如何使用python通过https下载pdf文件

I am writing a python script, which will save pdf file locally according to the format given in URL. for eg.

我正在编写一个python脚本，它将根据URL中给出的格式在本地保存pdf文件。如。

https://Hostname/saveReport/file_name.pdf   #saves the content in PDF file.

I am opening this URL through python script :

我正在通过python脚本打开这个URL:

 import webbrowser
 webbrowser.open("https://Hostname/saveReport/file_name.pdf")

The url contains lots of images and text. Once this URL is opened i want to save a file in pdf format using python script.

该url包含大量图像和文本。打开这个URL后，我想使用python脚本以pdf格式保存文件。

This is what i have done so far.
Code 1:

这就是我到目前为止所做的。代码1:

import requests
url="https://Hostname/saveReport/file_name.pdf"    #Note: It's https
r = requests.get(url, auth=('usrname', 'password'), verify=False)
file = open("file_name.pdf", 'w')
file.write(r.read())
file.close()

Code 2:

代码2:

 import urllib2
 import ssl
 url="https://Hostname/saveReport/file_name.pdf"
 context = ssl._create_unverified_context()
 response = urllib2.urlopen(url, context=context)  #How should i pass authorization details here?
 html = response.read()

In above code i am getting: urllib2.HTTPError: HTTP Error 401: Unauthorized

在上面的代码中，我得到:urllib2。HTTPError: HTTP错误401:未授权

If i use Code 2, how can i pass authorization details?

如果使用代码2，如何传递授权细节?

I think this will work

我想这行得通

import requests
url="https://Hostname/saveReport/file_name.pdf"    #Note: It's https
r = requests.get(url, auth=('usrname', 'password'), verify=False,stream=True)
r.raw.decode_content = True
with open("file_name.pdf", 'wb') as f:
        shutil.copyfileobj(r.raw, f)

You can try something like :

你可以试试:

import requests
response = requests.get('https://websitewithfile.com/file.pdf',verify=False, auth=('user', 'pass'))
with open('file.pdf','w') as fout:
   fout.write(response.read()):

#3

One way you can do that is:

一种方法是:

import urllib3
urllib3.disable_warnings()
url = r"https://websitewithfile.com/file.pdf"
fileName = r"file.pdf"
with urllib3.PoolManager() as http:
    r = http.request('GET', url)
    with open(fileName, 'wb') as fout:
        fout.write(r.data)
