如何禁用或更改ghostdriver.log的路径? [英] How to disable or change the path of ghostdriver.log?

问题描述

问题是直截了当的，但某些情况下可能会有所帮助.

我正在尝试使用selenium和phantomjs作为下载器时部署scrapy.但是问题在于，它一直说要在部署时拒绝权限.因此，我想更改ghostdriver.log的路径或仅将其禁用.看着phantomjs -h和ghostdriver github页面，我找不到答案，我的朋友google也让我失望了.

解决方案

在使用PhantomJS驱动程序时，请添加以下参数:

driver = webdriver.PhantomJS(service_log_path='/var/log/phantomjs/ghostdriver.log')

相关的代码，虽然可以选择关闭日志记录，但似乎还不支持:

selenium/webdriver/phantomjs/service.py

class Service(object):
    """
    Object that manages the starting and stopping of PhantomJS / Ghostdriver
    """

    def __init__(self, executable_path, port=0, service_args=None, log_path=None):
        """
        Creates a new instance of the Service

        :Args:
         - executable_path : Path to PhantomJS binary
         - port : Port the service is running on
         - service_args : A List of other command line options to pass to PhantomJS
         - log_path: Path for PhantomJS service to log to
        """

        self.port = port
        self.path = executable_path
        self.service_args= service_args
        if self.port == 0:
            self.port = utils.free_port()
        if self.service_args is None:
            self.service_args = []
        self.service_args.insert(0, self.path)
        self.service_args.append("--webdriver=%d" % self.port)
        if not log_path:
            log_path = "ghostdriver.log"
        self._log = open(log_path, 'w')

Question is straightfoward, but some context may help.

I'm trying to deploy scrapy while using selenium and phantomjs as downloader. But the problem is that it keeps on saying permission denied when trying to deploy. So I want to change the path of ghostdriver.log or just disable it. Looking at phantomjs -h and ghostdriver github page I couldn't find the answer, my friend google let me down also.

解决方案

When using the PhantomJS driver add the following parameter:

driver = webdriver.PhantomJS(service_log_path='/var/log/phantomjs/ghostdriver.log')

Related code, would be nice to have an option to turn off logging though, seems thats not supported:

selenium/webdriver/phantomjs/service.py

class Service(object):
    """
    Object that manages the starting and stopping of PhantomJS / Ghostdriver
    """

    def __init__(self, executable_path, port=0, service_args=None, log_path=None):
        """
        Creates a new instance of the Service

        :Args:
         - executable_path : Path to PhantomJS binary
         - port : Port the service is running on
         - service_args : A List of other command line options to pass to PhantomJS
         - log_path: Path for PhantomJS service to log to
        """

        self.port = port
        self.path = executable_path
        self.service_args= service_args
        if self.port == 0:
            self.port = utils.free_port()
        if self.service_args is None:
            self.service_args = []
        self.service_args.insert(0, self.path)
        self.service_args.append("--webdriver=%d" % self.port)
        if not log_path:
            log_path = "ghostdriver.log"
        self._log = open(log_path, 'w')
