另一种方法是调用外部进程，如curl.exe。Curl在默认情况下显示进度条、平均下载速度、剩余时间等，所有这些都整齐地格式化在一个表格中。 将curl.exe放在与脚本相同的目录中

from subprocess import call
url = ""
call(["curl", {url}, '--output', "song.mp3"])

注意:不能使用curl指定输出路径，所以使用os。重命名之后

我写了下面的代码，它可以在普通的Python 2或Python 3中工作。

import sys
try:
    import urllib.request
    python3 = True
except ImportError:
    import urllib2
    python3 = False


def progress_callback_simple(downloaded,total):
    sys.stdout.write(
        "\r" +
        (len(str(total))-len(str(downloaded)))*" " + str(downloaded) + "/%d"%total +
        " [%3.2f%%]"%(100.0*float(downloaded)/float(total))
    )
    sys.stdout.flush()

def download(srcurl, dstfilepath, progress_callback=None, block_size=8192):
    def _download_helper(response, out_file, file_size):
        if progress_callback!=None: progress_callback(0,file_size)
        if block_size == None:
            buffer = response.read()
            out_file.write(buffer)

            if progress_callback!=None: progress_callback(file_size,file_size)
        else:
            file_size_dl = 0
            while True:
                buffer = response.read(block_size)
                if not buffer: break

                file_size_dl += len(buffer)
                out_file.write(buffer)

                if progress_callback!=None: progress_callback(file_size_dl,file_size)
    with open(dstfilepath,"wb") as out_file:
        if python3:
            with urllib.request.urlopen(srcurl) as response:
                file_size = int(response.getheader("Content-Length"))
                _download_helper(response,out_file,file_size)
        else:
            response = urllib2.urlopen(srcurl)
            meta = response.info()
            file_size = int(meta.getheaders("Content-Length")[0])
            _download_helper(response,out_file,file_size)

import traceback
try:
    download(
        "https://geometrian.com/data/programming/projects/glLib/glLib%20Reloaded%200.5.9/0.5.9.zip",
        "output.zip",
        progress_callback_simple
    )
except:
    traceback.print_exc()
    input()

注:

支持“进度条”回调。 从我的网站上下载一个4 MB的测试包。zip。

这可能有点晚了，但我看到了pabloG的代码，忍不住添加了一个os.system('cls')，使它看起来很棒!看看吧:

    import urllib2,os

    url = "http://download.thinkbroadband.com/10MB.zip"

    file_name = url.split('/')[-1]
    u = urllib2.urlopen(url)
    f = open(file_name, 'wb')
    meta = u.info()
    file_size = int(meta.getheaders("Content-Length")[0])
    print "Downloading: %s Bytes: %s" % (file_name, file_size)
    os.system('cls')
    file_size_dl = 0
    block_sz = 8192
    while True:
        buffer = u.read(block_sz)
        if not buffer:
            break

        file_size_dl += len(buffer)
        f.write(buffer)
        status = r"%10d  [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
        status = status + chr(8)*(len(status)+1)
        print status,

    f.close()

如果在Windows以外的环境中运行，你必须使用'cls'以外的东西。在MAC OS X和Linux中，它应该是“清晰的”。

另一种可能是使用内置的http.client:

from http import HTTPStatus, client
from shutil import copyfileobj

# using https
connection = client.HTTPSConnection("www.example.com")
with connection.request("GET", "/noise.mp3") as response:
    if response.status == HTTPStatus.OK:
        copyfileobj(response, open("noise.mp3")
    else:
        raise Exception("request needs work")

HTTPConnection对象被认为是“低级的”，因为它只执行一次所需的请求，并假设开发人员将对它或脚本进行子类化，以处理HTTP的细微差别。诸如请求之类的库倾向于处理更特殊的情况，例如自动跟随重定向等等。

Python 3

urllib.request.urlopen 进口urllib.request Response = urllib.request.urlopen('http://www.example.com/') HTML = response.read() urllib.request.urlretrieve 进口urllib.request urllib.request.urlretrieve (' http://www.example.com/songs/mp3.mp3 ', ' mp3.mp3 ') 注意:根据文档，urllib.request.urlretrieve是一个“遗留接口”，并且“在未来可能会被弃用”(感谢gerrit)

Python 2

urllib2。urlopen(谢谢科里) 进口urllib2 Response = urllib2.urlopen('http://www.example.com/') HTML = response.read() urllib。urlretrieve(感谢PabloG) 进口urllib urllib.urlretrieve (' http://www.example.com/songs/mp3.mp3 ', ' mp3.mp3 ')

基于urllib3的新Api实现

>>> import urllib3
>>> http = urllib3.PoolManager()
>>> r = http.request('GET', 'your_url_goes_here')
>>> r.status
   200
>>> r.data
   *****Response Data****
