我想下载嵌入式PDF。

我尝试了urllib和request的普通方法，但它们都不起作用。

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()

null

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pdfs：

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：

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")

>>> File: eqbPDFChartPlus
>>> Status: Download Complete.
>>> Folder: C:\

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