I didn't like programming before, but now I am an IT fan obsessed with programming. I would like to share some things I have sorted out and optimized here, hoping to help IT fans, with joy and sweat, and at the same time I also hope that everyone can support it. Of course, if you have money to support a money field (support Alipay and WeChat donations, join the it data center buckle group), but have no money to support a personal field, with your support, we will be more motivated and do better, thank you Ladies and gentlemen.
