问题描述

我正在使用 selenium 和 chrome webdriver 从网站上抓取 pdf.我使用以下内容，从列表中拉出 site:

I'm in the process of scraping pdfs from a website using selenium and chrome webdriver. I use the following, pulling the site from a list:

driver.get(site) source = driver.page_source ... ... driver.quit()

但我不断收到以下错误，我的 site 列表中有大约 6,000 次观察:

But I keep getting the following error, about 6,000 observations down my site list:

Traceback (most recent call last): File "<stdin>", line 127, in <module> File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 323, in get self.execute(Command.GET, {'url': url}) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 311, in execute self.error_handler.check_response(response) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 237, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.TimeoutException: Message: timeout (Session info: chrome=63.0.3239.84) (Driver info: chromedriver=2.33.506092 (733a02544d189eeb751fe0d7ddca79a0ee28cce4),platform=Linux 4.10.0-40-generic x86_64)

我尝试过以更短的时间间隔刷新源页面(每 200 次搜索，但我应该缩短吗?).

I've tried refreshing the source page at shorter intervals (every 200 searches, but should I go shorter?).

如何延长 selenium 的 120 秒超时限制?

How do I extend selenium's 120sec timeout limit?

推荐答案

这个错误信息...

Traceback (most recent call last): File "<stdin>", line 127, in <module> File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 323, in get self.execute(Command.GET, {'url': url}) . selenium.common.exceptions.TimeoutException: Message: timeout (Session info: chrome=63.0.3239.84) (Driver info: chromedriver=2.33.506092 (733a02544d189eeb751fe0d7ddca79a0ee28cce4),platform=Linux 4.10.0-40-generic x86_64)

...表示 webdriver 实例无法与 site url 建立连接并发生 timeout.

...implies that the webdriver instance cannot establish a connection with the site url and timeout occurs.

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

Your main issue is the version compatibility between the binaries you are using as follows :

您正在使用 ChromeDriver v2.33
ChromeDriver v2.33 明确提及以下内容:

支持 Chrome v60-62

您正在使用 chrome=63.0
Selenium 版本我们不知道.

You are using chrome=63.0

Selenium Version is unknown to us.

因此，您使用的 ChromeDriver v2.33 和 Chrome 浏览器 v63.0 之间存在明显的不匹配.因此 ChromeDriver 无法生成新的 Chrome 浏览器 进程.

So there is a clear mismatch between the ChromeDriver v2.33 and the Chrome Browser v63.0 you are using. Hence ChromeDriver is unable to spawn the new Chrome Browser process.

将 ChromeDriver 更新到最近的 v2.35 级别.
将 Chrome 升级到稳定的 Chrome v64.x 级别.(根据 ChromeDriver v2.35 发行说明)
将 Selenium 升级到当前级别 3.9.1 版.
清理并通过您的IDE重新构建您的项目.
清除浏览器缓存.
运行 CCleaner 工具，在执行 之前和之后清除所有操作系统杂务测试套件.

如果您的 Web 浏览器 基础版本太旧，请通过 Web 浏览器" rel="nofollow noreferrer">Revo Uninstaller 使用 Moderate Scan 并安装 Web 浏览器 的最新 GA 发布 版本.
执行您的测试.

Update ChromeDriver to recent v2.35 level.
Upgrade Chrome to stable Chrome v64.x levels. (as per ChromeDriver v2.35 release notes)
Upgrade Selenium to current levels Version 3.9.1.
Clean and Re-Build your project through your IDE.
Clear the Browser Cache.
Run CCleaner tool to wipe off all the OS chores before and after execution of your Test Suite.
If your Web Browser base version is too old, uninstall the Web Browser through Revo Uninstaller with Moderate Scan and install a recent GA Released version of the Web Browser.
Execute your Tests.
