python+selenium下载文件——firefox

朱雀 2023-10-02 08:53 19阅读 0赞

修改Firefox的相关配置。

1、profile.set\_preference('browser.download.folderList',2)

设置成0代表桌面，1代表下载到浏览器默认下载路径；2代表保存到自定义目录.设置为2的时候，设置自定义路径的就要去掉。

2、profile.set\_preference('browser.download.dir','F:\\\\Users')

保存到指定目录F盘Users文件夹。可以任意文件夹，但是记得分隔符是两个反斜杠

3、profile.set\_preference('browser.download.manager.showWhenStarting',False)

不管是True还是False，都不显示开始，直接开始下载

4、profile.set\_preference('browser.helperApps.neverAsk.saveToDisk','**application/octet-stream ,application/zip,application/kswps,application/pdf**')

不询问下载路径；后面的参数为要下载页面的Content-type的值

Content-type请参考网页：http://www.w3school.com.cn/media/media\_mimeref.asp

from selenium import webdriver
    import time
    
    fp = webdriver.FirefoxProfile()
    fp.set_preference('browser.download.manager.showWhenStarting',False)
    fp.set_preference('browser.download.folderList',2)                        #设置Firefox的默认下载文件夹。0是桌面；1是“我的下载”；2是自定义。
    fp.set_preference('browser.download.dir','C:\\Users\\del\\Desktop\\1')    #设置自定义路径时，定义的路径
    fp.set_preference('browser.helperApps.neverAsk.saveToDisk','application/zip')     #不询问下载路径；后面的参数为要下载页面的文件类型的值。
    
    time.sleep(10)
    
    driver = webdriver.Firefox(firefox_profile=fp)
    driver.implicitly_wait(20)
    driver.get("http://sahitest.com/demo/saveAs.htm")
    
    driver.find_element_by_link_text('testsaveas.zip').click()
    
    
    time.sleep(10)
    driver.quit()
