Question

我正在尝试通过此URL的请求下载此图像，但是idk在第17行出现了某些错误，未定义问题所在。

我尝试添加带有网址的http：//，以使其成为一个清晰的网址。

这是我编写的代码。

from selenium import webdriver
from bs4 import BeautifulSoup
import requests
import os
driver = webdriver.Chrome(executable_path= r'E:/Summer/FirstThings/Web scraping (bucky + pdf)/webscraping/tutorials-master/chromedriver.exe')
url = 'https://www.nba.com/players/jaylen/adams/1629121'
driver.get(url)
#print(driver.page_source)

soup = BeautifulSoup(driver.page_source , 'lxml')
div = soup.find('section' , class_='nba-player-header__item nba-player-header__headshot')
img = div.find('img')
print("")
m=('http://'+ img['src'])

f = open('jaylen_adams.jpg','w')
f.write(requests.get(m).content)
f.close()

driver.__exit__()

Answer 1

发现的错误：

首先，您需要在尝试访问无效的http:////ak-static.cms.nba.com/wp-content/uploads/headshots/nba/latest/260x190/1629121.png时修复该URL。因此，将行更改为：

m=('http:'+ img['src'])

第二，您需要写为字节。因此更改为：

f = open('C:/jaylen_adams.jpg','wb')

代码：

from selenium import webdriver
from bs4 import BeautifulSoup
import requests
import os
driver = webdriver.Chrome('C:/chromedriver_win32/chromedriver.exe')
url = 'https://www.nba.com/players/jaylen/adams/1629121'
driver.get(url)
#print(driver.page_source)

soup = BeautifulSoup(driver.page_source , 'lxml')
div = soup.find('section' , class_='nba-player-header__item nba-player-header__headshot')
img = div.find('img')
print("")
m=('http:'+ img['src'])  # <----- edit made here

f = open('C:/jaylen_adams.jpg','wb')   # <---- edit made here
f.write(requests.get(m).content)
f.close()

driver.__exit__()

ALSO：：无需使用硒，因为如果您要处理多个页面，这可能会减慢该过程。您可以只使用请求来简化它，如果将文件放在.close()语句中，则不需要使用with文件，因为文件完成后会自动关闭：

短代码：

from bs4 import BeautifulSoup
import requests

url = 'https://www.nba.com/players/jaylen/adams/1629121'
response = requests.get(url)

soup = BeautifulSoup(response.text , 'lxml')
div = soup.find('section' , class_='nba-player-header__item nba-player-header__headshot')
img = div.find('img')
print("")
m=('http:'+ img['src'])

with open('C:/jaylen_adams.jpg','wb') as f:
    f.write(requests.get(m).content)

我正在尝试使用python的请求模块从网络下载并保存图像
