download code

github download code is roughly divided into three cases

The downloaded code does not need to include git management nor .git files

At this time, click download directly on github to download. At this time, the downloaded code does not contain git management nor .git files.

The downloaded code should include git management but not configure ssh

If you need git management but do not have ssh permission, you can use git clone repo_url to download the code repo_url is the url of the https card header. At this time, the downloaded code does not have the permission to push. If you need to submit modifications through pull request.

The downloaded code should contain ssh for git management configuration

If you need git management and have ssh permissions, you can use git clone [email protected]:xxx/xxx.git to download the code, so that the downloaded code has push permissions.
