在控制台中生成二维码的简单方法是什么 [英] What is an easy way to generate a QR-Code in a console
问题描述
我的用例如下:我想在 Gajim Windows 中显示我的 OMEMO-Fingerprint 以验证它，但无法让它在那里工作.所以我正在寻找一种从控制台生成特定二维码的简单方法.这样做，应该(我期望)像 xmpp-URI 格式一样简单，这很容易.
My use case is the following: I wanted to show my OMEMO-Fingerprint in Gajim in Windows to verify it, but wasn't able to get it to work there. So I was looking for an easy way to generate a specific QR-Code from console. Doing that, should (I expect) be as easy as the xmpp-URI-format, which is pretty easy.
推荐答案
我发现使用 Python 和 python3-qrcode 可以这样管理:
I found that with Python and python3-qrcode, this is manageable like this:
安装 Python 和所需的模块:
Install Python and the needed modules:
pip install --upgrade pip
pip install cryptography cryptography pillow qrcode setuptools axolotl
使用此在线批处理或 bash 文件 - 它不仅适用于 Windows，还适用于 Linux 等:
Use this onliner batch or bash file - it works not only in windows but also in Linux and more:
python -c "import qrcode; import sys; qrcode.make(sys.argv[1]).save(sys.argv[2])" %1 %2
第一个输入(你当然可以替换%1)应该转换成二维码的string，例如xmpp:user@example.de?omemo-sid-123456789=cf4d1558a8b872e6d8d213be2d3ac447663b3d516509f56536d80b70ca0e8e89 和 %2 目标文件result.png.基本上就是这样.
It takes as the first input (you can replace %1 of course) the string that should be converted to QR, for example xmpp:user@example.de?omemo-sid-123456789=cf4d1558a8b872e6d8d213be2d3ac447663b3d516509f56536d80b70ca0e8e89 and as %2 the destination file as e.g. result.png. That's basically it.
如果你想从文件的内容中生成一个二维码，你可以使用这个:
If you want to generate a QR-Code out of the content of a file, you can use this:
python -c "import qrcode; import sys; qrcode.make(open(sys.argv[1], 'r').read()).save(sys.argv[2])" %1 %2
