Question

enter image description here我正在使用python 2.7 Flask来开发Web应用程序。我正在尝试从特定URL下载文本文件并保存在应用程序中的静态文件夹中。这是我的代码：

from urllib2 import urlopen

uurl = 'http://textfiles.com/100/ad.txt'


def download(t_url):
    response = urlopen(t_url)
    data = response.read()
    txt_str = str(data)
    lines = txt_str.split("\\n")
    des_url = 'static/forcast.txt'
    fx = open(des_url,"w")
    for line in lines:
        fx.write(line+ "\n")
    fx.close()

download(uurl)

现在我运行此操作并获得以下错误：

Traceback (most recent call last):
  File "/Users/sanam/PycharmProjects/ff/ff.py", line 17, in <module>
    download(uurl)
  File "/Users/sanam/PycharmProjects/ff/ff.py", line 12, in download
    fx = open(des_url,"w")
IOError: [Errno 2] No such file or directory: '/static/forcast.txt'

Answer 1

您的代码没有任何问题，因为它将文件下载到您的python脚本的同一目录中。所以指定文件夹的位置。

from urllib2 import urlopen

uurl = 'http://textfiles.com/100/ad.txt'

def download(t_url):
    response = urlopen(t_url)
    data = response.read()
    txt_str = str(data)
    lines = txt_str.split("\\n")
    des_url = 'folder/forcast.csv'
    fx = open(des_url,"w")
    for line in lines:
        fx.write(line+ "\n")
    fx.close()

download(uurl)

Answer 2

from urllib2 import urlopen

uurl = 'http://textfiles.com/100/ad.txt'

def download(t_url):
    response = urlopen(t_url)
    data = response.read()
    txt_str = str(data)
    lines = txt_str.split("\\n")
    des_url = 'folder/add.txt'
    with open(des_url,"w"):
        for line in lines:
            fx.write(line+ "\n")


download(uurl)
