一键复制csdn代码 is a free Chrome browser add-on developed by openHacking. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

This add-on allows users to copy code from CSDN blogs without the need to log in. It provides the convenience of copying code with just one click, either by selecting the code or using the copy button in the top right corner of the code block. Additionally, it removes the "follow the blogger to read the full article" prompt and eliminates the login pop-up.

To use the add-on, simply open any CSDN blog, and you can start copying code immediately. It supports code selection even when you are not logged in to CSDN. The copy button in the top right corner of the code block allows for quick and easy copying. With this add-on, you no longer have to deal with the annoying login pop-up.

For those who are not following the blogger, the add-on removes the "follow the blogger to read the full article" prompt and displays the complete article. If you prefer to disable the automatic code block expansion feature, you can do so in the add-on's popup interface.

Please note that the developer also recommends two other Chrome extensions: "知乎移除登陆" and "ExportGPT 导出插件" for additional functionalities.
