Python下载嵌入页面的PDF [英] Python Download PDF Embedded in a Page

问题描述

我有此链接:

• http://www.equibase.com/premium/chartEmb.cfm?track=ALB&raceDate=06/17/2002&cy=USA&rn=1

我想下载嵌入的PDF.

I want to download the embedded PDF.

我尝试了urllib和request的常规方法，但是它们不起作用.

I have tried the normal methods of urllib and request but they're not working.

import urllib2

url = "http://www.equibase.com/premium/chartEmb.cfm?track=ALB&raceDate=06/17/2002&cy=USA&rn=1"
response = urllib2.urlopen(url)
file = open("document.pdf", 'wb')
file.write(response.read())
file.close()

此外，我也试图找到pdf的原始链接，但它也没有用.

Moreover, I have also tried to find the original link of the pdf but it also did not work.

  将Selenium与特定的ChromeProfile结合使用，您可以使用以下代码下载嵌入式pdf:

  Using Selenium with a specific ChromeProfile you can download embedded pdfs using the following code:

  代码:

  def download_pdf(lnk):
  
      from selenium import webdriver
      from time import sleep
  
      options = webdriver.ChromeOptions()
  
      download_folder = "C:\\"    
  
      profile = {"plugins.plugins_list": [{"enabled": False,
                                           "name": "Chrome PDF Viewer"}],
                 "download.default_directory": download_folder,
                 "download.extensions_to_open": ""}
  
      options.add_experimental_option("prefs", profile)
  
      print("Downloading file from link: {}".format(lnk))
  
      driver = webdriver.Chrome(chrome_options = options)
      driver.get(lnk)
  
      filename = lnk.split("/")[4].split(".cfm")[0]
      print("File: {}".format(filename))
  
      print("Status: Download Complete.")
      print("Folder: {}".format(download_folder))
  
      driver.close()
  

  当我调用此函数时:

  download_pdf("http://www.equibase.com/premium/eqbPDFChartPlus.cfm?RACE=1&BorP=P&TID=ALB&CTRY=USA&DT=06/17/2002&DAY=D&STYLE=EQB")
  

  多数民众赞成在输出:

  >>> Downloading file from link: http://www.equibase.com/premium/eqbPDFChartPlus.cfm?RACE=1&BorP=P&TID=ALB&CTRY=USA&DT=06/17/2002&DAY=D&STYLE=EQB
  >>> File: eqbPDFChartPlus
  >>> Status: Download Complete.
  >>> Folder: C:\
  

  查看特定的个人资料:

  profile = {"plugins.plugins_list": [{"enabled": False,
                                       "name": "Chrome PDF Viewer"}],
             "download.default_directory": download_folder,
             "download.extensions_to_open": ""}
  

  它禁用Chrome PDF Viewer插件(将pdf嵌入网页)，将默认下载文件夹设置为在download_folder变量中定义的文件夹，并设置不允许Chrome自动打开任何扩展程序.

  It disables the Chrome PDF Viewer plugin (that embedds the pdf at the webpage), set the default download folder to the folder defined at download_folder variable and sets that Chrome isn't allowed to open any extensions automatically.

  之后，当您打开所谓的内部链接"时，您的网络驱动程序会自动将.pdf文件下载到download_folder.

  After that, when you open the so called "Internal link" your webdriver will automatically download the .pdf file to the download_folder.
