[已解决]百度翻译

TCY

看别人发了一个百度翻译的代码：

from selenium import webdriver
import time

options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
browser = webdriver.Chrome(chrome_options = options)
browser.get('https://fanyi.baidu.com/#auto/zh/')
input_area = browser.find_element_by_css_selector('#baidu_translate_input')

content = input('请输入你需要翻译的内容：')
input_area.send_keys(content)
time.sleep(2)
output_area = browser.find_element_by_css_selector('#main-outer > div > div > \
div.translate-wrap > div.translateio > div.translate-main.clearfix > \
div.trans-right > div > div > div.output-bd > \
p.ordinary-output.target-output.clearfix > span')
print('翻译结果：',output_area.text)
browser.close()

执行结果：

Traceback (most recent call last):
  File "D:\Python\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
    stdin=PIPE)
  File "D:\Python\lib\subprocess.py", line 709, in __init__

During handling of the above exception, another exception occurred:

https://fishc.com.cn/thread-121621-1-1.html你按这个帖子的镜像去下载chromedriver，下载完放到scripts文件夹下

零度非安全

要下对应浏览器的版本的驱动，并把它放在 Python 安装目录里，selenium 才会正常工作

下载谷歌浏览器，下载对应的chromedriver,那不是我的代码吗

确实，我最近在搞百度翻译，看到你这代码直接拿来用了

对了，对于谷歌内核的浏览器，代码有效吗？

又怎么了（谷歌驱动版本：2.29，2345浏览器谷歌内核：56.0.2924.90）

塔利班

你没下对版本

塔利班

下2。39的

TCY

还是不行……因此换IE了

塔利班

你下了那个，然后360软件管家按个谷歌浏览器就行了

代码改了一下：

from selenium import webdriver
import time

content = input('请输入你需要翻译的内容：')
options = webdriver.IeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
browser = webdriver.Ie(options = options)
browser.get('https://fanyi.baidu.com')
input_area = browser.find_element_by_css_selector('#baidu_translate_input')

input_area.send_keys(content)
time.sleep(2)
output_area = browser.find_element_by_css_selector('#main-outer > div > div > \
div.translate-wrap > div.translateio > div.translate-main.clearfix > \
div.trans-right > div > div > div.output-bd > \
p.ordinary-output.target-output.clearfix > span')
print('翻译结果：',output_area.text)
browser.close()

结果：

请输入你需要翻译的内容：hello
Traceback (most recent call last):
  File "C:\Users\admin\Desktop\hello.py", line 10, in <module>
    input_area = browser.find_element_by_css_selector('#baidu_translate_input')
  File "D:\Python\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 598, in find_element_by_css_selector
    return self.find_element(by=By.CSS_SELECTOR, value=css_selector)
  File "D:\Python\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 978, in find_element
    'value': value})['value']
  File "D:\Python\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "D:\Python\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: Unable to find element with css selector == #baidu_translate_input

IE能正常启动，这是什么情况

你这么好像@不出来我，我也没有提醒，当网页没有加载完毕（你的网速慢的时候可能控件没有加载出来），
需要until那个什么函数，这里用sleep只是人为控制时间然后读取，可能你的网速比较慢，未实现控件加载

塔利班

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))
    )
finally:
    driver.quit()

这个是selenium 官方的waits文档
参照这个你把ID换成CSS选择器，对应变量名设置下，我没有按IE得驱动，你按文档改下就行

TCY

IE加载慢，超时了……代码仍在改进中
