Chrome 无头不起作用
Chrome Headless Doesn't work
我从 developers.google 那里读到 Chrome Headless 说我们可以 运行 Google 没有 UI。引用 link :
Headless Chrome is shipping in Chrome 59. It's a way to run the Chrome
browser in a headless environment. Essentially, running Chrome without
chrome! It brings all modern web platform features provided by
Chromium and the Blink rendering engine to the command line.
Why is that useful?
A headless browser is a great tool for automated testing and server
environments where you don't need a visible UI shell. For example, you
may want to run some tests against a real web page, create a PDF of
it, or just inspect how the browser renders an URL.
这真是一个很棒的功能,所以我对这个很酷的功能做了一些实验。这个想法是通过从 Windows 命令提示符调用 chrome.exe 将快照作为文档站点,如下所示:
chrome --headless --disable-gpu --screenshot https://www.chromestatus.com/
按照这些站点的说明执行几次后。我什么都没有。我没有得到名称为 screenshot.png
的任何图片或屏幕截图,因为文档在 Running with --screenshot will produce a file named screenshot.png in the current working directory.
之前提到了它
从这个文件也说了版本,
Caution: Headless mode is available on Mac and Linux in Chrome 59.
Windows support is coming in Chrome 60. To check what version of
Chrome you have, open chrome://version.
根据之前的建议进行一些检查后,我在 Windows x64 机器上 Chrome 运行 chrome://version
得到了一些结果:
Google Chrome 62.0.3202.94 (Official Build) (64-bit) (cohort: Stable)
Revision 4fd852a98d66564c88736c017b0a0b0478e885ad-refs/branch-heads/3202@{#789}
怎么了?我错过了什么?
谢谢
之后做一些实验。对于 --screenshot
会将图像保存在与 chrome.exe 位置相同的级别,这意味着保存在 Program Files
上。
所以我们需要将参数名称和参数与一个=
结合起来
--screenshot="D:\screen.png" 将起作用,否则 Chrome 将写入其安装文件夹。大设计缺陷,任何软件都不应该使用它的安装文件夹作为工作目录。
这是完整的论点:
chrome --headless --enable-logging --disable-gpu --screenshot="D:\screen.png" "https://www.chromestatus.com/"
