我有这个链接：

我想下载嵌入的PDF。在

我尝试过urllib和request的常规方法，但它们都不起作用。在

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，我也曾试图找到pdf的原始链接，但也没用。在

Answer 1

将Selenium与特定的ChromeProfile一起使用，您可以使用以下代码下载嵌入式PDF：

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()

当我调用这个函数时：

^{pr2}$

这就是输出：

>>> 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:\

查看具体的个人资料：

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（在网页中嵌入pdf），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Chrome不允许自动打开任何扩展。在

之后，当您打开所谓的“内部链接”时，您的Web驱动程序将自动将.pdf文件下载到download_folder。在
