这里只是关于你可以用webdriver和幻像做的最简单的打开和关闭:
from selenium import webdriver
crawler = webdriver.PhantomJS()
crawler.set_window_size(1024,768)
crawler.get('https://www.google.com/')
crawler.quit()
在Windows(7)上,每次运行我的代码来测试时,conhost.exe和phantomjs.exe进程的新实例都会开始,永不退出。我在这里做些蠢事吗?我认为当crawler.quit()
做了......

去图。重启时解决了问题。

重新启动不是此问题的解决方案。我在LINUX系统中试验过这个hack。尝试修改service.py
中定义的def stop(self):
"""
Cleans up the process
"""
if self._log:
self._log.close()
self._log = None
#If its dead dont worry
if self.process is None:
return
#Tell the Server to properly die in case
try:
if self.process:
self.process.stdin.close()
#self.process.kill()
self.process.send_signal(signal.SIGTERM)
self.process.wait()
self.process = None
except OSError:
# kill may not be available under windows environment
pass
函数
send_signal
明确添加行import signal
以提供退出phantomjs进程的信号。不要忘记在此文件的开头添加o2 := bson.M{
"$project":bson.M{"_id":1,"title":1,"postdatetime":1,"status":1"answer":bson.M{
"$filter":bson.M{"input":"$answer","as":"ans","cond":bson.M{"$eq":[]string{"$$ans.status","Active",},},},},},}
语句。
