

改正后的代码如下：

import urllib.parse
import urllib.request


def create_request(page):
    base_url = 'https://movie.douban.com/j/chart/top_list?type=5&interval_id=100%3A90&action=&'
    data = {
        'start': (page - 1) * 20,
        'limit': 20
    }
    data = urllib.parse.urlencode(data)
    url = base_url + data
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.5359.95 Safari/537.36'
    }
    request = urllib.request.Request(url=url, headers=headers)
    return request


def get_content(request):
    response = urllib.request.urlopen(request)
    content = response.read().decode('utf-8')
    return content


def download(page, content):
    with open('douban_' + str(page) + '.json', 'w', encoding='utf-8') as fp:
        fp.write(content)


if __name__ == '__main__':
    start_page = int(input('请输入开始的页码'))
    end_page = int(input('请输入结束的页码'))
    for page in range(start_page, end_page + 1):
        request = create_request(page)
        content = get_content(request)
        download(page, content)
