下面是我的代码来刮一个网站使用美丽的汤..代码在Windows上运行良好,但在Ubuntu的问题。在Ubuntu中,代码有时会运行,有时会出错。有时代码运行,有时它会给出错误
的误差小于:

下面是我的代码:
import requests

workbook = xlrd.open_workbook(file_location)

for r in range(sheet.nrows):
products.append(sheet.cell_value(r,0))
book = xlwt.Workbook(encoding= "utf-8", style_compression = 0)
sheet = book.add_sheet("Sheet11", cell_overwrite_ok=True)
for index, url in enumerate(products):
new_url = "http://www." + url
source = requests.get(new_url)
data = source.content
soup = BeautifulSoup(data, "lxml")
sheet.write(index, 0, url)

sheet.write(index, 1, Product_Name)

book.save("Craftsvilla Output.xls")

注意:对于一些人的代码将运行,但尝试一段时间..相同的代码会给出错误..不知道为什么?? ..和相同的代码将永远不会给任何错误在Windows上。
我觉得你在较短的时间内发送来自同一IP地址的请求数量过多,因此,服务器可能会拒绝您的连接。 –
但为什么相同的代码不会给窗口上的错误。 – Nitin
在'new_url'之后加上'print(new_url)',我认为你读了xlsx文件并得到了不完整的数据。 –
