Python 从 kickstarter 抓取数据的代码在一些迭代后不起作用

Question

我尝试从 kickstarter 抓取数据，代码可以正常工作，但在第 15 页出现以下错误（由于网页是动态的，您可能会在不同的页面出现错误）：

Traceback (most recent call last): File "C:\Users\lenovo\kick.py", line 30, in csvwriter.writerow(row) File "C:\Users\lenovo\AppData\Local\Programs\Python\Python37\lib\encodings\cp1252.py", line 19, in encode return codecs.charmap_encode(input,self.errors,encoding_table)[0] UnicodeEncodeError: 'charmap' codec can't encode character '\uff5c' in position 27: character maps to

可能是什么问题？有什么建议吗？

from urllib.request import urlopen
from bs4 import BeautifulSoup
import json
import csv
KICKSTARTER_SEARCH_URL = "https://www.kickstarter.com/discover/advanced?category_id=16&sort=newest&seed=2502593&page={}"
DATA_FILE = "kickstarter.csv"
csvfile = open(DATA_FILE, 'w')
csvwriter = csv.writer(csvfile, delimiter=',')
page_start = 0
while True:
    url = KICKSTARTER_SEARCH_URL.format(page_start)
    print(url)
    response = urlopen(url)
    html = response.read()
    soup = BeautifulSoup(html, 'html.parser')
    project_details_divs = soup.findAll('div', {"class":"js-react-proj-card"})

    if len(project_details_divs) == 0:
        break;

    for div in project_details_divs:
        project = json.loads(div['data-project'])
        row = [project["id"],project["name"],project["goal"],project["pledged"]]
        csvwriter.writerow(row)

    page_start +=1

csvfile.close()

Answer 1

将参数 encoding 添加到您的文件打开器。我是说，改变

csvfile = open(DATA_FILE, 'w')

进入

csvfile = open(DATA_FILE, 'w', encoding='utf-8')
