尝试使用 Python 从 URL 下载文件时出现 HTTP 403 错误

Question

我正在尝试从 URL -> https://www.microsoft.com/en-us/download/confirmation.aspx?id=56519

下载文件

我可以通过浏览器访问 URL 来手动下载文件，文件会自动保存到本地计算机的“下载”文件夹中。 (文件格式为JSON)

但是，我需要使用 Python 脚本来实现。我尝试使用 urllib.request & wget，但在这两种情况下我都不断收到错误 -

    urllib.request.urlretrieve(url, path)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 247, in urlretrieve
    with contextlib.closing(urlopen(url, data)) as fp:
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 531, in open
    response = meth(req, response)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 641, in http_response
    'http', request, response, code, msg, hdrs)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 569, in error
    return self._call_chain(*args)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 503, in _call_chain
    result = func(*args)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 649, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

Answer 1

Python 3

import urllib.request, json 
with urllib.request.urlopen("https://download.microsoft.com/download/7/1/D/71D86715-5596-4529-9B13-DA13A5DE5B63/ServiceTags_Public_20210329.json") as url:
    data = json.loads(url.read().decode())
    print(data)

Answer 2

Is there a workaround to this? Dealing with dynamic changes ?

您可以尝试以下脚本来下载 url 并下载 json 文件：

import requests
import re
import urllib.request

rq= requests.get("https://www.microsoft.com/en-us/download/confirmation.aspx?id=56519")
 
t = re.search("https://download.microsoft.com/download/.*?\.json", rq.text )
 


a= t.group()

print(a)

path = r"$(Build.sourcesdirectory)\agent.json"
urllib.request.urlretrieve(a, path)

结果：
