PhantomJS返回空网页(python、Selenium)
PhantomJS返回空网页(python、Selenium)
提问于 2015-04-06 07:54:32
尝试屏幕抓取网站，而不必在python脚本中启动实际的浏览器实例(使用Selenium)。我可以用Chrome或火狐浏览器来做这件事--我已经试过了，而且还行得通--但我想用PhantomJS，这样它就没什么用了。
代码如下所示：
import sys
import traceback
import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = (
"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/53 "
"(KHTML, like Gecko) Chrome/15.0.87"
)
try:
# Choose our browser
browser = webdriver.PhantomJS(desired_capabilities=dcap)
#browser = webdriver.PhantomJS()
#browser = webdriver.Firefox()
#browser = webdriver.Chrome(executable_path="/usr/local/bin/chromedriver")
# Go to the login page
browser.get("https://www.whatever.com")
# For debug, see what we got back
html_source = browser.page_source
with open('out.html', 'w') as f:
f.write(html_source)
# PROCESS THE PAGE (code removed)
except Exception, e:
browser.save_screenshot('screenshot.png')
traceback.print_exc(file=sys.stdout)
finally:
browser.close()输出结果仅仅是：
<html><head></head><body></body></html>但当我使用Chrome或Firefox选项时，它工作得很好。我想也许网站会根据用户代理返回垃圾信息，所以我试着假装了一下。没什么区别。
我遗漏了什么？
更新:我将尝试保持以下代码片段的更新，直到它工作为止。下面是我目前正在尝试的。

#browser = webdriver.Chrome(executable_path="/usr/local/bin/chromedriver")
# Go to the login page
print "getting web page..."
browser.get("https://www.website.com")
# Need to wait for the page to load
timeout = 10
print "waiting %s seconds..." % timeout
wait = WebDriverWait(browser, timeout)
element = wait.until(EC.element_to_be_clickable((By.ID,'the_id')))
print "done waiting. Response:"
