Question

我刚开始服用硒。

我制作了一个简单的python脚本，应该打开一个网址并在那里打印产品的价格。

这是：

from selenium import webdriver
import time
driver = webdriver.PhantomJS(executable_path='/usr/bin/phantomjs')
url = 'http://www.stance.com/shop/product/paint-trap'
print "Driver Made"
driver.get(url)
print "URL got"
price = driver.find_element_by_xpath('//*[@id="h1--title-price"]/span[2]').text
print price
driver.close()

但是，它只是打印：＆＃34; Driver Made＆＃34;并且从不打印＆＃34; URL得到＆＃34;也不是价格。

似乎卡在了driver.get（url）上，但我不知道为什么。

我想知道如何打印价格以及如何阻止driver.get（url）永远运行。

如果我用ctrl C打断它，我得到：

Driver Made
^CTraceback (most recent call last):
  File "test.py", line 6, in <module>
    driver.get(url)
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 213, in get
    self.execute(Command.GET, {'url': url})

    response = self.command_executor.execute(driver_command, params)

    result = func(*args)

    return self.do_open(httplib.HTTPConnection, req)

    response.begin()

    version, status, reason = self._read_status()
  File "/usr/local/lib/python2.7/httplib.py", line 365, in _read_status
    line = self.fp.readline(_MAXLINE + 1)
  File "/usr/local/lib/python2.7/socket.py", line 476, in readline
    data = self._sock.recv(self._rbufsize)
KeyboardInterrupt

工作代码打印 - （在Windows中）。

Driver Made
URL got
$14.00

工作代码如下

from selenium import webdriver
import time
driver = webdriver.PhantomJS(executable_path=r"C:\Users\Desktop\phantomjs.exe")

driver.set_window_size(1120, 550)
url = 'http://www.stance.com/shop/product/paint-trap'
print "Driver Made"
driver.get(url)
print "URL got"
driver.implicitly_wait(5)
price = driver.find_elements_by_xpath("(//*[@id='h1--title-price']/span)[2]")
for i in price:
    print i.text
driver.close()

<强> N.B。确保幻像可执行路径和selenium库在其他组件中是正确的。

硒基本打开一个网址
