Selenium 花费太多时间来下载文件

Question

I am using this part of my code to download a some files which I download from clicking a link with a partial text specified, but even with my driver.implicitly_wait(5) , the driver is taking more then 2 minutes to check and download available files.

What's the best pythonic way to do the same as code below?

IMPORTANT, sometimes only one or two of the 4 files are available to download.

driver.find_element_by_xpath('//*[@id="menu"]/li[2]/a').click()
driver.find_element_by_xpath('//*[@id="linkbtconsultar"]/a[1]/span').click()

try:
    driver.find_element_by_partial_link_text('ASD!').click()
except NoSuchElementException:
    return
try:
     driver.find_element_by_partial_link_text('QWE#').click()
except NoSuchElementException:
     return
try:
    driver.find_element_by_partial_link_text('RTY%').click()
except NoSuchElementException:
    return
try:
    driver.find_element_by_partial_link_text('ASD%').click()
except NoSuchElementException:
    return

Answer 1

I would combine the 4 locators into one, return a collection of elements, and then loop through the collection clicking on each one.

Something like this:

driver.find_element_by_xpath('//*[@id="menu"]/li[2]/a').click()
driver.find_element_by_xpath('//*[@id="linkbtconsultar"]/a[1]/span').click()
docs = driver.find_elements_by_xpath('//a[contains(.,'ASD!')] | //a[contains(.,'QWE#')] | //a[contains(.,'RTY%')] | //a[contains(.,'ASD%')]')
for doc in docs:
    doc.click()
    # you probably will need a brief wait here to give the browser time to process each click

This code will try to get all the desired docs and only return ones that exist... but it should be immediate.

You might also consider not using Selenium to download the files and importing the requests module to do so. You could then use something like map to download all files at once.

try:
    files = driver.find_elements_by_partial_link_text('file or extension')[:4]
except NoSuchElementException:
    return
for file in files:
    file.click()
