我有一个Python脚本,该脚本使用硒从website抓取URL并将其存储在列表中,然后我想使用wget模块下载它们。
这是代码的相关部分,其中脚本完成了从网站获得的部分URL:
new_links = []
for link in list_of_links: # trim links
current_strings = link.split("/consultas/coleccion/window.open('")
current_strings[1] = current_strings[1].split("');return")[0]
new_link = current_strings[0] + current_strings[1]
new_links.append(new_link)
for new_link in new_links:
wget.download(new_link)
脚本目前不执行任何操作。它从不下载任何PDF,也不会发出错误消息。
在第二个for循环中我做了什么错事?
编辑:
关于new_links
是否为空的问题。不是。
print(*new_links, sep = '\n')
为我提供了以下链接(这里只是其中的四个):

编辑2:
部分URL看起来像/consultas/util/pdf.php?type=rdd&rdd=vPjrUnz0wbA%3D
然后将“基本URL”添加到http://digesto.asamblea.gob.ni
之前。
这是代码的相关部分,位于上面的代码之前,它收集部分URL:
list_of_links = [] # will hold the scraped links
tld = 'http://digesto.asamblea.gob.ni'
current_url = driver.current_url # for any links not starting with /
table_id = driver.find_element(By.ID, 'tableDocCollection')
rows = table_id.find_elements_by_css_selector("tbody tr") # get all table rows
for row in rows:
row.find_element_by_css_selector('button').click()
link = row.find_element_by_css_selector('li a[onclick*=pdf]').get_attribute("onclick") # get partial link
if link.startswith('/'):
list_of_links.append(tld + link) # add base to partial link
else:
list_of_links.append(current_url + link)
row.find_element_by_css_selector('button').click()
答案 0 :(得分:1)
您的循环正在运行。您可以尝试将您的wget版本升级到3.2并检查
new_links = ['http://digesto.asamblea.gob.ni/consultas/util/pdf.php?type=rdd&rdd=vPjrUnz0wbA%3D',
'http://digesto.asamblea.gob.ni/consultas/util/pdf.php?type=rdd&rdd=dsyx6l1Fbig%3D',
'http://digesto.asamblea.gob.ni/consultas/util/pdf.php?type=rdd&rdd=Cb64W7EHlD8%3D',
'http://digesto.asamblea.gob.ni/consultas/util/pdf.php?type=rdd&rdd=A4TKEG9x4F8%3D']
for new_link in new_links:
wget.download(new_link)
Output: four files got downloaded in the name of pdf.php, pdf(1).php .,etc
