尝试使用 Python 下载文件时出错

Question

我一直在尝试下载一个链接来自动化股票市场并且我的代码运行但 zip 文件没有被下载。

import urllib
import urllib2
import requests

url ='https://www.nseindia.com/content/historical/EQUITIES/2016/DEC/cm29DEC2016bhav.csv.zip'
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}
print "downloading with urllib"
urllib.urlretrieve(url, "code.zip")

print "downloading with urllib2"
req = urllib2.Request(url, headers=hdr)
f = urllib2.urlopen(req)
data = f.read()
with open("code2.zip", "wb") as code:
    code.write(data)

print "downloading with requests"
r = requests.get(url)
with open("code3.zip", "wb") as code:
    code.write(r.content)

我希望将 zip 文件下载到 C:\Users\User\Downloads 文件夹中，以便我可以自动执行解压缩过程，然后将该 csv 文件保存到硬盘中。任何帮助，将不胜感激。谢谢。

文件正在下载到当前工作目录，可能是C:\Python[Version]。去那里检查。试试这个下载到Downloads文件夹：

import requests

url ='https://www.nseindia.com/content/historical/EQUITIES/2016/DEC/cm29DEC2016bhav.csv.zip'
print "downloading with requests"
r = requests.get(url)
with open("C:\Users\User\Downloads\code3.zip", "w") as code:
    code.write(r.content)
