在Python中使用请求下载多个文件
问题描述:
当前我面临以下问题:
我在列表中有3个下载链接.仅列表中的最后一个文件被完全下载.其他文件的大小为1 KB.
I have 3 download links in a list. Only the last file in the list is downloaded completely. The others have a file size of one kilobyte.
代码:
from requests import get
def download(url, filename):
with open(filename, "wb") as file:
response = get(url, stream=True)
file.write(response.content)
for link in f:
url = link
split_url = url.split("/")
filename = split_url[-1]
filename = filename.replace("\n", "")
download(url,filename)
结果如下:
如何确保所有文件都正确下载?所有链接都是直接下载链接.
How do I make sure that all files are downloaded correctly? All links are direct download links.
提前谢谢!
我发现只有在读取.txt中的链接时才会发生
I discovered it only happens when I read the links from the .txt
如果我这样在python中创建列表:
If I create the list in python like this:
links = ["http://ipv4.download.thinkbroadband.com/20MB.zip",
"http://ipv4.download.thinkbroadband.com/10MB.zip",
"http://ipv4.download.thinkbroadband.com/5MB.zip"]
...问题没有出现.
... the problem doesnt appear.
可复制的示例:
from requests import get
def download(url, filename):
with open(filename, "wb") as file:
response = get(url, stream = True)
file.write(response.content)
f = open('links.txt','r')
for link in f:
url = link
split_url = url.split("/")
filename = split_url[-1]
filename = filename.replace("\n", "")
download(url,filename)
links.txt的内容:
content of links.txt:
http://ipv4.download.thinkbroadband.com/20MB.zip
http://ipv4.download.thinkbroadband.com/10MB.zip
http://ipv4.download.thinkbroadband.com/5MB.zip
答
url = url.replace("\ n",")
url = url.replace("\n", "")
解决了!
