Python下载嵌入页面的PDF

Question

我有这个链接：

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

我想下载嵌入式PDF。

我尝试了urllib和request的常规方法，但是它们不起作用。

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()

而且，我也试图找到pdf的原始链接，但它也没有用。

内部链接：

Answer 1

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：

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")

那就是输出：

>>> 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:\

---

看一下特定的配置文件：

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

它将禁用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。

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download_folder到download_folder 。
