添加电子邮件地址到 GitHub 帐户
GitHub 允许您根据需要为帐户添加多个电子邮件地址。 如果在本地 Git 配置中设置电子邮件地址，您需要将其添加到帐户设置，以将提交连接到帐户。 有关电子邮件地址和提交的更多信息，请参阅“设置提交电子邮件地址”。
注：You cannot verify email addresses from disposable domains. If you'd like to keep your email address private, you can use a GitHub-provided noreply email address. For more information, see "Setting your commit email address on GitHub."
